Book Description

In these days of high-profile hacking, server security is no less important than securing your application or network. In addition many companies must comply with government security regulations. No matter how secure your application is, your business is still at risk if your server is vulnerable. Here is how you solve your WebSphere server security worries in the best possible way.

This tutorial is focused towards ways in which you can avoid security loop holes. You will learn to solve issues that can cause bother when getting started with securing your IBM WebSphere Application Server v7.0 installation. Moreover, the author has documented details in an easy-to-read format, by providing engaging hands-on exercises and mini-projects.

The book starts with an in-depth analysis of the global and administrative security features of WebSphere Application Server v7.0, followed by comprehensive coverage of user registries for user authentication and authorization information. Moving on you will build on the concepts introduced and get hands-on with a mini project. From the next chapter you work with the different front-end architectures of WAS along with the Secure Socket Layer protocol, which offer transport layer security through data encryption.

You learn user authentication and data encryption, which demonstrate how a clear text channel can be made safer by using SSL transport to encrypt its data. Download Now »

Book Description

BlackBerry Enterprise Server (BES) is a platform that extends corporate messaging and collaboration services to BlackBerry devices. It supports management and administration of devices, and also supports deployment of third-party applications on the BlackBerry device platform. The basics of installing BlackBerry Enterprise Server are familiar for most administrators, but the server is infinitely configurable and contains extended administration features.

This book focuses on BlackBerry Enterprise Server for Microsoft Exchange, providing detailed information on planning and implementing a BlackBerry Enterprise Server deployment. It will show you how to use the BES to manage the flow of e-mail data ensuring that it is directed to its ultimate destination – the BlackBerry Smartphone. It covers all the new features of the BES version 5.0 and also looks at areas that have been enhanced from the previous versions. If you are new to BlackBerry Enterprise Server, this is the perfect guide to help with your planning and deployment.

BlackBerry Enterprise Server supports a variety of messaging platforms, including Microsoft Exchange, IBM Lotus Domino, and Novell GroupWise. As you begin reading this book you will first learn about the two prominent features introduced with BES 5: BlackBerry Administration Service Console and Server Routing Protocol. As you proceed further you will learn about 200 more configurable IT Policies provided by BES 5 as opposed to the earlier versions. We will look at Mobile Data Service and third-party applications that can be deployed to BlackBerry devices. We will also look at a monitoring portal included in the installation process of BES 5, which provides health scores to check the BES performance and a much more stable and robust SNMP.

Book Description

Many systems administrators on the Mac need a way to manage machine configuration after initial setup and deployment. Apple’s Managed Preferences system (also known as MCX) is under-documented, often misunderstood, and sometimes outright unknown by sys admins. MCX is usually deployed in conjunction with an OS X server, but it can also be used in Windows environments or where no dedicated server exists at all.

Enterprise Mac Managed Preferences is the definitive guide to Apple’s Managed Client technology. With this book, you’ll get the following:

• An example-driven guide to Mac OS X Managed Preferences/Client technology
• Recipes for common use case studies and patterns
• A targeted approach appropriate for any sys admin that manages Macs in an OS X or Windows environment

This is the only book that focuses on this facet of OS X exclusively. If you’re a sys admin, this book will take away much of the pain of working with OS X client systems. Even better, both of the authors are very involved in the Mac community—Greg Neagle is part of the MacEnterprise steering committee, and Ed is the Executive Editor and an author for MacTech magazine and a member of the Apple Consultants Network.

Book Description

Tcl (Tool Command Language) is a very powerful and easy to learn dynamic programming language, suitable for a very wide range of uses. Tcl is regarded as one of the best-kept secrets in the software industry. This book gives you a hands-on experience on Tcl, helping you develop network-aware applications using this mature yet evolving language.

This book shows you how to create network-aware applications with Tcl language. Packed with practical examples, the book not only takes you through the implementation of network protocols in Tcl, but also key aspects of Tcl programming.

The book starts with the basic element of Tcl programming as we take a look at the syntax and fundamental commands of the language. To get us ready for network programming, we look at important Tcl features such as object-oriented programming, accessing files, packaging in TCL, event driven programming, and multithreaded applications. To create standalone single-file executable applications with Tcl we take a look at the Starpack technology, and ensure that we’ll be able to create robust applications with a thorough coverage of troubleshooting and debugging Tcl applications.

The book is really about network programming, and it will not let you down with its deep coverage of these topics. Of course we look at protocols, but there are plenty of practical examples to keep things moving along. We start with the TCP and UDP protocols, and look at some other protocols to see examples of synchronizing time with other servers, querying user information and authenticating users over LDAP and performing DNS queries.

Book Description

You know that servers have log files and performance measuring tools and that traditional network devices have LEDs that blink when a port does something. You may have tools that tell you how busy an interface is, but mostly a network device is a black box. Network Flow Analysis opens that black box, demonstrating how to use industry-standard software and your existing hardware to assess, analyze, and debug your network.

Unlike packet sniffers that require you to reproduce network problems in order to analyze them, flow analysis lets you turn back time as you analyze your network. You’ll learn how to use open source software to build a flow-based network awareness system and how to use network analysis and auditing to address problems and improve network reliability. You’ll also learn how to use a flow analysis system; collect flow records; view, filter, and report flows; present flow records graphically; and use flow records to proactively improve your network. Network Flow Analysis will show you how to:

• Identify network, server, router, and firewall problems before they become critical
• Find defective and misconfigured software
• Quickly find virus-spewing machines, even if they’re on a different continent
• Determine whether your problem stems from the network or a server
• Automatically graph the most useful data Download Now »
