Fix Recommendation

Configure RHEL 10 so that the file integrity tool uses 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, and that no legacy hashes exist.

By default, AIDE excludes log files such as "/var/log" and other volatile files to reduce unnecessary notifications.

Check Contents

Verify RHEL 10 AIDE is configured to use FIPS 140-3 file hashing.

Verify global default hash settings with the following command:

$ sudo grep -iE 'sha|md5|rmd' /etc/aide.conf | grep -v ^#
FIPSR = p+i+n+u+g+s+m+ftype+growing+acl+selinux+xattrs+sha512
ALLXTRAHASHES = sha512
/usr/sbin/auditctl p+i+n+u+g+s+b+acl+xattrs+sha512
/usr/sbin/auditd p+i+n+u+g+s+b+acl+xattrs+sha512
/usr/sbin/ausearch p+i+n+u+g+s+b+acl+xattrs+sha512
/usr/sbin/aureport p+i+n+u+g+s+b+acl+xattrs+sha512
/usr/sbin/augenrules p+i+n+u+g+s+b+acl+xattrs+sha512
NORMAL = FIPSR+sha512
LSPP = FIPSR+sha512
DATAONLY = R+sha512
/etc/gshadow NORMAL
/etc/shadow NORMAL

If any hashes other than "sha512" are present, this is a finding.

Confirm no legacy hashes exist with the following command:

$ sudo grep -iE 'md5|sha1|whirlpool|tiger' /etc/aide.conf | grep -v ^#

If any uncommented lines are returned, this is a finding.

Severity Override Guidance

Verify RHEL 10 AIDE is configured to use FIPS 140-3 file hashing.

Verify global default hash settings with the following command:

$ sudo grep -iE 'sha|md5|rmd' /etc/aide.conf | grep -v ^#
FIPSR = p+i+n+u+g+s+m+ftype+growing+acl+selinux+xattrs+sha512
