Computer forensics involves using various means to analyze, report, and recover information from computers or digital storage media, generally for legal purposes. The outcome in general is to provide the information gathered in such a way that it is useful for the person requesting the information. This includes the recovery of passwords, analyzing computer break-ins or attempts, recovering data from a hard drive after it's been "erased", and so on. In the article by Willie Pritchett and David De Smet authors of BackTrack 5 Cookbook we will examine how BackTrack can be utilized for forensic purposes.
In this article, we will cover:
Intrusion detection and log analysis
Recursive directory encryption/decryption
Scanning for signs of rootkits
Recovering data from a problematic source
Retrieving a Windows password
Resetting a Windows password
Looking at the Windows registry entries
In this article by Vivek Ramachandran, author of BackTrack 5 Wireless Penetration Testing Beginner’s Guide, we will focus on attacking the client. Most people exclude the client from their list when they think about WLAN security. This article will prove beyond doubt why the client is just as important as the access point when penetrating testing a WLAN network. The client can be either a connected or isolated un-associated client. We will look at various attacks, which can be used to target the client.
We will cover the following:
- Honeypot and Mis-Association attacks
- Caffe Latte attack
- De-Authenticaton and Dis-Association attacks
- Hirte attack
- AP-less WPA-Personal cracking
Wireless Networks have become ubiquitous in today's world. Millions of people use them worldwide every day at their homes, offices, and public hotspots to log on to the Internet and do both personal and professional work.
In this article by Vivek Ramachandran, author of BackTrack 5 Wireless Penetration Testing Beginner’s Guide, we will look at how we can conduct advanced attacks. We will primarily focus on Man-in-the-Middle (MITM) attack, which requires a certain amount of skill and practice to conduct successfully. Once we have done this, we will use this MITM attack as a base to conduct more sophisticated attacks such as Eavesdropping and Session Hijacking.
We will cover the following:
- Man-in-the-Middle attack
- Wireless Eavesdropping using MITM
- Session Hijacking using MITM

All web applications and web servers have security vulnerabilities and there is every chance that our website will be compromised. Most web hosts have their own backup procedures in place, but it is not uncommon for a web host to become victim to an attack, and have problems with a small percentage of its customer backups. Because of this it is very important that we keep backups of our website. In this article by Michael Peacock, we will see how to backup our website and restore it back gain from our backup.Read Backing Up and Restoring TYPO3 Websites in full

This article covers some advanced topics such as conditions, raised events, and so on.
In this article by Ezra Schwartz, author of Axure RP 6 Prototyping Essentials, we will cover a set of features such as raised events, conditional logic and variables, introduction to a terminology which is usually associated with programming and suggests complexity. It is understandable if you are not interested in, or are intimidated by, the prospect of coding, and wish to avoid using this set of Axure features as long as possible. You should not.
First, rest assured that no coding is involved. By now, you are familiar with Axure's Interactions and the Case Editor features, which require you only to select from a contextual selection of options and construct interactions by pointing and clicking. The only typing required is the labeling. You will find a similar easy-to-use interface when you use features such as the Condition Builder or simulate "drag and drop".
Secondly, think about some of the terminologies and methods we use in interaction design. We use branching logic to determine use cases, scenarios, and how functionality responds to user interaction under certain conditions. Axure makes it fairly easy to model the logic we need, in order to visualize branching paths, and express it in the interactive prototype.Read Axure RP 6 Prototyping Essentials: Advanced Interactions in full
Three dimensions are better than two — and it's not a secret anymore that 3D is here to stay. Gone are the days when Flash was just used for 2D animations. In the last few years, online Flash content has undergone a revolution with the introduction of real-time 3D engines for Flash. Away3D is the big daddy of them all—which makes it the ultimate resource for top-rated 3D content development and for powering today's coolest games and Flash sites.
In this article by Michael Ivanov, author of Away3D 3.6 Cookbook, we will see how to detect collisions between objects in Away3D.Read Away3D: Detecting Collisions in full
Away3D includes a large selection of materials. There are various shading techniques that can be used by these materials, which allows for a selection of materials ranging from those that display a simple texture map to those more advanced materials, which produce more interesting detailed results like reflections, lighting, and shadowing.
In this article by Matthew Casperson, author of Away3D 3.6 Essentials, we will cover Pixel Bender, and seen how it has been used by Away3D to create some of these advanced materials. Those materials that can be lit from an external light source are listed, along with a table that breaks down the types of light sources that affect these materials. We will also see how resources, like textures, can be embedded into the final SWF, or loaded from external resources.Read Away3D 3.6: Applying Light and Pixel Bender materials in full
