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
