Fix Recommendation

Configure Libreswan to use the systemwide cryptographic policy.

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

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

Check Contents

Note: If the Libreswan package is not installed, this requirement is Not Applicable.

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

$ grep -rE '^include ' /etc/ipsec.conf /etc/ipsec.d/

/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.
