Abstract

Consumer devices are increasingly being used to perform security and privacy critical tasks. The software used to perform these tasks is often vulnerable to attacks, due to bugs in the application itself or in included software libraries. Recent work proposes the isolation of security-sensitive parts of applications into protected modules, each of which can only be accessed through a predefined public interface. But most parts of an application can be considered security-sensitive at some level, and an attacker that is able to gain in-application level access may be able to abuse services from protected modules.
