-After being authenticated by the Security Gateway, when a user starts an HTTP connection to a Web site, the user tries to FTP to another site using the command line. What happens to the user?
The:
A.
FTP connection is dropped by Rule 2.
B.
user is prompted from that FTP site only, and does not need to enter his username and
password for Client Authentication.
C.
user is prompted for authentication by the Security Gateway again.
D.
FTP data connection is dropped after the user is authenticated successfully.
Explanation:
“Required Sign On,” when set to “Standard,” means that once a user has
authenticated one time, they are permitted to access all services, as long as they
are allowed to do so according to the rule base.When set to “Specific,” users must
authenticate again for each new service they attempt to access.
“Sign-On Method” has the following five options:
0
0
Manual Users must use either telnet to port 259 on the firewall, or use
a Web browser to connect to port 900 on the firewall to authenticate
before being granted access.
Partially Automatic If user authentication is configured for the service
the user is attempting to access and they pass this authentication, then no
further client authentication is required. For example, if HTTP is permitted
on a client authentication rule, the user will be able to transparently
authenticate since FireWall-1 has a security server for HTTP.Then, if
this setting is chosen, users will not have to manually authenticate for this
connection. Note that this applies to all services for which FireWall-1 has
built-in security servers (HTTP, FTP, telnet, and rlogin).
Fully Automatic If the client has the session authentication agent
installed, then no further client authentication is required (see session
authentication below). For HTTP, FTP, telnet, or rlogin, the firewall will
authenticate via user authentication, and then session authentication will
be used to authenticate all other services.

Agent Automatic Sign On Uses session authentication agent to provide
transparent authentication (see session authentication below).
Single Sign-On System Used in conjunction with UserAuthority
servers to provide enhanced application level security. Discussion of
UserAuthority is beyond the scope of this book.
