WebAbstract. Software Fault Isolation (SFI) consists in transforming un-trusted code so that it runs within a speci c address space, (called the sandbox) and verifying at load-time that the binary code does indeed stay inside the sandbox. Security is guaranteed solely by the SFI veri er whose correctness therefore becomes crucial. WebSFI Unit of Isolation: Fault Domain •SFI confines untrustedcode within a fault domain, in same address space (process) as trusted code •Fault domain consists of: –Unique ID (used for access control on syscalls) –Code segment: virtual address range with same unique high-order bits, used to hold code
