This book review summarizes the book "Principles of Computer Security: CompTIA Security+TM and Beyond" by Wm. Arthur Conklin and Gregory White. The book is aimed at students preparing for the CompTIA Security+ certification exam. It covers a broad range of computer security topics across 25 chapters in less technical detail, in order to cover all of the certification exam objectives. Strengths of the book include its platform-independent conceptual approach and supplementary electronic resources. Weaknesses include the lack of in-depth coverage of any single topic and a logical flow between chapters. The book and its accompanying materials provide a good basic overview of computer security for certification exam preparation.
