Check Text (C-281014r1165397_chk)
Note: If the IPsec service is not installed, this requirement is not applicable.
Verify RHEL 10 sets the IPsec service to use the systemwide cryptographic 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
If the ipsec configuration file does not contain "include /etc/crypto-policies/back-ends/libreswan.config", this is a finding.
Fix Text (F-85480r1165396_fix)
Configure RHEL 10 so that Libreswan uses the systemwide cryptographic policy.
Add the following line to "/etc/ipsec.conf":
include /etc/crypto-policies/back-ends/libreswan.config
