The Internet is connecting enterprises into a global economy. Companies are exposing their directories, or a part of their directories, to customers, business partners, the Internet as a whole, and to potential "hackers." If the directory structure is compromised, then the whole enterprise can be at risk. Security of this information is of utmost importance. This book provides examples and implementation guidelines on building secure and structured enterprise directories. The authors have worked with corporations around the world to help them design and manage enterprise directories that operate efficiently and guard against outside intrusion. These experts provide the reader with "best practices" on directory architecture, implementation, and enterprise security strategies.

A Primer for Computational Biology aims to provide life scientists and students the skills necessary for research in a data-rich world. The text covers accessing and using remote servers via the command-line, writing programs and pipelines for data analysis, and provides useful vocabulary for interdisciplinary work. The book is broken into three parts: Introduction to Unix/Linux: The command-line is the "natural environment" of scientific computing, and this part covers a wide range of topics, including logging in, working with files and directories, installing programs and writing scripts, and the powerful "pipe" operator for file and data manipulation. Programming in Python: Python is both a premier language for learning and a common choice in scientific software development. This part covers the basic concepts in programming (data types, if-statements and loops, functions) via examples of DNA-sequence analysis. This part also covers more complex subjects in software development such as objects and classes, modules, and APIs. Programming in R: The R language specializes in statistical data analysis, and is also quite useful for visualizing large datasets. This third part covers the basics of R as a programming language (data types, if-statements, functions, loops and when to use them) as well as techniques for large-scale, multi-test analyses. Other topics include S3 classes and data visualization with ggplot2.

Lightweight Directory Access Protocol (LDAP) is the standard for directory information access and is the underlying protocol for a variety of email systems, Web systems, and enterprise applications. LDAP enables central management of users, groups, devices, and other data, thereby simplifying directory management and reducing the total cost of ownership. Understanding and Deploying LDAP Directory Services, written by the creators of the protocol, is known as the LDAP bible and is the classic text for learning about LDAP and how to utilize it effectively. The Second Edition builds on this success by acting as an exhaustive resource for designing, deploying, and maintaining LDAP directory services. Topics such as implementation pitfalls, establishing and maintaining user access to information, troubleshooting, and real-world scenarios will be thoroughly explored.

One of the main concerns for digital photographers today is asset management: how to file, find, protect, and re-use their photos. The best solutions can be found in The DAM Book, our bestselling guide to managing digital images efficiently and effectively. Anyone who shoots, scans, or stores digital photographs is practicing digital asset management (DAM), but few people do it in a way that makes sense. In this second edition, photographer Peter Krogh -- the leading expert on DAM -- provides new tools and techniques to help professionals, amateurs, and students: Understand the image file lifecycle: from shooting to editing, output, and permanent storage Learn new ways to use metadata and key words to track photo files Create a digital archive and name files clearly Determine a strategy for backing up and validating image data Learn a catalog workflow strategy, using Adobe Bridge, Camera Raw, Adobe Lightroom, Microsoft Expression Media, and Photoshop CS4 together Migrate images from one file format to another, from one storage medium to another, and from film to digital Learn how to copyright images To identify and protect your images in the marketplace, having a solid asset management system is essential. The DAM Book offers the best approach.

A comprehensive guide to network directories with strategic advice for managing current resources and conquering network growing pains Roughly 80 percent of the money spent on managing electronic directories is due to needless duplication of work and information. For the average Fortune 500 company, which has anywhere from 180 to 1,000 different directories in its network, this duplication results in huge amounts of squandered revenue. The problem is that directory management is arguably the biggest and most confusing job faced by network managers. This book promises to take the headache out of the process, guiding you toward a streamlined, cost-efficient structure for migrating old directory systems and making the most of new ones in order to allow for rapid network growth. Whether your organization is large or small, this unprecedented guide demonstrates exactly how to sort out the current directory landscape and then effectively match and migrate each individual directory within a single, well-organized network. Beginning with a comprehensive overview of the range of possible directories, the authors discuss current and forthcoming directory applications and then offer detailed strategies for designing and maintaining the entire directory network. You'll also find the latest emerging trends in directory technology and gain a glimpse of things to come for directories in the future. * This practical, hands-on book: * Details the two major directory-related standards, X.500 and LDAP * Explains each component's role in a directory system * Provides an overview of network security * Discusses the role of directories and directory services in network management * Reviews each of the major network operating systems * Investigates the role of the directory in efforts to combine voice and electronic messaging * Covers the types of meta-directories and why to develop one Visit our Web site at www.wiley.com/compbooks/

This practical, hands-on guide shows how to develop a structured approach to biological data and the tools needed to analyze it. It's aimed at scientists and students learning computational approaches to biological data, as well as experienced biology researchers starting to use computers to handle data.

Directory services matter to nearly every organization because they help centrally manage information and thereby reduce the costs of computing services. LDAP (Lightweight Directory Access Protocol) is a set of protocols that have become the internet standard for accessing directories. Many people need to understand directory services and LDAP in order to make decisions for their business. The books currently available are too advanced for technical managers and those new to directory services. This book is designed to fill that need. The author spends the first half of the book exploring how directory services and LDAP work and then the second half discussing the most popular implementations - OpenLDAP, Microsoft Active Directory, and Directory Server - for those who are trying to compare products. This book provides the technical foundation that will enable IT managers to make sound business decisions and developers to move on to more advanced books.
