METHODS AND APPARATUS FOR A SAFE AND SECURE SOFTWARE UPDATE SOLUTION AGAINST ATTACKS FROM MALICIOUS OR UNAUTHORIZED PROGRAMS TO UPDATE PROTECTED SECONDARY STORAGE

Described herein are articles, systems, and methods for using a storage controller to protect secure data blocks through the enforcement of a read only policy. In some embodiments, the articles use a combination of hardware protections and software protections (e.g., virtualization) to protect a system against attack from malware while such secure data is updated. Also described are systems and methods for securely updating data blocks secured in this fashion, and detecting and preventing the corruption of data stored on secondary storage media using a disk eventing mechanism.
