WEBVTT 1 00:00:00.040 --> 00:00:01.560 Welcome to our deep dive. Everyone. 2 00:00:02.120 --> 00:00:05.559 It's all about wireless network security today. And you know what, 3 00:00:05.599 --> 00:00:08.160 you've given us a really interesting pile of materials to 4 00:00:08.199 --> 00:00:10.599 dig into. So from what I inderstand, you've been spending 5 00:00:10.640 --> 00:00:12.640 some time trying to figure out how to keep your 6 00:00:12.679 --> 00:00:15.400 data safe when you're on wireless networks. And that's a 7 00:00:15.439 --> 00:00:18.359 pretty smart move, you know, especially these days because you're 8 00:00:18.440 --> 00:00:21.559 using your devices everywhere at work, out in public. So 9 00:00:21.640 --> 00:00:23.359 maybe to kick things off, could you just give us 10 00:00:23.399 --> 00:00:26.359 a super quick overview of the kinds of wireless networks 11 00:00:26.359 --> 00:00:26.839 that we're going to. 12 00:00:26.839 --> 00:00:27.280 Be looking at. 13 00:00:27.480 --> 00:00:29.719 Sure, Yeah, you know, we often use that term wireless 14 00:00:29.760 --> 00:00:31.920 network like it's one thing, but actually there are a 15 00:00:31.960 --> 00:00:35.000 bunch of different types with our own security considerations. So 16 00:00:35.240 --> 00:00:38.560 you know, we've got doubly lands more common lin Hiss WiFi, 17 00:00:38.600 --> 00:00:40.960 and we'll be looking at those a lot today, super 18 00:00:41.000 --> 00:00:43.640 common for home networks and public hot spots of course. 19 00:00:43.960 --> 00:00:46.280 Then there's Bluetooth, which you use all the time, I'm sure, 20 00:00:46.320 --> 00:00:50.000 mostly for short range connections like headphones smart home devices. 21 00:00:50.600 --> 00:00:54.439 And then NFC or near field communication, which allows for 22 00:00:54.520 --> 00:00:58.000 really close range communications, so that's for things like contactless payments. 23 00:00:58.320 --> 00:01:01.159 Oh and we can't forget about infra, which seems a 24 00:01:01.200 --> 00:01:03.679 little outdated but still has its uses even today, like 25 00:01:03.799 --> 00:01:04.879 TV remotes and stuff. 26 00:01:04.959 --> 00:01:07.359 Yeah, it's interesting how each of these technologies has really 27 00:01:07.359 --> 00:01:10.040 found its own little place in the world. But I 28 00:01:10.079 --> 00:01:12.319 got to say, for me, the security aspect is what 29 00:01:12.480 --> 00:01:15.120 really grabs my attention. And you know, speaking of w LANCE, 30 00:01:15.319 --> 00:01:18.640 I was going through Wireless Network Security second Edition and 31 00:01:18.680 --> 00:01:20.280 I saw this stat that kind of freaked me out. 32 00:01:20.280 --> 00:01:23.280 It said something like over sixty percent of public Wi 33 00:01:23.280 --> 00:01:25.599 Fi networks are vulnerable to hacking. 34 00:01:25.879 --> 00:01:28.959 Yeah, unfortunately that's true. Public Wi Fi can be a 35 00:01:28.959 --> 00:01:31.200 bit of a minefield when it comes to security. I 36 00:01:31.239 --> 00:01:33.599 think a lot of people don't even realize that using 37 00:01:33.640 --> 00:01:36.920 public Wi Fi without the right protection, it's kind of 38 00:01:36.959 --> 00:01:40.239 like writing your sensitive information on a postcard. Anyone can 39 00:01:40.239 --> 00:01:40.599 read it. 40 00:01:40.719 --> 00:01:43.959 That's a really good analogy. So okay, then how do 41 00:01:44.040 --> 00:01:46.719 we avoid ending up, as you know, one of those 42 00:01:46.760 --> 00:01:48.400 Wi Fi eavesdropping victims. 43 00:01:48.439 --> 00:01:50.239 Well, one of the best ways is to use a 44 00:01:50.439 --> 00:01:53.560 VPN or virtual private network. 45 00:01:54.079 --> 00:01:56.159 Now, I've heard of VPNs before, but I'll be honest, 46 00:01:56.239 --> 00:01:57.560 I'm not really sure how they work. 47 00:01:57.840 --> 00:02:01.560 A VPN creates like this secure encrypted tunnel between your 48 00:02:01.560 --> 00:02:04.159 device and the Internet, So it basically makes all your 49 00:02:04.200 --> 00:02:06.680 activity online invisible to anyone who might be trying to 50 00:02:06.719 --> 00:02:09.159 snoop on that public Wi Fi. Think of it like 51 00:02:09.199 --> 00:02:11.479 having a private conversation, but you're in a really crowded room. 52 00:02:11.479 --> 00:02:12.599 No one else can hear what you're saying. 