Fix Recommendation

Configure Libreswan to use the system cryptographic policy.

Add the following line to "/etc/ipsec.conf":

include /etc/crypto-policies/back-ends/libreswan.config

Check Contents

Note: If the IPsec service is not installed, this is not applicable.

Verify the IPsec service uses the system crypto policy with the following command:

$ sudo grep include /etc/ipsec.conf /etc/ipsec.d/*.conf

/etc/ipsec.conf:include /etc/crypto-policies/back-ends/libreswan.config
/etc/ipsec.conf:include /etc/ipsec.d/*.conf

If the ipsec configuration file does not contain "include /etc/crypto-policies/back-ends/libreswan.config", this is a finding.
