Embodiments of the present invention provide a method, system and computer program product for directional optimization of policy statements for a Web service. In an embodiment of the invention, a method for directional optimization of policy statements in a policy document can be provided. The method can include loading a policy document referenced for a Web service, extracting a policy from the policy document, and determining whether the extracted policy is bi-directional or direction agnostic. A single run time presentation for the extracted policy can be created when the extracted policy is direction agnostic. Otherwise, separate run time presentations can be created for each direction of the extracted policy when the extracted policy is bi-directional.

Directional optimization for policy evaluation

A system for automating the recovery of a credential store, in which client software generates a temporary key pair based on a new password, and sends client information including the user's name, the public half of the temporary key pair, and the host name of the client computer system to a server system, from which the client information is passed to a recovery process. The client software process displays a prompt indicating that the user should call a help desk. A help desk administrator verifies the user's identity and approves the user's request by causing an approval message to be sent to the recovery process. The recovery process obtains recovery information consisting of either the decryption key(s) for the credential store, or a decrypted copy of the credential store, and encrypts the recovery information using the temporary public key. The client process downloads the recovery information from the server, and decrypts it using private key of the temporary key pair. The credential store can then be decrypted using the recovery information if necessary, then re-encrypted based on the new password. The encrypted recovery information is stored on the server and re-used for a certain period of time, after which it is deleted, thus allowing multiple copies of the credential store to be conveniently recovered.

Method and system for automating the recovery of a credential store when a user has forgotten their password using a temporary key pair created based on a new password provided by the user

The present invention provides a method, system, and computer program product for limiting authorization of an executable action to an application session. A method in accordance with an embodiment of the present invention comprises: generating an alert in response to an execution of an action in an application; and allowing a user to temporarily authorize the execution of the action for a current session of the application. The authorization for the execution of the action is removed when the current session of the application ends.
