Abstract
Mechanisms have been developed for securing computational systems against certain forms of attack. Taint status for data accessible by processes is selectively maintained and propagated in correspondence with information flows of instructions executed by a computing system, so that a security (or other appropriate) response can be provided if and when a control transfer (or other restricted use) is attempted based on tainted data. One response that may be triggered is a change in the privilege level (root and guest) that is used to process code executing in a virtual environment, so as to allow remediation to be performed. The triggering events may be specified in a control block.
