Original: 🔒 Inside ATLOCK v4: Building a Windows Security Suite Beyond Simple Password Protection

Short summary

ATLOCK v4 is a Python-based Windows security suite that goes beyond simple password protection by combining NTFS ACL modification, Fernet AES encryption with PBKDF2 key derivation, event-driven intrusion detection with photo/video capture, and forensic logging. The project is an exploration of layered desktop security rather than an enterprise product.

  • •Combines NTFS ACLs, AES encryption, intrusion detection, and forensic logging in one app
  • •Uses PBKDF2-HMAC-SHA256 with 200K iterations for key derivation
  • •Event-driven escalation captures photos and videos on failed authentication
