Fine-grained user-space security through virtualization

  title={Fine-grained user-space security through virtualization},
  author={Mathias Payer and Thomas R. Gross},
This paper presents an approach to the safe execution of applications based on software-based fault isolation and policy-based system call authorization. A running application is encapsulated in an additional layer of protection using dynamic binary translation in user-space. This virtualization layer dynamically recompiles the machine code and adds multiple dynamic security guards that verify the running code to protect and contain the application. The binary translation system redirects all… CONTINUE READING
