Eclypsium researchers Jesse Michael and Mickey Shkatov discuss their research in this recorded webinar. DMA attacks enable a potential attacker to read and write memory off a victim system directly, bypassing the main CPU and OS. Hardware-based root of trust and chain of trust schemes are necessary but not sufficient protection, they say. A layered, defense-in-depth approach should extend these technologies to detect and respond to new threats and vulnerabilities, they write. The research shows that many devices with built-in hardware protections continue to be vulnerable.”]