53 00:02:12.800 --> 00:02:14.479 Okay, that actually makes a lot of sense. I'm definitely 54 00:02:14.479 --> 00:02:16.240 putting get a VPN on my to do list. But 55 00:02:16.319 --> 00:02:18.240 let's rewind a little bit. How did we even get 56 00:02:18.240 --> 00:02:21.400 to this point where using public Wi Fi is considered 57 00:02:21.439 --> 00:02:24.039 so risky. I know that earlier w lands used to 58 00:02:24.039 --> 00:02:28.479 rely on this method called FHSS or frequency hopping spread spectrum. 59 00:02:28.520 --> 00:02:31.319 I think it was is that where the vulnerabilities came from. 60 00:02:31.560 --> 00:02:38.080 Well, FASIS itself. It wasn't inherently insecure, you know, especially 61 00:02:38.080 --> 00:02:40.400 for its time. Actually it was a pretty innovative approach. 62 00:02:40.439 --> 00:02:43.159 You know, the signal jumps really fast between different frequencies, 63 00:02:43.400 --> 00:02:46.560 which made it more difficult to intercept. The real problem 64 00:02:46.560 --> 00:02:49.479 arose with those early encryption protocols that they were using, 65 00:02:49.520 --> 00:02:53.039 like WEP, which stands for Wired Equivalent Privacy. 66 00:02:53.360 --> 00:02:55.520 Oh, so it wasn't the hopping between frequencies that was 67 00:02:55.560 --> 00:02:58.960 the issue. Was how they were protecting the data itself exactly. 68 00:02:59.319 --> 00:03:02.680 WP had pretty big weaknesses in its encryption algorithms, which 69 00:03:02.719 --> 00:03:05.759 made it relatively easy for attackers to crack. And that's 70 00:03:05.800 --> 00:03:07.759 actually what led to the rise of war driving, you know, 71 00:03:07.759 --> 00:03:10.240 where people would drive around with laptops searching for and 72 00:03:10.319 --> 00:03:12.560 exploiting vulnerabilities in these networks. 73 00:03:12.719 --> 00:03:14.680 Wow, I had no idea it was that easy back then. 74 00:03:15.199 --> 00:03:18.560 But what about now? Have things improved with these newer 75 00:03:18.560 --> 00:03:20.080 protocols like WPA two. 76 00:03:20.240 --> 00:03:23.439 Oh yeah, WPA two and now WPA three are way 77 00:03:23.520 --> 00:03:27.759 more robust than WEP was. They use much stronger encryption 78 00:03:27.840 --> 00:03:31.039 algorithms and they require more secure authentication, which makes it 79 00:03:31.080 --> 00:03:32.719 a lot harder for attackers to get in. 80 00:03:32.840 --> 00:03:34.639 Okay, good to know. So if I see a Wi 81 00:03:34.639 --> 00:03:38.080 Fi network that's using WPA two or WPA three, I 82 00:03:38.080 --> 00:03:40.080 can feel a bit more confident about connecting. 83 00:03:40.680 --> 00:03:43.080 Yeah, you can feel better, but it's still super important 84 00:03:43.080 --> 00:03:46.319 to be cautious, especially on those public networks. Even with 85 00:03:46.400 --> 00:03:50.039 the stronger encryption, there are still potential vulnerabilities that are 86 00:03:50.080 --> 00:03:52.080 really determined attacker could try to exploit. 87 00:03:52.280 --> 00:03:55.240 Okay, So it's not just about the encryption protocol itself, 88 00:03:55.520 --> 00:03:58.680 but also about being careful about the network I'm connecting 89 00:03:58.680 --> 00:03:59.360 to exactly. 90 00:03:59.360 --> 00:04:01.599 And this is where your concerns about using devices in 91 00:04:01.639 --> 00:04:05.520 public spaces are really important, because smartphones in particular are 92 00:04:05.520 --> 00:04:08.080 becoming a much bigger target for hackers these days. 93 00:04:08.319 --> 00:04:10.759 That's kind of scary to think about, considering how much 94 00:04:10.800 --> 00:04:13.439 personal information we keep on our phones these days. What 95 00:04:13.560 --> 00:04:14.719 makes them so vulnerable? 96 00:04:14.879 --> 00:04:17.519 Well, you know, smartphones are basically like mini computers. Now. 97 00:04:17.519 --> 00:04:19.639 They connect to all these different wireless networks, and they 98 00:04:19.720 --> 00:04:22.360 run all sorts of apps, and each of those connections 99 00:04:22.360 --> 00:04:24.519 and each of those apps, they all represent a potential 100 00:04:24.680 --> 00:04:25.879 entry point for an attacker. 101 00:04:26.439 --> 00:04:29.439 So it's not just about protecting the phone itself. It's 102 00:04:29.480 --> 00:04:34.000 also about being aware of what apps I'm using and 103 00:04:34.040 --> 00:04:36.319 what networks I'm connecting to exactly. 