Autonomous Intelligent Cyber Defense Agent (Aica): A Comprehensive Guide

This book offers a structured overview and a comprehensive guide to the emerging field of Autonomous Intelligent Cyber Defense Agents (AICA). The book discusses the current technical issues in autonomous cyber defense and offers information on practical design approaches. The material is presented in a way that is accessible to non-specialists, with tutorial information provided in the initial chapters and as needed throughout the book. The reader is provided with clear and comprehensive background and reference material for each aspect of AICA.

Today's cyber defense tools are mostly watchers. They are not active doers. They do little to plan and execute responses to attacks, and they don't plan and execute recovery activities. Response and recovery - core elements of cyber resilience - are left to human cyber analysts, incident responders and system administrators. This is about to change. The authors advocate this vision, provide detailed guide to how such a vision can be realized in practice, and its current state of the art.

This book also covers key topics relevant to the field, including functional requirements and alternative architectures of AICA, how it perceives and understands threats and the overall situation, how it plans and executes response and recovery, how it survives threats, and how human operators deploy and control AICA. Additionally, this book covers issues of testing, risk, and policy pertinent to AICA, and provides a roadmap towards future R&D in this field.

This book targets researchers and advanced students in the field of cyber defense and resilience. Professionals working in this field as well as developers of practical products for cyber autonomy will also want to purchase this book.

本書提供了對自主智能網絡防禦代理（AICA）這一新興領域的結構性概述和全面指南。本書討論了自主網絡防禦的當前技術問題，並提供了實用的設計方法信息。本書以非專業人士易於理解的方式呈現材料，並在初始章節和需要時提供教程信息。對於AICA的每個方面，讀者都能獲得清晰而全面的背景和參考資料。

如今的網絡防禦工具大多是監視者，它們不是主動執行者。它們對攻擊的響應和恢復活動的規劃和執行很少。響應和恢復是網絡韌性的核心要素，這些工作通常由人類網絡分析師、事件響應人員和系統管理員來完成。然而，這種情況即將改變。作者們提倡這一願景，並提供了如何在實踐中實現這一願景以及其目前的最新技術指南。

本書還涵蓋了與該領域相關的關鍵主題，包括AICA的功能要求和替代架構，它如何感知和理解威脅和整體情況，如何規劃和執行響應和恢復，如何應對威脅，以及人類操作員如何部署和控制AICA。此外，本書還涵蓋了與AICA相關的測試、風險和政策問題，并提供了未來研發的路線圖。

本書面向網絡防禦和韌性領域的研究人員和高級學生。從事該領域工作的專業人士以及開發網絡自主產品的開發人員也會希望購買本書。

Dr. Alexander Kott serves as the Chief Scientist of the U.S. Combat Capabilities Development Command Army Research Laboratory. In this role he provides leadership in development of ARL technical strategy, maintaining technical quality of ARL research, and representing ARL to the external technical community. Dr. Kott is also the Army Senior Research Scientist (ST) for Cyber Resilience, in which capacity he formulates the vision of future technologies critical to the Army cyber resilience, and advocates and shapes plans and programs leading to such technologies. Prior to becoming the Chief Scientist of ARL, Dr. Kott was the Chief of the Network Science Division at ARL, leading a division focused on innovative basic and applied research, threat analysis, technology transition and security operations in computer, communications, information, and social networks; formulating and executing a broad range of internal and extramural research programs. Earlier, Dr. Kott served as a Program Manager at Defense Advanced Research Projects Agency (DARPA), where he was responsible for management of multiple, large-scale R&D projects. Kott's earlier positions included Director of Research and Development at Carnegie Group, Pittsburgh, PA. There, his work focused on novel information technology approaches, such as Artificial Intelligence, to complex problems in engineering design, and planning and control in manufacturing, telecommunications and aviation industries. Dr. Kott earned his PhD in Mechanical Engineering from the University of Pittsburgh, Pittsburgh, PA, in 1989, where he researched AI approaches to invention of complex systems. He received the Secretary of Defense Exceptional Public Service Award, in October 2008. He published over 100 technical papers and served as the co-author and editor of twelve books.

亞歷山大·科特博士擔任美國陸軍戰鬥能力發展指揮部陸軍研究實驗室的首席科學家。在這個職位上，他負責制定ARL技術戰略的領導，維護ARL研究的技術質量，並代表ARL與外部技術社群互動。科特博士還擔任陸軍資訊安全的高級研究科學家，他制定了與陸軍資訊安全相關的未來技術願景，並倡導和塑造相應的計劃和項目。在擔任ARL首席科學家之前，科特博士是ARL網絡科學部門的主管，領導該部門進行創新的基礎和應用研究、威脅分析、技術轉化和計算機、通信、信息和社交網絡的安全運營；制定和執行各種內部和外部研究計劃。早些時候，科特博士在國防高級研究計劃局（DARPA）擔任項目經理，負責管理多個大規模的研發項目。科特博士之前的職位還包括匹茲堡卡內基集團的研發總監，他在那裡的工作主要集中在工程設計、製造、電信和航空等行業中，利用人工智能等新穎的信息技術方法解決複雜問題。科特博士於1989年在匹茲堡大學獲得機械工程博士學位，他的研究方向是利用人工智能方法創造複雜系統。他於2008年獲得國防部傑出公共服務獎，並發表了100多篇技術論文，並擔任12本書的合著者和編輯。
