Ensure gpgcheck Enabled for Repository Metadata
An XCCDF Rule
Description
Verify the operating system prevents the installation of patches,
service packs, device drivers, or operating system components of
local packages without verification of the repository metadata.
Check that dnf verifies the repository
metadata prior to install with the following command.
This should be configured by setting repo_gpgcheck to 1
in /etc/dnf/dnf.conf.
Rationale
Changes to any software components can have significant effects to the overall security of the operating system. This requirement ensures the software has not been tampered and has been provided by a trusted vendor. Accordingly, patches, service packs, device drivers, or operating system components must be signed with a certificate recognized and approved by the organization. Verifying the authenticity of the software prior to installation validates the integrity of the patch or upgrade received from a vendor. This ensures the software has not been tampered with and that it has been provided by a trusted vendor. Self-signed certificates are disallowed by this requirement. The operating system should not have to verify the software again. NOTE: For U.S. Military systems, this requirement does not mandate DoD certificates for this purpose; however, the certificate used to verify the software must be from an approved Certificate Authority.
