Fix Recommendation

Configure RHEL 10 software repositories defined in "/etc/yum.repos.d/" to have "gpgcheck" enabled with the following command:

$ sudo sed -i 's/gpgcheck\s*=.*/gpgcheck=1/g' /etc/yum.repos.d/*

Check Contents

Verify RHEL 10 software repositories defined in "/etc/yum.repos.d/" have been configured with "gpgcheck" enabled with the following command:

$ sudo grep -w gpgcheck /etc/yum.repos.d/*.repo | more
gpgcheck = 1

If "localpkg_gpgcheck" is not set to "1", or if the option is missing or commented out, ask the system administrator how the GPG signatures of local software packages are being verified.

If no process to verify GPG signatures has been approved by the organization, this is a finding.
