Adobe Flash Flash manipulates vector and raster graphics to provide animation of text, drawings, and still images. It allows bidirectional streaming of audio and video, and it can capture user input via mouse, keyboard, microphone and camera. Flash applications and animations can be programmed using the object-oriented language called ActionScript. Adobe Flash Professional is the most popular and user-friendly authoring tool for creating the Flash content, which also allows automation via the JavaScript Flash language (JSFL). History[edit] Open Screen Project[edit] As of February 2009[update], the specifications removing the restrictions on the use of SWF and FLV/F4V specs have been published.[6] The Flash Cast protocol—now known as the Mobile Content Delivery Protocol—and AMF protocols have also been made available,[6] with AMF available as an open source implementation, BlazeDS. As of 2012[update], the Open Screen Project is no longer accepting new applications according to partner BSQuare.
Prevent SQL Injection Attacks | Stop Attacks on SQL Vulnerabilties What makes the threat of SQL injection attacks so dangerous is the ease in which they can be launched and how many web sites are vulnerable to them. Attackers often use large botnets to systematically seek out vulnerable web sites to attack with little work being done on their part. Pair this with the fact that the number of sites vulnerable to this type of attack grows each year and it is clear to see why it remains at the top of the most critical vulnerabilities. Risks Associated with SQL Injection Even with the ease that an automated SQL injection attack can be carried out, if the attackers stood to gain nothing this threat would soon disappear. Not preventing SQL Injection attacks leaves your business at great risk of: Changes to or deletion of highly sensitive business information.Steal customer information such as social security numbers, addresses, and credit card numbers.Financial lossesBrand damageTheft of intellectual propertyLegal liability and fines Identifying the database
Server-side scripting Dynamic web page: example of server-side scripting (PHP and MySQL). Server-side scripting is a technique used in web development which involves employing scripts on a web server which produce a response customized for each user's (client's) request to the website. The alternative is for the web server itself to deliver a static web page. Server-side scripting is often used to provide a customized interface for the user. Programs that run on a user's local computer without ever sending or receiving data over a network are not considered clients, and so the operations of such programs would not be considered client-side operations. History[edit] Netscape introduced an implementation of JavaScript for server-side scripting with Netscape Enterprise Server, first released in December, 1994 (soon after releasing JavaScript for browsers).[1][2] Server-side scripting was later used in early 1995 by Fred DuFresne while developing the first web site for Boston, MA television station WCVB.
SQL Injection Attacks and Some Tips on How to Prevent Them Introduction Security in software applications is an ever more important topic. In this article, I discuss various aspects of SQL Injection attacks, what to look for in your code, and how to secure it against SQL Injection attacks. Although the technologies used here are SQL Server 2000 and the .NET Framework, the general ideas presented apply to any modern data driven application framework, which makes attacks potentially possible on any type of application that depends on that framework. What is a SQL Injection Attack? A SQL Injection attack is a form of attack that comes from user input that has not been checked to see that it is valid. There are two main types of attacks. An example of what an attacker might do In the following example, assume that a web site is being used to mount an attack on the database. SELECT ProductName, QuantityPerUnit, UnitPrice FROM Products WHERE ProductName LIKE 'G%' This is all fine if the data is valid, but what if the user types something unexpected?
