Security in Computing

Written by Charles P. Pfleeger, Shari Lawrence Pfleeger, and Jonathan Margulies, the textbook Security in Computing, 5th Edition delivers a foundational treatment of computer security principles and system protection. The work addresses fundamental requirements in computer security instruction by establishing how protective measures apply across technical environments.

The content organizes threat analysis and protective strategies across six primary operational domains: users, software, physical devices, operating systems, networks, and data. Detailed thematic coverage includes computer security fundamentals, user authentication procedures, malicious code prevention techniques, cryptography and encryption applications, firewall implementations, and intrusion detection mechanisms.

To support coursework, the volume includes over two hundred chapter-ending exercises that help students reinforce their grasp of technical concepts. This structure provides targeted utility for students preparing for technical careers, as well as practicing IT professionals and security professionals seeking an authoritative reference.
