Abstract
A system inserts at least one notifying identifier in the computer system. The at least one notifying identifier provides execution information associated with the computer system. The system receives execution information from the at least one notifying identifier, the execution information identifies details associated with a traffic flow on the computer system. The system then generates a signature based on a deterministic link provided by the execution information provided by the at least one notifying identifier. The signature is utilized to prevent further damage caused to the computer system by at least one attack.
Claims20
A method of providing computer security on a computer system, the method comprising:
- inserting at least one notifying identifier in the computer system, the at least one notifying identifier providing execution information associated with the computer system;
- receiving execution information from the at least one notifying identifier, the execution information identifying details associated with a traffic flow on the computer system;
- and
- generating a signature based on a deterministic link provided by the execution information provided by the at least one notifying identifier, the signature utilized to prevent further damage caused to the computer system by at least one attack.
A computerized device comprising:
- a memory;
- a processor;
- a communications interface;
- an interconnection mechanism coupling the memory, the processor and the communications interface;
- wherein the memory is encoded with a signature generating application that when executed on the processor is capable of providing computer security on the computerized device by performing the operations of:
- inserting at least one notifying identifier in the computer system, the at least one notifying identifier providing execution information associated with the computer system;
- receiving execution information from the at least one notifying identifier, the execution information identifying details associated with a traffic flow on the computer system;
- and
- generating a signature based on a deterministic link provided by the execution information provided by the at least one notifying identifier, the signature utilized to prevent further damage caused to the computer system by at least one attack.
A computer readable medium encoded with computer programming logic that when executed on a process in a computerized device provides computer security, the medium comprising:
- instructions for inserting at least one notifying identifier in the computer system, the at least one notifying identifier providing execution information associated with the computer system;
- instructions for receiving execution information from the at least one notifying identifier, the execution information identifying details associated with a traffic flow on the computer system;
- and
- instructions for generating a signature based on a deterministic link provided by the execution information provided by the at least one notifying identifier, the signature utilized to prevent further damage caused to the computer system by at least one attack.
