This best-selling guide provides a complete, practical, up-to-date introduction to network and computer security. SECURITY+ GUIDE TO NETWORK SECURITY FUNDAMENTALS, Fifth Edition, maps to the new CompTIA Security+ SY0-401 Certification Exam, providing thorough coverage of all domain objectives to help readers prepare for professional certification and career success. The text covers the essentials of network security, including compliance and operational security; threats and vulnerabilities; application, data, and host security; access control and identity management; and cryptography. The extensively updated Fifth Edition features a new structure based on major domains, a new chapter dedicated to mobile device security, expanded coverage of attacks and defenses, and new and updated information reflecting recent developments and emerging trends in information security, such as virtualization. New hands-on and case activities help readers review and apply what they have learned, and end-of-chapter exercises direct readers to the Information Security Community Site for additional activities and a wealth of learning resources, including blogs, videos, and current news and information relevant to the information security field.
My exam date for the Security+ exam is coming up soon in a couple of days, and the two books which I found the most accessible and useful were the security+ book for the SY0-401 exam by Emmett Dulaney and this book. Though this particular edition is for the previous version (SY0-301),it complemented the former book incredibly well and would recommend this only as a supplement.
I took this as part of an online course through Cengage. The textbook is well structured and provides a breadth overview of Security concerns. The labs had a tendency to overly rehash the material or go completely off target from the chapter material it is included in.
