Defensive Security Handbook

Despite the increase of high-profile hacks, record-breaking data leaks, and ransomware attacks, many organizations don’t have the budget to establish or outsource an information security (InfoSec) program, forcing them to learn on the job. For companies obliged to improvise, this pragmatic guide provides a security-101 handbook with steps, tools, processes, and ideas to help you drive maximum-security improvement at little or no cost. Each chapter in this book provides step-by-step instructions for dealing with a specific issue, including breaches and disasters, compliance, network infrastructure and password management, vulnerability scanning, and penetration testing, among others. Network engineers, system administrators, and security professionals will learn tools and techniques to help improve security in sensible, manageable chunks. Learn fundamentals of starting or redesigning an InfoSec program Create a base set of policies, standards, and procedures Plan and design incident response, disaster recovery, compliance, and physical security Bolster Microsoft and Unix systems, network infrastructure, and password management Use segmentation practices and designs to compartmentalize your network Explore automated process and tools for vulnerability management Securely develop code to reduce exploitable errors Understand basic penetration testing concepts through purple teaming Delve into IDS, IPS, SOC, logging, and monitoring

An immersive learning experience enhanced with technical, hands-on labs to understand the concepts, methods, tools, platforms, and systems required to master the art of cybersecurity Key FeaturesGet hold of the best defensive security strategies and toolsDevelop a defensive security strategy at an enterprise levelGet hands-on with advanced cybersecurity threat detection, including XSS, SQL injections, brute forcing web applications, and moreBook Description Every organization has its own data and digital assets that need to be protected against an ever-growing threat landscape that compromises the availability, integrity, and confidentiality of crucial data. Therefore, it is important to train professionals in the latest defensive security skills and tools to secure them. Mastering Defensive Security provides you with in-depth knowledge of the latest cybersecurity threats along with the best tools and techniques needed to keep your infrastructure secure. The book begins by establishing a strong foundation of cybersecurity concepts and advances to explore the latest security technologies such as Wireshark, Damn Vulnerable Web App (DVWA), Burp Suite, OpenVAS, and Nmap, hardware threats such as a weaponized Raspberry Pi, and hardening techniques for Unix, Windows, web applications, and cloud infrastructures.

The Routledge Handbook of Defence Studies provides a comprehensive collection of essays on contemporary defence studies by leading international scholars. Defence studies is a multi-disciplinary study of how agents, predominantly states, prepare for and go to war. Whereas security studies has been broadened and stretched to cover at times the near totality of international and domestic affairs, and war studies has come to mean not just operations and tactics but also experiences and outcomes, defence studies remains a coherent area of study primarily aimed at how defence policy changes over time and in relation to stimulating factors such as alterations in power, strategy and technology. This new Handbook offers a complete landscape of this area of study and contributes to a review of defence studies in terms of policy, security and war, but also looks forward to new challenges to existing conceptions of defence and how this is changing as states and their militaries also change. The volume is divided into four thematic sections: Defence as Policy; Defence Practice; Operations and Tactics; and Contemporary Defence Issues. The ability to review the field while also looking forward to further research is an important element of a sustainable text on defence studies. In as much as this volume is able to highlight the main themes of defence studies, it also offers an in-depth look into how defence issues can be examined and compared in a contemporary setting. This Handbook will be of great interest to students of defence studies, strategic studies, war studies, security studies and IR.

This handbook reveals those aspects of hacking least understood by network administrators. It analyzes subjects through a hacking/security dichotomy that details hacking maneuvers and defenses in the same context. Chapters are organized around specific components and tasks, providing theoretical background that prepares network defenders for the always-changing tools and techniques of intruders. Part I introduces programming, protocol, and attack concepts. Part II addresses subject areas (protocols, services, technologies, etc.) that may be vulnerable. Part III details consolidation activities that hackers may use following penetration.
