Last update: February 23, 2004 Web Security Glossary The Web Security Glossary is an alphabetical index of terms and terminology relating to web application security. The purpose of the Glossary is to clarify the language used within the community. Abuse of Functionality: An attack technique that uses the features and functionality of a web site to coume, defraud, or circumvent the site's access controls. See also “Denial of Service”. ActiveX controls: ActiveX controls are software based on the Component Object Model (COM) and formerly known as OLE controls. ActiveX controls are portable, reusable, and can be utilized by many development languages. They are widely used by web- based applicatio to extend their functionality (ie: Windows Update site, etc.) See also “Java”, “Java Applets”, “JavaScript”, “Web Browser”. Application Server: A software server, normally using HTTP, which has the ability to execute dynamic web applicatio. Also known a middleware, this piece of software is normally italled
DownloadMetcalfe's Law, Web 2.0, and the Semantic WebIn talking about the Web, whether the original model, the so-called "Web 2.0", or the emerging Semantic Web (aka Web 3.0), one of the most important things to keep in mind is the network effect. The power of the Web emerges through the link space realized between Web pages. This is evidenced in a number of pieces of work, most famously the PageRank algorithm (Brin and Page, 1998) that was behind the early success of Google. Unlike traditional information retrieval algorithms, which were solely based on the information content of the individual pages, PageRank takes into effect how Web pages are linked to each other. By coupling this information with traditional indexing schemes, the system was able to outperform its competitors.
The network effect describes the value of a service to a user that arises from the number of people using the service. At its core, it captures that value increases as the number of users increases, because the potential links increase for every user as a new person joins. This is best quantified by what has come to be known as Metcalfe's Law. This proposition developed by Bob Metcalfe in the early 1980s, was originally defined to better explain to his customers why they needed more Ethernet boards than they were buying. Metcalfe hypothesized that while the cost of the network grew linearly with the number of connections, the value was proportional to the square of the number of users. For example, given n users of ethernet cards, the numberFriend or Foe? Web 2.0 in Technical CommunicationThe rise of Web 2.0 technology provides a platform for user-generated content.Publishing is no longer restricted to a few technical writers—any user can now contribute information. But the information coming from users tends to be highly specific, whereas technical documentation is comprehensive but less specific. The two types of information can coexist and improve the overall user experience. User-generated content also offers an opportunity for technical writers to participate as “curators”—by evaluating and organizing the information provided by end users.
Technical writers are accustomed to being the gatekeepers for product information. They carefully organize product documentation, online help, and other user assistance for their readers. Compare this to the chaos of the Web, where content is splattered across blogs, forums, wikis, and the like with little or no organizational scheme.
And yet, readers are turning to the chaos of the Web for information rather than reading the online help. They begin with a Google search and work through the results until they find something relevant.
User-generated content and technical documentation can be complementary rather than competitive. In this white paper, we explore the implications of user-generated content and discuss how technical writers can integrate this content into their overall strategy.

DownloadDefeating Compiler-level Buffer Overflow ProtectionBUFFER OVERFLOW ATTACK SARE THE most popular method intruders use to gain remote and privileged access to computer systems. Programs that fail to use appropriate bounds checking can allow an attacker to write data beyond the intended boundaries of a buffer and thus possibly corrupt control structures in the program. This enables an attacker to execute arbitrary code with the same privilege as the victim process. An attacker’s preference is usually to overwrite the saved instruction pointer that is pushed onto the stack before a function call or to overwrite a function pointer that will be used later in the program. It is also possible to use these attacks simply to overwrite other data.
This kind of attack is harder to prevent but, fortunately, is less common than the previous type and is not discussed here. Buffer overflows first gained attention with the release of the famed Morris worm which exploited a buffer overflow in fingerd [1]. Despite the attack used in the Morris worm, buffer overflows did not become popular until the release of two papers that detailed the discovery and exploitation of these vulnerabilities [2,3]. This paper discusses vulnerabilities in two compiler-level protection mechanisms, StackGuard and Point-Guard. While this paper takes a critical look at both of these solutions, it does not intend to make them seem insignificant. The attacks described in this paper help to show how StackGuard and PointGuard should be complemented to construct a more complete protection system.

