Abstract
Various mechanisms are disclosed for protecting the security of memory in a computing environment. A security layer can have an encryption layer and a hashing layer that can dynamically encrypt and then dynamically hash sensitive information, as it is being loaded to dynamic memory of a computing device. For example, a memory unit that can correspond to a memory page can be processed by the security layer, and header data, code, and protect-worthy data can be secured, while other non-sensitive data can be left alone. Once such information is secured and stored in dynamic memory, it can be accessed at a later time by a processor and unencrypted and hash checked. Then, it can be loaded back onto the dynamic memory, thereby preventing direct memory access attacks.
