How to install AIDE on Ubuntu 22.04?

Overview

The Advanced Intrusion Detection Environment, often known as AIDE, is used to improve the security of your system. This Unix-based utility keeps an eye on the system to spot any unauthorized changes.

File properties like ownership, checksums, permissions, etc. are compiled into a database by AIDE. AIDE routinely examines the database when it is created in accordance with the status of the file system to spot irregularities. AIDE notifies the user or administrator of any issues and urges them to act right away. As a result, it finds issues before compromising any system components.