104 00:04:36.519 --> 00:04:39.079 And then let's not forget about the physical security of 105 00:04:39.120 --> 00:04:42.399 the device itself. You know, a lost or stolen phone 106 00:04:42.439 --> 00:04:46.680 can also lead to compromise data if it's not properly protected. 107 00:04:46.839 --> 00:04:48.720 Man, it seems like they are all these layers of 108 00:04:48.759 --> 00:04:51.079 security to think about. But I'm glad we're talking about 109 00:04:51.079 --> 00:04:52.800 all this because I'm realizing now there's a lot I 110 00:04:52.839 --> 00:04:55.959 didn't even know. Speaking of different layers I noticed one 111 00:04:56.000 --> 00:04:59.839 of the sources we have here highlighted BlackBerry's kind of 112 00:05:00.079 --> 00:05:02.399 unique approach to security. Can you talk a little bit 113 00:05:02.439 --> 00:05:02.800 about that. 114 00:05:03.040 --> 00:05:07.800 Yeah, BlackBerry, or rather rim their manufacture, they've always been 115 00:05:07.839 --> 00:05:11.120 super focused on security, even in those early days of smartphones, 116 00:05:11.720 --> 00:05:14.680 and they adopted this philosophy that centered around something called 117 00:05:14.720 --> 00:05:20.600 symmetric key cryptography, and that aims to ensure the confidentiality, integrity, 118 00:05:20.600 --> 00:05:22.439 and authenticity of data. 119 00:05:22.480 --> 00:05:25.480 Okay, I have to admit those terms sound a little intimidating. 120 00:05:25.839 --> 00:05:27.680 Could you maybe break those down for me a little bit, 121 00:05:27.680 --> 00:05:28.800 make them easier to understand? 122 00:05:28.839 --> 00:05:31.839 Sure, So think of confidentiality like sending a letter. You 123 00:05:31.879 --> 00:05:34.279 put it in a sealed envelope and only the person 124 00:05:34.319 --> 00:05:37.240 you sent it to you can open it. Integrity that's 125 00:05:37.279 --> 00:05:39.439 making sure that the letter hasn't been tampered with while 126 00:05:39.439 --> 00:05:43.560 it's being delivered. And then authenticity that means verifying that 127 00:05:43.600 --> 00:05:45.920 the sender is actually who they say they are. 128 00:05:46.160 --> 00:05:49.800 So it's like this three pronged approach to keeping information secure, 129 00:05:50.319 --> 00:05:52.399 keep it secret, make sure it's not messed with, and 130 00:05:52.439 --> 00:05:53.560 confirm where it came from. 131 00:05:53.680 --> 00:05:57.319 Yeah, precisely. And BlackBerry's commitment to these principles really helped 132 00:05:57.360 --> 00:06:00.680 to make their devices popular in those sectors where data 133 00:06:00.680 --> 00:06:03.879 security was a top priority, like you know, government and finance. 134 00:06:04.199 --> 00:06:07.399 That makes sense. So even though blackberries aren't as common 135 00:06:07.439 --> 00:06:10.839 as they used to be, their security legacy is still relevant, 136 00:06:11.040 --> 00:06:14.360 especially as we think about how to protect our own data. Now. 137 00:06:14.600 --> 00:06:17.279 Besides delly lands and smartphones, we also have these other 138 00:06:17.319 --> 00:06:21.759 wireless technologies Bluetooth, NFC, infrared. They each have their own 139 00:06:21.759 --> 00:06:25.199 security things to consider. I'm curious about NFC actually because 140 00:06:25.240 --> 00:06:28.720 it's on almost every smartphone now, but I rarely see 141 00:06:28.759 --> 00:06:31.720 it being used for anything beyond you know, like simple 142 00:06:31.759 --> 00:06:33.639 things like contactless payments. 143 00:06:33.920 --> 00:06:37.319 Yeah, that's true. NFC really hasn't reached its full potential yet, 144 00:06:37.360 --> 00:06:40.079 even though it's got all this capability. It's a really 145 00:06:40.120 --> 00:06:44.759 powerful technology for secure close range communication, but its adoption 146 00:06:44.839 --> 00:06:45.920 has been kind of limited. 147 00:06:46.040 --> 00:06:47.639 So it's like, we have this super advanced tool, but 148 00:06:47.639 --> 00:06:50.480 we're only using it for these really basic tasks exactly. 149 00:06:50.680 --> 00:06:54.199 But we shouldn't dismiss NFC altogether because it's security features, 150 00:06:54.319 --> 00:06:57.040 especially it's limited range, you know, that makes it a 151 00:06:57.120 --> 00:07:00.759 really strong option for applications where data privacy is super important. 