Which is the correct rule in the following Rule Base?

A.
Rule 2

B.
Rule 1

C.
Rule 3

D.
Rule 4

E.
None of the rules allow access.

Explanation:
Rule 1 is the entry to apply to our rulebase, in this rule we are including all the users defined at
Chicago , giving access to any service at any destination always that the session could be
authenticated. This rule is the only one that covers the needs of the questions in a 100%.
Incorrect Answers:
A: Rule 2 is incorrect since you cannot have the users at the same source to the same destination,
in this fashion, the traffic is local and it doesn’t need to pass though the gateway. That is not a
good practice.
D: Putting “ANY” on the service entry is not correct because user authentication only works with
HTTP, Telnet, FTP and RLogin, not with “ANY” service.
