A new technical paper titled “Interstellar: Fully Partitioned and Efficient Security Monitoring Hardware Near a Processor Core for Protecting Systems against Attacks on Privileged Software” was published by researchers at KAIST.
The paper states “The existing approaches to instruction trace-based security monitoring hardware are dependent on the privileged software, which presents a significant challenge in defending against attacks on privileged software itself. To address this challenge, we propose Interstellar, which introduces a partitioned hardware near the CPU’s main core and leverages the benefit of hardware-level security monitoring. Interstellar is fully partitioned, parallelized, and simultaneously detecting security monitoring hardware.”
