1. NO -  may not function well
2. Low - requires human assistance in replicating and moving from computer to computer
3.  Medium - slow infection speed and little damage
4.  High - great infection speed and do considerable damage.

Hack websites and damage to a web application.

Works with Firefox: 2.0.0.8 – 3.6a1pre

Cross-Site Scripting (XSS) is a common flaw found in todays web applications. XSS flaws can cause serious damage to a web application. Detecting XSS vulnerabilities early in the development process will help protect a web application from unnecessary flaws. XSS-Me is the Exploit-Me tool used to test for reflected XSS vulnerabilities.

XSS-Me is the Exploit-Me tool used to test for reflected Cross-Site Scripting (XSS). It does NOT currently test for stored XSS.rnrnThe tool works by submitting your HTML forms and substituting the form value with strings that are representative of an XSS attack.rnrnIf the resulting HTML page sets a specific JavaScript value (document.vulnerable=true) then the tool marks the page as vulnerable to the given XSS string.rnrnThe tool does not attempting to compromise the security of the given system. It looks for possible entry points for an attack against the system. There is no port scanning, packet sniffing, password hacking or firewall attacks done by the tool.rnrnYou can think of the work done by the tool as the same as the QA testers for the site manually entering all of these strings into the form fields.

Tutorial 1:Getting started with C++.

Tutorial 1:Getting started with C++.

Hi! Friends,

Today  I have started a new program to post c++ tutorial. we will start from the root of c++.

Step -1 For starting writing our programs we need a text editor with compiler

I prefer to use turbo C++.

You can download Turbo C++ from Net.

We will Learn --

• How to make basic program
• How to compile a program
• Checking error in the program
• Increasing readability of a program
• Types of errors 
• What are header files
• What are keywords
• What are identifiers
• What are tokens
• For what  # is used
• What are variables
• What are datatypes
• Types of datatypes
• Fundamental and derived datatypes
• Array in C++
• Classes in C++
• Loops in C++
• Comments in C++
• Multiple and single line comments
• Use of clrscr( ) function
• What are functions
• What are escape sequences
• Use of semicolon

        

And many more!!

******************************************************

Some Basic Definitions

·       Keywords- words which have predefined meaning is called a keyword.

·       Variables: - variables are the name storage location whose value can be changed during execution.

·       Token: -Token are the smallest individual units.

---------------------------------------------------------------------------------

Making a very simple program in C++.

# include<iostream.h>     //header file

#include<conio.h>             //another header file   

{ clrscr( );                  //use to clear the screen

  cout<<”ashutosh”;  /*cout stands for standard output device(monitor)*/

  cout<<”/n your name here”;

}

--------------------------------------------------------------------------------

Output of this program-

ashutosh

your name here

-------------------------------------------------------------------------------

What we get from the above program.

·       In the program we have used # as a preprocessor

·       Iostream.h is the header file which we have used for input/output streams

·       Conio.h is another header file which we have to use for using the function clrscr( )

·       //(double slash are used for single line comments.

·       /* is used for multiple line comments.

·       Comments are not executed by the compiler.

·       /n is the escape sequence which is used for next line.

·       ;(semicolon) is used as a statement terminator.
