Methods and apparatus providing security to computer systems and networks

A system provides security to a computerized device by detecting a sequence of related processing operations within the computerized device and recording the sequence of related processing operations in a security history. The system identifies a security violation when a processing operation performed in the computerized device produces an undesired processing outcome that violates a security policy and subsequently detecting attempted performance of at least one processing operation that attempts to produce the undesired processing outcome that violates the security policy and in response, denies operation of the processing operation(s) within the computerized device to avoid violation of the security policy.
