Walk into the module and title defense and depth model or how not to become an easy target.
In this module I'd like to show you a strategy for effective computer system protection that has been
developed for military purposes and was subsequently adopted by computer system security specialists.
This model is also described as layered security commonly compared to an onion.
I'd like to explain to you why this model has replaced one line defense strategies.
Such strategies assume that one security mechanism is enough.
It's been a common opinion that computers behind the firewall are safe because all unsafe computers
are outside.
We will use a few realistic scenarios that although based on simplified and optimistic assumptions will
help us examine the effectiveness of the defense in-depth strategy.
We will analyze this model against the ten immutable laws of computer system security these laws were
created more than a decade ago by Scott Cole an I.T. security specialist at Microsoft.
We will determine if these 10 laws are still valid.
If the general rules and guidelines created by Scott Koepp are still applicable Let's start the seminar.
