Discussion

File integrity tools often use cryptographic hashes for verifying that file contents have not been altered. These hashes must be FIPS 140-2 approved.

Check Content

If using an Advanced Intrusion Detection Environment (AIDE), verify the configuration contains the "sha256" or "sha512" options for all monitored files and directories.


Procedure:
Check for the default location /etc/aide/aide.conf
or:
# find / -name aide.conf

# egrep "[+]?(sha256|sha512)" <aide.conf file>
If the option is not present. This is a finding.
If one of these options is not present. This is a finding.

If using a different file integrity tool, check the configuration per tool documentation.

Fix Text

If using AIDE, edit the configuration and add the "sha512" option for all monitored files and directories.

If using a different file integrity tool, configure FIPS 140-2 approved cryptographic hashes per the tool's documentation.
