LogSentry/
Lightweight log detection engine (mini-SIEM) that parses auth logs into normalized events and runs YAML detection rules over them — SSH brute-force, credential compromise, privilege-escalation attempts. Sliding-window and sequence correlation built from scratch, with terminal/JSON/SQLite reporting and a CI-friendly exit mode.
File Integrity Monitor/
Windows desktop security app that fingerprints critical files with SHA-256 and flags anything modified, added, or deleted. Baselines are HMAC tamper-sealed so they can't be silently edited, with scheduled scans, email alerts, and CSV/JSON reporting — pure Python stdlib, ships as a single .exe.
