Abstract
Methods, systems, and computer program products are provided for hardware enforced data protection mechanisms to protect software data structures. Software data structures can be protected against malicious software or software code errors that may result in data/buffer overruns or failures in computing systems. Software data structures are identified that need to be validated before they are used by software programs. A hardware mechanism receives instructions from various security privilege levels and validates an entire software data structure before the software data structure is used by software programs. Being able to detect whether a software data structure is corrupted improves defenses and security against malicious or erroneous code, provides a method for early identification, isolation, ease of debugging of software, and protects overall system integrity in computer systems and applications thereof.
