Title
The ESXi host SSH daemon must set a timeout count on idle sessions. (Cat III impact)
Discussion
This ensures a user login will be terminated as soon as the "ClientAliveCountMax" is reached.
Check Content
From an SSH session connected to the ESXi host, or from the ESXi shell, run the following command: # grep -i "^ClientAliveCountMax" /etc/ssh/sshd_config If there is no output or the output is not exactly "ClientAliveCountMax 3", this is a finding.
Fix Text
From an SSH session connected to the ESXi host, or from the ESXi shell, add or correct the following line in "/etc/ssh/sshd_config": ClientAliveCountMax 3
