A Web portal or public portal refers to a Web site or service that offers a broad array of resources and services, such as e-mail, forums, search engines, and online shopping malls. The first Web portals were online services, such as AOL, that provided access to the Web, but by now most of the traditional search engines have transformed themselves into Web portals to attract and keep a larger audience. A web portal is most often one specially designed Web page which brings information together from diverse sources in a uniform way. Usually, each information source gets its dedicated area on the page for displaying information (a portlet); often, the user can configure which ones to display. Variants of portals A portal may use a search engine API to permit users to search intranet content as opposed to extranet content by restricting which domains may be searched. Apart from this common search engines feature, web portals may offer other services such as e-mail, news, stock quotes, information from databases and even entertainment content. Portals provide a way for enterprises and organizations to provide a consistent look and feel with access control and procedures for multiple applications and databases, which otherwise would have been different web entities at various URLs. The features available may be restricted by whether access is by an authorized and authenticated user (employee, member) or an anonymous site visitor. Examples of early public web portals were AOL, Excite, Netvibes, iGoogle, MSN, Naver, Lycos, Indiatimes, Rediff, and Yahoo!. The main concept is to present the user with a single web page that brings together or aggregates content from a number of other systems or servers. The application server or architecture performs most of the crucial functions of the application. This application server is in turn connected to database servers, and may be part of a clustered server environment. High-capacity portal configurations may include load balancing strategies. For portals that present application functionality to the user, the portal server is in reality the front piece of a server configuration that includes some connectivity to the application server. For early web browsers permitting HTML frameset and iFrame elements, diverse information could be presented without violating the browser same-source security policy (relied upon to prevent a variety of cross-site security breaches.) More recent client-side technologies rely on JavaScript frameworks and libraries that rely on more recent web functionality such as WebSockets and async callbacks using XMLHttpRequests. The server hosting the portal may only be a "pass through" for the user. By use of portlets, application functionality can be presented in any number of portal pages. For the most part, this architecture is transparent to the user. In such a design, security and concurrent user capacity can be important issues, and security designers need to ensure that only authenticated and authorized users can generate requests to the application server. If the security design and administration does not ensure adequate authentication and authorization, then the portal may inadvertently present vulnerabilities to various types of attacks. 1.
