Preferably, the method also includes identifying when the system is being exploited.

Method of and system for computer system denial-of-service protection

A method of identifying malicious code based on identifying software executing out of writable memory of the computer system. In one embodiment, the identification of the malicious code occurs when the code accesses a predetermined memory address. This address can reside in the address space of an application, a library, or an operating system component. In one embodiment, the access to the predetermined address generates an exception invoking exception handling code. The exception handling code checks the memory attributes of the code that caused the exception and determines whether the code was running in writeable memory.
