Port the bash prototype to a structured, testable Python codebase while
preserving the same control loop and the seven detection signatures. The bash
implementation stays in src/ as the regression oracle.
Highlights:
- enodia_sentinel/ package (stdlib only — no runtime deps):
- detectors/ : one pure function per signature, detect(state, cfg)->Alerts
- system.py : SystemState — one cached /proc + ss snapshot per sweep,
fully injectable so detectors are unit-testable
- daemon.py : sweep loop, in-process cooldown dedup, threaded snapshot
capture, and a SUID filesystem scan moved OFF the loop
thread onto a slow background cadence
- snapshot.py: forensic text + JSON sidecar with per-signature IR guidance
- config.py : dataclass config via TOML + env overrides
- netutil.py : public-IP / CIDR logic via stdlib ipaddress
- tests/ : 25 stdlib-unittest cases (no root, no /proc, no ss needed)
- TOML config, launcher wrapper, Makefile (pip-free install), hardened
systemd unit (env-resolved ExecStart), updated PKGBUILD, rewritten README
Performance: per-sweep cost ~200 ms (shared cached state); the multi-second
SUID walk no longer blocks detection. scandir-based walk replaces os.walk.
Verified on Arch: all 7 detectors fire on red-team drills (reverse_shell,
ld_preload, deleted_exe, new_listener, new_suid confirmed live end-to-end),
no false positives on a clean sweep, 25/25 tests pass.
