Check Text (C-258232r1045440_chk)

Verify that the IPsec service uses the system crypto policy with the following command: Note: If the ipsec service is not installed, this requirement is Not Applicable. $ sudo grep include /etc/ipsec.conf /etc/ipsec.d/*.conf /etc/ipsec.conf:include /etc/crypto-policies/back-ends/libreswan.config If the ipsec configuration file does not contain "include /etc/crypto-policies/back-ends/libreswan.config", this is a finding.

Fix Text (F-61897r926682_fix)

Configure Libreswan to use the system cryptographic policy. Add the following line to "/etc/ipsec.conf": include /etc/crypto-policies/back-ends/libreswan.config
