Speaker 1: Welcome to your deep dive. Today. We're cracking open no
Speaker 1: Starch pen testing Azure to explore the wild world of
Speaker 1: Azure cloud security from a penetration testers perspective. It's like
Speaker 1: getting a sneak peek into the attacker's playbook.
Speaker 2: This book really dives into the unique challenges of securing
Speaker 2: cloud environments, which are vastly different from traditional on premises setups.
Speaker 1: Right, and one thing that stood out to me is
Speaker 1: how critical planning and scoping are in this whole process.
Speaker 1: I mean, nobody wants to end up on the wrong
Speaker 1: side of the law while trying to improve security right.
Speaker 2: Absolutely, Penetration testing without proper authorization and a clearly defined
Speaker 2: scope can have serious legal ramifications. Imagine accidentally disrupting a
Speaker 2: critical service or accessing data you weren't supposed to. That's
Speaker 2: why it's crucial to have a solid plan in place,
Speaker 2: outlining the systems you'll be targeting, the methods you'll use,
Speaker 2: and the timeframe for the assessment.
Speaker 1: And here's where it gets really tricky. The book mentions
Speaker 1: that cloud resources can be physically located in different countries,
Speaker 1: each with its own set of laws and regulations. That
Speaker 1: adds a whole other layer of complexity.
Speaker 2: Definitely, a server could be migrated to a different region
Speaker 2: during testing, potentially landing it into jurisdiction with very different
Speaker 2: cybersecurity laws. It's essential to have a clear understanding of
Speaker 2: where your client's data resides and to comply with all
Speaker 2: relevant regulations.
Speaker 1: Before you even start poking around. There's a lot of
Speaker 1: legal groundwork to cover. Now, let's dive into Azure's deployment models.
Speaker 1: I was surprised to learn that Azure uses both a
Speaker 1: legacy model ASM and a newer role based system AIRM,
Speaker 1: and both are still actively used. What are the security
Speaker 1: implications of having these two models running side by side.
Speaker 2: It's like having two sets of locks on your front door.
Speaker 2: Compromising one user's account might only grant access to a
Speaker 2: portion of the resources under a subscription. A thorough penetration
Speaker 2: test needs to target both models to assess the overall
Speaker 2: security posture.
Speaker 1: That makes sense. So with ASM, you've got your three
Speaker 1: manual service administrator, account administrator, and code administrator. The book
Speaker 1: makes it sound like gaining access to any of these
Speaker 1: roles is basically game over for ASM resources. Is that
Speaker 1: a fair assessment?
Speaker 2: Pretty much co administrator role despite its name, has essentially
Speaker 2: the same privileges as the service administrator. Both roles have
Speaker 2: full control over any ASM created resource.
Speaker 1: Got it, So it's like finding the master key that
Speaker 1: unlocks everything. Now let's talk about ARM. It sounds like
Speaker 1: this newer model is a bit more granular with its
Speaker 1: permissions exactly.
Speaker 2: AIRM utilizes roll test access control, which allows administrators to
Speaker 2: define very specific permissions for users and groups. This means
Speaker 2: that even if an attacker compromises one user's account, they'll
Speaker 2: only have access to the resources they're explicitly authorized to use.
Speaker 1: That's reassuring, But even with these different access models, at
Speaker 1: the end of the day, attackers still need credentials to
Speaker 1: get their foot in the door right.
Speaker 2: The book mentions mimic ants as a particularly sneaky tool
Speaker 2: in the arsenal.
Speaker 1: Mimicats is a powerful post exploitation tool that can extract
Speaker 1: passwords directly from a user's operating system, even when the
Speaker 1: system is offline. It takes advantage of how Windows stores
Speaker 1: credentials in memory.
Speaker 2: That's pretty unsettling. Does that mean any attacker with memicats
Speaker 2: could just grab passwords from any Windows system? Not quite.
Speaker 2: The effectiveness of mimicats depends on various factors, including the
Speaker 2: Windows version and configuration. Newer versions, especially Windows ten Enterprise
Speaker 2: with Credential Guard enabled, store credentials in a more secure,
Speaker 2: isolated environment, making it much harder for tools like mimicats
Speaker 2: to succeed.
Speaker 1: It's like a constant arms race between the attackers and
Speaker 1: the defenders, with each side trying to outsmart the other.
Speaker 1: That begs the question, if an organization is migrating to
Speaker 1: Azure and still has older Windows systems, is that something
Speaker 1: they should be particularly concerned about?
Speaker 2: Absolutely, those older systems could be a prime target for
Speaker 2: attackers using tools like mimicats. It's crucial to prioritize upgrading
Speaker 2: to newer, more secure versions of Windows and implementing robust
Speaker 2: security controls like multi factor authentication.
Speaker 1: Okay, so upgrading your systems and layering on those extra
Speaker 1: security measures is key. But aside from brute force attacks
Speaker 1: with tools like mimicats, what are some other ways attackers
Speaker 1: go after credentials in the cloud.
Speaker 2: Phishing is a perennial favorite. Attackers create convincing fake login
Speaker 2: pages or set up elaborate credential capturing systems to trick users.
Speaker 2: Into revealing their sensitive information.
Speaker 1: That's right. Phishing never seems to go out of style,
Speaker 1: does it. But I imagine phishing attacks targeting cloud environments are
Speaker 1: a bit more sophisticated than your average email scam.
Speaker 2: Right, you bet think spear phishing campaigns specifically designed to
Speaker 2: target Azure administrators or developers with access to sensitive cloud resources.
Speaker 2: These attacks are highly targeted and often leverage social engineering
Speaker 2: techniques to bypass traditional security measures.
Speaker 1: That's scary stuff. It really highlights the need for continuous
Speaker 1: security awareness training for all employees, especially those with privileged access. Now,
Speaker 1: speaking of sensitive information, the book dives deep into Azure
Speaker 1: storage security. It makes it sound like securing storage accounts
Speaker 1: is absolutely paramount.