152 00:07:00.959 --> 00:07:04.240 That's interesting. So while NFC might not be as widely 153 00:07:04.319 --> 00:07:06.720 used as Bluetooth, it's got its strengths, especially when it 154 00:07:06.720 --> 00:07:10.439 comes to security. Now, speaking of Bluetooth, I use that 155 00:07:10.480 --> 00:07:12.639 all the time for my headphones and in my car, 156 00:07:14.319 --> 00:07:17.000 but I've also heard some things about its vulnerabilities. Are 157 00:07:17.079 --> 00:07:18.279 those concerns legitimate? 158 00:07:18.480 --> 00:07:20.920 Bluetooth is great, don't get me wrong. It's fantastic for 159 00:07:20.920 --> 00:07:24.199 connecting devices. But yeah, it's important to know that it 160 00:07:24.279 --> 00:07:27.600 does have some security limitations. You know, its range is 161 00:07:27.639 --> 00:07:30.720 wider than NFC, which means that the signals can be 162 00:07:30.759 --> 00:07:33.079 intercepted more easily if you're not taking precautions. 163 00:07:33.120 --> 00:07:35.800 Okay, that's a little concerning. So what can people do 164 00:07:35.959 --> 00:07:37.240 to reduce those risks? 165 00:07:37.399 --> 00:07:40.279 Some really simple things actually, like making sure your device's 166 00:07:40.319 --> 00:07:43.959 Bluetooth is set to non discoverable when you're not actively 167 00:07:44.040 --> 00:07:47.839 using it, using strong and unique pinons for pairing, and 168 00:07:48.000 --> 00:07:50.399 just being aware of your surroundings when you are connecting 169 00:07:50.399 --> 00:07:53.439 in public. Just doing those few things can significantly improve 170 00:07:53.480 --> 00:07:54.120 your security. 171 00:07:54.319 --> 00:07:57.920 Oh yeah, that's good advice. It seems like with any 172 00:07:57.920 --> 00:08:01.360 wireless technology, awareness and some basic cautions can go a 173 00:08:01.399 --> 00:08:03.680 long way. Before we move on, I wanted to get 174 00:08:03.720 --> 00:08:06.600 your thoughts on something that I thought was really important. 175 00:08:06.759 --> 00:08:08.959 One of our sources talked about how important it is 176 00:08:09.000 --> 00:08:11.879 to have an emergency plan for our digital lives. It's 177 00:08:11.879 --> 00:08:14.439 something that I think most of us don't really consider, 178 00:08:14.600 --> 00:08:16.439 but it could be crucial in a crisis. 179 00:08:16.879 --> 00:08:19.160 Oh, you are absolutely right to bring that up. We 180 00:08:19.199 --> 00:08:22.639 spend so much time thinking about how to prevent cybertex, 181 00:08:23.199 --> 00:08:25.399 but we often forget to think about what we do 182 00:08:25.600 --> 00:08:29.040 if our devices were lost or stolen or hacked. 183 00:08:29.360 --> 00:08:31.079 Yeah, I have to admit I haven't really thought about 184 00:08:31.079 --> 00:08:34.039 that myself. So where do we even begin with something 185 00:08:34.120 --> 00:08:34.480 like that. 186 00:08:34.840 --> 00:08:36.679 Well, I think a good place to start is to 187 00:08:36.759 --> 00:08:39.480 just think about those digital resources that you really rely on, 188 00:08:39.519 --> 00:08:42.799 so things like communication, banking, work, files, your social connections, 189 00:08:43.159 --> 00:08:45.759 and then just brainstorm some strategies for how you would 190 00:08:45.759 --> 00:08:47.759 access those or recover them if you had to in 191 00:08:47.759 --> 00:08:48.519 an emergency. 192 00:08:48.720 --> 00:08:51.279 So it's like identifying those crucial parts of my digital 193 00:08:51.320 --> 00:08:55.039 life and figuring out how to stay afloat if they're 194 00:08:55.039 --> 00:08:56.720 suddenly cut off exactly. 195 00:08:57.080 --> 00:09:00.559 Think about things like backing up your data regularly, knowing 196 00:09:00.600 --> 00:09:03.159 how to remotely wipe your devices if they get lost, 197 00:09:03.639 --> 00:09:07.519 having a communication plan that doesn't completely rely on your smartphone. 