Various embodiments are generally directed to an apparatus, method and other techniques to determine whether a target address of a register for an execution instruction is valid or invalid based on a comparison between the target address and one or more valid target addresses stored in a storage, increase a number of invalid target addresses if the target address is invalid, and determine whether the number of invalid target addresses is greater than an invalid target address threshold. Various embodiments may also include initiating a security measure to prevent a security breach if the number of invalid target addresses is greater than the invalid target address threshold or executing the execution instruction if the number of invalid target addresses is less than or equal to the invalid target address threshold.

Techniques for detecting false positive return-oriented programming attacks

A processor and method are described for managing different privilege levels associated with different types of program code, including binary translation program code. For example, one embodiment of a method comprises entering into one of a plurality of privilege modes responsive to detecting the execution of a corresponding one of a plurality of different types of program code including native executable program code, translated executable program code, and binary translation program code. In one embodiment, the binary translation program code includes sub-components each of which are associated with a different privilege level for improved security.