Speaker 2: You're absolutely right. Azure storage accounts are where organizations keep
Speaker 2: a treasure trove of sensitive data. If an attacker gains access,
Speaker 2: they can recavoc stealing data, manipulating configurations, even injecting malicious code.
Speaker 1: Okay, so it's like the Fort Knox of your Azure environment.
Speaker 1: But we're talking about real world attack scenarios. How are
Speaker 1: attackers actually getting their hands on those storagecout keys in
Speaker 1: the first place.
Speaker 2: Be surprised how often developers accidentally leave those keys exposed
Speaker 2: in source code, repositories or configuration files. It's like leaving
Speaker 2: the keys to your vault hanging on a Pullton board.
Speaker 1: That's incredible. So, aside from accidentally leaving those keys lying around,
Speaker 1: what are some other ways attackers are exploiting Azure storage?
Speaker 2: They might exploit weak access controls like overly permissive permissions
Speaker 2: that allow anyone to read or write data, or or
Speaker 2: they might target specific storage services like queues, which are
Speaker 2: often used for communication between applications.
Speaker 1: Hold on manipulating cues. How does that work and what
Speaker 1: are the potential consequences?
Speaker 2: Imagine a queue used to process orders in an e
Speaker 2: commerce application. An attacker could inject malicious messages into the queue,
Speaker 2: altering prices, redirecting payments, or even causing the application to crash.
Speaker 1: Wow, so a seemingly harmless queue could be a major
Speaker 1: security vulnerability. What are some practical steps developers can take
Speaker 1: to prevent this type of attack?
Speaker 2: Strong authentication and authorization are essential, along with proper input
Speaker 2: validation and sanitization. Think of it like implementing texts and
Speaker 2: balances to ensure only legitimate messages are processed.
Speaker 1: So it's all about building those security checks into the
Speaker 1: application itself, not just relying on perimeter security. That makes
Speaker 1: a lot of sense. Now let's shift gears and talk
Speaker 1: about virtual machine security, or VM security. The book really
Speaker 1: emphasizes how critical it is to lock down those vms,
Speaker 1: and it even details some scary scenarios like attackers obtaining
Speaker 1: VHD images and extracting data from them.
Speaker 2: It's a serious threat, and it's not as difficult as
Speaker 2: you might think. Attackers can download snapshots of vhds using
Speaker 2: freely available tools like Microsoft Azure Storage Exploitate.
Speaker 1: A free tools, So anyone with Internet access can just
Speaker 1: download these VHD images.
Speaker 2: Not exactly, they would still need the storage account key,
Speaker 2: which brings us back to the importance of securing those keys.
Speaker 2: But once they have the key, downloading the VHD is
Speaker 2: just a few clicks away.
Speaker 1: Okay, so that's step one. But once an attacker has
Speaker 1: that VHD image, what can they actually do with it?
Speaker 2: Think of it like stealing a blueprint. They can analyze
Speaker 2: the VHD using forensic tools to extract all sorts of
Speaker 2: sensitive information, including user accounts, passwords, and configuration files.
Speaker 1: That's pretty alarming. So it's like having your entire server
Speaker 1: environment compromised just because a single storage account key was leaked.
Speaker 1: What are some concrete steps organizations can take to protect
Speaker 1: their vhds from this kind of attack.
Speaker 2: Encryption is key here. Azure offers disc encryption, a free
Speaker 2: service that uses BitLocker for Windows vms and dmcrypt for
Speaker 2: Linux vms to fully encrypt the virtual disc. This makes
Speaker 2: it impossible for attackers to analyze the VHD, even if
Speaker 2: they manage to attain it.
Speaker 1: So it's like putting that VHD image in a lock box,
Speaker 1: making it useless to anyone without the key. But what
Speaker 1: about securing the vms themselves? Are there any default security
Speaker 1: features in Azure or is it all up to the
Speaker 1: administrators to configure everything manually.
Speaker 2: Azure vms come with some basic security features enabled by default,
Speaker 2: like firewalls and antivirus software. However, they are not fort
Speaker 2: Knox out of the box. Administrators still need to be
Speaker 2: proactive about configuring security settings, applying updates, and implementing best
Speaker 2: practices like least privilege access right.
Speaker 1: So it's not a set it and forget it scenario.
Speaker 1: You need to be constantly vigilant about securing yours. Now,
Speaker 1: one thing that really stood out to me in the
Speaker 1: book was the potential for attackers to exploit the VM
Speaker 1: password reset option in the Azure portal. How does that
Speaker 1: work and why is it such a concern.
Speaker 2: It's a classic privilege escalation attack. If an attacker gains
Speaker 2: access to the Azure Portal and can target a specific VM,
Speaker 2: they can simply use the password reset feature to gain
Speaker 2: administrative access even without knowing the current password.
Speaker 1: Wow, that sounds like a pretty significant loophole. Are there
Speaker 1: any limitations to this attack or is it a guaranteed
Speaker 1: win for the attacker?
Speaker 2: Oh, they would need access to the Azure Portal in
Speaker 2: the first place, which requires valid credentials. This is where
Speaker 2: strong authentication practices like multi factor authentication in MFA come
Speaker 2: to play. MFA adds an extra layer of security, making
Speaker 2: it significantly harder for attackers to gain unauthorized access.
Speaker 1: So MFA is crucial for protecting those administrative accounts. But
Speaker 1: even with MFA, it's still possible for determined attackers to
Speaker 1: find ways to bypass security measures. What are some other
Speaker 1: defenses organizations can implement to protect against VM password reset attacks.
Speaker 2: Robust logging and monitoring can be incredibly helpful by tracking
Speaker 2: activities like password resets. Security teams can quickly identify and
Speaker 2: investigate any suspicious behavior. Alerting mechanisms can notify administrators of
Speaker 2: any unexpected password changes, allowing for swift action to contain
Speaker 2: potential threats.
