Now that Microsoft's systems have been unleashed onto the Internet, they are more vulnerable to attack. This book describes how Microsoft has taken Distributed Computer Environment/Remote Procedure Calls and implemented it over Server Message Block. The author presents Microsoft Developer NT system calls and shows what they look like over the wire.

"The book that Microsoft should have written, but didn't." --Jeremy Allison, Samba Team "Your detailed explanations are clear and backed-up with source code--and the numerous bits of humor make a dry subject very enjoyable to read." --J.D. Lindemann, network engineer, Adaptec, Inc. The first developer's guide to Microsoft(R)'s Internet/Intranet file sharing standard For years, developers and administrators have struggled to understand CIFS, Microsoft's poorly documented standard for Internet file sharing. Finally, there is an authoritative, cross-platform guide to CIFS capabilities and behavior. Implementing CIFS not only delivers the priceless knowledge of a Samba Team member dedicated to investigating the inner workings of CIFS, it also identifies and describes crucial specifications and supporting documents. Provides essential information for designing and debugging large Windows(R) and/or Samba networks Offers clear, in-depth introductions to Server Message Block (SMB), NetBIOS over TCP/IP (NBT), browser services, and authentication Drills down into the internals of CIFS, exposing its behavior on the wire and at the desktop--and its strange quirks Presents illustrative code examples throughout Reflects years of work reviewing obscure documentation, packet traces, and sourcecode Includes the SNIA CIFS Technical Reference Implementing CIFS will be indispensable to every developer who wants to provide CIFS compatibility--and every administrator or security specialist who needs an in-depth understanding of how it really works.

Learn the essentials of Snort 3.0, including installation, configuration, system architecture, and tuning to develop effective intrusion detection and prevention solutions with this easy-to-follow guide Key Features Get to grips with the fundamentals of IDS/IPS and its role in network defense Explore the architecture and key components of Snort 3 and get the most out of them Migrate from Snort 2 to Snort 3 while seamlessly transferring configurations and signatures Purchase of the print or Kindle book includes a free PDF eBook Book DescriptionSnort, an open source intrusion detection and prevention system (IDS/IPS), capable of real-time traffic analysis and packet logging, is regarded as the gold standard in IDS and IPS. The new version, Snort 3, is a major upgrade to the Snort IDS/IPS, featuring a new design and enhanced detection functionality, resulting in higher efficacy and improved performance, scalability, usability, and extensibility. Snort 3 is the latest version of Snort, with the current version at the time of writing being Snort v3.3.3. This book will help you understand the fundamentals of packet inspection in Snort and familiarize you with the various components of Snort. The chapters take you through the installation and configuration of Snort, focusing on helping you fine-tune your installation to optimize Snort performance. You’ll get to grips with creating and modifying Snort rules, fine-tuning specific modules, deploying and configuring, as well as troubleshooting Snort. The examples in this book enable network administrators to understand the real-world application of Snort, while familiarizing them with the functionality and configuration aspects. By the end of this book, you’ll be well-equipped to leverage Snort to improve the security posture of even the largest and most complex networks. What you will learn Understand the key changes in Snort 3 and troubleshoot common Snort 3 issues Explore the landscape of open source IDS/IPS solutions Write new Snort 3 signatures based on new threats and translate existing Snort 2 signatures to Snort 3 Write and optimize Snort 3 rules to detect and prevent a wide variety of threats Leverage OpenAppID for application detection and control Optimize Snort 3 for ideal detection rate, performance, and resource constraints Who this book is for This book is for network administrators, security administrators, security consultants, and other security professionals. Those using other IDSs will also gain from this book as it covers the basic inner workings of any IDS. Although there are no prerequisites, basic familiarity with Linux systems and knowledge of basic network packet analysis will be very helpful.

Scripting has become an enormously popular method of managing and maintaining Windows NT and 2000 networks--as evidenced by the success of Windows NT Shell Scripting, which has sold over 30,000 copies in 2 years. Simpler than programming, yet allowing greater complexity and utility than packaged network management tools, scripting is now the tool of choice by many of you network administrators. Perl is yet another powerful element of the scripting arsenal, yet since it has been ported to the Windows environment, very little information has been published on how to employ this extremely effective tool. Win32 Perl is so powerful that it can accomplish virtually any task that you may want to perform. Dave Roth, prolific creator of Win32 extensions, is prepared to share his unique insight into how these tasks can be accomplished and provide scripts that can be immediately employed. This book illustrates how Perl can automate many current mundane administrative tasks.

User identification and authentication are absolutely essential to modern security. Mechanics of User Identification and Authentication presents the general philosophy of user authentication and access control. Introducing key concepts, this text outlines the process of controlled access to resources through authentication, authorization, and accounting. It provides specific information on the user authentication process for both UNIX and Windows. Addressing more advanced applications and services, the author presents common security models such as GSSAPI and discusses authentication architecture. Each method is presented with a specific authentication scenario.
