WEBVTT 1 00:00:00.090 --> 00:00:01.290 In this lesson, 2 00:00:01.290 --> 00:00:05.250 we will learn about dynamic security controls. 3 00:00:05.250 --> 00:00:09.480 Dynamic security controls are adaptive measures 4 00:00:09.480 --> 00:00:12.750 that automatically adjust security settings 5 00:00:12.750 --> 00:00:17.610 in response to changing conditions or detected threats 6 00:00:17.610 --> 00:00:21.270 in order to maintain continuous protection. 7 00:00:21.270 --> 00:00:26.070 Dynamic security controls include event-based triggers 8 00:00:26.070 --> 00:00:27.780 and auto-containment, 9 00:00:27.780 --> 00:00:31.470 where event-based triggers are specific conditions 10 00:00:31.470 --> 00:00:35.940 or incidents such as a detected malware signature 11 00:00:35.940 --> 00:00:38.850 or an unusual network pattern. 12 00:00:38.850 --> 00:00:41.880 And auto-containment is a process 13 00:00:41.880 --> 00:00:44.700 where potentially harmful activities 14 00:00:44.700 --> 00:00:48.900 or suspicious entities are automatically isolated 15 00:00:48.900 --> 00:00:51.120 from the rest of the network 16 00:00:51.120 --> 00:00:54.390 to prevent the spread of infection. 17 00:00:54.390 --> 00:00:57.540 Let's learn more about event-based triggers 18 00:00:57.540 --> 00:00:59.850 and auto-containment. 19 00:00:59.850 --> 00:01:03.330 First, we have event-based triggers. 20 00:01:03.330 --> 00:01:06.540 Event-based triggers act as the alarm bells 21 00:01:06.540 --> 00:01:08.250 of a security system. 22 00:01:08.250 --> 00:01:12.150 To better understand this, imagine a smart home 23 00:01:12.150 --> 00:01:15.990 where certain triggers, like the sound of breaking glass 24 00:01:15.990 --> 00:01:20.190 or unexpected motion, immediately alert the homeowner 25 00:01:20.190 --> 00:01:24.960 of a malicious event or automatically lock certain doors. 26 00:01:24.960 --> 00:01:26.640 In digital security, 27 00:01:26.640 --> 00:01:30.930 event-based triggers can provide the same type of awareness 28 00:01:30.930 --> 00:01:33.240 and monitor specific conditions 29 00:01:33.240 --> 00:01:38.070 or indicators like a new malware signature detected 30 00:01:38.070 --> 00:01:41.100 or an unexpected network anomaly. 31 00:01:41.100 --> 00:01:44.370 Each of these could signal a potential threat. 32 00:01:44.370 --> 00:01:46.710 When these conditions are detected, 33 00:01:46.710 --> 00:01:49.980 event-based triggers automatically initiate 34 00:01:49.980 --> 00:01:53.520 security responses, quickly addressing the threats 35 00:01:53.520 --> 00:01:55.800 before they can cause harm. 36 00:01:55.800 --> 00:01:58.800 So by monitoring network activity 37 00:01:58.800 --> 00:02:02.100 and analyzing behavior in real time, 38 00:02:02.100 --> 00:02:05.220 event-based triggers help security systems 39 00:02:05.220 --> 00:02:08.100 remain alert and proactive. 40 00:02:08.100 --> 00:02:12.090 But what can event-based triggers detect? 41 00:02:12.090 --> 00:02:14.820 Well, event-based triggers can detect 42 00:02:14.820 --> 00:02:18.000 anything from unauthorized login attempts 43 00:02:18.000 --> 00:02:20.370 to unusual data transfers, 44 00:02:20.370 --> 00:02:23.790 which are often signs of malicious activity. 45 00:02:23.790 --> 00:02:27.450 Tools like intrusion detection systems or IDS 46 00:02:27.450 --> 00:02:30.510 and security information and event management 47 00:02:30.510 --> 00:02:34.380 or SIEM platforms are commonly used to monitor 48 00:02:34.380 --> 00:02:36.780 and alert on such activities, 49 00:02:36.780 --> 00:02:41.160 providing real time insights into network anomalies. 50 00:02:41.160 --> 00:02:45.690 For example, if a user's login location changes 51 00:02:45.690 --> 00:02:48.870 from one country to another within minutes, 52 00:02:48.870 --> 00:02:52.560 this could be an indication of a compromised account. 