Speaker 1: Right, So, it's about having that visibility into what's happening
Speaker 1: in your environment and being able to respond quickly to
Speaker 1: potential threats. But let's assume for a moment that an
Speaker 1: attacker manages to bypass those initial defenses and gains access
Speaker 1: to a VM. What are their next steps? What are
Speaker 1: they likely to do once they're inside.
Speaker 2: Their next move is often to map out the network
Speaker 2: and identify potential targets for further exploitation. They'll investigate firewall rules,
Speaker 2: network configurations, and connected systems to fight weaknesses they can exploit.
Speaker 1: It's like they're scouting the terrain looking for the path
Speaker 1: of least resistance. What are some common misconfigurations that make
Speaker 1: the this reconnaissance process easier for attackers.
Speaker 2: One of the most dangerous misconfigurations is the allow all
Speaker 2: firewall rule. Some administrators, yeah either out of convenience or
Speaker 2: lack of understanding, might allow connections from any IP address,
Speaker 2: essentially leaving the door wide open. For attackers.
Speaker 1: That's a rookie mistake, right, I mean, it seems like
Speaker 1: common sense to restrict access to only authorized IP addresses.
Speaker 1: What about firewalls for specific services like Azure Sql. Are
Speaker 1: those any different?
Speaker 2: Azure Sql firewalls are designed to be more restrictive by default,
Speaker 2: only allowing access from other Azure services. However, developers often
Speaker 2: need to connect from their workstations, which can lead to
Speaker 2: relaxed firewall rules common defined rules that allow connections from
Speaker 2: wide IP ranges, potentially opening up vulnerabilities.
Speaker 1: So it's that balance between security and usability that can
Speaker 1: sometimes create vulnerabilities. What's the best way to strike that balance?
Speaker 1: In this case?
Speaker 2: Administrators need to carefully evaluate each firewall rule, ensuring they
Speaker 2: only grant access to necessary IP addresses. Important regular audits
Speaker 2: and reviews can help identify and eliminate overly permissive rules,
Speaker 2: reducing the attack surface.
Speaker 1: Okay, got it. So it's about being meticulous with those
Speaker 1: firewall configurations and not just taking the easy way out.
Speaker 1: Now we've talked about traditional firewalls, but the book also
Speaker 1: mentions as your web application firewalls or wfs, How are
Speaker 1: those different and what role do they play in securing
Speaker 1: azure environments.
Speaker 2: Unlike traditional firewalls that operate at the network layer, wafs
Speaker 2: sit in front of web applications and analyze incoming traffic
Speaker 2: for malicious patterns. They can block suspicious requests or report incidents,
Speaker 2: acting more like an intrusion detection system than a traditional firewall.
Speaker 1: So they're looking for specific attack signatures and behaviors rather
Speaker 1: than just blocking IP addresses imports. That's pretty cool. What
Speaker 1: are some examples of attacks that a wave might detect
Speaker 1: and block?
Speaker 2: Laways could detect and block common web attacks like sequel injection,
Speaker 2: cross sight scripting, and session hijacking. They can also protect
Speaker 2: against application layer GIDAS attacks and filter traffic based on
Speaker 2: factors like geographic location or device type.
Speaker 1: Wow, so they're quite versatile. But are they a fool
Speaker 1: proof solution or are there ways for attackers to bypass them.
Speaker 2: While waves are incredibly powerful, no security measure is full proof.
Speaker 2: Attackers are constantly evolving their techniques and some sophisticated attacks
Speaker 2: might slip through the cracks. That's why it's essential to
Speaker 2: use waves in conjunction with other security measures and regularly
Speaker 2: update through rule sets to stay ahead of emerging threats.
Speaker 1: So it's back to that layered approach to security. Now,
Speaker 1: let's talk about something that sounds a bit scary, cloud
Speaker 1: to corporate network bridging. I'm guessing this is where things
Speaker 1: can get really risky, especially when you're connecting your cloud
Speaker 1: environment to your internal corporate network.
Speaker 2: It definitely adds another layer of complexity. While features like
Speaker 2: VPNs and express rout are fantastic for enabling hybrid it,
Speaker 2: they can also create a bridge between the cloud and
Speaker 2: the corporate network. If an attacker breaches a public facing
Speaker 2: service in Azure that has VPN connectivity to the corporate network,
Speaker 2: they potentially have a direct path to infiltrate the internal systems.
Speaker 1: That's a frightening thought. It's like leaving a secret backdoor
Speaker 1: into your fortress wide open. What are some stepped organizations
Speaker 1: can take to mitigate this risk and secure those hybrid connections.
Speaker 2: Separation is key. Isolate services that need corporate network access
Speaker 2: from those exposed publicly, ideally keeping them in separate subscriptions.
Speaker 2: And if a service needs both types of access, careful
Speaker 2: design and thorough threat modeling are crucial, followed by rigorous
Speaker 2: tenetration testing to validate the security.
Speaker 1: Okay, so it's all about compartmentalizing and minimizing the attack
Speaker 1: surface as much as possible. But let's dive a little
Speaker 1: deeper into VPN specifically. What are some common attack vectors
Speaker 1: that target azure VPN connections and how can organizations defend
Speaker 1: against them.
Speaker 2: Attackers might try to exploit misconfigured VPN gateways, brute force credentials,
Speaker 2: or even intercept traffic if it's not properly encrypted. They
Speaker 2: might also attempt to create rogue VPN can to gain unauthorized.
Speaker 1: Access, so it's like they're either trying to break into
Speaker 1: the existing tunnel or build their own secret passage. What
Speaker 1: are some telltale signs of a rogue VPN connection that
Speaker 1: security team should be on the lookout for.
