Description
Overriding the systemwide cryptographic policy makes the behavior of the Libreswan service violate expectations and makes system configuration more fragmented.
ℹ️ Check
Note: If the IPsec service is not installed, this requirement is Not Applicable.
Verify the SUSE operating system sets the IPsec service to use the systemwide cryptographic policy with the following command:
> sudo grep -s 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
Configure the SUSE operating system so that Libreswan uses the systemwide cryptographic policy.
Add the following line to "/etc/ipsec.conf":
include /etc/crypto-policies/back-ends/libreswan.config
