ModSecurity 2.5. Prevent web application hacking with this easy to use guide

Magnus Mischel, Brian Rectanus

With more than 67% of web servers running Apache and web-based attacks becoming more and more prevalent, web security has become a critical area for web site managers. Most existing tools work on the TCP/IP level, failing to use the specifics of the HTTP protocol in their operation. Mod_security is a module running on Apache, which will help you overcome the security threats prevalent in the online world.A complete guide to using ModSecurity, this book will show you how to secure your web application and server, and does so by using real-world examples of attacks currently in use. It will help you learn about SQL injection, cross-site scripting attacks, cross-site request forgeries, null byte attacks, and many more so that you know how attackers operate.Using clear, step-by-step instructions this book starts by teaching you how to install and set up ModSecurity, before diving into the rule language with examples. It assumes no prior knowledge of ModSecurity, so as long as you are familiar with basic Linux administration, you can start to learn right away.Real-life case studies are used to illustrate the dangers on the Web today ñ you will for example learn how the recent worm that hit Twitter works, and how you could have used ModSecurity to stop it in its tracks. The mechanisms behind these and other attacks are described in detail, and you will learn everything you need to know to make sure your server and web application remain unscathed on the increasingly dangerous web. Have you ever wondered how attackers figure out the exact web server version running on a system? They use a technique called HTTP fingerprinting, and you will learn about this in depth and how to defend against it by flying your web server under a false flag.The last part of the book shows you how to really lock down a web application by implementing a positive security model that only allows through requests that conform to a specific, pre-approved model, and denying anything that is even the slightest bit out of line.

Moodle 1.9 for Design and Technology. Support and Enhance Food Technology, Product Design, Resistant Materials, Construction, and the Built Environment using Moodle VLE

Paul Taylor, Moodle Trust

Educators use the Moodle web application to create effective online learning sites. Creating such learning environments that suit Design and Technology subjects requires understanding and implementation of both basic and advanced Moodle features.This book takes a detailed look at Moodle features with examples of how to fully support the Design and Technology curricula using Moodle. It will guide you to incorporate specific modules and blocks to enhance learning as well as allow detailed tracking of performance by using formative and summative assessment tools with ease.We start with setting up a very basic Moodle course for Design and Technology, and then set up some basic resources and some interactive material. You will customize your own courses and create a course for each of the key areas of the DT subjects and add material to them. We will create some basic reporting and assessment tools and enhance the look of the course. We will use Moodle's detailed and sophisticated gradebook to assess your student s ' learning progress in activities from an assignment to an offline activity. Then we will support students in designing a product or trying a new recipe in food technology in market research to find out exactly what the public wants in relation to their product, by designing a questionnaire. We will allow product design or resistant material students use the HTML features of the questionnaire module to incorporate images into the questions to make it clearer to respondents what it is they are trying to make and sell.We will allow students in construction to gather and organize their research material in a great deal of detail and also allow them to better understand their target market and the materials used in their construction through detailed questioning. We will allow food technology students to discuss and receive constructive feedback on food products that contribute to health issues that will enable them to make informed decisions and therefore better quality products. Then we explore several components within Moodle's core functionality and some third-party sources to display the progress of the student's work and development. We then have an overview of the different design portfolios available. Finally we look at additional ways to enhance the teaching and learning of D ' T with Moodle using third-party modules and add-ons.
