Book SynopsisPresents the principles, design, development and applications of the Diameter protocol suite The Diameter protocol was born in the Internet Engineering Task Force (IETF) and designed to be a general-purpose Authentication, Authorization, and Accounting (AAA) protocol applicable to many network environments. This book is for everyone who wants to understand the Diameter protocol and its applications. This book explains the place Diameter holds in global telecommunication networks and teaches system architects and designers how to incorporate Diameter into their network environments. Diameter: New Generation AAA Protocol - Design, Practice and Applications begins by describing the foundation of Diameter step-by-step, starting with building blocks of the protocol, and progressing from a simple two-party exchange to a multi-party exchange involving complex routing. It discusses the motivation for using Diameter, talks about its predecessor, RADIUS, and introduces thTable of ContentsDisclaimer xiii About the Authors xv Foreword xvii Preface xix Acknowledgements

Book SynopsisIt is currently quite easy for students or designers/engineers to find very general books on the various aspects of safety, reliability and dependability of computer system architectures, and partial treatments of the elements that comprise an effective system architecture. It is not so easy to find a single source reference for all these aspects of system design. However, the purpose of this book is to present, in a single volume, a full description of all the constraints (including legal contexts around performance, reliability norms, etc.) and examples of architectures from various fields of application, including: railways, aeronautics, space, automobile and industrial automation. The content of the book is drawn from the experience of numerous people who are deeply immersed in the design and delivery (from conception to test and validation), safety (analysis of safety: FMEA, HA, etc.) and evaluation of critical systems. The involvement of real world industrial applications is handled in such as a way as to avoid problems of confidentiality, and thus allows for the inclusion of new, useful information (photos, architecture plans/schematics, real examples).Trade Review"The text is clearly written, well-illustrated, and includes a helpful glossary."

Book SynopsisThis book includes a study of trustworthiness, percentile response time, service availability, and authentication in the networks between users and cloud service providers, and at service stations or sites that may be owned by different service providers. The first part of the book contains an analysis of percentile response time, which is one of the most important SLA (service level agreements) metrics. Effective and accurate numerical solutions for the calculation of the percentile response time in single-class and multi-class queueing networks are obtained. Then, the numerical solution is incorporated in a resource allocation problem. Specifically, the authors present an approach for the resource optimization that minimizes the total cost of computer resources required while preserving a given percentile of the response time. In the second part, the approach is extended to consider trustworthiness, service availability, and the percentile of response time in Web services. These QoS metrics are clearly defined and their quantitative analysis provided. The authors then take into account these QoS metrics in a trust-based resource allocation problem in which a set of cloud computing resources is used by a service provider to host a typical Web services application for single-class customer services and multipleclass customer services respectively. Finally, in the third part of the book a thorough performance evaluation of two notable public key cryptography-based authentication techniques; Public-Key Cross Realm Authentication in Kerberos (PKCROSS) and Public Key Utilizing Tickets for Application Servers (PKTAPP, a.k.a. KX.509/KCA); is given, in terms of computational and communication times. The authors then demonstrate their performance difference using queuing networks. PKTAPP has been proposed to address the scalability issue of PKCROSS. However, their in-depth analysis of these two techniques shows that PKTAPP does not perform better than PKCROSS in a large-scale system. Thus, they propose a new public key cryptography-based group authentication technique. The performance analysis demonstrates that the new technique can scale better than PKCORSS and PKTAPP.Table of ContentsPreface ix Chapter 1. Introduction 1 Chapter 2.

Book SynopsisCybersecurity is more than a buzz word. It is a necessity for every computer system and network on the planet. Hacking is at an all-time high with digital criminals stealing data from governments to technology companies, and everyone in between. Your data may be the next treasure trove of information a hacker wants to get their hands on, and your network may be the next target beaconing vulnerabilities across the internet. History has shown the only effective method at defending a network is to implement a layered security approach with security appliances and applications strategically placed throughout a network. But even some of those methods have failed.Rethinking Cyber Security will give you the background information you need to understand how hackers operate, and the methodologies you can implement to make sure key components of your network are secure. The historic layered approach has been updated to include concepts rarely implemented with out the box solutions that will take network security to the next level. Defense of common attacks are given a new perspective with advice for more stringent controls to limit external and unauthorized access. And technical strategies are explained in simpler terms with examples anyone in the field can understand.You will learn that security does not have to be difficult, overly complicated, or extremely expensive to be effective. Simpler strategies which use already available internet technologies can heighten the security of any network and keep hackers at bay. Practical application is included for key concepts with tips on how to practice new skills in a safe environment. Common poorly figured technologies which give hackers easier access to systems and data are also discussed. Do not worry. Even the most insecure network system can be hardened against an attack when you apply this new information.Table of Contents Chapter 1: History Chapter 2: Paradigm Shift Chapter 3: Traffic Analysis Chapter 4: Vulnerability Assessment Chapter 5: Penetration Testing Chapter 6: Incident Response Evidence Collection Chapter 7: Incident Response Evidence Analysis Chapter 8: Hardening Windows Chapter 9: Hardening Linux Chapter 10: Hardening Network Chapter 11: Cloud Security Chapter 12: Cryptography Appendix 1: Linux Commands Appendix 2: Meterpreter Commands Appendix 3: Common Ports and Protocols