53 00:02:52.560 --> 00:02:56.580 So this sudden change in location would activate 54 00:02:56.580 --> 00:03:00.330 an event-based trigger initiating a series 55 00:03:00.330 --> 00:03:05.160 of security measures like multifactor re-authentication, 56 00:03:05.160 --> 00:03:08.100 or even temporarily blocking access 57 00:03:08.100 --> 00:03:11.160 until the user's identity is confirmed. 58 00:03:11.160 --> 00:03:15.390 Through these types of event-based automated responses, 59 00:03:15.390 --> 00:03:18.570 triggers help prevent unauthorized access 60 00:03:18.570 --> 00:03:22.800 and protect sensitive information by responding instantly 61 00:03:22.800 --> 00:03:25.590 to suspicious and anomalous events. 62 00:03:25.590 --> 00:03:29.100 Another useful aspect of event-based triggers 63 00:03:29.100 --> 00:03:33.000 is their ability to adapt to new threat intelligence. 64 00:03:33.000 --> 00:03:36.840 For instance, as new types of malware are discovered, 65 00:03:36.840 --> 00:03:39.510 the security infrastructure can update 66 00:03:39.510 --> 00:03:42.000 its malware signature database. 67 00:03:42.000 --> 00:03:45.210 This enables it to recognize new threats 68 00:03:45.210 --> 00:03:48.180 as soon as they appear in the network, 69 00:03:48.180 --> 00:03:51.210 reducing the time it takes to recognize 70 00:03:51.210 --> 00:03:54.060 and respond to new attack methods. 71 00:03:54.060 --> 00:03:58.260 Essentially, event-based triggers allow security measures 72 00:03:58.260 --> 00:04:02.100 to evolve in real time, responding dynamically 73 00:04:02.100 --> 00:04:04.530 to the latest security threats. 74 00:04:04.530 --> 00:04:07.860 In a practical setting, event-based triggers 75 00:04:07.860 --> 00:04:10.200 offer continuous protection 76 00:04:10.200 --> 00:04:13.680 without relying solely on human intervention. 77 00:04:13.680 --> 00:04:17.160 Many times by automating initial responses 78 00:04:17.160 --> 00:04:18.930 to trigger events. 79 00:04:18.930 --> 00:04:22.410 Automation tools like orchestration platforms 80 00:04:22.410 --> 00:04:25.350 can further streamline these responses, 81 00:04:25.350 --> 00:04:27.360 enabling security teams 82 00:04:27.360 --> 00:04:29.820 to establish automated workflows 83 00:04:29.820 --> 00:04:32.850 that activate when certain triggers are met. 84 00:04:32.850 --> 00:04:35.940 This ability to continuously monitor 85 00:04:35.940 --> 00:04:40.260 and automatically respond, frees up valuable time 86 00:04:40.260 --> 00:04:44.310 for security personnel to focus on decision-making 87 00:04:44.310 --> 00:04:46.470 rather than being overwhelmed 88 00:04:46.470 --> 00:04:49.380 by routine alert investigation. 89 00:04:49.380 --> 00:04:53.040 So by taking swift, automatic action 90 00:04:53.040 --> 00:04:55.290 when specific conditions are met, 91 00:04:55.290 --> 00:04:59.460 event-based triggers serve as a frontline defense 92 00:04:59.460 --> 00:05:01.620 against potential threats. 93 00:05:01.620 --> 00:05:04.530 Second, we have auto-containment. 94 00:05:04.530 --> 00:05:07.860 Auto-containment is a security strategy 95 00:05:07.860 --> 00:05:11.520 that involves isolating potentially harmful entities 96 00:05:11.520 --> 00:05:13.530 from the rest of the network. 97 00:05:13.530 --> 00:05:17.490 Think of auto-containment as a hospital quarantine. 98 00:05:17.490 --> 00:05:21.180 If someone shows signs of a contagious illness, 99 00:05:21.180 --> 00:05:23.400 they're placed in a separate room 100 00:05:23.400 --> 00:05:27.480 to prevent the spread of that illness to others. 101 00:05:27.480 --> 00:05:30.870 In the same way when an activity or file 102 00:05:30.870 --> 00:05:33.750 is deemed suspicious within a network, 103 00:05:33.750 --> 00:05:37.590 auto-containment isolates it, preventing the activity 104 00:05:37.590 --> 00:05:42.030 or file from interacting with other network components. 