Web Browser

A web browser is a software application for viewing webpages. Microsoft Internet Explorer, Mozilla FireFox, Opera, and Apple Safari are the most common web browsers.

A safer browser has the following characteristics:

► Latest version

► Automatic software patches and upgrades

► Anti-phishing functionality to notify you when you try to access a suspected fake website

► 128-bit encryption that protects data during transmission

HTTP (HyperText Transfer Protocol) is a protocol used to send data over the internet. HTTPS (HyperText Transfer Protocol using Secure Socket Layer) is a protocol that encrypts data to send it over the internet more safely. When you enter a URL into a browser, the address will begin with either HTTP or HTTPS

SSL (Secure Sockets Layer) is a secure communications protocol used by browsers, websites, and applications to protect information sent over the internet. SSL protocol uses encryption and authentication technologies to make sure only the intended parties can read the information.

Goal of question This question will determine if the applicant is well versed in the terminology used in web security. The applicant needs to be able to articulate highly technological topics to a wide audience. The second question will help to verify that the applicant fully understands how XSS attacks work and the impact to client information.

Microsoft Internet Explorer usually has the fastest startup time on Microsoft Windows machines, although this is mostly because the real "price" of starting it up is paid during the booting of your Microsoft Windows system,Opera is the fastest browser in terms of placing minimal demands on an older computer. Firefox is a very fast descendant of Mozilla, well-tuned for real-world browsing experiences, with an interface that speeds up the way you get things done in a web browser by offering features like tabbed browsing and a more elegant "find" feature -- another relevant kind of speed

hose "spyware detected" and similar messages that appear on specific web pages on top of the actual content are ads.

An attack technique that forces a web site to echo client-supplied data, which execute in a users web browser. When a user is Cross-Site Scripted, the attacker will have access to all web browser content (cookies, history, application version, etc). XSS attacks do not typically directly target the web server or application, but are rather aimed at the client. The web server is merely used as a conduit for the XSS data to be presented to the end client. See also "Client-Side Scripting".

In computing, a hyperlink (or link) is a reference to a document that the reader can directly follow, or that is followed automatically. The reference points to a whole document or to a specific element within a document. Hypertext is text with hyperlinks. Such text is usually viewed with a computer. A software system for viewing and creating hypertext is a hypertext system. To hyperlink (or simply to link) is to create a hyperlink. A user following hyperlinks is said to navigate or browse the hypertext.

Opera is a web browser and Internet suite developed by the Opera Software company. The browser handles common Internet-related tasks such as displaying web sites, sending and receiving e-mail messages, managing contacts, chatting on IRC clients, downloading files via BitTorrent, and reading Web feeds. Opera is offered free of charge for personal computers and mobile phones.

Safari is a web browser developed by Apple. First released as a public beta on January 7, 2003 on the company's Mac OS X operating system, it became Apple's default browser beginning with Mac OS X v10.3 "Panther." Safari is also the native browser for the iPhone OS. A version of Safari for the Microsoft Windows operating system, first released on June 11, 2007, supports Windows XP, Windows Vista, and Windows 7. The current stable release of the browser is 4.0.4 for both Mac OS X and Windows.

Netscape's web browser was once dominant in terms of usage share, but lost most of that share to Internet Explorer during the first browser war. By the end of 2006, the usage share of Netscape browsers had fallen, from over 90% in the mid 1990s, to less than 1%. Netscape developed the Secure Sockets Layer Protocol (SSL) for securing online communication, which is still widely used, as well as JavaScript, the most widely-used language for client-side scripting of web pages.

Mozilla Firefox is a free and open source web browser descended from the Mozilla Application Suite and managed by Mozilla Corporation. A Net Applications statistic put Firefox at 24.41% of the recorded usage share of web browsers as of January 2010, making it the second most popular browser in terms of current use worldwide after Microsoft's Internet Explorer, and the most used browser independent of any one operating system. Other sources put Firefox's usage share at between 21% and 32% and generally trending upward.

In web browsers, a plug-in (also called plugin, addin, add-in, addon, add-on, snap-in or snapin) consists of a computer program that interacts with a host application (a web browser or an email client, for example) to provide a certain, usually very specific, function "on demand". Add-on is often considered the general term comprising plug-ins, extensions, and themes as subcategories.
