# Security Alert Center (SAC)
Self-hosted hub for security events from Linux and Windows agents: ingest, correlation, UI, notifications, host management.
**Русский:** [README.md](README.md)
## Repositories
| Repository | Role |
|------------|------|
| [ssh-monitor](https://git.kalinamall.ru/PapaTramp/ssh-monitor) | Linux agent |
| [RDP-login-monitor](https://git.kalinamall.ru/PapaTramp/RDP-login-monitor) | Windows agent |
| **security-alert-center** | SAC server (Ubuntu 24.04) |
| [seaca](https://git.kalinamall.ru/PapaTramp/seaca) | Android client |
**Version:** `0.4.11` · **Deploy:** `sudo /opt/sac-deploy.sh`
## Features
- **Ingest** from agents ([contract](docs/agent-integration.md)): SSH/sudo/logind, RDP/RDG/WinRM/SMB, heartbeat, reports, inventory
- **Problems** — auto-correlation (incl. RDG 302→303 flap within 110 s)
- **Notifications** — Telegram, email, webhook, FCM (Seaca)
- **Web UI** — events, hosts, problems, reports, dashboard (SSE), settings (admin)
- **RDG flap** — badge on 302/303 events, **qwinsta/logoff** via WinRM to client PC (domain admin required); optional auto-disconnect of stuck sessions
- **Hosts** — agent status, inventory, agent updates (SSH/WinRM); WinRM RDP: SAC fetches from git, client downloads zip from SAC, runs local `Deploy-LoginMonitor.ps1` (no git on PC)
- **Mobile** — enrollment, devices, push; Seaca: ack/resolve, qwinsta/logoff via SAC API
- **Roles** — `admin` / `monitor`
