Check Text (C-217278r991589_chk)
Determine the version of SSH using the following command:
# ssh -V
OpenSSH_7.9p1
If the version of SSH is 7.5 or newer, this is Not Applicable.
Verify the SUSE operating system SSH daemon is configured to use privilege separation.
Check that the SUSE operating system SSH daemon performs privilege separation with the following command:
# sudo grep -i usepriv /etc/ssh/sshd_config
UsePrivilegeSeparation yes
If the "UsePrivilegeSeparation" keyword is not set to "yes" or "sandbox", is missing, or the returned line is commented out, this is a finding.
Fix Text (F-18504r369991_fix)
Configure the SUSE operating system SSH daemon is configured to use privilege separation.
Uncomment the "UsePrivilegeSeparation" keyword in "/etc/ssh/sshd_config" and set the value to "yes" or "sandbox":
UsePrivilegeSeparation yes
