System Administrators use session authentication when they want users to:

A.
Authenticate each time they use a supported service.

B.
Authenticate all services.

C.
Use only TENET, FTP, RLOGIN, and HTTP services.

D.
Authenticate once, and then be able to use any service until logging off.

E.
Both B and D

Explanation:
with session authentication we can authenticate all the services in a transparent way because all
the authentication request are made between the session authentication agent and the firewall
object. The user doesn’t worry about authenticating each type of service.
Incorrect Answers:
A: This is not the case, remember that we have the session authentication agent installed in the
PC.
C: This is the case of User authentication, not Session authentication.
D: This is not true, because by default we have an expiration time for our sessions.
E: This answer is wrong because it takes answer “D” as correct.
