Partial abstract: “ In this paper, we propose a new security metric showing strong correlation between ‘popular paths’ and kernel vulnerabilities. We verify that the OS kernel paths accessed by popular applications in everyday use contain significantly fewer security bugs than less-used paths. We then demonstrate that this observation is useful in practice by building a prototype system which locks an application into using only popular OS kernel paths. By doing so, we demonstrate that we can prevent the triggering of zero-day kernel bugs significantly better than three other competing approaches, and argue that this is a practical approach to secure system design.”
