Hello everyone my name is vijay kumar Devireddy and I am glad to have you back on my episode 89 today we're going to discuss about The first part of securing your organization is maintaining a good perimeter defense around your building.Now based on your organization this is going to have different requirements based on what kind of work you do.For example, if you work for the government or the military, you may be dealing with classified information and if that's the case you may see a big eight foot tall chain link fence with barbed wire at the top surrounding the building.You may have access control points that are guarded by soldiers with guns.There might be vehicle barricades, there might be other such things that are going to keep people away from the building unless they're authorized to be there.This makes sense for them right because they're dealing with secret and top secret information and they want to make sure nobody gets access to it that shouldn't Now your company probably doesn't have this level of security though. And instead they're going to rely on surveillance cameras and closed circuit TV.Now when we talk about closed circuit TV or CCTV as it's also called, these come in lots of different solutions.The first two types are wired and wireless.A wired solution means that this TV camera that's being placed around your building is going to be physically cabled from its device all the way to a central monitoring station.Now if you're using a wireless solution, these are a lot easier to install but because they're wireless they could have interference with other systems and an attacker could try to jam them. There's also indoor and outdoor,some CCTV systems are only designed to work indoors and others are used for outdoors. If you're going to be monitoring the parking lot, you need an outdoor camera that's going to be able to stand up to the elements like rain and snow and things like that.If you're going to be monitoring things indoors,like access to and from server room access to and from the lobby, this would be something you could use an indoor camera for.They're a lot cheaper because they don't have to be held up to that standard that works in the outside. Another feature you might want to look at with your CCTV is what's known as PTZ which is pan, tilt, and zoom. This is what you might've seen in some movies.If there's a security guard as in part of the bank heist and he's able to take a joystick and move the camera to look a different direction and tilt it up and down, pan it left and right, or zoom in or zoom out.That's a PTZ system. Another type of system we have is what's known as an infrared system which looks at things based on their heat, as you can see in this image.You could see the laptop is producing heat and we'd be able to see it. The final type is what's known as ultrasonic which is used for sound-based detection.If you've ever watched the Mission Impossible movies,they had an ultrasonic system that would sit there and listen, if even a pin dropped on the floor,it would set off the alarm and that way this guards could come running in and arrest the perpetrator.Now when you place your cameras, placement is really importantand you have to figure out what are you trying to guard.Most of the time you're trying to guard your entrances and your exits.If you're pointing the cameras at the entrance or exits, you'll be able to see when people enter or leave the facility.This would be both the entrance and exit of your building but also of your server room and other secure locations.
