An Architectural Approach to Preventing Code Injection AttacksAdded by Papergrl
Description:
Code injection attacks, despite being well researched, continue to be a problem today. Modern architectural solutions such as the NX-bit and PaX have been useful in limiting the attacks, however they enforce program layout restrictions and can often times still be circumvented by a determined attacker. We propose a change to the memory architecture of modern processors that addresses the code injection problem at its very root by virtually splitting memory into code memory and data memory such that a processor will never be able to fetch injected code for execution.
