Verify RHEL 10 dnf always checks the GPG signature of software packages originating from external software repositories before installation with the following command: $ sudo grep -w gpgcheck /etc/dnf/dnf.conf gpgcheck=1 If "gpgcheck" is not set to either "1", "true", or "yes" (keywords containing letters are case insensitive), or if the option is missing or commented out, ask the system administrator how the GPG signatures of software packages are being verified. If no process to verify GPG signatures has been approved by the organization, this is a finding.

Add or update the following line in the [main] section of the "/etc/dnf/dnf.conf" file: gpgcheck=1 Note: Any of the following are acceptable: "1", "true", or "yes" (keywords containing letters are case insensitive).
