1.2.3 Ensure gpgcheck is globally activated

Information

The gpgcheck option, found in the main section of the /etc/yum.conf and individual /etc/yum/repos.d/*.repo files determines if an RPM package's signature is checked prior to its installation.

Rationale:

It is important to ensure that an RPM's package signature is always checked prior to installation to ensure that the software is obtained from a trusted source.

Solution

Edit /etc/yum.conf and set 'gpgcheck=1' in the [main] section.
Edit any failing files in /etc/yum.repos.d/*.repo and set all instances of gpgcheck to 1.
