| Verify the SSH daemon performs privilege separation. Check that the SSH daemon performs privilege separation with the following command: # grep -i usepriv /etc/ssh/sshd_config UsePrivilegeSeparation sandbox If the "UsePrivilegeSeparation" keyword is set to "no", is missing, or the returned line is commented out, this is a finding. |
| Fix Text (F-23567r419662_fix) |
|---|
| Uncomment the "UsePrivilegeSeparation" keyword in "/etc/ssh/sshd_config" (this file may be named differently or be in a different location if using a version of SSH that is provided by a third-party vendor) and set the value to "sandbox" or "yes": UsePrivilegeSeparation sandbox The SSH service must be restarted for changes to take effect. |
