Main Screen

In this project I have designed a basic IDS (Intrusion Detection System) which will recognize any modification to a file. We assume that the files can be modified by an attacker. The file can be in binary or text format.

The application may ask user to provide a folder name for scanning.

if any of the files of the target folder has been modified, application will give an alert like "changed" for the modified ones.
