OL07-00-021620 - The Oracle Linux operating system must use a file integrity tool that is configured to use FIPS 140-2 approved cryptographic hashes for validating file contents and directories.
Information
File integrity tools use cryptographic hashes for verifying file contents and directories have not been altered. These hashes must be FIPS 140-2 approved cryptographic hashes.The Oracle Linux operating system installation media ships with an optional file integrity tool called Advanced Intrusion Detection Environment (AIDE). AIDE is highly configurable at install time. This requirement assumes the 'aide.conf' file is under the '/etc' directory.
NOTE: Nessus has provided the target output to assist in reviewing the benchmark to ensure target compliance.
Solution
Configure the file integrity tool to use FIPS 140-2 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.
