====== AIDE (Advanced Intrusion Detection Environment) ======

**AIDE** (Advanced Intrusion Detection Environment) is an Intrusion Detection System (IDS). Which means that AIDE is not a tool to prevent an intrusion but is actually here to report that an intrusion might have happened.

  * AIDE can be used to help track file integrity.
  * AIDE stores a checksum of every file on the system with a choice of several hash methods.
  * Periodically AIDE will compare the snapshot it has against each file to what the file is current reporting.  If there is a difference then the file has changed.

<WRAP info>
**NOTE:**  It is important to update the checksums that AIDE uses every now and then to ensure that they are kept up to date.
