| Description |
|---|
| SSH daemon privilege separation causes the SSH process to drop root privileges when not needed, which would decrease the impact of software vulnerabilities in the unprivileged section. |
| ℹ️ Check |
|---|
| 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 |
|---|
| Edit the "/etc/sshd/sshd_config" file and add the following line: UsePrivilegeSeparation yes Restart the SSH daemon: # stopsrc -s sshd # startsrc -s sshd |
