Details
Check Text (C-215297r991589_chk)
Check the SSH daemon configuration for the "UsePrivilegeSeparation" setting using command:
# grep -i UsePrivilegeSeparation /etc/ssh/sshd_config | grep -v '^#'
UsePrivilegeSeparation yes
If the setting is not present or the setting is "no", this is a finding.
Fix Text (F-16493r294343_fix)
Edit the "/etc/sshd/sshd_config" file and add the following line:
UsePrivilegeSeparation yes
Restart the SSH daemon:
# stopsrc -s sshd
# startsrc -s sshd
