1.210 RHEL-09-255045

Information

RHEL 9 must not permit direct logons to the root account using remote access via SSH.

GROUP ID: V-257985
RULE ID: SV-257985r1069364

Even though the communications channel may be encrypted, an additional layer of security is gained by extending the policy of not logging directly on as root. In addition, logging in with a user-specific account provides individual accountability of actions performed on the system and also helps to minimize direct attack attempts on root's password.

Satisfies: SRG-OS-000109-GPOS-00056, SRG-OS-000480-GPOS-00227

Solution

To configure the system to prevent SSH users from logging on directly as root add or modify the following line in "/etc/ssh/sshd_config" or in a file in "/etc/ssh/sshd_config.d".

PermitRootLogin no

Restart the SSH daemon for the settings to take effect:

$ sudo systemctl restart sshd.service
