It defines the important stages of penetration testing: reconnaissance, threat modeling, vulnerability analysis, exploitation, and post-exploitation practices. Emphasizing practicality, the chapter combines ethical and legal compliance with best practices and common mistakes. It also emphasizes the need of strategic remedial planning, good documentation, and correspondence with stakeholders. The chapter is a useful manual for cybersecurity experts by outlining several tools and approaches suitable for every phase. Eventually, by means of methodical, repeatable, and responsible penetration testing procedures, the material helps to build strong security postures.</jats:p>
