RHEL-07-010019 - The Red Hat Enterprise Linux operating system must ensure cryptographic verification of vendor software packages.

Information

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.

Solution

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

Insert RHEL 7 installation disc or attach RHEL 7 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.
