OverTheWire
Free SSH-based wargames teaching Linux, networking, and security fundamentals level by level.
Technical Architecture & Overview
OverTheWire runs wargames such as Bandit, Natas, and Narnia, where players connect over SSH (or, for Natas, a browser) and solve challenges that teach command-line skills, web security, and exploitation in sequence. The games are free and community run, with Bandit aimed at absolute beginners. Level 0 credentials are published on the site, and finishing each level gives the login for the next one.
Targeted Technical Use Cases
Building Linux command-line and security fundamentals through self-paced, mostly terminal-based challenges.
Evaluation & Trade-offs
Core Strengths
