Discussion

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 Content

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

Navigate to and open:

/etc/tdnf/tdnf.conf

Add or update the following line:

gpgcheck=1
