Discussion

Overriding the system crypto policy makes the behavior of the Libreswan service violate expectations, and makes system configuration more fragmented.

Check Content

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

Note: If the IPsec service is not installed, this 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

Configure Libreswan to use the system cryptographic policy.

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

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