Speaker 2: Unusual traffic patterns, unauthorized IP addresses, accessing sensitive resources, or
Speaker 2: an increase in VPN connection attempts, especially outside of normal
Speaker 2: business hours can all be red flags.
Speaker 1: Got it? So monitoring and anomaly detection are critical for
Speaker 1: spotting those suspicious activities. Now, what about express route? It
Speaker 1: sounds like a more robust and secure option than VPNs,
Speaker 1: but are there any specific security considerations organizations should be
Speaker 1: aware of.
Speaker 2: Express route establishes dedicated circuits between a company and Microsoft's
Speaker 2: cloud services, offering a more stable and secure connection than
Speaker 2: the public Internet. However, if an attacker compromises a system
Speaker 2: connected to the Express Route network, they could potentially access
Speaker 2: a wider range of resources, including both Azure and corporate.
Speaker 1: System So the stakes are even higher with Express Route
Speaker 1: given its complexity and cost. What kind of attackers are
Speaker 1: typically interested in targeting these connections.
Speaker 2: Due to the higher barrier to entry attax targeting Express
Speaker 2: Route are usually carried out by sophisticated actors like nation
Speaker 2: states or highly skilled cyber criminals seeking access to high
Speaker 2: value data or critical infrastructure.
Speaker 1: Okay, so these are not your average script kitties. What
Speaker 1: are some defenses against these advanced persistent threats targeting Express
Speaker 1: Route connections?
Speaker 2: Strong authentication and authorization are paramount. Implementing robust network segmentation
Speaker 2: can help limit the impact of a potential breach. Continuous
Speaker 2: monitoring and intrusion detection systems can help identify suspicious activity,
Speaker 2: and having well rehearsed incident response plans can help contain
Speaker 2: and remediate attacks quickly.
Speaker 1: It's all about proactive security measures and being prepared for
Speaker 1: the worst case scenario. Now I'd like to shift gears
Speaker 1: and talk about a service that I'm particularly interested in,
Speaker 1: a service bus. What is this service and what makes
Speaker 1: it a potential target for attackers?
Speaker 2: Dinature service bus is a messaging service that facilitates communication
Speaker 2: between applications. It's attractive to attackers because it can hold
Speaker 2: sensitive information like connection strings and access keys, and it
Speaker 2: can be exploited to disrupt communication or even gain control
Speaker 2: over other Azure services.
Speaker 1: Okay, so it's like a central communication hub, right that
Speaker 1: attackers might try to compromise to gain a foothold in
Speaker 1: the environment. What are some specific attack vectors they might
Speaker 1: use against service bus?
Speaker 2: One common attack is obtaining administrative details such as the
Speaker 2: instance name, resource group, dot URL, and access keys. They
Speaker 2: might employ social engineering, phishing, or exploit vulnerabilities in the
Speaker 2: management interface to steal these credentials.
Speaker 1: So securing those administrative details is absolutely crucial. What are
Speaker 1: some best practices for protecting this information and mitigating those risks?
Speaker 2: Think about implementing strong password policies, multi factor authentication, and
Speaker 2: the principle of least privilege access. Robust logging and monitoring
Speaker 2: can help detect unauthorized access attempts and regular security audits,
Speaker 2: can ensure configurations are up to date.
Speaker 1: Got it. So it's back to those fundamental security principles again.
Speaker 2: Now.
Speaker 1: The book also mentions Azure logic apps, and I have
Speaker 1: to admit I'm not entirely sure what those are. Can
Speaker 1: you explain them and why they might be of interest
Speaker 1: to attackers?
Speaker 2: Logic apps are a cloud tiss service that allows users
Speaker 2: to automate workflows and integrate different applications and services. They're
Speaker 2: essentially building blocks for creating automated processes in the cloud.
Speaker 1: Okay, that makes sense, But how do they fit into
Speaker 1: the security landscape? Are logic apps themselves vulnerable to attacks
Speaker 1: or is it more about how they're used and configured.
Speaker 2: While logic apps themselves might not have a huge attack surface,
Speaker 2: they often cash credentials and access tokens for various services,
Speaker 2: including both Microsoft and third party services. That's what makes
Speaker 2: them attractive to attackers.
Speaker 1: Ah, so it's those cached credentials that are their real price.
Speaker 1: Are there any specific attacks that target logic apps or
Speaker 1: is it more about exploiting misconfigurations and poor security practices.
Speaker 2: It's mainly about exploiting those misconfigurations and weaknesses in how
Speaker 2: logic apps are implemented, attackers might try to gain access
Speaker 2: to the underlying infrastructure, exploit vulnerabilities in the platform itself,
Speaker 2: or use social engineering techniques to trick users into revealing
Speaker 2: sensitive information.
Speaker 1: It's another reminder that even seemingly harmless services can pose
Speaker 1: a security risk if not properly secured. Now, let's move
Speaker 1: on to a service that I'm really intrigued by, as
Speaker 1: your key vault. It sounds like this service is designed
Speaker 1: to be a digital fortress for storing secrets. Is that
Speaker 1: a fair assessment?
Speaker 2: Absolutely? Keyvol provides a secure and centralized platform for storing
Speaker 2: sensitive information like passwords, connection strings, API keys, and certificates.
Speaker 2: It's built with robust security controls to protect these secrets
Speaker 2: from unauthorized access.
Speaker 1: Okay, so it's like the ultimate lock box for your
Speaker 1: most valuable digital assets. But as we've seen with other
Speaker 1: Azure services, every fortress has its potential weaknesses. What are
Speaker 1: some of the vulnerabilities that attackers might target in keyvault?
Speaker 2: Misconfigured access policies are a common vulnerability. If permissions aren't
Speaker 2: properly restricted, users or applications could gain access to secrets
Speaker 2: they shouldn't have. Attackers also look for vulnerabilities in the
Speaker 2: key voult service itself, though Microsoft regularly patches and updates
Speaker 2: the platform to address any known issues.
Speaker 1: So even with a service that's designed for security, it
Speaker 1: all comes down to how it's configured and managed. What
Speaker 1: are some best practices for hardening key vault and ensuring
Speaker 1: the security of the secrets stored.
Speaker 2: Within Tightly controlling access is paramount Role based access control
Speaker 2: RBAC allows administrators to grank granular permissions to users and applications,
Speaker 2: ensuring they only have access to the specific secrets they need.
Speaker 2: Pre Encrypting secrets before storing them in key vault adds
Speaker 2: an extra layer of protection.
Speaker 1: Pre encrypting secrets. That's interesting. Why is that recommended and
Speaker 1: what additional benefits does it provide?
Speaker 2: It ensures that even if an attacker gains access to
Speaker 2: the key vault, they won't be able to easily decrypt
Speaker 2: the secrets without the additional encryption key. Think of like
Speaker 2: having a lock box inside a vault.
Speaker 1: That's a great analogy. So it's like defense in depth
Speaker 1: applied to secrets management. Now, what about logging? Is that
Speaker 1: important for key vault security as well?
Speaker 2: Absolutely? Enabling logging provides an audit trail of all activities
Speaker 2: related to keyfold including key enumeration, creation, reads, rights, and deletions.
Speaker 2: This allows security teams to monitor for any suspicious activity
Speaker 2: and identify potential breaches.
Speaker 1: So it's like having a security camera inside the vault
Speaker 1: recording everything that happens. Now, let's talk about how attackers
Speaker 1: typically try to access keyvoult. Are there any common techniques
Speaker 1: they use to get their hands on those valuable secrets.
Speaker 2: They might try to exploit stolen credentials, brute force access keys,
Speaker 2: or leverage vulnerabilities and applications or systems that have access
Speaker 2: to key vault. Social Engineering attacks are also a possibility,
Speaker 2: as attackers might try to trick users into revealing secrets
Speaker 2: or granting them access.
Speaker 1: So it's another reminder that even with the secure service
Speaker 1: like key vault, human error or social engineering can still
Speaker 1: be a weak link. Now, I'd like to touch on
Speaker 1: something that seems particularly important, accessing key vault from other
Speaker 1: Azure services. Why is this important from a security perspective
Speaker 1: and what risks does it introduce.
Speaker 2: While allowing other Azure services to access key voult offers
Speaker 2: convenience and flexibility, it can also increase the attack surface.
Speaker 2: For example, If a user has administrative access to a
Speaker 2: virtual machine that's authorized to access key vault, they might
Speaker 2: be able to retrieve secrets they would normally have permission
Speaker 2: to see. AH.
Speaker 1: So it's about the potential for privilege escalation an unauthorized
Speaker 1: access to sensitive information. What are some strategies for mitigating
Speaker 1: this risk and ensuring that only authorized services and users
Speaker 1: can access key vault.
Speaker 2: Carefully consider which services need access to key vault and
Speaker 2: grant them the least privilege necessary. Regularly review access policies
Speaker 2: and remove any unnecessary permissions. Implementing strong authentication and authorization
Speaker 2: mechanisms for all services that interact with key vault is
Speaker 2: also essential.
Speaker 1: It's all about minimizing the attack surface and ensuring that
Speaker 1: every access request is properly vetted. Now, I know you're
Speaker 1: a big advocate for using key vault to address common
Speaker 1: pentist findings. Can you give us a real world example
Speaker 1: of how you might use key vault to remediate a
Speaker 1: security vulnerability.
Speaker 2: Absolutely. Imagine you discovered during a penetration test that an
Speaker 2: application is storing sensitive credentials in plaintext within its configuration files,
Speaker 2: recommending that the client migrate those credentials to key vault
Speaker 2: would be a significant improvement.
Speaker 1: That makes perfect sense. It's like taking those loose keys
Speaker 1: lying around and putting them in a secure lock box
Speaker 1: where they belong. Now, let's move on to another area
Speaker 1: that attackers often target, azure web apps. What are some
Speaker 1: common vulnerabilities that you find in these applications during pentists?
Speaker 2: Weak authentication mechanisms are a common issue. Many web apps
Speaker 2: rely on simple username and password combinations, which is susceptible
Speaker 2: to brute force attacks or credential stuffing. Attackers also target
Speaker 2: misconfigured web servers, looking for exposed directories, sensitive files, or
Speaker 2: vulnerabilities in the application code itself.
Speaker 1: So it's a combination of weak authentication, misconfigured servers, and
Speaker 1: application level vulnerabilities. What are some telltale signs that a
Speaker 1: web app might be poorly secured? From an attacker's perspective.
Speaker 2: Air messages that reveal sensitive information, default login pages or
Speaker 2: directory listings that expose the site's structure can all be
Speaker 2: indicators of poor security. Attackers also look for outdated software versions,
Speaker 2: known vulnerabilities, and web frameworks or misconfigured security settings.
Speaker 1: Got it, So it's a combination of obvious clues and
Speaker 1: more subtle technical details that attackers look for. What are
Speaker 1: some specific attack techniques that target Azure web apps?
Speaker 2: Sql injection, cross sites scripting, and session hijacking are common
Speaker 2: attacks that exploit vulnerabilities in the web application code. Attackers
Speaker 2: might also try to upload malicious files, gain control of
Speaker 2: the web server, or even launch denial of service attacks.
Speaker 1: So it's a wide range of attacks, from simple exploits
Speaker 1: to more sophisticated techniques. What are some key steps that
Speaker 1: developers can take to protect their web apps from these
Speaker 1: threats and build more secure applications from the ground up.
Speaker 2: Input validation is crucial to prevent attacks like seqal injection
Speaker 2: and cross site scripting. They should also keep their software
Speaker 2: up to date, use strong authentication mechanisms, and implement robust
Speaker 2: error handling and logging to detect and respond to attacks.
Speaker 1: It's about building secure code from the ground up and
Speaker 1: implementing defenses at multiple layers. No one thing that caught
Speaker 1: my eye in the book was the discussion of Azure
Speaker 1: user deployment credentials. What are those and why are they
Speaker 1: potentially dangerous?
Speaker 2: Each Azure user can create a deployment account to manage
Speaker 2: files in their web apps across all subscriptions this account bypassed.
Speaker 2: This is the normal authentication process and provides direct access
Speaker 2: to the app server's file system.
Speaker 1: WHOA, that sounds like a major security risk. Why would
Speaker 1: anyone design a system like that. It seems like it's
Speaker 1: just asking for trouble.
Speaker 2: It's intended to streamline deployments and simplify administrative tasks. However,
Speaker 2: it could be a serious security vulnerability if these deployment
Speaker 2: credentials are compromised or not properly managed.
Speaker 1: So it's another example of convenience versus security, and sometimes
Speaker 1: those design decisions can have unintended consequences. What can attackers
Speaker 1: actually do if they get their hands on these deployment credentials?
Speaker 1: What kind of damage can they inflict?
Speaker 2: They could modify website files, upload malicious code, steal sensitive information,
Speaker 2: or even gain control of the underlying web server.
Speaker 1: That's a nightmare scenario. What are some recommendations for mitigating
Speaker 1: the risks associated with these deployment credentials and preventing them
Speaker 1: from falling into the wrong hands.
Speaker 2: You strong unique passwords for these accounts and store them securely.
Speaker 2: Regularly rotate credentials, especially after employees leave the organization, Enable
Speaker 2: multi factor authentication if possible, and perhaps most importantly, educate
Speaker 2: developers about the risks associated with these credentials and the
Speaker 2: importance of following security best practices.
Speaker 1: So it's a combination of technical controls, administrative processes, yeah,
Speaker 1: and user education. Now let's switch gears and talk about
Speaker 1: something that sounds a bit like a digital detective story
Speaker 1: investigating artifacts on web app servers. What kinds of artifacts
Speaker 1: are we talking about here and what secrets can they reveal?
Speaker 2: Think about files, logs, configuration settings, and other traces of
Speaker 2: activity on the server. They can provide valuable insights into
Speaker 2: what's happening on the system, revealing evidence of attacks, compromise accounts,
Speaker 2: spoolen data, or misconfigured settings.
Speaker 1: So it's like piecing together a puzzle to understand what
Speaker 1: happened on the server. What are some techniques for examining
Speaker 1: these artifacts and uncovering those hitting clues?
Speaker 2: Manually reviewing log files, analyzing configuration files and using for
Speaker 2: tools to examine the file system or common techniques. Attackers
Speaker 2: often search for specific keywords, patterns, or anomalies that might
Speaker 2: indicate suspicious activity.
Speaker 1: Okay, So it's a combination of manual analysis and automated
Speaker 1: tools to dig through those digital breadcrumbs. What are some
Speaker 1: interesting artifacts that you've discovered during your investigations and what
Speaker 1: stories did they tell?
Speaker 2: In one case, I discovered a hidden directory on a
Speaker 2: web server that contained backups of the website's database, including
Speaker 2: sensitive customer information. This highlighted the importance of securing backups
Speaker 2: and ensuring they are not accessible from the public Internet.
Speaker 2: In another case, I found a log file that recorded
Speaker 2: every command executed by a compromise administrator account, revealing the
Speaker 2: extent of the attacker's access and actions.
Speaker 1: Wow, those are some valuable insights. It shows how artifact
Speaker 1: analysis can uncover hidden threats and provide a deeper understanding
Speaker 1: of an attack. Now, let's move on to a service
Speaker 1: that sounds like it could be either a powerful tool
Speaker 1: or a dangerous weapon, as your automation. How can attackers
Speaker 1: exploit this service for their own malicious purposes?
Speaker 2: As your automation uses run books, which are essentially scripts
Speaker 2: that automate various tasks to manage and configure Azure resources,
Speaker 2: attackers might try to gain access to these run books
Speaker 2: to modify their behavior, steal sensitive information, or even execute
Speaker 2: commands on target systems.
Speaker 1: No, it's like hijacking those automation scripts to do their bidding.
Speaker 1: What are some specific attack vectors that target Azure automation
Speaker 1: and what weaknesses do attackers look for.
Speaker 2: They might exploit stolen credentials, leverage vulnerabilities in the automation
Speaker 2: service itself, or inject malicious code into existing run books.
Speaker 2: Social engineering attacks are also a possibility, as attackers might
Speaker 2: try to trick users into granting them access to automation
Speaker 2: accounts or revealing sensitive information.
Speaker 1: So it's another reminder that even seemingly harmless automation tools
Speaker 1: can be weaponized if not properly secured. What are some
Speaker 1: best practices for hardening Azure automation and preventing these attacks?
Speaker 2: Strong authentication, least privileged access, and regular security audits are crucial.
Speaker 2: Monitoring run book activity, implementing version control, and restricting access
Speaker 2: to sensitive run books that perform critical tasks can also
Speaker 2: significantly enhance security.
Speaker 1: Okay, so it's all about layering those security controls and
Speaker 1: implementing those robust management practices. Now, within Azure automation, attackers
Speaker 1: often target specific assets like credentials. What are some techniques
Speaker 1: they use to obtain and exploit these credentials?
Speaker 2: They might try to extract credentials from run books, exploit
Speaker 2: vulnerabilities in the credential storage mechanisms, or use social engineering
Speaker 2: techniques to trick users into revealing sensitive information.
Speaker 1: It's about targeting both the technical storage of credentials and
Speaker 1: the human element, which we know can often be the
Speaker 1: weakest link. What are some commonplaces within Azure automation where
Speaker 1: attackers might find those valuable credentials?
