KASR: A Reliable and Practical Approach to Attack Surface Reduction of Commodity OS Kernels [chapter]

Zhi Zhang, Yueqiang Cheng, Surya Nepal, Dongxi Liu, Qingni Shen, Fethi Rabhi
2018 Lecture Notes in Computer Science  
In this paper, we propose a reliable and practical system, named KASR, which transparently reduces attack surfaces of commodity OS kernels at runtime without requiring their source code.  ...  For a real-world use case (e.g., an Apache Server), many kernel services are unused and only a small amount of kernel code is used.  ...  In summary, we make the following contributions: • Propose a new approach to reliably and practically reduce the attack surfaces of commodity OS kernels. • Design and implement a practical KASR system  ...
