RHEL 9 must ensure cryptographic verification of vendor software packages.

An XCCDF Rule

Description

Cryptographic verification of vendor software packages ensures that all software packages are obtained from a valid source and protects against spoofing that could lead to installation of malware on the system. Red Hat cryptographically signs all software packages, which includes updates, with a GPG key to verify that they are valid.

Remediation Templates

Install Red Hat package-signing keys on the system and verify their fingerprints match vendor values.

Insert RHEL 9 installation disc or attach RHEL 9 installation image to the system. Mount the disc or image to make the contents accessible inside the system.

Assuming the mounted location is "/media/cdrom", use the following command to copy Red Hat GPG key file onto the system:
$ sudo cp /media/cdrom/RPM-GPG-KEY-redhat-release /etc/pki/rpm-gpg/
	 
Import Red Hat GPG keys from key file into system keyring:

$ sudo rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release
	 
Using the steps listed in the Check Text, confirm the newly imported keys show as installed on the system and verify their fingerprints match vendor values.
