The Oracle Linux operating system 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. Oracle cryptographically signs all software packages, which includes updates, with a GPG key to verify that they are valid.

Install Oracle package-signing key on the system and verify its fingerprint matches vendor value.

Insert OL 7 installation disc or attach OL 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 Oracle GPG key file onto the system:
     $ sudo cp /media/cdrom/RPM-GPG-KEY-oracle /etc/pki/rpm-gpg/
	 
Import Oracle GPG keys from key file into system keyring:

     $ sudo rpm --import /etc/pki/rpm-gpg/RPM-GPG-KEY-oracle
	 
Using the steps listed in the Check Text, confirm the newly imported key shows as installed on the system and verify its fingerprint matches vendor value.
