A famous quote says 'A book worth reading is worth buying' and this goes well for the textbook entitled Computer Security: Principles and Practice, Second Edition by William Stallings and Lawrie Brown. This second edition builds on the first edition's comprehensive coverage of the field and captures the changes that happened in the area of computer security, including cloud security!
The textbook provides a good examination of security principles, design approaches, standards and real-world examples which fits the bill for both academic and professional audiences. The textbook is divided into five parts, namely: Computer Security Technology and principles, Software Security and Trusted Systems, Management Issues, Cryptographic Algorithms and Network Security.