Client-side scripting By viewing the file that contains the script, users may be able to see its source code. Many web authors learn how to write client-side scripts partly by examining the source code for other authors' scripts. Due to security restrictions, client-side scripts may not be allowed to access the user's computer beyond the web browser application. Techniques like ActiveX controls can be used to sidestep this restriction. Client-side scripting is not inherently unsafe. List of Client-Side Scripting Languages[edit] References[edit] See also[edit] Server-side scripting StopTheHacker | Experts Explain: SQL Injection Website security is an arms race. Malicious hackers modify their methods constantly to infect benign and legitimate websites with web-malware. One of the most common techniques used to compromise millions of websites is called SQL Injection. SQL injection attacks have been making headlines increasingly in the past few months. What is SQL? SQL is well described in its Wikipedia entry . Why do we need SQL? SQL also allows for questions (also called queries) asked of a database to be optimized in a manner that speeds up their processing and provides the answer faster. Why does my website use SQL? Visitors can now not only read information on the webpages, but can also interact with the website by storing information about themselves. What is a code injection attack? What vulnerabilities lead to SQL Injection attacks? An example of SQL Injection Consider the relatively recent spate of attacks on millions of websites that led to the injection of the following code:
Ajax (programming) Ajax is not a single technology, but a group of technologies. HTML and CSS can be used in combination to mark up and style information. The DOM is accessed with JavaScript to dynamically display, and allow the user to interact with, the information presented. JavaScript and the XMLHttpRequest object provide a method for exchanging data asynchronously between browser and server to avoid full page reloads. In 1996, the iframe tag was introduced by Internet Explorer to load or to fetch content asynchronously. In 1998, Microsoft Outlook Web App team implemented the first component XMLHTTP by client script. Google made a wide deployment of standards-compliant, cross browser Ajax with Gmail (2004) and Google Maps (2005).[6] The term "Ajax" was publicly stated on 18 February 2005 by Jesse James Garrett in an article titled "Ajax: A New Approach to Web Applications", based on techniques used on Google pages.[1] get-ajax-data.js: send-ajax-data.php: jQuery example
What is SQL Injection and How to Fix It SQL Injection is one of the many web attack mechanisms used by hackers to steal data from organizations. It is perhaps one of the most common application layer attack techniques used today. It is the type of attack that takes advantage of improper coding of your web applications that allows hacker to inject SQL commands into say a login form to allow them to gain access to the data held within your database. In essence, SQL Injection arises because the fields available for user input allow SQL statements to pass through and query the database directly. SQL Injection: An In-depth Explanation Web applications allow legitimate website visitors to submit and retrieve data to/from a database over the Internet using their preferred web browser. SQL Injection is the hacking technique which attempts to pass SQL commands (statements) through a web application for execution by the backend database.

Dynamic web page Dynamic web page: example of server-side scripting (PHP and MySQL). A client-side dynamic web page processes the web page using HTML scripting running in the browser as it loads. JavaScript and other scripting languages determine the way the HTML in the received page is parsed into the Document Object Model, or DOM, that represents the loaded web page. The same client-side techniques can then dynamically update or change the DOM in the same way. DHTML is the umbrella term for technologies and methods used to create web pages that are not static web pages. Client-side-scripting, server-side scripting, or a combination these make for the dynamic web experience in a browser. Basic concepts[edit] Classical hypertext navigation, with HTML or XHTML alone, provides "static" content, meaning that the user requests a web page and simply views the page and the information on that page. However, a web page can also provide a "live", "dynamic", or "interactive" user experience. History[edit] Example
Understanding SQL Injection Structured Query Language (SQL) is used to query, operate, and administer database systems such as Microsoft SQL Server, Oracle, or MySQL. The general use of SQL is consistent across all database systems that support it; however, there are intricacies that are particular to each system. Database systems are commonly used to provide backend functionality to many types of web applications. This white paper will describe SQL injection attacks, how they are performed, and precautions that should be taken inside applications or networks to reduce risks that are associated with SQL injection attacks. A SQL injection attack involves the alteration of SQL statements that are used within a web application through the use of attacker-supplied data. Ramifications of Successful SQL Injection Attacks Authentication Bypass: This attack allows an attacker to log on to an application, potentially with administrative privileges, without supplying a valid username and password. Defenses in the Application
FileZilla - The free FTP solution 10 Ways to Prevent or Mitigate SQL Injection Attacks "Failure to Preserve SQL Query Structure (aka 'SQL Injection')" appears at number 2 in the CWE/SANS TOP 25 Most Dangerous Programming Errors list published on February 16. And for good reason: SQL injection attacks pose a massive potential threat to your organization. That's because, if successful, they could allow hackers to compromise your network, access and destroy your data, and take control of your machines. What Is SQL Injection? The principal behind SQL injection is pretty simple. For example, imagine this line of code: SELECT * FROM Users WHERE Username='$username' AND Password='$password' which is designed to show all records from the table "Users" for a username and password supplied by a user. 1' or '1' = '1 resulting in the query: SELECT * FROM Users WHERE Username='1' OR '1' = '1' AND Password='1' OR '1' = '1' The hacker has effectively injected a whole OR condition into the authentication process.
