Secure IVSHMEM: End-To-End Shared-Memory Protocol with Hypervisor-CA Handshake and In-Kernel Access Control
In-host shared memory IVSHMEM enables high-throughput, zero-copy communication between virtual machines, but today's implementations lack any security control, allowing any application to eavesdrop or tamper with the IVSHMEM region. This paper presents Secure IVSHMEM, a protocol that provides...
An In-Kernel Forensics Engine for Investigating Evasive Attacks
Over the years, adversarial attempts against critical services have become more effective and sophisticated in launching low-profile attacks. This trend has always been concerning. However, an even more alarming trend is the increasing difficulty of collecting relevant evidence about these attack...