Speaker 2: They might find credentials embedded within run book code, stored
Speaker 2: as variables, or even stored in external credential vaults. Attackers
Speaker 2: use automated tools to scan for these credentials and manually
Speaker 2: review runbook code and configuration files looking for any signs
Speaker 2: of weakness.
Speaker 1: Got it. So it's a combination of automated scanning and
Speaker 1: manual analysis, like a digital treasure hunt for those valuable secrets.
Speaker 1: What are some best practices for protecting credentials within Azure
Speaker 1: automation and making it much harder for attackers to find them.
Speaker 2: You strong unique passwords for all accounts, avoid hard coding
Speaker 2: credentials within run books, and store sensitive credentials in secure
Speaker 2: credential vaults. Regularly rotate credentials, and implement multifag or authentication
Speaker 2: whenever possible.
Speaker 1: So it's all about those fundamental security principles again. Now
Speaker 1: let's shift gears to another type of asset that attackers
Speaker 1: often target within Azure Automation, certificates. What makes certificates so
Speaker 1: valuable to attackers?
Speaker 2: Certificates are used for authentication and encryption, so obtaining a
Speaker 2: valid certificate can grant an attacker access to sensitive systems
Speaker 2: or allow them to decrypt confidential data. They might also
Speaker 2: use stolen certificates to impersonate legitimate users or services, making
Speaker 2: their attacks much more difficult to detect.
Speaker 1: So in Google fun, it's like stealing a digital identity
Speaker 1: card that grants them access to sensitive systems and data.
Speaker 1: What are some common techniques attackers use to obtain certificates
Speaker 1: from Azure Automation.
Speaker 2: Similar to your credentials. They might try to extract certificates
Speaker 2: from run books, exploit vulnerabilities in the certificate storage mechanism,
Speaker 2: or use social engineering techniques to trick users into handing
Speaker 2: over certificates.
Speaker 1: So it's a similar playbook to the one they use
Speaker 1: for obtaining credentials. What are some best practices for protecting
Speaker 1: certificates within Azure automation and preventing those attacks.
Speaker 2: Securely store your certificates, use strong passwords to protect private keys,
Speaker 2: and regularly rotate those certificates. Implement least privilege access, and
Speaker 2: carefully consider which run books and users need access to
Speaker 2: sensitive certificates.
Speaker 1: Okay, so it's all about minimizing the attack surface and
Speaker 1: implementing those robust security controls. Now, you mentioned earlier that
Speaker 1: you often use Azure automation to gather information during a
Speaker 1: penetration test. Can you give us an example of how
Speaker 1: you might do that. How does Azure automation become a
Speaker 1: tool in the penetration tester's arsenal.
Speaker 2: Absolutely, I might create a ren book that enumerates all
Speaker 2: virtual machines in a subscription, retrieves their public IP addresses,
Speaker 2: and checks if any of them have open ports that
Speaker 2: can be vulnerable to attack. This information helps me understand
Speaker 2: the client's attack surface and identify potential targets for further investigation.
Speaker 1: That's the clever use of Azure automation. It's like having
Speaker 1: an automated reconnaissance team at your fingertips. Now, let's transition
Speaker 1: to another crucial aspect of AZRA security, monitoring and logging
Speaker 1: why are these so essential for detecting and responding to
Speaker 1: attacks in the cloud?
Speaker 2: Monitoring gives security teams a continuous view of their Azure environment,
Speaker 2: allowing them to look for any unusual activity that might
Speaker 2: indicate an attacking. Provides a detailed record of events which
Speaker 2: can be analyzed to understand the scope and impact of
Speaker 2: a breach and identify the attacker's tactics, techniques, and procedures.
Speaker 1: So monitoring is like having security cameras and guards patrolling
Speaker 1: your digital fortress, while logging is like having a detailed
Speaker 1: security log that records every event.
Speaker 2: What are some key Azure services and tools that provide
Speaker 2: these monitoring and logging capabilities? As your Security center provides
Speaker 2: a centralized view of security alerts and recommendations, well, Operations
Speaker 2: Management Suite OMS collects logs and enables centralized management of systems.
Speaker 2: Both solutions offer powerful capabilities for monitoring and analyzing events,
Speaker 2: detecting threats, and responding to incidents.
Speaker 1: Okay, so they're like the central command centers for Azure security,
Speaker 1: giving you that bird's eye view of what's happening. Now,
Speaker 1: let's dive into Azure Security Center specifically. What are some
Speaker 1: of its key features? That make it so valuable for
Speaker 1: security teams.
Speaker 2: It provides a unified view of security across your entire
Speaker 2: a environment, offering insights into vulnerabilities, threats, and recommendations for
Speaker 2: improving your security posture. It also includes advanced threat detection capabilities,
Speaker 2: leveraging machine learning and behavioral analytics to identify suspicious activity

Speaker 1: some examples of threats that Security Center might detect.
Speaker 2: It can detect malwur infections, brute force attacks, suspicious network connections,
Speaker 2: and anomalist user behavior. It also lurns you to misconfigurations,
Speaker 2: vulnerabilities and compliance violations.
Speaker 1: Wow, it sounds like a pretty comprehensive security solution. But
Speaker 1: are there any limitations to Security Center? Is it a
Speaker 1: silver bullet for Azure security or is there more to it?
Speaker 2: Well, security Center is a powerful tool, it's not a
Speaker 2: silver bullet. It's important to remember that security is a
Speaker 2: continuous process and Security Center is just one part of
Speaker 2: a layered security strategy. Organizations still need to implement other
Speaker 2: security measures, such as strong authentication, network segmentation, and regular
Speaker 2: security audits.
Speaker 1: Right, So, it's about using Security Center as a force multiplier,
Speaker 1: not a replacement for other security best practices. Now, let's
Speaker 1: talk about how security teams can effectively leverage Security Center's
Speaker 1: detection capabilities to identify and respond to attacks. What are
Speaker 1: some key things they should be looking for.
