The EPEL is a repository of high-quality open-source packages for enterprise-class Linux distributions such as RHEL, CentOS, AlmaLinux, Rocky Linux, and Oracle Linux. These packages are not part of the official distribution but are built using the same Fedora build system to ensure compatibility and maintain quality standards.
Check
Verify OL 7 is not able to install packages from the EPEL with the following command:
# yum repolist enabled | grep -i 'epel'
If any output is returned, this is a finding.
Fix
Configure OL7 to not have access to the EPEL repo.
