Web Security : Attacking AJAX - Subverting AJAX with Injected XML, Subverting AJAX with Injected JSON
Your application uses AJAX and it passes data back in XML format. To test the client-side’s handling of bad XML data, you’ll need to generate bad XML and have it parsed by your application.
.NET Security : Programming the Event Log Service (part 3) - Using Custom Event Logs, Monitoring Event Logs
You can create custom event logs by specifying the name you wish to use with the Log property of the EventLog class. When you write the first event to the log with the WriteEntry method, the ELS will create the custom log automatically.
.NET Security : Programming the Event Log Service (part 2) - Reading Event Logs, Writing Events
The first step towards reading the contents of an event log is to create a new instance of the EventLog class, specifying the name of the log we want to read from as a constructor argument.
.NET Security : Programming the Event Log Service (part 1) - Querying the Event Log System, Using Event Sources
In this section, we discuss the overall structure of the ELS and introduce three important elements of its design: event logs, event sources, and events. The principal security aspect of the ELS is as the means to audit Windows security events, for which .NET unfortunately does not provide good support.

Cyanogen-Mod is the most popular custom ROM for Android. It’s available for pretty much every device and is the perfect starting point for anyone wanting to flash a ROM to their phone for the first time due to its stability, reliability and ease of use.
Hack Your Phone (Part 3)
When you flash a custom ROM on an Android phone the entire device gets wiped and replaced with the new version you are flashing. When you reboot for the first time it may take a while for the phone to start up, so don’t be alarmed and just leave the phone to do what it needs to.
Hack Your Phone (Part 2)
The other issue that you should be aware of is that a rooted phone will no longer receive over-the-air updates from the manufacturer. Since custom ROMs based on the updated version will be available almost instantly, however, this won't inconvenience you.
Hack Your Phone (Part 1) - Launcher or ROM
Flashing a ROM is a pretty straightforward process, although once you’ve been using your device for a while the whole backup and restore procedure for your data can be a pain. If you only want to freshen up the look and feel of your phone then installing a new launcher represents a good compromise.
Windows 7 : Blocking Hackers with Windows Firewall (part 3) - Advanced Firewall Configuration
If you're not a professional administrator, it's best to stay out of this area altogether. You certainly don't want to guess and hack your way through things just to see what happens. Doing so could lead to a real can of worms that makes it impossible or extremely difficult to access the Internet.
Windows 7 : Blocking Hackers with Windows Firewall (part 2) - Making Exceptions to Firewall Protection
When Windows Firewall is turned on and running, you don't really have to do anything special to use it. It will be on constant vigil, automatically protecting your computer from hackers and worms trying to sneak in through unprotected ports.

COM+ security can be configured programmatically, or administratively . When applying .NET attributes to configure RBS and PAS, you must bear in mind that the system administrator can change the security configuration for your components or even disable security completely.
Programming COM+ Security (part 1) - Creating the Serviced Component, Specifying the COM+ Application Type
A serviced component must inherit from the System.EnterpriseServices.ServicedComponent class and must be a member of a strong-named assembly. The following statements list the SecurityProTracker class, which extends ServicedComponent and implements the IDefectTracker interface.
COM+ Security : COM+ Security Explained
When the current RID master has failed, you need to seize the role and move it to another domain controller. It is important that, after the role has been seized, the original role holder is not brought back online.
Password Hacks (Part 3) - Alternatives to passwords
A Pass-Window system is also effective. It places a unique key pattern on a transparent section of an identity card. This has to be held over a generated pattern image on a display and, when it is, a series of digits is shown that can then be entered as your single-use password.
Password Hacks (Part 2) - Criminal activity
The hacking group Anonymous, for example, has been involved in a number of denial-of-service attacks on high profile companies including Master-card and Visa, which was in response to both firms withdrawing support for Wiki-leaks, which had begun publishing 250,000 leaked diplomatic cables.
