The present invention facilitates mapping dependencies between software applications, components, and business processes on a computer network. Packets communicated between software applications are sampled to identify characteristics of the packet. The characteristics are used to identify communicating applications and to generate dependency maps of software applications on a computer network.

Method and system for non intrusive application interaction and dependency mapping

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

The present invention facilitates identifying applications based on communicated packets between applications. Characteristics of communicated packets are used to identify the packet as being part of a communication between applications. Identification can be accomplished through the use of packet fingerprints or through a K nearest neighbor algorithm.

Method and system for automatic classification of applications and services by packet inspection

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.

Method and system for verifying a client request

A method for detecting security vulnerabilities in a web application includes analyzing the client requests and server responses resulting therefrom in order to discover pre-defined elements of the application's interface with external clients and the attributes of these elements. The client requests are then mutated based on a pre-defined set of mutation rules to thereby generate exploits unique to the application. The web application is attacked using the exploits and the results of the attack are evaluated for anomalous application activity.

System for determining web application vulnerabilities

The present invention is a security gateway system positioned between an external, untrusted computing environment and an internal, trusted computing environment that converts messages received from the external environment into simplified messages and converts the simplified messages into messages suitable for use on the internal environment. The conversion involves the removal of external environment transfer protocols and the reduction of the content of the messages left after removing the protocols into a simplified representation of the content to create a simplified message. The simplified representation is then converted to an internal message by converting the simplified representation to a representation appropriate to the internal environment, including to applications operating on the internal environment, and adding internal environment protocols, including transfer protocols, to the converted message. Simplified representations exist for some but not necessarily all types of content which may be received from the external environment, thus limiting the content which may be passed from the external to the internal environment.

Method and system for protecting operations of trusted internal networks

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 &ldquo;stage&rdquo; 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.

A method for protecting an operating environment on a processor from a rogue program operating on the processor comprising isolating simultaneously executing programs or operating systems is disclosed. Memory space for use only by the first program while the first program is executing is allocated. Communication between the first program and the computer's operating environment is accomplished through a single link employing one of several methods including using shared memory space, a dedicated interrupt or a dedicated I/O port. The monitor manages a restricted operating environment for the first program on the processor, the restricted operating environment preventing the first program from accessing resources on the processor except for the allocated memory space the single communication link.
