1 00:00:00,590 --> 00:00:02,700 The first part of securing your organization 2 00:00:02,700 --> 00:00:04,730 is maintaining a good perimeter defense 3 00:00:04,730 --> 00:00:06,050 around your building. 4 00:00:06,050 --> 00:00:08,210 Now, based on your organization, this is going 5 00:00:08,210 --> 00:00:09,880 to have different requirements based 6 00:00:09,880 --> 00:00:11,350 on what kind of work you do. 7 00:00:11,350 --> 00:00:14,300 For example, if you work for the government or the military, 8 00:00:14,300 --> 00:00:16,610 you may be dealing with classified information 9 00:00:16,610 --> 00:00:19,410 and if that's the case, you may see a big eight foot tall 10 00:00:19,410 --> 00:00:21,120 chain link fence with barbed wire 11 00:00:21,120 --> 00:00:23,170 at the top surrounding the building. 12 00:00:23,170 --> 00:00:25,070 You may have access control points that are guarded 13 00:00:25,070 --> 00:00:26,370 by soldiers with guns. 14 00:00:26,370 --> 00:00:28,490 There might be vehicle barricades, there might be 15 00:00:28,490 --> 00:00:30,490 other such things that are going to keep people 16 00:00:30,490 --> 00:00:32,340 away from the building unless they're authorized 17 00:00:32,340 --> 00:00:33,250 to be there. 18 00:00:33,250 --> 00:00:35,150 This makes sense for them, right, because they're dealing 19 00:00:35,150 --> 00:00:37,380 with secret and top secret information 20 00:00:37,380 --> 00:00:39,000 and they want to make sure nobody gets access 21 00:00:39,000 --> 00:00:40,330 to it that shouldn't. 22 00:00:40,330 --> 00:00:42,620 Now, your company probably doesn't have this level 23 00:00:42,620 --> 00:00:43,580 of security, though. 24 00:00:43,580 --> 00:00:45,910 And instead, they're going to rely on surveillance cameras 25 00:00:45,910 --> 00:00:47,900 and closed-circuit TV. 26 00:00:47,900 --> 00:00:49,810 Now, when we talk about closed-circuit TV 27 00:00:49,810 --> 00:00:52,000 or CCTV as it's also called, 28 00:00:52,000 --> 00:00:54,320 these come in lots of different solutions. 29 00:00:54,320 --> 00:00:57,060 The first two types are wired and wireless. 30 00:00:57,060 --> 00:01:00,020 A wired solution means that this TV camera 31 00:01:00,020 --> 00:01:01,920 that's being placed around your building is going 32 00:01:01,920 --> 00:01:04,970 to be physically cabled from its device, all the way 33 00:01:04,970 --> 00:01:06,890 to a central monitoring station. 34 00:01:06,890 --> 00:01:08,470 Now, if you're using a wireless solution, 35 00:01:08,470 --> 00:01:10,150 these are a lot easier to install 36 00:01:10,150 --> 00:01:12,530 but because they're wireless, they could have interference 37 00:01:12,530 --> 00:01:15,860 with other systems and an attacker could try to jam them. 38 00:01:15,860 --> 00:01:17,570 There's also indoor and outdoor, 39 00:01:17,570 --> 00:01:20,810 some CCTV systems are only designed to work indoors 40 00:01:20,810 --> 00:01:22,630 and others are used for outdoors. 41 00:01:22,630 --> 00:01:24,150 If you're going to be monitoring the parking lot, 42 00:01:24,150 --> 00:01:26,220 you need an outdoor camera that's going to be able 43 00:01:26,220 --> 00:01:28,340 to stand up to the elements like rain 44 00:01:28,340 --> 00:01:30,050 and snow and things like that. 45 00:01:30,050 --> 00:01:31,940 If you're going to be monitoring things indoors, 46 00:01:31,940 --> 00:01:33,710 like access to and from server rooms, 47 00:01:33,710 --> 00:01:36,490 access to and from the lobby, this would be something 48 00:01:36,490 --> 00:01:38,310 you could use an indoor camera for. 49 00:01:38,310 --> 00:01:39,780 They're a lot cheaper because they don't have 50 00:01:39,780 --> 00:01:43,350 to be held up to that standard that works in the outside. 51 00:01:43,350 --> 00:01:45,630 Another feature you might want to look at with your CCTV 52 00:01:45,630 --> 00:01:50,020 is what's known as PTZ which is pan, tilt, and zoom. 53 00:01:50,020 --> 00:01:51,980 This is what you might've seen in some movies. 54 00:01:51,980 --> 00:01:54,650 If there's a security guard as in part of the bank heist 55 00:01:54,650 --> 00:01:57,120 and he's able to take a joystick and move the camera 56 00:01:57,120 --> 00:02:00,160 to look at different direction and tilt it up and down, 57 00:02:00,160 --> 00:02:03,140 pan it left and right, or zoom in or zoom out. 58 00:02:03,140 --> 00:02:05,360 That's a PTZ system. 59 00:02:05,360 --> 00:02:06,920 Another type of system we have is what's known 60 00:02:06,920 --> 00:02:09,290 as an infrared system, which looks at things based 61 00:02:09,290 --> 00:02:11,310 on their heat, as you can see in this image. 62 00:02:11,310 --> 00:02:13,160 You could see the laptop is producing heat 63 00:02:13,160 --> 00:02:14,680 and we'd be able to see it. 64 00:02:14,680 --> 00:02:16,870 The final type is what's known as ultrasonic, 65 00:02:16,870 --> 00:02:19,060 which is used for sound-based detection. 66 00:02:19,060 --> 00:02:20,930 If you've ever watched the Mission Impossible movies, 67 00:02:20,930 --> 00:02:23,210 they had an ultrasonic system that would sit there 68 00:02:23,210 --> 00:02:26,040 and listen, if even a pin dropped on the floor, 69 00:02:26,040 --> 00:02:28,660 it would set off the alarm and that way this guard 70 00:02:28,660 --> 00:02:31,340 could come running in and arrest the perpetrator. 71 00:02:31,340 --> 00:02:32,910 Now, when you place your cameras, 72 00:02:32,910 --> 00:02:34,550 placement is really important 73 00:02:34,550 --> 00:02:36,800 and you have to figure out what are you trying to guard. 74 00:02:36,800 --> 00:02:38,160 Most of the time, you're trying 75 00:02:38,160 --> 00:02:40,400 to guard your entrances and your exits. 76 00:02:40,400 --> 00:02:42,570 If you're pointing the cameras at the entrance or exits, 77 00:02:42,570 --> 00:02:44,010 you'll be able to see when people enter 78 00:02:44,010 --> 00:02:45,370 or leave the facility. 79 00:02:45,370 --> 00:02:48,060 This would be both the entrance and exit of your building 80 00:02:48,060 --> 00:02:52,727 but also of your server room and other secure locations.
