Check Text (C-271743r1092635_chk)
Note: If the IPsec service is not installed, this requirement is Not Applicable.
Verify that the IPsec service uses the systemwide cryptographic policy with the following command:
$ 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-75700r1092602_fix)
Configure IPsec to use the systemwide cryptographic policy.
Add the following line to "/etc/ipsec.conf":
include /etc/crypto-policies/back-ends/libreswan.config
