摘要

非可信内核扩展模块是对操作系统内核完整性安全的重要威胁之一，因为它们一旦被加载到内核空间，将可能任意破坏操作系统内核数据和代码完整性。针对这一问题，提出了一种基于强制访问控制对操作系统内核完整性保护的模型—MOKIP。该模型的基本思想是为内核空间中的不同实体设置不同的完整性标签，然后保证具有低完整性标签的实体不能破坏具有高完整性标签的实体。基于硬件辅助的虚拟化技术实现了原型系统，实验结果表明，本系统能够抵御各种恶意内核扩展模块的攻击，其性能开销被控制在13%以内。

Abstract

Untrusted kernel extensions were considered to be a big threat to OS kernel integrity because once they were loaded into the kernel space

then they may corrupt both the OS kernel data and code at will.To address this problem

MAC-based model named MOKIP for OS kernel integrity protection was presented.The basic idea of MOKIP was to set different integrity labels for different entities in the kernel space

and then ensure that the entities with low integrity label cannot harm the entities with high integrity label.A prototype system based on the hardware assisted virtualization technology was implemented.The experimental results show that proposed system is effective at defending against various malicious kernel extension attacks within a little performance overhead which is less than 13%.
