“Which of the following BEST describes the concept of “”defense in depth””?”

more than one subsystem needs to be compromised to compromise the security of the system
and the information it holds.

B.
multiple firewalls are implemented.

C.
multiple firewalls and multiple network OS are implemented.

D.

E.
None of the choices.

Explanation:

“With 0″”defense in depth””, more than one subsystem needs to be compromised to compromise
the security of the system and the information it holds. Subsystems should default to secure
settings, and wherever possible should
be designed to “”fail secure”” rather than “”fail insecure””.”
