Description
Installation of any nontrusted software, patches, service packs, device drivers, or operating system components can significantly affect the overall security of the operating system. This requirement ensures the software has not been tampered with and has been provided by a trusted vendor.

Check Text (C-258846r1015948_chk)

At the command line, run the following command to verify software packages are cryptographically verified during installation: # grep '^gpgcheck' /etc/tdnf/tdnf.conf Example result: gpgcheck=1 If "gpgcheck" is not set to "true", "1", or "yes", this is a finding.

Fix Text (F-62495r933598_fix)

Navigate to and open: /etc/tdnf/tdnf.conf Add or update the following line: gpgcheck=1
