Vulnerability 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)" 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.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
