Complete Coverage of Federally Mandated Certification and Accreditation Requirements
C&A is still a nascent science, and although excellent guidance exists on how to evaluate the risk exposure of federal information systems, agencies are still working on improving their C&A programs. C&A is, however, a large endeavor. Although the process has been proven to reduce risk to federal information systems, many folks new to C&A don't know where to start or how to get going on their C&A projects. Seasoned C&A experts continue to look for new ideas on how to improve their existing processes. This book is the first publication with numerous practical examples than can help you step through the C&A process from beginning to end. I wish this book had existed while I was the Security Staff Director of the FDIC so that I could have provided copies to my staff. - from the Foreword by Sunil J. Porter, Former Security Staff Director of the FDIC

Handle, Examine, and Process CD and DVD Evidence for Computer Forensics
CD and DVD Forensics takes the reader through all facets of handling, examining, and processing CD and DVD evidence for computer forensics. At a time when data forensics is becoming a major part of law enforcement and prosecution in the public sector, as well as corporate and system security and integrity in the private sector, the interest in this subject has just begun to blossom.
CD and DVD Forensics is a how-to book that gives the reader tools to open CDs and DVDs in an effort to identify evidence of a crime. These tools can be applied in both the public and private sectors. Armed with this information, readers in law enforcement and corporate security and private investigators will be more effective in performing their evidence-related tasks.

Ethereal Network Protocol Analyzer Toolkit provides the reader with a completely integrated book and companion Web site to analyze network traffic using Ethereal, the world's most popular network protocol analyzer on Windows, Unix, and Apple OS X. This book covers everything from the fundamentals of protocol analysis, to analyzing real world malicious code to programming advanced protocol dissectors. The companion Web site for the book offers dozens of working tools and scripts created for this book. This book provides complete information and step-by-step Instructions for analyzing protocols and network traffic on Windows, Unix or Mac OS X networks. First, readers will learn about the types of sniffers available today and see the benefits of using Ethereal.

Enhancing LAN Performance, Fourth Edition explains how to connect geographically separated LANs with appropriate bandwidth, the issues to consider when weighing the use of multiport or dualport devices, how to estimate traffic for new networks, the effects of configuration changes on the performance of Ethernet and Token Ring networks, the design of switch-based networks that prevent traffic bottlenecks, and other critical topics. It provides the tools to address these issues in relation to specific network requirements. This volume develops mathematical models of various LAN performance issues, enabling LAN managers to determine the answers that are right for their organizations.

This book will take readers from the discovery of vulnerabilities and the creation of the corresponding exploits, through a complete security assessment, all the way through deploying patches against these vulnerabilities to protect their networks. This book is unique in that it details both the management and technical skill and tools required to develop an effective vulnerability management system. Business case studies and real world vulnerabilities are used through the book.
This book starts by introducing the reader to the concepts of a vulnerability management system. Readers will be provided detailed timelines of exploit development, vendors' time to patch, and corporate path installations. Next, the differences between security assessment s and penetration tests will be clearly explained along with best practices for conducting both.

Next, several case studies from different industries will illustrate the effectiveness of varying vulnerability assessment methodologies. The next several chapters will define the steps of a vulnerability assessment including: defining objectives, identifying and classifying assets, defining rules of engagement, scanning hosts, and identifying operating systems and applications.

The next several chapters provide detailed instructions and examples for differentiating vulnerabilities from configuration problems, validating vulnerabilities through penetration testing. The last section of the book provides best practices for vulnerability management and remediation.

Remember the first time someone told you about the OSI model and described the various layers? It's probably something you never forgot. This book takes that same layered approach but applies it to network security in a new and refreshing way. It guides readers step-by-step through the stack starting with physical security and working its way up through each of the seven OSI layers. Each chapter focuses on one layer of the stack along with the attacks, vulnerabilities, and exploits that can be found at that layer. The book even includes a chapter on the mythical eighth layer. It's called the people layer. It's included because security is not just about technology it also requires interaction with people, policy and office politics.
This book is designed to offer readers a deeper understanding of many common vulnerabilities and the ways in which attacker's exploit, manipulate, misuse, and abuse protocols and applications. The authors guide the readers through this process by using tools such as Ethereal (sniffer) and Snort (IDS). The sniffer is used to help readers understand how the protocols should work and what the various attacks are doing to break them. IDS is used to demonstrate the format of specific signatures and provide the reader with the skills needed to recognize and detect attacks when they occur. What makes this book unique is that it presents the material in a layer by layer approach which offers the readers a way to learn about exploits in a manner similar to which they most likely originally learned networking. This methodology makes this book a useful tool to not only security professionals but also for networking professionals, application programmers, and others. All of the primary protocols such as IP, ICMP, TCP are discussed but each from a security perspective. The authors convey the mindset of the attacker by examining how seemingly small flaws are often the catalyst of potential threats. The book considers the general kinds of things that may be monitored that would have alerted users of an attack.

WarDriving and Wireless Penetration Testing brings together the premiere wireless penetration testers to outline how successful penetration testing of wireless networks is accomplished, as well as how to defend against these attacks. As wireless networking continues to spread in corporate and government use, security experts need to become familiar with the methodologies, tools, and tactics used by both penetration testers and attackers to compromise wireless networks and what they can do to both accomplish their jobs as penetration testers and how to protect networks from sophisticated attackers. WarDriving and Wireless Penetration Testing brings together the premiere wireless penetration testers to outline how successful penetration testing of wireless networks is accomplished, as well as how to defend against these attacks.
