| V-216119 | SOL-11.1-040380 | SV-216119r970703_rule | CCI-001133 | low |
| 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. | ||||

Check Text (C-216119r970703_chk)
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-17355r372740_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
