Ang Cui discusses security threats in embedded systems in this video interview.
"His research focuses on embedded devices such as routers, printers and VOIP phones. He is the inventor of a novel, host-based defense mechanism known as Symbiotes. Symbiotes are designed specifically to retrofit black-box, vulnerable, legacy embedded systems with sophisticated anti-exploitation mechanisms. In this video portrait, Ang describes how the extent of the embedded threat in real-world environments, discusses novel exploitation techniques for embedded systems--like enterprise networking equipment--and develops practical defenses for embedded systems that constitute our global communication substrate."
