Recommended introductory books on computer security include "Maximum Security," "Hacking Exposed," and Matt Bishop's "Computer Security: Art and Science." For a formal introduction, "Introduction to Computer Security" by Goodrich and Tamassia is suggested, as well as Bishop's own introductory text. Understanding computer networks and basic coding skills are essential for deeper learning in security. The SANS framework is highlighted as a simple starting point for understanding security principles, with the NIST Cyber framework recommended as a follow-up. Familiarity with these resources will provide a solid foundation for further exploration in computer security.
