In many ways, this is how I feel about Hadoop. Its inner workings are complex, resting as they do on a mixture of distributed systems theory, practical engineering, and com- mon sense. And to the uninitiated, Hadoop can appear alien. But it doesn’t need to be like this. Stripped to its core, the tools that Hadoop provides for building distributed systems—for data storage, data analysis, and coordination— are simple. If there’s a common theme, it is about raising the level of abstraction—to create building blocks for programmers who just happen to have lots of data to store, or lots of data to analyze, or lots of machines to coordinate, and who don’t have the time, the skill, or the inclination to become distributed systems experts to build the infrastructure to handle it. With such a simple and generally applicable feature set, it seemed obvious to me when I started using it that Hadoop deserved to be widely used. However, at the time (in early 2006), setting up, configuring, and writing programs to use Hadoop was an art. Things have certainly improved since then: there is more documentation, there are more examples, and there are thriving mailing lists to go to when you have questions. And yet the biggest hurdle for newcomers is understanding what this technology is capable of, where it excels, and how to use it. That is why I wrote this book.

Many people say they know what SQL injection is, but all they have heard about or experienced are trivial examples. SQL injection is one of the most devastating vulnerabilitie to impact a business, as it can lead to exposure of all of the sensitive information stored in an application’s database, including handy information such as usernames, passwords, names, addresses, phone numbers, and credit card details.

This completely updated classic (originally titled Practical UNIX Programming) demonstrates how to design complex software to get the most from the UNIX operating system. UNIX Systems Programming provides a clear and easy-to-understand introduction tothe essentials of UNIX programming. Starting with short code snippetsthat illustrate how to use system calls, Robbins and Robbins movequickly to hands-on projects that help readers expand their skill levels. This practical guide thoroughly explores communication, concurrency,and multithreading. Known for its comprehensive and lucid explanations of complicated topics such as signals and concurrency, the book features practical examples, exercises, reusable code, and simplified libraries for use in network communication applications. A self-contained reference that relies on the latest UNIX standards,UNIX Systems Programming provides thorough coverage of files, signals,semaphores, POSIX threads, and client-server communication. Thisedition features all-new chapters on the Web, UDP, and server performance. The sample material has been tested extensively in theclassroom.

The Linux kernel is one of the most interesting yet least understood open-source projects. It is also a basis for developing new kernel code. That is why Sams is excited to bring you the latest Linux kernel development information from a Novell insider in the second edition of Linux Kernel Development. This authoritative, practical guide will help you better understand the Linux kernel through updated coverage of all the major subsystems, new features associated with Linux 2.6 kernel and insider information on not-yet-released developments. You'll be able to take an in-depth look at Linux kernel from both a theoretical and an applied perspective as you cover a wide range of topics, including algorithms, system call interface, paging strategies and kernel synchronization. Get the top information right from the source in Linux Kernel Development.

Introduction On november 2, 1988 a new form of threat appeared with the Morris Worm, also known as the Internet Worm. This famous event caused heavy damages on the internet, by using two common unix programs, sendmail and fingerd. This was possible by exploiting a bu?er overflow in fingerd. This is probably one of the most outstanding attacks based on bu?er overflows. This kind of vulnerability has been found on largely spread and used daemons such as bind, wu-ftpd, or various telnetd implementations, as well as on applications such as Oracle or MS Outlook Express... The variety of vulnerable programs and possible ways to exploit them make clear that bu?er overflows represent a real threat. Generally, they allow an attacker to get a shell on a remote machine, or to obtain superuser rights. Bu?er overflows are commonly used in remote or local exploits. The first aim of this document is to present how bu?er overflows work and may compromise a system or a network security, and to focus on some existing protection solutions. Finally, we will try to point out the most interesting sets to secure an environment, and compare them on criteria such as e?ciency or performance loss. We are both third year computer science students at ENSEIRB (French national school of engineering), specialized in Networks and Distributed Systems. This study has been performed during our Network Administration project.
