Many companies have been continuously fighting threats posed by hacker groups. However, keeping security technologies rapidly evolving to match increasingly complex threats remains a challenge, even if we believe it is the best time. The growing focus on security has left IT managers overwhelmed, as they urgently need expert experience to implement complex, multi-layered solutions. This book covers various topics in network security, helping readers gain a foundational understanding of the components of a network security architecture and how to implement them for maximum effectiveness. The book presents topics directly and clearly, showcasing the features, mechanisms, and functions of various network security devices. Through a series of case studies, it demonstrates concepts and their practical applications in real-world scenarios. Whether you want to understand the basic principles and practical guidelines of network security or seek references for security configurations, this book provides sufficient guidance to help you effectively protect valuable company resources.
The book comprehensively introduces various fundamental concepts related to network security, helping readers fully understand the key technologies and tools required to ensure network security, including software and hardware implementations. The logical structure of the book is very clear, divided into four parts:
Part 1 introduces foundational knowledge, including numerous terms and concepts, serving as the cornerstone for entering the field of security;
Part 2 introduces the two major components of security: cryptography and security policies, which are essential factors in building secure systems;
Part 3 covers various security components, including web security, router security, firewalls, intrusion detection systems, remote access security, VPNs, PKI, wireless security, logging, and auditing;
Part 4 is the appendix.
This book is suitable for readers such as network or system administrators, network engineers, and network designers. Additionally, it is suitable for IT managers responsible for product and strategy decisions. It is also applicable to students in related fields and professionals seeking to enter the IT industry.
