Fix Recommendation

To ensure signature checking is not disabled for any repos, remove any lines from files in "/etc/yum.repos.d" of the form:

gpgcheck=0

Check Contents

To determine whether "yum" has been configured to disable "gpgcheck" for any repos, inspect all files in "/etc/yum.repos.d" and ensure the following does not appear in any sections:

gpgcheck=0

A value of "0" indicates that "gpgcheck" has been disabled for that repo.
If GPG checking is disabled, this is a finding.

If the "yum" system package management tool is not used to update the system, verify with the SA that installed packages are cryptographically signed.
