>> Okay guys, in this section,
00:00
we'll talk about reducing
00:00
the attack surface. The idea
00:00
here is that some software like
00:00
operating systems can really be bloated and contain
00:00
a lot of applications and
00:00
services that may not be necessary.
00:00
But the more services and
00:00
applications you have running on a system,
00:00
the larger the system is,
00:00
and that also means it has a larger attack surface.
00:00
So if you can uninstall or
00:00
disable some of the unnecessary services,
00:00
you can reduce the attack surface and harden
00:00
the system. But it's more than just reducing
00:00
the amount of extra software or hardware.
00:00
Reducing the attack service also involves patching
00:00
and updating your systems
00:00
to make them a harder to attack.
00:00
Now before we talk about hardening our systems,
00:00
we also need to think about hardening our facilities.
00:00
Now, when it comes to where
00:00
your facility should be placed,
00:00
we want to think about somewhere
00:00
where there is natural surveillance.
00:00
You don't want to be at the end of
00:00
a driveway off the road, rather you'd
00:00
want to be somewhere where there is a lot of
00:00
traffic or in an area that is frequently observed.
00:00
Fences are helpful, but they should be
00:00
eight feet high in order to DETER an intruder.
00:00
There is no height that will totally
00:00
prevent a determined intruder,
00:00
but you can't DETER someone.
00:00
In many cases, we were just looking to
00:00
use layered defense to slow an attacker down.
00:00
Lighting is important,
00:00
it should be eight feet high and overlaps
00:00
there are no dark areas that are not lightened.
00:00
Door should have hinges that are internal to the door
00:00
and not in a place where an attacker can pop them open.
00:00
For your windows, you want
00:00
to have the strongest available,
00:00
which are polycarbonate or Lexan,
00:00
such windows are bulletproof.
00:00
Security guards and man- traps are
00:00
important to stop someone from trying to force
00:00
their way in or
00:00
piggy-backing or tailgating on another person who has
00:00
access.. We went to log the entry and
00:00
exit of all visitors so you can
00:00
keep track of all the people who have had access.
00:00
If you really want to tightly control visitor access,
00:00
one thing you can do is require
00:00
a drivers license in exchange for the visitor's badge.
00:00
This helps ensure that when people
00:00
are actually who they say they are,
00:00
and also that they will return them
00:00
visitor's badge when they leave.
