Hardening the OpenBSD Hypervisor (vmd)

Date: 2023-05-20
Time: 14:30–15:15
Room: DMS 1110
Level: Intermediate

Hypervisors provide a unique attack surface for exploit developers, often with a big payoff. The most common exploit route involves finding and exploiting bugs in emulated or paravirtualized devices. This talk will look at experimental approaches to isolating emulated devices in OpenBSD's vmd(8) hypervisor in conjunction with recent mitigations incorporated into the kernel and compare the design with other systems like bhyve and QEMU.


The following slides have been made available for this session:
