Description
This requirement applies to both internal and external networks. Terminating network connections associated with communications sessions means de-allocating associated TCP/IP address/port pairs at the operating system level. The time period of inactivity may, as the organization deems necessary, be a set of time periods by type of network access or for specific accesses.

Determine if SSH is configured to disconnect sessions after 10 minutes of inactivity. # grep ClientAlive /etc/ssh/sshd_config If the output of this command is not: ClientAliveInterval 600 ClientAliveCountMax 0 this is a finding.

Fix Text (F-17590r371157_fix)

The root role is required. Configure the system to disconnect SSH sessions after 10 minutes of inactivity. Modify the sshd_config file: # pfedit /etc/ssh/sshd_config Modify or add the lines containing: ClientAliveInterval ClientAliveCountMax Change them to: ClientAliveInterval 600 ClientAliveCountMax 0 Restart the SSH service: # svcadm restart svc:/network/ssh
