Secured Web access

We discuss various secured Web access schemes using dynamic and static approaches. In a static approach the access environment, that is, the set of authorized users, the mode of access, their access rights, etc., are predefined. This approach is suitable only for a static set up where the user requirements do not change frequently. In the dynamic approach, on the other hand, the authorized user set is defined when Web pages access requests appear. An interested user to the Web is authenticated by necessary information provided by the user. Once the information is verified, the user is either given conditional access, timed access, or full access only to the information relevant to the user.
