Cisco Unity Connection (Networking Technology: IP Communications) ReviewSchulz's book can be considered as two parts. The first part, covered in the chapters 1 and 2, is the overview and planning. Its strongest recommendation seems to be to design in as much detail as possible your computing network for voicemail. Especially take into account scalability. Future expansion should be considered from the start. The CUC core product can handle up to 20 000 users on a single server, which is certainly impressive. But if even this is insufficient, you have the choices of using more servers or perhaps digital networking and VPIM [Voice Profile for Internet Mail] to extend the limit on one server.
VPIM is also important, for it lets a CUC network with another vendor's voicemail system, if the latter also supports VPIM. A pragmatic concern if your company already has that other vendor's system deployed as a legacy centre.
One important aspect is the geographic distribution of users. The book uses an example of a company with its employees mostly on both US coasts. For high availability, this suggests deploying a server on each coast. Then CUC lets you build an intersite network so that you can easily administer just one unified voicemail centre.
The second part of the book is the majority of the text. It delves into the many details of system administration of CUC. Accompanied by numerous screenshots of windows of supported options. One of which I describe here, as especially pertinent to voicemail. It has to do with message aging. Voicemail is stored as WAV files, and it is inherent that a typical voicemail is larger than your standard email, even if the latter is in HTML, as many are these days. So voicemail takes up more room than email. To handle this, CUC offers a message aging policy. Users can move a voicemail into a Deleted Items folder. But the voicemail still exists in the system, taking up space. You can adjust a number of days parameter, so if a voicemail is in the folder after that limit, it is permanently deleted.Cisco Unity Connection (Networking Technology: IP Communications) OverviewCisco Unity ConnectionThe comprehensive guide to Cisco Unity Connection voice messaging system design, implementation, and troubleshootingDavid SchulzCisco Unity Connection presents all the concepts and techniques you need to successfully plan, design, implement, and maintain Cisco Unity Connection voice messaging systems.

Managing Security with Snort and IDS Tools ReviewThis is basically a book about intrusion detection using all open source tools. It starts with an introductory chapter that explains the problem of defining an intrusion and why it is becoming more and more of a problem. It follows up with a chapter on network traffic analysis including packet sniffing and using tcpdump and ethereal. Then comes the meat of the text - installing Snort. Of course to really understand how to use Snort you have to understand how attacks occur and the common methods used. The authors provide a really nice chapter on this subject. After that come five chapters on configuring, deploying, and managing Snort rules, intrusion prevention strategies, and tuning. Once Snort is up and running the authors examine the use of ACID and SnortCenter as Snort IDS management consoles. Either of these products drastically decreases the burden of analyzing what has happened and is happening on the intrusion detection forefront. The book ends with additional tools for Snort IDS management and implementation strategies for high-bandwidth situations.
There are other very good books on Snort but one of the things that makes this one particularly valuable is that it also looks at other open source tools and provides a good basic background on intrusion detection theory. Managing Security with Snort and IDS Tools is highly recommended for those in charge of intrusion detection and prevention in a network environment and planning to implement a system their self.Managing Security with Snort and IDS Tools Overview
Intrusion detection is not for the faint at heart. But, if you are a network administrator chances are you're under increasing pressure to ensure that mission-critical systems are safe--in fact impenetrable--from malicious code, buffer overflows, stealth port scans, SMB probes, OS fingerprinting attempts, CGI attacks, and other network intruders.

Designing a reliable way to detect intruders before they get in is a vital but daunting challenge. Because of this, a plethora of complex, sophisticated, and pricy software solutions are now available. In terms of raw power and features, SNORT, the most commonly used Open Source Intrusion Detection System, (IDS) has begun to eclipse many expensive proprietary IDSes. In terms of documentation or ease of use, however, SNORT can seem overwhelming. Which output plugin to use?How do you to email alerts to yourself? Most importantly, how do you sort through the immense amount of information Snort makes available to you?

Many intrusion detection books are long on theory but short on specifics and practical examples. Not Managing Security with Snort and IDS Tools.This new book is a thorough, exceptionally practical guide to managing network security using Snort 2.1 (the latest release) and dozens of other high-quality open source other open source intrusion detection programs.

Managing Security with Snort and IDS Tools covers reliable methods for detecting network intruders, from using simple packet sniffers to more sophisticated IDS (Intrusion Detection Systems) applications and the GUI interfaces for managing them. A comprehensive but concise guide for monitoring illegal entry attempts, this invaluable new book explains how to shut down and secure workstations, servers, firewalls, routers, sensors and other network devices.

Step-by-step instructions are provided to quickly get up and running with Snort. Each chapter includes links for the programs discussed, and additional links at the end of the book give administrators access to numerous web sites for additional information and instructional material that will satisfy even the most serious security enthusiasts.

Managing Security with Snort and IDS Tools maps out a proactive--and effective--approach to keeping your systems safe from attack.