198 00:09:07.840 --> 00:09:10.240 This has given me a lot to think about. It 199 00:09:10.320 --> 00:09:13.440 sounds like preparing for a digital emergency is just as 200 00:09:13.480 --> 00:09:15.960 important at protecting ourselves from those cyber attacks in the 201 00:09:16.000 --> 00:09:20.000 first place. Well, this has been a fascinating discussion so far. 202 00:09:20.080 --> 00:09:22.960 We've covered a lot of ground already, from w lands 203 00:09:23.000 --> 00:09:27.559 to smartphones, to NFC and Bluetooth and even emergency preparedness, 204 00:09:28.000 --> 00:09:30.519 but there's still a lot more to discuss. In the 205 00:09:30.559 --> 00:09:32.559 next part of our jep dive, we'll dig deeper into 206 00:09:32.559 --> 00:09:35.759 those specific security measures and the best practices to keep 207 00:09:35.799 --> 00:09:39.159 you safe in this ever evolving wireless world. Welcome back. 208 00:09:39.879 --> 00:09:41.919 You know, after that last conversation, I feel like I 209 00:09:41.960 --> 00:09:44.200 learned a lot. It's amazing how much we all rely 210 00:09:44.320 --> 00:09:47.039 on wireless technology, but we don't really stop to think 211 00:09:47.039 --> 00:09:48.200 about the security risks. 212 00:09:48.360 --> 00:09:50.799 Yeah, that's true, but that's what's so great about learning 213 00:09:50.799 --> 00:09:53.120 more about it, right, It helps us make smarter choices 214 00:09:53.159 --> 00:09:55.320 and you know, take more control of our digital lives. 215 00:09:55.600 --> 00:09:58.480 Speaking of taking control, let's talk about some of the 216 00:09:58.519 --> 00:10:02.279 practical steps that we can take actually improve our wireless security. 217 00:10:02.600 --> 00:10:04.720 I'm ready to put all this knowledge into action. 218 00:10:05.519 --> 00:10:08.159 That's the spirit, and actually a lot of the most 219 00:10:08.159 --> 00:10:11.559 effective things you can do, are pretty simple to implement. 220 00:10:11.799 --> 00:10:15.759 Okay, I'm all yours. Let's hear it. Where do we start. 221 00:10:16.159 --> 00:10:19.960 Let's start with the most basic thing, strong passwords. It 222 00:10:20.039 --> 00:10:22.679 might seem obvious, but you'd be surprised how many people 223 00:10:22.720 --> 00:10:25.919 still use weak passwords or passwords that are really easy 224 00:10:25.960 --> 00:10:26.399 to guess. 225 00:10:26.600 --> 00:10:28.799 Okay, I'll admit I'm guilty of that. Sometimes I'll use 226 00:10:28.840 --> 00:10:31.720 the same password for multiple accounts just because it's easier 227 00:10:31.759 --> 00:10:32.240 to remember. 228 00:10:32.399 --> 00:10:34.879 I get it, it's tempting, But using the same password 229 00:10:34.960 --> 00:10:37.200 for everything is a huge risk. It's kind of like 230 00:10:37.320 --> 00:10:39.559 using the same key for your house, your car, and 231 00:10:39.600 --> 00:10:42.360 your office. If someone gets hold of that key, they've 232 00:10:42.399 --> 00:10:43.679 got access to everything. 233 00:10:43.879 --> 00:10:46.919 Okay, point take, And so what makes a password strong? Anyway? 234 00:10:47.159 --> 00:10:50.399 A strong password should be at least twelve characters long, 235 00:10:50.480 --> 00:10:52.360 and you want to use a mix of uppercase and 236 00:10:52.360 --> 00:10:56.159 lowercase letters, numbers, and symbols. Oh, and try to avoid 237 00:10:56.240 --> 00:11:00.360 using any personal information like your birthday or your pets name, 238 00:11:00.840 --> 00:11:02.799 you know, stuff that people could easily find out. 239 00:11:02.919 --> 00:11:06.440 Got it longer, more complex, and less personal. But how 240 00:11:06.480 --> 00:11:09.120 am I supposed to remember all these different passwords? It 241 00:11:09.120 --> 00:11:10.919 feels like I've got a million things to keep track 242 00:11:10.960 --> 00:11:11.480 of already. 243 00:11:11.679 --> 00:11:15.879 That's where a password manager comes in. They're seriously life savers. 244 00:11:16.320 --> 00:11:20.440 Password managers generate and store those strong, unique passwords for 245 00:11:20.559 --> 00:11:23.240 all your accounts, so you only need to remember one 246 00:11:23.559 --> 00:11:26.559 master password. It's like having this digital vault for all 247 00:11:26.559 --> 00:11:27.120 your keys. 248 00:11:27.360 --> 00:11:30.240 That sounds amazing. I've heard of those, but I always 249 00:11:30.240 --> 00:11:31.759 thought they were more for techy people. 