Fix Recommendation

Configure the two user-configurable parameters that affect session termination (TCP segment lifetime and authentication credential inactivity timeout).

Configure the TCP segment lifetime setting (default is 120 seconds).
1. SSH into the ProxySG console and type "enable" and then "configure".
2. Type "tcp-ip tcp 2msl 900", for example, to set the timeout to 900 seconds (the default).

Configure the authentication credential inactivity timeouts.
1. Log on to the Web Management Console.
2. Browse to Configuration >> Authentication.
3. For each authentication method listed, click it and then the "General" tab and set the "Inactivity timeout" to 600 seconds or less (default is 900 seconds).
4. Click "Apply".

Check Contents

Check the two user-configurable parameters that affect session termination (TCP segment lifetime and authentication credential inactivity timeout).

Check the TCP segment lifetime setting (default is 120 seconds).
1. SSH into the ProxySG console and type "show tcp-ip".
2. Verify that the TCP 2MSL timeout is set to 600 seconds or less.

Check the authentication credential inactivity timeouts.
1. Log on to the Web Management Console.
2. Browse to Configuration >> Authentication.
3. For each authentication method listed, click it and then the "General" tab and verify that the "Inactivity timeout" is set to 600 seconds or less (default is 900 seconds).

If Symantec ProxySG does not terminate all network connections associated with a communications session at the end of the session, or terminate user sessions (nonprivileged session) after 15 minutes of inactivity, this is a finding.
