RHEL 10 must have the "libreswan" package installed.

Providing the ability for remote users or systems to initiate a secure virtual private network connection protects information when it is transmitted over a wide area network.

Note: If there is no operational need for Libreswan to be installed, this rule is not applicable.

Verify RHEL 10 has the "libreswan" service package installed with the following command:

$ sudo dnf list --installed libreswan Installed Packages libreswan.x86_64 5.2-1.el10_0 @AppStream

If the "libreswan" package is not installed, this is a finding.

Configure RHEL 10 to have the "libreswan" service package installed with the following command:

$ sudo dnf -y install libreswan