105 00:05:42.030 --> 00:05:44.340 This allows security teams 106 00:05:44.340 --> 00:05:47.730 to analyze the potential threat without risking 107 00:05:47.730 --> 00:05:51.570 network-wide infection or data compromise. 108 00:05:51.570 --> 00:05:54.570 For example, consider a scenario 109 00:05:54.570 --> 00:05:57.690 where a device begins behaving abnormally 110 00:05:57.690 --> 00:06:00.120 by sending large amounts of data 111 00:06:00.120 --> 00:06:03.120 to an unknown external location. 112 00:06:03.120 --> 00:06:06.960 Auto-containment would immediately isolate that device 113 00:06:06.960 --> 00:06:08.940 from the rest of the network, 114 00:06:08.940 --> 00:06:12.660 limiting its communication with other devices. 115 00:06:12.660 --> 00:06:15.630 This prevents any potential malware 116 00:06:15.630 --> 00:06:19.380 or unauthorized access from spreading further. 117 00:06:19.380 --> 00:06:23.370 While in isolation, the device can still be examined 118 00:06:23.370 --> 00:06:26.970 by security teams to determine the root cause 119 00:06:26.970 --> 00:06:29.130 of its abnormal behavior. 120 00:06:29.130 --> 00:06:32.430 If the issue is found to be a false positive, 121 00:06:32.430 --> 00:06:35.550 the device can be restored to production, 122 00:06:35.550 --> 00:06:37.800 otherwise further containment 123 00:06:37.800 --> 00:06:41.100 or remediation measures can be implemented. 124 00:06:41.100 --> 00:06:45.420 Finally, auto-containment is particularly valuable 125 00:06:45.420 --> 00:06:48.720 in environments where network traffic is high. 126 00:06:48.720 --> 00:06:52.590 This is because it enables rapid isolation 127 00:06:52.590 --> 00:06:55.620 without affecting production operations. 128 00:06:55.620 --> 00:06:58.740 For instance, a large organization 129 00:06:58.740 --> 00:07:02.070 may have hundreds of devices connected at once, 130 00:07:02.070 --> 00:07:06.450 making it challenging to manually respond to each threat. 131 00:07:06.450 --> 00:07:09.510 With auto-containment, suspicious entities 132 00:07:09.510 --> 00:07:13.440 are automatically isolated without interrupting 133 00:07:13.440 --> 00:07:16.650 the productivity of other network users. 134 00:07:16.650 --> 00:07:19.890 This quick and efficient auto-containment 135 00:07:19.890 --> 00:07:23.760 ensures potential threats are handled efficiently 136 00:07:23.760 --> 00:07:28.290 while minimizing any impact on business operations, 137 00:07:28.290 --> 00:07:32.430 keeping both security and productivity in balance. 138 00:07:32.430 --> 00:07:36.840 So remember, dynamic security controls 139 00:07:36.840 --> 00:07:41.010 are automated measures that adjust security settings 140 00:07:41.010 --> 00:07:46.010 based on detected threats or changes in network behavior 141 00:07:46.050 --> 00:07:48.540 to keep systems protected. 142 00:07:48.540 --> 00:07:52.680 Two main components of dynamic security controls 143 00:07:52.680 --> 00:07:57.660 are event-based triggers and auto-containment. 144 00:07:57.660 --> 00:08:01.800 Event-based triggers activate when certain conditions 145 00:08:01.800 --> 00:08:03.510 like a malware signature 146 00:08:03.510 --> 00:08:08.100 or unusual login are detected, allowing the system 147 00:08:08.100 --> 00:08:11.730 to respond immediately to potential threats. 148 00:08:11.730 --> 00:08:16.320 Next, auto-containment works by isolating suspicious files 149 00:08:16.320 --> 00:08:19.650 or devices from the rest of the network, 150 00:08:19.650 --> 00:08:22.560 preventing possible threats from spreading 151 00:08:22.560 --> 00:08:25.830 while allowing for further investigation. 152 00:08:25.830 --> 00:08:30.450 Together, these tools provide a proactive automated defense 153 00:08:30.450 --> 00:08:34.563 that adapts in real time to keep systems secure.
