A method and computer program for automatically and continually extracting application protocols (i.e., defining a set of allowable or authorized actions) for any application. The method involves receiving a message from a server before it is sent or in parallel with sending to a client. The message may be in response to a specific request for it from the client. The program then extracts the application protocol data from the server message. Working with a copy of the message, the program strips off the communications protocol(s) from the message and parses the remaining message to identify user-selectable options contained in the message such as commands, fields, etc. These items represent the set of allowable or authorized user actions for the particular 'stage' of the current version of the application as set forth in the message. The set of allowable user actions is then stored by the extraction program in a protocol database accessible to a gateway or filter module.

Method and system for extracting application protocol characteristics

A system and method are presented for authorizing execution of requested actions transmitted between clients and servers of a data processing system. The method includes receiving a message including a set of actions and simulating execution of the set of actions. A list representing allowable actions and user-definable inputs to the simulated actions is defined. The list of allowable actions and user-definable inputs to the allowable action is then compared to user-requested actions and inputs. When elements within the user-requested actions and inputs are included in the allowable actions and input list, the user-requested actions and inputs are authorized for execution.
