1 00:00:00,120 --> 00:00:01,230 In this section of the course, 2 00:00:01,230 --> 00:00:03,570 we're going to talk about security techniques. 3 00:00:03,570 --> 00:00:04,590 In the digital age, 4 00:00:04,590 --> 00:00:06,480 the importance of robust security techniques 5 00:00:06,480 --> 00:00:08,100 cannot be overstated. 6 00:00:08,100 --> 00:00:10,350 As we are increasingly relying on technology 7 00:00:10,350 --> 00:00:11,880 for a plethora of tasks, 8 00:00:11,880 --> 00:00:13,950 the need to protect our systems and data 9 00:00:13,950 --> 00:00:16,379 from potential threats have become paramount. 10 00:00:16,379 --> 00:00:18,440 This section delves into the diverse world 11 00:00:18,440 --> 00:00:19,620 of security techniques, 12 00:00:19,620 --> 00:00:21,780 exploring the various strategies, tools, 13 00:00:21,780 --> 00:00:22,950 and methodologies employed 14 00:00:22,950 --> 00:00:25,320 to protect different digital assets. 15 00:00:25,320 --> 00:00:28,110 From traditional firewalls and antivirus software 16 00:00:28,110 --> 00:00:29,250 to more advanced techniques, 17 00:00:29,250 --> 00:00:31,770 such as biometric authentication, encryption, 18 00:00:31,770 --> 00:00:33,330 and intrusive detection systems, 19 00:00:33,330 --> 00:00:35,250 we will provide a comprehensive overview 20 00:00:35,250 --> 00:00:37,320 of the landscape of security techniques. 21 00:00:37,320 --> 00:00:39,450 We will also discuss the evolving nature 22 00:00:39,450 --> 00:00:40,283 of these techniques 23 00:00:40,283 --> 00:00:43,620 in response to the changing landscape of cyber threats. 24 00:00:43,620 --> 00:00:45,570 Whether you're a seasoned IT professional 25 00:00:45,570 --> 00:00:47,100 or a novice in the field, 26 00:00:47,100 --> 00:00:49,680 this section will equip you with the knowledge that you need 27 00:00:49,680 --> 00:00:53,160 to understand and implement effective security measures. 28 00:00:53,160 --> 00:00:54,900 So in this section of the course, 29 00:00:54,900 --> 00:00:57,330 we'll be focusing solely on Domain 4, 30 00:00:57,330 --> 00:01:00,750 specifically objectives 4.1 and 4.5. 31 00:01:00,750 --> 00:01:03,180 Objective 4.1 states that, given a scenario, 32 00:01:03,180 --> 00:01:05,730 you must be able to apply common security techniques 33 00:01:05,730 --> 00:01:07,680 to computing resources. 34 00:01:07,680 --> 00:01:10,200 Objective 4.5 states that, given a scenario, 35 00:01:10,200 --> 00:01:13,290 you must be able to modify enterprise capabilities 36 00:01:13,290 --> 00:01:15,240 to enhance security. 37 00:01:15,240 --> 00:01:18,840 First, we'll go over wireless infrastructure security. 38 00:01:18,840 --> 00:01:21,120 Wireless networks have become an integral part 39 00:01:21,120 --> 00:01:22,140 of our daily lives. 40 00:01:22,140 --> 00:01:23,880 From personal use in our homes 41 00:01:23,880 --> 00:01:26,280 to large-scale operations and businesses, 42 00:01:26,280 --> 00:01:28,800 these networks facilitate seamless communication 43 00:01:28,800 --> 00:01:30,120 and data exchange. 44 00:01:30,120 --> 00:01:32,610 However, the convenience of wireless connectivity 45 00:01:32,610 --> 00:01:35,490 also brings with it a host of security challenges. 46 00:01:35,490 --> 00:01:37,620 Next, we're going to jump into discussion 47 00:01:37,620 --> 00:01:39,210 of wireless security setting. 48 00:01:39,210 --> 00:01:41,670 We're going to go over WPA3, 49 00:01:41,670 --> 00:01:44,670 AAA, RADIUS, cryptographic protocols, 50 00:01:44,670 --> 00:01:46,710 and authentication protocols. 