A revolutionary, soups-to-nuts approach to network security from two of Microsoft's leading security experts.

The perimeter defenses guarding your network perhaps are not as secure as you think. Hosts behind the firewall have no defenses of their own, so when a host in the "trusted" zone is breached, access to your data center is not far behind. That’s an all-too-familiar scenario today. With this practical book, you’ll learn the principles behind zero trust architecture, along with details necessary to implement it. The Zero Trust Model treats all hosts as if they’re internet-facing, and considers the entire network to be compromised and hostile. By taking this approach, you’ll focus on building strong authentication, authorization, and encryption throughout, while providing compartmentalized access and better operational agility. Understand how perimeter-based defenses have evolved to become the broken model we use today Explore two case studies of zero trust in production networks on the client side (Google) and on the server side (PagerDuty) Get example configuration for open source tools that you can use to build a zero trust network Learn how to migrate from a perimeter-based network to a zero trust network in production

Unlike data communications of the past, today's networks consist of numerous devices that handle the data as it passes from the sender to the receiver. However, security concerns are frequently raised in circumstances where interconnected computers use a network not controlled by any one entity or organization. Introduction to Network Security exam

An introduction to a range of cyber security issues explains how to utilize graphical approaches to displaying and understanding computer security data, such as network traffic, server logs, and executable files, offering guidelines for identifying a network attack, how to assess a system for vulnerabilities with Afterglow and RUMINT visualization software, and how to protect a system from additional attacks.

Network Tutorial delivers insight and understanding about network technology to managers and executives trying to get up to speed or stay current with the complex challenges of designing, constructing, maintaining, upgrading, and managing the netwo

We live in a wired society, with computers containing and passing around vital information on both personal and public matters. Keeping this data safe is of paramount concern to all. Yet, not a day seems able to pass without some new threat to our computers. Unfortunately, the march of technology has given us the benefits of computers and electronic tools, while also opening us to unforeseen dangers. Identity theft, electronic spying, and the like are now standard worries. In the effort to defend both personal privacy and crucial databases, computer security has become a key industry. A vast array of companies devoted to defending computers from hackers and viruses have cropped up. Research and academic institutions devote a considerable amount of time and effort to the study of information systems and computer security. Anyone with access to a computer needs to be aware of the developing trends and growth of computer security. To that end, this book presents a comprehensive and carefully selected bibliography of the literature most relevant to understanding computer security. Following the bibliography section, continued access is provided via author, title, and subject indexes. With such a format, this book serves as an important guide and reference tool in the defence of our computerised culture.

Comprehensive in approach, this introduction to network and internetwork security provides a tutorial survey of network security technology, discusses the standards that are being developed for security in an internetworking environment, and explores the practical issues involved in developing security applications.

Keeping up with the latest developments in cyber security requires ongoing commitment, but without a firm foundation in the principles of computer security and digital forensics, those tasked with safeguarding private information can get lost in a turbulent and shifting sea. Providing such a foundation, Introduction to Security and Network Forensics covers the basic principles of intrusion detection systems, encryption, and authentication, as well as the key academic principles related to digital forensics. Starting with an overview of general security concepts, it addresses hashing, digital certificates, enhanced software security, and network security. The text introduces the concepts of risk, threat analysis, and network forensics, and includes online access to an abundance of ancillary materials, including labs, Cisco challenges, test questions, and web-based videos. The author provides readers with access to a complete set of simulators for routers, switches, wireless access points (Cisco Aironet 1200), PIX/ASA firewalls (Version 6.x, 7.x and 8.x), Wireless LAN Controllers (WLC), Wireless ADUs, ASDMs, SDMs, Juniper, and much more, including: More than 3,700 unique Cisco challenges and 48,000 Cisco Configuration Challenge Elements 60,000 test questions, including for Certified Ethical Hacking and CISSP® 350 router labs, 180 switch labs, 160 PIX/ASA labs, and 80 Wireless labs Rounding out coverage with a look into more advanced topics, including data hiding, obfuscation, web infrastructures, and cloud and grid computing, this book provides the fundamental understanding in computer security and digital forensics required to develop and implement effective safeguards against ever-evolving cyber security threats. Along with this, the text includes a range of online lectures and related material, available at: http://asecuritybook.com.
