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. Cryptographically verifying the authenticity of all software packages during installation 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:

# grep gpgcheck /etc/yum.repos.d/*

If "gpgcheck" is not set to "1" in any returned file, this is a finding.

Fix Text

Open the file where "gpgcheck" is not set to "1" with a text editor.

Remove any existing "gpgcheck" setting and add the following line at the end of the file:

gpgcheck=1
