Security Cheatsheets is a collection of command reference materials designed for penetration testing, CTF competitions, and security research activities. The project originated from the Ethical Hacking and Penetration Testing course at the University of Florida and expands upon default cheatsheet collections. The cheatsheets focus on tools commonly found in Kali Linux and provide quick reference commands for security professionals who need to recall infrequently used but important commands. The collection covers various security tools including network utilities, exploitation frameworks, and reconnaissance tools. The cheatsheets integrate with the 'cheat' command-line utility and are installed by placing the files in the ~/.cheat/ directory. Users can then access specific tool references by running commands like 'cheat ncat' to display the corresponding cheatsheet. The project includes contributions from multiple security professionals and researchers, with ongoing community involvement. The cheatsheets serve as practical reference materials for security practitioners working in penetration testing, vulnerability assessment, and cybersecurity education environments.
