ProtoBas aims for everyone to learn network protocols

ProtoBas is a curated collection of network protocols, designed to serve as a reference for offensive and defensive cybersecurity professionals. Inspired by projects like GTFOBins and LOLBAS, ProtoBas aims to provide a structured and searchable database of common (and uncommon) protocols used in computer networks. Each protocol entry includes a brief technical description, default port usage, common behaviors, potential abuse cases, detection strategies, and mitigation techniques.

ProtoBas is an open-source project built with community contributions in mind. If you have suggestions, new protocol entries, or improvements to existing ones, contributions are welcome via pull requests. The project is still in early development and will be regularly updated with new content and features.

Explore the language of the network—one protocol at a time.