51 00:01:46,710 --> 00:01:49,350 Then we're going to talk about application security, 52 00:01:49,350 --> 00:01:52,230 including input validation, secure cookies, 53 00:01:52,230 --> 00:01:55,020 static code analysis, dynamic code analysis, 54 00:01:55,020 --> 00:01:57,570 code signing and sandboxing. 55 00:01:57,570 --> 00:01:59,310 After that, we're going to discuss 56 00:01:59,310 --> 00:02:01,890 network access control, or NAC. 57 00:02:01,890 --> 00:02:03,360 NAC is a security solution 58 00:02:03,360 --> 00:02:06,870 that enforces policies on devices and users in the network. 59 00:02:06,870 --> 00:02:09,210 It is designed to protect networks from potential threats 60 00:02:09,210 --> 00:02:11,910 by restricting the availability of network resources 61 00:02:11,910 --> 00:02:13,743 to endpoint devices and users. 62 00:02:14,580 --> 00:02:17,760 Next, we're going to discuss web and DNS filtering. 63 00:02:17,760 --> 00:02:20,730 In this lesson, we'll cover agent-based web filters, 64 00:02:20,730 --> 00:02:23,130 centralized proxies, URL scanning, 65 00:02:23,130 --> 00:02:27,180 content categorization, block rules and reputation. 66 00:02:27,180 --> 00:02:29,580 Then we'll take a look at email security, 67 00:02:29,580 --> 00:02:31,380 and we'll talk about some of the important protocols, 68 00:02:31,380 --> 00:02:36,360 like DMARC, DKIM, SPF, and gateway protocol, 69 00:02:36,360 --> 00:02:39,240 as well as covering some spam filtering techniques. 70 00:02:39,240 --> 00:02:42,630 After that, we'll dive into endpoint detection and response, 71 00:02:42,630 --> 00:02:44,490 or EDR. 72 00:02:44,490 --> 00:02:47,760 EDR is a cybersecurity technology that continuously monitors 73 00:02:47,760 --> 00:02:49,740 and collects data from endpoint devices, 74 00:02:49,740 --> 00:02:51,960 like computers, tablets, or smartphones, 75 00:02:51,960 --> 00:02:54,120 in order to identify, investigate, 76 00:02:54,120 --> 00:02:57,120 and prevent potential cybersecurity threats. 77 00:02:57,120 --> 00:03:00,330 Next, we're going to cover user behavior analytics. 78 00:03:00,330 --> 00:03:02,490 User behavior analytics is a process 79 00:03:02,490 --> 00:03:05,100 that leverages machine learning data analytics 80 00:03:05,100 --> 00:03:06,600 and user behavior patterns 81 00:03:06,600 --> 00:03:09,180 to identify potentially harmful activities 82 00:03:09,180 --> 00:03:10,980 within a system or network. 83 00:03:10,980 --> 00:03:13,800 By establishing a baseline of normal behaviors, 84 00:03:13,800 --> 00:03:16,983 UBA systems can detect anomalies or deviations. 85 00:03:17,910 --> 00:03:20,880 Then we'll cover selecting secure protocols. 86 00:03:20,880 --> 00:03:23,400 This includes protocol selection, course selection, 87 00:03:23,400 --> 00:03:25,980 and transport method selections. 88 00:03:25,980 --> 00:03:28,800 And finally, we'll take a short quiz to see what you learned 89 00:03:28,800 --> 00:03:30,030 during this section of the course, 90 00:03:30,030 --> 00:03:32,220 and review each one of those quiz questions 91 00:03:32,220 --> 00:03:33,810 to fully ensure that you can explain 92 00:03:33,810 --> 00:03:36,060 why the right answers were right. 93 00:03:36,060 --> 00:03:37,830 So let's jump into the coverage 94 00:03:37,830 --> 00:03:39,930 of various security techniques that we can utilize 95 00:03:39,930 --> 00:03:41,553 in this section of the course.
