Web access management (WAM) is a form of identity management that controls access to web resources, providing authentication management, policy-based authorizations, audit and reporting services (optional) and single sign-on convenience
Authentication management is the process of determining a user’s (or application’s) identity. This is normally done by prompting for a user name and a password. Additional methods of authentication can also include access tokens (which generate one-time passwords) and digital certificates.
Once a user's (or process') identity is confirmed, policy-based authorization comes into play. A web resource can have one or more policies attached to it that say "only allow internal employees to access this resource" and/or "only allow members of the Admin Group to access this resource." The requested resource is used to look up the policy, and then the policy is evaluated against the user’s identity. If the user passes the policy evaluation, she/he is granted access to the resource. If the user fails the evaluation, access is denied.
After an authentication or authorization policy decision is made, the outcome can be recorded for auditing purposes, such as:
- determining the last login time of a user
- identifying attempts to gain access to protected resources
- logging any administrative actions
As a benefit to the end user, a web access management product can then tie this security together (which is more of a benefit to IT and administrative staff), and offer single sign on, the process by which a user logs in only once to a web resource, and then is automatically logged in to all related resources. Users can be inconvenienced when attempting to get authenticated to multiple websites throughout the course of a day (potentially each with different user names and passwords). A web access management product can record the initial authentication, and provide the user with a cookie that acts as a temporary token for authentication to all other protected resources, thereby requiring the user to log in only once.

Famous quotes containing the words web, access and/or management:
“The spider spinning his web for the unwary fly. The blood is the life, Mr. Renfield.”
—Garrett Fort (1900–1945)
“The Hacker Ethic: Access to computers—and anything which might teach you something about the way the world works—should be unlimited and total.
Always yield to the Hands-On Imperative!
All information should be free.
Mistrust authority—promote decentralization.
Hackers should be judged by their hacking, not bogus criteria such as degrees, age, race, or position.
You can create art and beauty on a computer.
Computers can change your life for the better.”
—Steven Levy, U.S. writer. Hackers, ch. 2, “The Hacker Ethic,” pp. 27-33, Anchor Press, Doubleday (1984)
“This we take it is the grand characteristic of our age. By our skill in Mechanism, it has come to pass, that in the management of external things we excel all other ages; while in whatever respects the pure moral nature, in true dignity of soul and character, we are perhaps inferior to most civilised ages.”
—Thomas Carlyle (1795–1881)