LIKES Wide door openings Folding third row seat headrests High standard of finish To see how the people mover class has changed and progressed, one needs to go back to the eighties. At the time most people movers were based upon commercial variants in a manufacturers range and the vehicle from a distance looked more like a delivery van with windows. Move forward to the present time and look at the new Honda Odyssey. A purpose built vehicle that since its initial release in 1996 has been constantly improved and refined.
DISLIKES Centre sash only seat belt for second row seats Slightly awkward to use auto shifter Low height of rear hatch
COMFORT The front seats are soft and comfortable although support falls away somewhat under hard cornering especially in the shoulder area. Both front seats have foldable armrests that are nicely padded and comfortable to use. The second rows are similarly comfortable with adequate legroom. The third row has a more upright seating position, not ideal for longer trips but still comfortable enough for adults.
ERGONOMICS The driving position is closer to a normal passenger car or wagon in that it is lower than the previous high perched positions of the older generation people movers. Smaller drivers will notice the front of the Odyssey drops away quite sharply making parking slightly more difficult. The instrument binnacle has some of the most modern in design gauges going around, lit in Honda’s blue hues.

Using ComponentOne PropertyGrid™ for Silverlight, users can browse and edit properties on any .NET object. The C1PropertyGrid control is part of the C1.Silverlight.Extended assembly.
Introduction to the C1PropertyGrid Control
Like the original PropertyGrid control, the C1PropertyGrid control works based on a SelectedObject property.
Once this property is set, the control displays the object's public properties and allows the user to edit them.
For example, assuming you have a simple Customer class defined as follows:
public class Customer
{
public string Name { get; set; }
public string EMail { get; set; }
public string Address { get; set; }
public DateTime CustomerSince { get; set; }
public bool SendNewsletter { get; set; }
public int? PointBalance { get; set; }
}
You could build a user interface to display and edit customers using the following code:
public Page()
{
InitializeComponent();
// Create object to browse
var customer = new Customer();
// Create C1PropertyGrid
var pg = new C1PropertyGrid();
LayoutRoot.Children.Add(pg);
// Show customer properties
pg.SelectedObject = customer;
}

And the resulting application would look like this:
This simple UI allows users to edit all the properties in our Customer objects. It was built automatically based on the object’s properties and will be automatically updated if you add or modify the properties in the Customer class. Note that the C1PropertyGrid only displays properties of value type and strings. It does not display properties that contain objects with other properties.
Notice that properties are shown in alphabetical order by default. You can changeBreaking into computer networks from the Internet PDFWhat is this document about anyway? While I was writing this document a book “Hack Proofing Your Network” was released. I haven’t been able to read it (dunno if its in print yet, and besides - everything takes a while to get to South Africa). I did however read the first chapter, as it is available to the public. In this chapter the author writes about different views on IT security - hackers, crackers, script kiddies and everything in between. I had some thoughts about this and decided that it was a good starting point for this document. I want to simplify the issue - let us forget motives at the moment, and simply look at the different characters in this play. To do this we will look at a real world analogy. Let us assume the ultimate goal is breaking into a safe (the safe is a database, a password file, confidential records or whatever).
The safe is located inside of a physical building (the computer that hosts the data). The building is located inside of a town (the computer is connected to a network). There is a path/highway leading to the town and the path connects the town to other towns and/or cities. (read Internet/Intranet). The town/city is protected by a tollgate or an inspection point (the network is protected by a firewall, screening router etc.) There might be certain residents (the police) in the town looking for suspicious activity, and reporting it to the town’s mayor (the policeGLG Programming Tutorial for Java GLG Toolkit Version 2.9The GLG Toolkit provides a 100% pure Java class library that allows the user to load, display and animate GLG drawings in a Java application. A GLG drawing can be created in the GLG Graphics Builder or programmatically. It may contain predefined GLG components from the GLG Widgets catalog, such as graphs, gauges, meters, or custom graphics created by the user. A GLG Java application can be written as a stand-alone Java program or as an applet. To display GLG graphics, an application creates a GLG bean that can be used either as a top level applet or as a Java bean inside another Java component.
Examples of using the GLG bean in both cases appear later in this tutorial, as well as in the examples directory /examples_java. The GLG Toolkit for Java supports Java1 (AWT-based components), Java2 (Swing-based components) and Java2D.