Speaker 2: Pay close attention to security alerts, especially those marked as
Speaker 2: high severity. Analyzing the details of these alerts can provide
Speaker 2: valuable insights into the nature of the attack, the affected resources,
Speaker 2: and the attackers tactics.
Speaker 1: It's like treating each alert as a potential lead in
Speaker 1: a digital investigation. What kind of information might security teams
Speaker 1: find in those alerts and how can they use that
Speaker 1: information to piece together what happened.
Speaker 2: Alerts might contain information about the source IP address of
Speaker 2: the attack, the compromised user account, the affected resource, the
Speaker 2: type of attack, and the time of the incident. They
Speaker 2: might also include recommendations from mitigating the attack and preventing
Speaker 2: future occurrences.
Speaker 1: Got it. So, it's like a mini incident report for
Speaker 1: each potential security event, giving you a starting point for
Speaker 1: your investigation. Now, aside from reacting to alerts, how can
Speaker 1: security teams use Security Center proactively to strengthen their security
Speaker 1: posture and stay ahead of the attackers.
Speaker 2: Security Center's recommendations feature is a gold mine. It helps

Speaker 1: talk about how security teams can actually use OMS to
Speaker 1: investigate and respond to security incidents. What are some of
Speaker 1: the common steps involved in that process.
Speaker 2: The first step is often to identify the affected systems
Speaker 2: and users by analyzing log data. Once they have a
Speaker 2: better understanding of the scope of the incident, they can
Speaker 2: start digging deeper into the attackers tactics and techniques. OMS
Speaker 2: can help with this by providing detailed information about the
Speaker 2: attackers' activity, such as the commands they executed, the files
Speaker 2: they accessed, and the network connections they made.
Speaker 1: So it's like following the attackers digital footprints through the logs,
Speaker 1: trying to retrace their steps and understand their motives. What
Speaker 1: are some examples of log data that might be particularly
Speaker 1: useful for this type of investigation? What should security teams
Speaker 1: be looking for in those logs?
Speaker 2: Security event logs from Windows systems, audit logs from Azure services,
Speaker 2: network traffic logs, and web server logs can all provide
Speaker 2: valuable insights into an attacker's activity.
Speaker 1: Got it, So, it's about gathering as much relevant log
Speaker 1: data as possible to build a complete picture of the
Speaker 1: attack and understand the attacker's movements. Now, once security teams
Speaker 1: have identified the attacker's actions, what are some steps they
Speaker 1: can take to contain the damage and remediate the incident?
Speaker 1: How do they go from investigation to action?
Speaker 2: They might isolate, compromise systems, reset compromised accounts, remove malicious code,
Speaker 2: batch vulnerabilities, and strengthen security configurations. OMS can assist with
Speaker 2: these tasks by providing tools for automating incident response workflows
Speaker 2: and integrating with other security solutions.
Speaker 1: So it's about taking swift action to stop the bleeding
Speaker 1: and then implementing long term fixes to prevent similar attack
Speaker 1: from happening again. Now within OMS, there's a feature called
Speaker 1: log search that sounds incredibly powerful for security investigations. What
Speaker 1: makes this feature so valuable? What capabilities does it offer
Speaker 1: that set it apart.
Speaker 2: Log search lets security teams query massive amounts of log
Speaker 2: data using a powerful query language. They can use this
Speaker 2: feature to search for specific events, identify patterns, and correlate
Speaker 2: data from multiple sources to uncover hidden threads that might
Speaker 2: not be visible at first glance.
Speaker 1: It's like having a search engine for your security logs,
Speaker 1: allowing you to sift through that mountain of data and
Speaker 1: find those needles in the haystack. What are some examples
Speaker 1: of queries that security teams might use for investigations? What
Speaker 1: are they looking for in that data?
Speaker 2: They might search for log in attempts from unusual IP addresses,
Speaker 2: failed log in attempts with common passwords, or access to
Speaker 2: sensitive files by unauthorized users. They can also use log
Speaker 2: search to correlate events across multiple systems, such as looking
Speaker 2: for a series of events that might indicate a lateral
Speaker 2: movement at names where an attacker is hopping from one
Speaker 2: system to another within the network.
Speaker 1: Okay, so it's about using log search to hunt for
Speaker 1: those subtle clues that might otherwise go unoticed, those patterns
Speaker 1: that reveal an attacker's true intentions. Now, aside from log search,
Speaker 1: what are some other features in OMS that are particularly
Speaker 1: useful for security monitoring and incident response? What other tools
Speaker 1: do security teams have at their disposal? Within OMS?
Speaker 2: OMS includes security solutions that provide pre built dashboards, alerts,
Speaker 2: and reports for specific security scenarios. For example, the thread
Speaker 2: Intelligence solution provides insights into known threats and vulnerabilities, while
Speaker 2: the Malware Assessment solution helps identify and remove malware from
Speaker 2: your systems.
Speaker 1: So it's about leveraging those pre built solutions to automate
Speaker 1: common security tasks and streamline incident response, making those security
Speaker 1: teams more efficient and effective. Now, what about automating responses
Speaker 1: to security events? Can OMS help with that as well?
Speaker 1: Can you take those alerts and turn them into automated action?
Speaker 2: ABSOLUTELYS allows you to create alerts that trigger automated responses
Speaker 2: when specific events occur. For instance, you could create an
Speaker 2: alert that automatically isolates a virtual machine if it's infected
Speaker 2: with malware, or blocks a suspicious IP address if it's
Speaker 2: attempting to brute force a user account.
Speaker 1: That's incredible. It's like having an automated security guard that
Speaker 1: takes action based on predefined rules, responding to threats in
Speaker 1: real time without human intervention. Now, the book also mentions
Speaker 1: a tool called the Secure DevOps Kit. What is this
Speaker 1: kit and how does it contribute to securing azure environments?
