Dead Man's Switch + USB Kill Switch for Linux - Open source defensive security project

Sharing a project I've been building for the community: a defensive security toolkit for Linux focused on physical server protection.

It includes:

USB kill switch — if the device is unplugged, LUKS keys are wiped and the system reboots

Dead man's switch — no heartbeat in 24h triggers wipe and reboot

Web-based manual kill switch with token authentication

USBGuard-based USB device control via web UI

Designed to run on a private network (Tailscale), with Discord notifications.

Feedback, PRs and criticism welcome, especially if you spot anything worth improving in the security model.
