- Validate the user is assigned to system in authenticated routes where the user passes in system ID. This protects against a somewhat impractical scenario where an authenticated user cracks a random 15 character alphanumeric ID of a system that doesn't belong to them via web API. - Validate that systemd service exists in database before requesting service details from agent. This protects against authenticated users getting unit properties of services that aren't explicitly monitored. - Refactor responses in authenticated routes to prevent enumeration of other users' random 15 char system IDs.
Beszel
Beszel is a lightweight server monitoring platform that includes Docker statistics, historical data, and alert functions.
It has a friendly web interface, simple configuration, and is ready to use out of the box. It supports automatic backup, multi-user, OAuth authentication, and API access.
Features
- Lightweight: Smaller and less resource-intensive than leading solutions.
- Simple: Easy setup with little manual configuration required.
- Docker stats: Tracks CPU, memory, and network usage history for each container.
- Alerts: Configurable alerts for CPU, memory, disk, bandwidth, temperature, load average, and status.
- Multi-user: Users manage their own systems. Admins can share systems across users.
- OAuth / OIDC: Supports many OAuth2 providers. Password auth can be disabled.
- Automatic backups: Save to and restore from disk or S3-compatible storage.
Architecture
Beszel consists of two main components: the hub and the agent.
- Hub: A web application built on PocketBase that provides a dashboard for viewing and managing connected systems.
- Agent: Runs on each system you want to monitor and communicates system metrics to the hub.
Getting started
The quick start guide and other documentation is available on our website, beszel.dev. You'll be up and running in a few minutes.
