Download Free Authentication Systems For Secure Networks Book in PDF and EPUB Free Download. You can read online Authentication Systems For Secure Networks and write the review.

This unique book explores the use of cryptographic techniques in authentication and key distribution systems. Systems such as Kerberos, NetSP, SPX, TESS, and SESAME are analyzed and compared. Computer scientists, electrical engineers, networking specialists, and information technology professionals learn valuable cryptographic techniques--and why authentication and key distribution systems are likely to become the primary means for securing networks and distributed systems in the future.
Reid (senior product manager, Cryptometrics) introduces the technical capabilities and limitations of computer biometric systems for measuring fingerprints, eye characteristics, or other body information as a computer security measure serving a similar purpose to personal identification numbers. He describes the workings of the different types of technologies and examines some of the mathematics behind biometric systems. He also describes the conceptualization and implementation of a particular system with which he was involved. Annotation : 2004 Book News, Inc., Portland, OR (booknews.com).
Describes tools of e-security and a range of applications, including recently developed technologies like Trust management systems and biometrics-based security.
PART OF THE NEW JONES & BARTLETT LEARNING INFORMATION SYSTEMS SECURITY & ASSURANCE SERIES! Access control protects resources against unauthorized viewing, tampering, or destruction. They serve as a primary means of ensuring privacy, confidentiality, and prevention of unauthorized disclosure. The first part of Access Control, Authentication, and Public Key Infrastructure defines the components of access control, provides a business framework for implementation, and discusses legal requirements that impact access contol programs. It then looks at the risks, threats, and vulnerabilities prevalent in information systems and IT infrastructures and how to handle them. The final part is a resource for students and professionals which disucsses putting access control systems to work as well as testing and managing them.
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
AAA (Authentication, Authorization, Accounting) describes a framework for intelligently controlling access to network resources, enforcing policies, and providing the information necessary to bill for services. AAA and Network Security for Mobile Access is an invaluable guide to the AAA concepts and framework, including its protocols Diameter and Radius. The authors give an overview of established and emerging standards for the provision of secure network access for mobile users while providing the basic design concepts and motivations. AAA and Network Security for Mobile Access: Covers trust, i.e., authentication and security key management for fixed and mobile users, and various approaches to trust establishment. Discusses public key infrastructures and provides practical tips on certificates management. Introduces Diameter, a state-of-the-art AAA protocol designed to meet today’s reliability, security and robustness requirements, and examines Diameter-Mobile IP interactions. Explains RADIUS (Remote Authentication Dial-In User Services) and its latest extensions. Details EAP (Extensible Authentication Protocol) in-depth, giving a protocol overview, and covering EAP-XXX authentication methods as well as use of EAP in 802 networks. Describes IP mobility protocols including IP level mobility management, its security and optimizations, and latest IETF seamless mobility protocols. Includes a chapter describing the details of Mobile IP and AAA interaction, illustrating Diameter Mobile IP applications and the process used in CDMA2000. Contains a section on security and AAA issues to support roaming, discussing a variety of options for operator co-existence, including an overview of Liberty Alliance. This text will provide researchers in academia and industry, network security engineers, managers, developers and planners, as well as graduate students, with an accessible explanation of the standards fundamental to secure mobile access.
