Simple Overview About XSS?

What is XSS?

XSS mean Cross Site Scripting

Cross-site scripting (XSS) is a type of computer security vulnerability typically found in web applications. XSS enables attackers to inject client-side scripts into web pages viewed by other users. A cross-site scripting vulnerability may be used by attackers to bypass access controls such as the same-origin policy.

Cross-site Scripting (XSS) refers to client-side code injection attack wherein an attacker can execute malicious scripts (also commonly referred to as a malicious payload) into a legitimate website or web application. XSS is amongst the most rampant of web application vulnerabilities and occurs when a web application makes use of unvalidated or unencoded user input within the output it generates.

By leveraging XSS, an attacker does not target a victim directly. Instead, an attacker would exploit a vulnerability within a website or web application that the victim would visit, essentially using the vulnerable website as a vehicle to deliver a malicious script to the victim’s browser.

Step-By-Step walkthrough of a simple XSS attack:

Following pseudo-code is used to display the most recent comment on a web page.

print "<html>"
print "<h1>Most recent comment</h1>"
print database.latestComment
print "</html>"

Simple Overview About WebMethods?

What is Web Methods?

webMethods Developer is the Java-based Integrated development environment (IDE) for developing code on the webMethods Integration Server.

It allows development in webMethods Flow which is a graphical programming language designed to simplify and speed up integration application development.[1] With version 7 of the webMethods product suite, webMethods Developer started to be replaced by webMethods Designer, an Eclipse-based IDE. This transition has not been finished yet and both products exist side by side.

Program Features

Writing graphical flow and java services (the programming logic)
Defining and modifying documents and mapping logic
Testing, debugging and executing services
Creation and configuration of web services[3]
Editing adapter service and notifications (used to connect with external systems)

Simple Introduction about Traceus.JS?

What is Traceur.Js?

Traceur is a compiler that takes ECMAScript Edition 6 (ES6) (including classes, generators, destructuring and much more) and compiles it down to regular Javascript (ECMAScript Edition 5 [ES5]) that runs in your browser.

Traceur is a compiler / transpiler which allows you to make use of all the future JavaScript features that are not currently a native offering in modern web browsers. In addition to making all features of ES6 available to you, Traceur also supports some ES.

You can try Traceur in several ways:

Typing or pasting ES6 code into the Read-eval-print-loop page.
Include Traceur in a Web page and compile ES6 script content on the fly (see below)
Use node to compile ES6 to ES5 offline and include the result in Web pages or just run the result in node.

NPM Command

npm install traceur

Simple Discussion About Ad Hoc Reporting?

What is Ad Hoc?

Ad hoc analysis is a business intelligence process designed to answer a single, specific business question. The product of ad hoc analysis is typically a statistical model, analytic report, or other type of data summary.

Ad hoc reporting refers to reports that are put together creatively by users in real-time, rather than pre-designed according to a template.

An ad hoc report is a report that is created on the fly, displaying information in a table or a chart that is the result of a question that has not already been codified in a production report. There is a limit to the number of such production reports and business questions that can be anticipated and coded in advance so that users can consult them whenever they want.

Moreover, as businesses are always changing, the questions people want to ask of their data are always changing, so any reporting system needs to accommodate the creation and running of ad hoc reports. Making that an easy process for the average business user is key because most ad hoc reporting tools are designed for database experts to use, often requiring knowledge of structured query language, or SQL.
