Description:
The /etc/ssh/sshd_config file contains configuration specifications for sshd. The
command below sets the owner and group of the file to root.
Rationale:
The /etc/ssh/sshd_config file needs to be protected from unauthorized changes by non-privileged users.
Audit:
Run the following command and verify Uid and Gid are both 0/root and Access does not
grant permissions to group or other:
# stat /etc/ssh/sshd_config
Access: (0600/-rw-------) Uid: ( 0/ root) Gid: ( 0/ root)
Remediation:
Run the following commands to set ownership and permissions on /etc/ssh/sshd_config:
# chown root:root /etc/ssh/sshd_config
# chmod og-rwx /etc/ssh/sshd_config
Parameter:
[root, root, 110000000]
Technical Mechanism:
Run the following commands to set ownership and permissions on /etc/ssh/sshd_config:
# chown root:root /etc/ssh/sshd_config
# chmod og-rwx /etc/ssh/sshd_config