250 00:11:32.080 --> 00:11:34.679 Not at all. There are tons of password managers out 251 00:11:34.720 --> 00:11:37.200 there that are really easy to use. Anyone can set 252 00:11:37.240 --> 00:11:39.720 them up in just a few minutes, and honestly, they're 253 00:11:39.799 --> 00:11:42.399 essential for anyone who uses the Internet. It doesn't matter 254 00:11:42.399 --> 00:11:43.399 how tech savvy you are. 255 00:11:43.600 --> 00:11:46.360 Okay, you've convinced me. Password manager added to the list. 256 00:11:47.679 --> 00:11:48.440 What else is there? 257 00:11:48.559 --> 00:11:52.440 Another super important one? Keep your software updated. Software updates 258 00:11:52.519 --> 00:11:56.799 usually include security patches that fix vulnerabilities that hackers could exploit. 259 00:11:57.080 --> 00:11:59.639 It's like patching up holes in your digital fence before 260 00:11:59.639 --> 00:12:00.639 the wool can get in. 261 00:12:00.759 --> 00:12:03.720 I'm usually pretty good about updating my phone, but I'll 262 00:12:03.720 --> 00:12:06.600 admit I tend to put off computer updates. They always 263 00:12:06.600 --> 00:12:08.120 seem to pop up at the worst times. 264 00:12:08.240 --> 00:12:10.919 Yeah, I know those update notifications can be annoying, but 265 00:12:11.039 --> 00:12:14.480 trust me, they're there for a reason. Your front line 266 00:12:14.480 --> 00:12:17.360 of defense against malware and other threats, and putting them 267 00:12:17.399 --> 00:12:18.840 off just makes you more vulnerable. 268 00:12:18.919 --> 00:12:23.919 All right, all right, you win. No more procrastinating updates. Check. Now, 269 00:12:23.919 --> 00:12:27.080 what about firewalls? Are those still important now that we 270 00:12:27.120 --> 00:12:29.279 have smartphones and everything's in the cloud. 271 00:12:29.519 --> 00:12:33.759 Definitely, firewalls are still a crucial part of any security strategy. 272 00:12:34.080 --> 00:12:36.120 Think of them like your digital bouncer. They're there to 273 00:12:36.200 --> 00:12:37.360 keep the riff raff out. 274 00:12:37.559 --> 00:12:40.519 So they basically act as a barrier between my devices 275 00:12:40.519 --> 00:12:44.639 and the outside world, locking anything suspicious from getting in exactly. 276 00:12:44.679 --> 00:12:47.440 And the good news is most operating systems actually come 277 00:12:47.480 --> 00:12:50.120 with built in firewalls, but you can also get third 278 00:12:50.120 --> 00:12:53.120 party ones for even more protection, especially if you're working 279 00:12:53.159 --> 00:12:54.399 with sensitive information. 280 00:12:54.679 --> 00:12:57.840 Okay, so firewalls are a must have, but all this 281 00:12:57.919 --> 00:13:00.759 talk about potential threats is making me a lay little paranoid. 282 00:13:00.919 --> 00:13:02.919 A little bit of paranoia isn't a bad thing when 283 00:13:02.919 --> 00:13:05.799 it comes to cybersecurity. It's not about living in fear. 284 00:13:05.840 --> 00:13:09.399 It's about being aware and taking steps to protect yourself. 285 00:13:09.639 --> 00:13:12.480 That makes sense. It's like being aware of your surroundings 286 00:13:12.519 --> 00:13:15.039 when you're walking alone at night. You don't have to 287 00:13:15.080 --> 00:13:17.440 assume that everyone's out to get you, but you're still 288 00:13:17.480 --> 00:13:20.360 paying attention and taking precautions just in case. 289 00:13:20.480 --> 00:13:22.799 That's a great analogy. And you know, speaking of awareness, 290 00:13:22.879 --> 00:13:26.360 there's another really important aspect of wireless security that we 291 00:13:26.440 --> 00:13:28.240 need to talk about. Social engineering. 292 00:13:28.399 --> 00:13:32.639 Social engineering. What's that like trying to hack someone's social media? 293 00:13:33.399 --> 00:13:37.000 Not exactly, it's a broader term that basically means using 294 00:13:37.039 --> 00:13:40.399 tricks and deception to manipulate people into giving up sensitive 295 00:13:40.399 --> 00:13:44.240 information or getting them to do things that compromise their security. 296 00:13:44.600 --> 00:13:47.039 Oh so, like those phishing emails that try to trick 297 00:13:47.080 --> 00:13:47.799 you into clicking on. 298 00:13:47.799 --> 00:13:52.919 A bad link exactly. Phishing is a classic social engineering tactic. 