Researchers at MIT have built a new security measure on top of Intel's Cache Allocation Technology. Dynamically Allocated Way Guard, or DAWG, is built to isolate programs from each other without the performance overhead of Intel's CAT. The technology only requires "minor modifications to the underlying operating system to implement," but unfortunately, it won't protect against all known attacks. The developers say it will mitigate most of them with more development, and hope to see integration of similar systems into future software. The full research paper can be downloaded in the original article.
'We think this is an important step forward in giving computer architects, cloud providers and other IT professionals a better way to efficiently and dynamically allocate resources,' claims lead author Vladimir Kiriansky. 'It establishes clear boundaries for where sharing should and should not happen, so that programs with sensitive information can keep that data reasonably secure.'
