Preventing Execution of Unauthorized Native-Code Software
2017
The business world is exhibiting a growing dependency on computer systems, their operations and the databases they contain. Unfortunately, it also suffers from an ever growing recurrence of malicious software attacks. Malicious attack vectors are diverse and the computer-security industry is producing an abundance of behavioral-pattern detections to combat the phenomenon. This paper proposes an alternative approach, based on the implementation of an attested, and thus trusted, thin-hypervisor. Secondary level address translation tables, governed and fully controlled by the hypervisor, are configured in order to assure that only pre-whitelisted instructions can be executed in the system. Thi…
Enforcing trust for execution-protection in modern environments

The business world is exhibiting a growing dependency on computer systems, their operations and the databases they contain. Unfortunately, it also suffers from an ever growing recurrence of malicious software attacks. Malicious attack vectors are diverse and the computer-security industry is producing an abundance of behavioral-pattern detections to combat the phenomenon. Modern processors contain hardware virtualization capabilities that support implementation of hypervisors for the purpose of managing multiple Virtual-Machines (VMs) on a single computer platform. The facilities provided by hardware virtualization grant the hypervisor control of the hardware platform at an effective privil…
