CDXE
CDXE is an all-in-one internet-like environment designed for smaller scale Cyber Defence Exercises. It addresses the time and resource demands of preparing realistic exercise setups by simplifying the creation of the internet portion of such environments.
The tool includes support for internet routers, routing, root name servers, and additional components. It emphasizes easy environment setups, live modifications during exercises, and low resource usage. Users connect local environments either through static connections or by peering with CDXE using BGP, with both IPv4 and IPv6 supported. Deployment occurs as a single statically compiled binary. An example configuration generator is built in, and the generated examples include a README along with a WireGuard configuration file that routes all network traffic into the simulated environment.
Installation requires a supported version of Go, after which the binary is obtained by running go install kryptogram.se/cdxe@latest. The environment is started with a command that loads backbone and endpoint configuration files produced by the generator. It functions as a specialized exercise environment for cyber defence training scenarios.
