Security Threats in Web-Powered Databases and Web Portals

It is a strongly held view that the scientific branch of computer security that deals with Web-powered databases (Rahayu & Taniar, 2002) than can be accessed through Web portals (Tatnall, 2005) is both complex and challenging. This is mainly due to the fact that there are numerous avenues available for a potential intruder to follow in order to break into the Web portal and compromise its assets and functionality. This is of vital importance when the assets that might be jeopardized belong to a legally sensitive Web database such as that of an enterprise or government portal, containing sensitive and confidential information. It is obvious that the aim of not only protecting against, but mostly preventing from potential malicious or accidental activity that could set a Web portal’s asset in danger, requires an attentive examination of all possible threats that may endanger the Web-based system.
