The '''Advanced Intrusion Detection Environment''' ('''AIDE''') was initially developed as a [[free software|free]] replacement for [[Tripwire (company)|Tripwire]] licensed under the terms of the [[GNU General Public License]] (GPL).

The primary developers are named as Rami Lehti and Pablo Virolainen, who are both associated with the [[Tampere University of Technology]], along with Richard van den Berg, an independent [[Netherlands|Dutch]] security consultant. The project is used on many [[Unix-like]] systems as an inexpensive [[baseline (configuration management)|baseline]] control and [[rootkit]] detection system.

==How it worksFunctionality==

WhatAIDE Aide basically does is taketakes a "snapshot" of the state of the system, register hashes, modification times, and other data regarding the files defined by the administrator. This "snapshot" is used to build a database that is saved and (usually)may be stored inon an external device for safekeeping.

When the administrator wants to run an integrity test, hethe administrator places the previously built database in an accessible place and commands AideAIDE to compare the database against the real status of the system. Should a change have happened to the computer between the snapshot creation and the test, AideAIDE will detect it and report it to the administrator. Alternatively, AIDE can be configured to run on a schedule and report changes daily using scheduling technologies such as [[cron]], which is the default behavior of the [[Debian]] AIDE package.<ref>{{cite web|title=Using Aide on Ubuntu 12.04 LTS (Precise Pangolin) and Debian 7 (Wheezy)|url=http://www.snekul.com/wordpress/blog/2012/09/27/using-aide-on-ubuntu-12-04-lts-precise-pangolin-and-debian-7-wheezy/|archive-url=https://web.archive.org/web/20130109055116/http://www.snekul.com/wordpress/blog/2012/09/27/using-aide-on-ubuntu-12-04-lts-precise-pangolin-and-debian-7-wheezy/|url-status=dead|archive-date=9 January 2013|accessdate=12 March 2013}}</ref>

This is mainly useful for security purposes, given that any malicious change which could have happened inside of the system would be reported by AideAIDE.
