The UMBC Cyber Defense Lab presents
The cybersecurity world faces multiple attack vectors from hardware-level exploits, including cache bank malicious operations, rowhammer, Spectre, Meltdown, and Foreshadow attacks, and software-based attacks including buffer-overflows, et al. Hardware-level exploits bypass protections provided by software-based separation kernels. Current microprocessor execution pipelines are not designed to understand security: they treat malicious instructions, software bugs, and harmless code the same. This presentation explores adding a hardware-level security monitor below the execution pipeline [1,2,3].

About the Speaker. Dr. Jungwirth is a computer architecture researcher at the Army Research Lab. Previously he worked for the Aviation and Missile, RDEC in Huntsville, AL. Currently, he is researching hardware state machines to provide simple operating system support (monitor) and control flow integrity in hardware. Dr. Jungwirth is co-inventor of the OS Friendly Microprocessor Architecture, US Patent 9122610. The OS Friendly Microprocessor Architecture includes hardware security features for an operating system and supports near single-cycle context switches in hardware. Email: *protected email*
