One of the most compelling problems of the Internet is the lack of a comprehensive and unifying approach to dealing with service security and resilience. Although many such individual reliability mechanisms exist, no general set of policies or standards exists regarding how these mechanisms can be combined to achieve an overall robust state of security for the network.Network Availability for Internet Services: Threats and Defenses introduces solutions for defending against distributed denial of service (DDoS) attacks. This book proposes and evaluates practical mechanisms that will frustrate these attacks, and protect a wide range of services while maintaining or even improving their performance characteristics. The focus is on network-level faults and attacks. This book provides a practical end-to-end framework that significantly improves service availability and connectivity, without incurring a prohibitive deployment or performance cost. It also introduces and analyzes mechanisms that boost the security, resilience, and performance of network systems in a manner that is transparent to both the existing infrastructure and the end-users.Designed for advanced-level students in computer science as a secondary text or reference book, this book is also suitable for practitioners and researchers in industry, as well as the government and military.

This book offers a unique and timely contribution to the intersection of agentic AI, reliability engineering, and system trustworthiness. This book addresses both sides of the reliability challenge: how to ensure the reliability of agentic AI systems (with autonomy, planning, and goal-directed behavior), and how agentic AI can be used to enhance the reliability of critical infrastructure and industrial systems (e.g., energy, transportation, manufacturing). It introduces a layered architectural framework that connects technical design (models, execution, cognition) with system-level trust and explainability. This book outlines how awareness and transparency can be engineered into each layer, supporting dependable human-AI collaboration. Beyond technical detail, the book helps researchers, practitioners, and policymakers understand both the barriers and enabling factors for adopting agentic AI in real-world reliability-critical domains. It draws on examples from sectors like power systems, autonomous transportation, and predictive maintenance. This book includes a survey and critical analysis of the current state of regulatory frameworks and standards organizations (e.g., IEEE, ISO, EU AI Act), highlighting gaps and aligning recommendations with the evolving compliance landscape. This book provides an interdisciplinary bridge between AI development, systems reliability engineering, and AI policy/ethics communities—making it relevant for a wide audience across academia, industry, and regulatory bodies.

This book constitutes the proceedings of the 17th International Symposium on Research in Attacks, Intrusions and Defenses, RAID 2014, held in Gothenburg, Sweden, in September 2014. The 22 full papers were carefully reviewed and selected from 113 submissions, and are presented together with 10 poster abstracts. The papers address all current topics in computer security, including network security, authentication, malware, intrusion detection, browser security, web application security, wireless security, vulnerability analysis.