299 00:13:53.240 --> 00:13:55.639 Hackers will send emails that look like they're from a 300 00:13:55.720 --> 00:13:59.320 legitimate source like your bank or an online store you use, 301 00:14:00.039 --> 00:14:01.600 and they try to get you to give them your 302 00:14:01.600 --> 00:14:04.200 login details or other personal information. 303 00:14:04.600 --> 00:14:07.320 Yeah, I've seen those. They can be really convincing. What 304 00:14:07.360 --> 00:14:08.759 else should people be on the lookout for? 305 00:14:09.000 --> 00:14:12.559 Social engineering can come in all sorts of forms, phone calls, 306 00:14:12.679 --> 00:14:16.240 text messages, even social media posts. The important thing is 307 00:14:16.240 --> 00:14:18.879 to be skeptical of anyone who asks you for personal 308 00:14:18.879 --> 00:14:22.559 information out of the blue. Always verify the sender's identity 309 00:14:22.600 --> 00:14:25.480 before you click on links or open attachments, and if 310 00:14:25.480 --> 00:14:27.559 something seems too good to be true, it probably is. 311 00:14:27.720 --> 00:14:29.480 Wow, it sounds like we have to be on guard 312 00:14:29.519 --> 00:14:30.000 all the time. 313 00:14:30.279 --> 00:14:33.360 Not really. It's more about developing that critical thinking mindset 314 00:14:33.519 --> 00:14:36.519 and questioning things that seem a bit off. Think before 315 00:14:36.519 --> 00:14:39.320 you click, and if something feels wrong, trust your gut. 316 00:14:39.399 --> 00:14:43.960 Okay, that's reassuring. So strong passwords, software updates, firewalls, and 317 00:14:44.200 --> 00:14:47.639 watching out for social engineering. Those are our main defenses 318 00:14:47.720 --> 00:14:48.960 against wireless threats. 319 00:14:49.279 --> 00:14:52.320 You got it. Those are the basic building blocks for 320 00:14:52.320 --> 00:14:56.919 staying safe online. And remember, it's not about achieving perfect security, 321 00:14:56.960 --> 00:15:00.320 because that's pretty much impossible. It's about reducing your risk 322 00:15:00.399 --> 00:15:02.720 and making yourself a less appealing target. 323 00:15:02.960 --> 00:15:06.279 Right. It's like making your house less attractive to burglars. Yeah, 324 00:15:06.320 --> 00:15:08.720 you can't stop every single break in, but you can 325 00:15:08.759 --> 00:15:10.600 make it a lot harder for them, and hopefully they'll 326 00:15:10.639 --> 00:15:12.039 just move on to an easier target. 327 00:15:12.240 --> 00:15:14.720 Exactly. And the best part is that when you take 328 00:15:14.759 --> 00:15:17.759 these security measures, it doesn't just protect you, it also 329 00:15:17.840 --> 00:15:20.279 protects the people and networks that you connect with. 330 00:15:20.480 --> 00:15:22.519 That's a good point. It's like a team effort to 331 00:15:22.519 --> 00:15:25.399 make the whole wireless world a bit safer. This has 332 00:15:25.440 --> 00:15:28.120 been super helpful. I feel a lot more confident about 333 00:15:28.120 --> 00:15:31.200 taking control of my own wireless security. But I'm sure 334 00:15:31.200 --> 00:15:34.039 there are some specific situations where it helps to have 335 00:15:34.080 --> 00:15:37.240 some expert advice. Let's move on to the final part 336 00:15:37.240 --> 00:15:38.840 of our deep dive and we can talk about those 337 00:15:38.879 --> 00:15:41.000 situations and how we can apply all the stuff we've 338 00:15:41.080 --> 00:15:43.080 learned to our everyday lives. 339 00:15:43.440 --> 00:15:46.039 All right, welcome back to our wireless security deep dive. 340 00:15:46.559 --> 00:15:48.720 We've covered a lot of ground, haven't we. Different types 341 00:15:48.759 --> 00:15:52.480 of networks or risks involved, even how create like a 342 00:15:52.519 --> 00:15:55.799 digital emergency plan. But now let's get to the practical stuff. 343 00:15:55.919 --> 00:15:58.080 How can we actually use all of this in our 344 00:15:58.159 --> 00:15:58.799 daily lives. 345 00:15:59.039 --> 00:16:00.960 That's what it's all about. Right, Let's walk through a 346 00:16:00.960 --> 00:16:03.360 few common situations and see how we can apply these 347 00:16:03.360 --> 00:16:06.840 concepts and make some smarter choices about using wireless technology. 