Framekiller
A framekiller (or framebuster or framebreaker) is a technique used by websites and web applications to prevent their web pages from being displayed within a frame. A frame is a subdivision of a Web browser window and can act like a smaller window. A framekiller is usually used to prevent a website from being loaded from within a frameset without permission or as an attack, as with clickjacking. Implementations Framekillers are implemented using JavaScript that validates if the current window is the main window. The recommended approach is to block rendering of the window by default and only unblock it after confirming the current window is the main one: html if (self top) else This approach was proposed in 2010 by Gustav Rydstedt, Elie Bursztein, Dan Boneh and Collin Jackson in a paper that highlighted the limitations of existing frame-busting techniques along with techniques allowing to bypass them. Alternative solutions An alternative choice is to allow the user to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elie Bursztein
Elie Bursztein, born 1 June 1980 in France, is a French computer scientist and software engineer. He currently leads Google’s Security and Anti-Abuse Research Team. Education and early career Bursztein obtained a computer engineering degree from EPITA in 2004, a master’s degree in computer science from Paris Diderot University/ENS in 2005, and a PhD in computer science from École normale supérieure Paris-Saclay in 2008 with a dissertation titled ''Anticipation games: Game theory applied to network security''. His PhD advisor was Jean Goubault-Larrecq. Before joining Google, Bursztein was a post-doctoral fellow at Stanford University's Security Laboratory, where he collaborated with Dan Boneh and John Mitchell on web security, game security, and applied cryptographic research. His work at Stanford University included the first cryptanalysis of the inner workings of Microsoft’s DPAPI (Data Protection Application Programming Interface), the first evaluation of the effect ...

Clickjacking
Clickjacking (classified as a user interface redress attack or UI redressing) is a malicious technique of tricking a user into clicking on something different from what the user perceives, thus potentially revealing confidential information or allowing others to take control of their computer while clicking on seemingly innocuous objects, including web pages. Clickjacking is an instance of the confused deputy problem, wherein a computer is tricked into misusing its authority.The Confused Deputy rides again! Tyler Close, October 2008 History In 2002, it had been noted that it was possible to load a transparent layer over a web page and have the user's input affect the transparent layer without the user noticing.

Websites
A website (also written as a web site) is a collection of web pages and related content that is identified by a common domain name and published on at least one web server. Examples of notable websites are Google, Facebook, Amazon, and Wikipedia. All publicly accessible websites collectively constitute the World Wide Web. There are also private websites that can only be accessed on a private network, such as a company's internal website for its employees. Websites are typically dedicated to a particular topic or purpose, such as news, education, commerce, entertainment or social networking. Hyperlinking between web pages guides the navigation of the site, which often starts with a home page. Users can access websites on a range of devices, including desktops, laptops, tablets, and smartphones. The app used on these devices is called a Web browser. History The World Wide Web (WWW) was created in 1989 by the British CERN computer scientist Tim Berners-Lee. On 30 April ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Web Application
A web application (or web app) is application software that is accessed using a web browser. Web applications are delivered on the World Wide Web to users with an active network connection. History In earlier computing models like client-server, the processing load for the application was shared between code on the server and code installed on each client locally. In other words, an application had its own pre-compiled client program which served as its user interface and had to be separately installed on each user's personal computer. An upgrade to the server-side code of the application would typically also require an upgrade to the client-side code installed on each user workstation, adding to the technical support, support cost and decreasing productivity. In addition, both the client and server components of the application were usually tightly bound to a particular computer architecture and operating system and porting them to others was often prohibitively expensive for ...

HTML Element
An HTML element is a type of HTML (HyperText Markup Language) document component, one of several types of HTML nodes (there are also text nodes, comment nodes and others). The first used version of HTML was written by Tim Berners-Lee in 1993 and there have since been many versions of HTML. The most commonly used version is HTML 4.01, which became official standard in December 1999. An HTML document is composed of a tree of simple HTML nodes, such as text nodes, and HTML elements, which add semantics and formatting to parts of document (e.g., make text bold, organize it into paragraphs, lists and tables, or embed hyperlinks and images). Each element can have HTML attributes specified. Elements can also have content, including other elements and text. Concepts Elements vs. tags As is generally understood, the position of an element is indicated as spanning from a start tag and is terminated by an end tag. This is the case for many, but not all, elements within an HTML docume ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
JavaScript
JavaScript (), often abbreviated as JS, is a programming language that is one of the core technologies of the World Wide Web, alongside HTML and CSS. As of 2022, 98% of Website, websites use JavaScript on the Client (computing), client side for Web page, webpage behavior, often incorporating third-party Library (computing), libraries. All major Web browser, web browsers have a dedicated JavaScript engine to execute the Source code, code on User (computing), users' devices. JavaScript is a High-level programming language, high-level, often Just-in-time compilation, just-in-time compiled language that conforms to the ECMAScript standard. It has dynamic typing, Prototype-based programming, prototype-based object-oriented programming, object-orientation, and first-class functions.

Client-side JavaScript
JavaScript (), often abbreviated as JS, is a programming language that is one of the core technologies of the World Wide Web, alongside HTML and CSS. As of 2022, 98% of websites use JavaScript on the client side for webpage behavior, often incorporating third-party libraries. All major web browsers have a dedicated JavaScript engine to execute the code on users' devices. JavaScript is a high-level, often just-in-time compiled language that conforms to the ECMAScript standard. It has dynamic typing, prototype-based object-orientation, and first-class functions. It is multi-paradigm, supporting event-driven, functional, and imperative programming styles. It has application programming interfaces (APIs) for working with text, dates, regular expressions, standard data structures, and the Document Object Model (DOM). The ECMAScript standard does not include any input/output (I/O), such as networking, storage, or graphics facilities. In practice, the web browser or other run ...
