NetBox

NetBox at a glance

NetBox is the widely used open-source source of truth for network infrastructure — IPAM and DCIM documenting IP space, devices, cabling and more. NetBox ships regular releases plus security fixes; as a web application holding a detailed map of the network (and often credentials), hardening and timely updates matter.

For admins updates run through the documented procedure and include database migrations — back up the PostgreSQL database first, and read the release notes, since plugins are the usual compatibility stumbling block and the required Python/PostgreSQL versions move over time. Keep NetBox off the open internet behind authentication and TLS, since its data would be valuable to an attacker. After upgrading, verify login, the data model and any plugins and integrations (it's often the backbone of automation). Track the version and its support window; patchletter surfaces new NetBox releases so security fixes aren't missed.