348 00:16:07.200 --> 00:16:09.279 Sounds good, So let's say I'm at a coffee shop 349 00:16:09.279 --> 00:16:11.159 trying to get some work done and I see that 350 00:16:11.360 --> 00:16:13.559 free Wi Fi sign. What do I do? 351 00:16:13.720 --> 00:16:16.840 Well? First, take a breath, resist that urge to just 352 00:16:17.039 --> 00:16:20.799 connect automatically. Free Wi Fi, especially in public places, can 353 00:16:20.840 --> 00:16:23.559 be pretty risky. So should I just use my data plan? 354 00:16:23.639 --> 00:16:25.639 Then even if it cost me an arm and a leg. 355 00:16:25.919 --> 00:16:28.480 Well, that's probably the safest option, especially if you're dealing 356 00:16:28.480 --> 00:16:31.559 with anything sensitive. But let's be real, sometimes you just 357 00:16:31.559 --> 00:16:33.559 got to use that Wi Fi, right, whether it's for 358 00:16:33.600 --> 00:16:35.679 a quick email or you know, you need to get 359 00:16:35.679 --> 00:16:36.639 some work done. 360 00:16:36.360 --> 00:16:39.480 Exactly, So what can I do to at least minimize 361 00:16:39.480 --> 00:16:43.000 the risk when I absolutely have to use public Wi Fi? 362 00:16:43.240 --> 00:16:45.200 All right? First things first, make sure you're connecting to 363 00:16:45.240 --> 00:16:48.120 the right network. Don't just blindly connect to anything that 364 00:16:48.159 --> 00:16:50.960 pops up. Double check the name of the coffee shop's 365 00:16:51.000 --> 00:16:53.840 Wi Fi with someone who works there. You'd be surprised 366 00:16:53.879 --> 00:16:55.480 how easy it is for someone to set up a 367 00:16:55.480 --> 00:16:58.080 fake network with a similar name to try and trick people. 368 00:16:58.399 --> 00:17:01.120 Oh wow, okay, so confirm the network name. Got it? 369 00:17:01.240 --> 00:17:02.240 Got it? What else? 370 00:17:02.399 --> 00:17:05.440 Remember we talked about VPNs. This is where they're super useful. 371 00:17:05.559 --> 00:17:08.920 Ah, right, the virtual private network thing that creates that 372 00:17:08.960 --> 00:17:11.880 secure tunnel. But is it really necessary if I'm just 373 00:17:12.079 --> 00:17:15.599 you know, checking email or browsing websites? 374 00:17:15.720 --> 00:17:18.440 Honestly, it's always better to be safe than sorry, right. 375 00:17:18.880 --> 00:17:21.319 A VPN encrypts all of your Internet traffic, so even 376 00:17:21.359 --> 00:17:24.000 if someone's trying to snoop. They can't see what you're doing. 377 00:17:23.920 --> 00:17:26.359 So they just see a bunch of gibberish basically pretty much. 378 00:17:26.599 --> 00:17:28.400 They might be able to see that you're connected to 379 00:17:28.440 --> 00:17:30.720 something that they won't be able to read the actual 380 00:17:30.799 --> 00:17:32.759 data that you're sending and receiving. 381 00:17:32.880 --> 00:17:35.000 Okay. VPNs are officially at the top of my to 382 00:17:35.000 --> 00:17:39.680 do list. All right. Next scenario, I'm leaving the coffee shop, 383 00:17:39.720 --> 00:17:42.440 getting in my car, and I connect my phone to 384 00:17:42.519 --> 00:17:47.480 the Bluetooth to play some music. Hmm, what should I 385 00:17:47.519 --> 00:17:48.440 be thinking about there? 386 00:17:48.799 --> 00:17:50.960 Well, with Bluetooth, the most important thing is to make 387 00:17:51.000 --> 00:17:54.400 sure that your device's Bluetooth is set to non discoverable 388 00:17:54.839 --> 00:17:56.640 when you're not actually pairing it with something. 389 00:17:56.759 --> 00:17:59.000 So kind of like locking your car doors. Yeah, you 390 00:17:59.000 --> 00:18:00.880 don't want to leave it wide open for anyone to 391 00:18:01.000 --> 00:18:02.319 just get in exactly. 392 00:18:02.680 --> 00:18:05.559 And when you are pairing a device, make sure it's 393 00:18:05.680 --> 00:18:09.599 the right one. Hackers can create fake Bluetooth devices that 394 00:18:09.680 --> 00:18:12.279 have names that sound like the real deal, hoping you'll 395 00:18:12.279 --> 00:18:13.240 accidentally connect. 396 00:18:13.400 --> 00:18:16.759 Man. That's sneaky, okay, so double check the device name 397 00:18:16.799 --> 00:18:20.079 before pairing. Anything else to watch out for with Bluetooth. 398 00:18:19.799 --> 00:18:23.160 Yeah, just be aware of your surroundings. You know, in 399 00:18:23.240 --> 00:18:26.160 crowded places or where there are lots of electronics, there's 400 00:18:26.160 --> 00:18:29.960 a higher chance of interference or potential eavesdropping. And like 401 00:18:30.000 --> 00:18:32.799
