1.293 RHEL-10-700010

Information

RHEL 10 must display the Standard Mandatory DOD Notice and Consent Banner before granting local or remote access to the system via a Secure Shell (SSH) login.

GROUP ID: V-281224
RULE ID: SV-281224r1184753

The warning message reinforces policy awareness during the login process and facilitates possible legal action against attackers. Alternatively, systems whose ownership should not be obvious should ensure use of a banner that does not provide easy attribution.

OpenSSH uses the first occurrence of a keyword it sees, and drop-in files are read in lexicographical order at the start of the configuration. Red Hat recommends using drop-in files rather than changing base configuration files.

Solution

Configure RHEL 10 to display the Standard Mandatory DOD Notice and Consent Banner before granting access to the system via SSH.

Edit a file in "/etc/ssh/sshd_config.d" to uncomment or add the banner keyword and configure it to point to a file that will contain the login banner (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).

An example configuration line is:

Banner /etc/issue
