Hello, everyone. And welcome back to cyber is and user physical security. Course I'm your instructor. Corey holds her. And this is less than 3.1 reception
for this lesson. I have to learning objectives for you. First, we're gonna discuss building security at the exterior.
Then we're gonna move inside the building to the lobby and discuss physical security measures within the lobby.
So securing the exterior
now, a lot of the measures that we employ on the exterior of the building relates to the open space. Security was discussed in the last module, but here's some key highlights that are important specifically to securing the exterior.
First, we have 360 degree view cameras that give security professionals a good
360 degree view of what's going on around the building.
We have exit only doors now these you should be familiar with. I know I've seen them in a lot of public places movie theaters, for example.
And these doors air designed to allow people to exit the building. But if they were to try to re enter through the same door, the door is effectively locked.
There's an advantage. An important security feature for this first in the event of an emergency,
people don't have to worry about a door being unlocked. If they have to get out of the building, they can push on. The security bar opened the door and exit.
But the advantage for the second part of this is it's not an open door that some
adversary, some saboteur, some criminal could actually open up and enter the building.
Then you have to consider as well as thes two things. You have to consider certain security measures for vulnerable access points around the building.
So what are some of those securing vulnerabilities that we have to consider? Well, first, I talked about the exit only doors. I won't touch on that again. But then you have things like Windows and air handlers.
Now I know air handles wouldn't come to mind as maybe a vulnerability. But the fact of the matter is, is that if air handlers
have vents at this at street level,
a would be adversary could theoretically breakthrough the great and then make his way through the air system
of the air handling events in order to get inside the building. And this would be a weak point if we left it at street level.
So the goal here is to move the air handlers up above street level, where they can be access, whether it's on the roof or high up on the walls of the building, where someone
on the ground level couldn't actually access them.
Another thing to consider or windows.
It's important that we have windows at the ground level and maybe even, maybe at the second story level. It's important when we consider Windows to think about them as an egress from the building. In the case of some
ah danger, whether it's fire an active shooter, what have you.
But we also don't want to allow
those people who would choose to do the business harm the ability to get in so we can use things like window pins, and that's simply a measure like you see in the picture. On the right hand side,
it's simply one where you can.
The pin secures the window from being open from the outside, but remove the pin, slide the window over. It is now on egress for anyone who is inside the building in the event and who needs to get out in the event of a fire, and this is their only exit.
So now we get to lobby designed lobby design is critical
on a lot of levels.
It is the company's first opportunity to really impress
potential clients, potential customers.
So it has to be inviting.
And that's a duality, because there's a challenge now that how do we make it inviting but keep everyone secure?
Well, to be honest,
we can use it as a buffer zone
the same way Open space was used as a buffer zone between the perimeter and the front door.
The lobby itself could be open
to allow people in.
But then is that buffer
before people can actually enter the sensitive areas of the building where the business is being conducted.
This is also where we can place our security.
I've worked in many buildings where that security presence also acts as reception for
visitors, for guests,
This is their opportunity to ask for proof of identity, to ask the person what their businesses and to also start processing them into the building. It's basically controlling foot traffic,
what kind of security functions
can be performed in lobby. Well,
like I said, physical security, the security force is that first presence that they see.
So this is where we can process the visitors. We can also use things like bag scanners
or full body scanners to
to scan visitors as they come in.
We don't actually want them bringing something in from outside that that shouldn't be in the building.
So this is why we do that. We can also do it as as an opportunity
to even just visually examine their bags.
We also challenged them. Who are you here to see?
Are they expecting you?
And this is a good opportunity to keep them in place
until escort arrives to escort them through the building.
So let's do our check on learning.
Which of the following is a passive security method
lobby design or authenticating individuals?
The answer's lobby design. Well, there's an active design element. In the beginning,
the lobby functions as a holding area or a welcoming location.
visitors, guests, employees, contractors, dignitaries, etcetera.
But it doesn't do anything in its layout
other than control, where those people can go until they've been properly vetted and can be welcomed into the proper interior of the building.
In this lesson we discussed to care is first we looked at it the physical security at the exterior of the building.
And then we brought everybody into the lobby and looked at lobby security measures that are in place in most buildings these days.
I want to thank you for taking the time to take this class with me, and I look forward to seeing you in the next lesson.
