Title

RHEL 8 IP tunnels must use FIPS 140-3-approved cryptographic algorithms. (Cat II impact)

Discussion

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

Check Content

Note: If the ipsec service is not installed, this requirement is Not Applicable. Verify the IPsec service uses the system crypto 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 /etc/ipsec.conf:include /etc/ipsec.d/*.conf 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