Book SynopsisThis book will help you learn the importance of organizations treating enterprise cyber risk management (ECRM) as a value creator, a business enabler, and a mechanism to create a competitive advantage. Organizations began to see the real value of information and information technology in the mid-1980s. Forty years later, it’s time to leverage your ECRM program and cybersecurity strategy in the same way. The main topics covered include the case for action with specific coverage on the topic of cybersecurity as a value creator, including how the courts, legislators, and regulators are raising the bar for C-suite executives and board members. The book covers how the board’s three primary responsibilities (talent management, strategy, and risk management) intersect with their ECRM responsibilities.ECRM was once solely focused on managing the downside of risk by defending the organization from adversarial, accidental, structural, and environmental threat sources. Author Bob Chaput presents the view that we must focus equally on managing the upside of cyber strengths to increase customer trust and brand loyalty, improving social responsibility, driving revenue growth, lowering the cost of capital, attracting higher quality investments, creating competitive advantage, attracting and retaining talent, and facilitating M&A work. He focuses on the C-suite and board role in the first part and provides guidance on their roles and responsibilities, the most important decision about ECRM they must facilitate, and how to think differently about ECRM funding. You will learn how to the pivot from cost-center thinking to value-center thinking.Having built the case for action, in the second part, the book details the steps that organizations must take to develop and document their ECRM program and cybersecurity strategy. The book first covers how ECRM must be integrated into business strategy. The remainder of that part presents a sample table of contents for an ECRM Program and Cybersecurity Strategy document and works through each section to facilitate development of your own program and strategy. With all the content and ideas presented, you will be able to establish, implement, and mature your program and strategy.What You Will Learn Read new information and treat ECRM and cybersecurity as a value creator Receive updates on legal cases, legislative actions, and regulations that are raising the stakes for organizations, their C-suites, and boards Think differently about funding ECRM and cybersecurity initiatives Understand the most critical ECRM decision that boards must facilitate in their organizations Use practical, tangible, actionable content to develop and document your ECRM program and cybersecurity strategy “This book should be mandatory reading for C-suite executives and board members. It shows you how to move from viewing cybersecurity as a risk to avoid, and a cost center that does not add value and is overhead, to seeing cybersecurity as an enabler and part of your core strategy to transform your business and earn customer and stakeholder trust.” —Paul Connelly, First CISO at the White House and HCA Healthcare Who This Book Is ForThe primary audience includes Chief Information Security Officers, Chief Risk Officers, and Chief Compliance Officers. The secondary audience includes C-suite executives and board members. The tertiary audience includes any stakeholder responsible for privacy, security, compliance, and cyber risk management or students of these topics.Table of Contents

Book SynopsisToday, it's easier for threat actors to simply log in versus hack in. As cyberattacks continue to increase in volume and sophistication, it's not a matter of if, but when, your organization will have an incident. Threat actors target accounts, users, and their associated identitieswhether human or machine, to initiate or progress their attack. Detecting and defending against these malicious activities should be the basis of all modern cybersecurity initiatives. This bookdetails the risks associated with poor identity security hygiene, the techniques that external and internal threat actors leverage, and the operational best practices that organizations should adopt to protect against identity theft, account compromises, and to develop an effective identity and access security strategy. As a solution to these challenges, Identity Security has emerged as a cornerstone of modern Identity and Access Management (IAM) initiatives. Managing accounts, credentials, roles, entitlements, certifications, and attestation reporting for all identities is now a security and regulatory compliance requirement. In this book, you will discover how inadequate identity and privileged access controls can be exploited to compromise accounts and credentials within an organization. You will understand the modern identity threat landscape and learn how role-based identity assignments, entitlements, and auditing strategies can be used to mitigate the threats across an organization's entire Identity Fabric.What You Will LearnUnderstand the concepts behind an identity and how its associated credentials and accounts can be leveraged as an attack vectorImplement an effective identity security strategy to manage identities and accounts based on roles and entitlements, including the most sensitive privileged accountsKnow the role that identity security controls play in the cyber kill chain and how privileges should be managed as a potential weak linkBuild upon industry standards and strategies such as Zero Trust to integrate key identity security technologies into a corporate ecosystemPlan for a successful identity and access security deployment; create an implementation scope and measurable risk reduction; design auditing, discovery, and regulatory reporting; and develop oversight based on real-world strategies to prevent identity attack vectorsWho This Book Is ForManagement and implementers in IT operations, security, and auditing looking to understand and implement an Identity and Access Management (IAM) program and manage privileges in these environments
