Web applications manipulate resources in response to requests from users. It is often necessary to determine whether a requested operation should be allowed for the user who sent the request. This process of authorization – that is, deciding whether an application should be allowed to carry.out the operation which a request from a particular user or program calls for – depends on, but is separate from, the process of authentication. Authentication means determining the identity of the user or program sending the request. This is usually done by maintaining user accounts, protected by passwords, and by requiring users to log in.
Written for professional and student Web developers, this book provides a clear and practical description of authentication and authorization for Web sites. Secure methods of storing users’ account details and passwords are described. The authors explain different methods of authentication, and techniques for applying authorization to requests from authenticated users.
