File Integrity Monitor Windows Service

Project roadmap

1. 01

   Build the baseline hash snapshot

   ~1.5h

   Walk watched directories and compute SHA256 hashes for all files, storing them as a baseline.

2. 02

   Set up FileSystemWatcher event handlers

   ~2h

   Wire up Created, Changed, Deleted, and Renamed events for the watched directories.

3. 03

   Implement change verification against baseline

   ~2h

   On each event, recompute the file's hash and compare against the baseline to confirm a real content change.

4. 04

   Add structured logging of integrity events

   ~1.5h

   Log each detected change with timestamp, path, and change type to a rolling log file.

5. 05

   Package as a Worker Service / Windows Service

   ~2h

   Configure the app as a .NET Worker Service that can be installed and run as a Windows Service.

6. 06

   Add configuration for watched paths

   ~1h

   Support an appsettings.json list of directories and exclude patterns to monitor.
