FINT-4402 - Usage of SHA256/SHA512 in AIDE configuration


This check found that SHA256 or SHA512 were not used to create hashes of files.


File Integrity

How to solve

Consider using strong hashing algorithms in your AIDE configuration. MD5 and SHA1 are considered fairly weak, and hash collisions might result. This means that two different files end up in displaying the same hash. As AIDE has the focus on monitoring file integrity, strong algorithms should be used.

Perform daily health checks of your environment, learn in-depth system hardening, and protect your systems better.
