Title

FIPS 140-2/140-3 mode must be enabled on SLEM 5. (Cat I impact)

Discussion

Use of weak or untested encryption algorithms undermines the purposes of using encryption to protect data. SLEM 5 must implement cryptographic modules adhering to the higher standards approved by the federal government since this provides assurance they have been tested and validated.

Check Content

Verify SLEM 5 is running in FIPS mode by running the following command. > cat /proc/sys/crypto/fips_enabled 1 If the value returned is "0", nothing is returned, or the file does not exist, this is a finding.

Fix Text

To configure SLEM 5 to run in FIPS mode, add "fips=1" to the kernel parameter during SLEM 5 install. Enabling FIPS mode on a preexisting system involves a number of modifications to SLEM 5. Refer to section 9.1, "Crypto Officer Guidance", of the following document for installation guidance: http://csrc.nist.gov/groups/STM/cmvp/documents/140-1/140sp/140sp2435.pdf
