Fix Recommendation

Configure Ubuntu 22.04 LTS to run in FIPS mode. Add "fips=1" to the kernel parameter during Ubuntu 22.04 LTS install.

Enabling a FIPS mode on a pre-existing system involves a number of modifications to Ubuntu 22.04 LTS. Refer to the Ubuntu Pro security certification documentation for instructions.

A subscription to the "Ubuntu Pro" plan is required to obtain the FIPS Kernel cryptographic modules and enable FIPS.

Note: Ubuntu Pro security certification instructions can be found at: https://ubuntu.com/security/certifications/docs/fips-enablement

Check Contents

Verify the system is configured to run in FIPS mode by using the following command:

$ grep -i 1 /proc/sys/crypto/fips_enabled
1

If a value of "1" is not returned, this is a finding.
