Fix Recommendation

Configure the file integrity tool to use FIPS 140-3 cryptographic hashes for validating file and directory contents.

If AIDE is installed, ensure the "sha512" rule is present on all uncommented file and directory selection lists. Exclude any log files, or files expected to change frequently, to reduce unnecessary notifications.

Check Contents

Verify that AIDE is configured to use FIPS 140-3 file hashing with the following command:

$ sudo grep sha512 /etc/aide.conf

All=p+i+n+u+g+s+m+S+sha512+acl+xattrs+selinux

If the "sha512" rule is not being used on all uncommented selection lines in the "/etc/aide.conf" file, or another file integrity tool is not using FIPS 140-3-approved cryptographic hashes for validating file contents and directories, this is a finding.
