Fix Recommendation

Configure the system to run in FIPS mode. Add "fips=1" to the kernel parameter during the Ubuntu operating systems install.

Enabling a FIPS mode on a pre-existing system involves a number of modifications to the Ubuntu operating system. Refer to the Ubuntu Server 18.04 FIPS 140-2 security policy document for instructions.

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

Check Contents

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

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

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