Which one of the following security areas is directly addressed by Kerberos?

A.
Confidentiality

B.
Frequency analysis

C.
Availability

D.
Physical attacks

Explanation:
Kerberos directly addresses the confidentiality and also the integrity of information. * attacks such
as frequency analysis are not considered in the basic Kerberos implementation. In addition, the
Kerberos protocol does not directly address availability issues. (Answer Availability.) For answer
“Physical attac”, since the Kerberos TGS and the authentication servers hold all the secret keys,
these servers are vulnerable to both physical attacks and attacks from malicious code. In the
Kerberos exchange, the client workstation temporarily holds the client’s secret key, and this key is
vulnerable to compromise at the workstation.
