Power states in power-scalable systems are managed to maximize performance and reduce energy waste. Power-scalable processor capabilities (e.g., Intel Turbo Boost) embrace a "faster is better" approach to power management. While these technologies can vastly improve performance and energy efficiency, there is a growing body of evidence that "faster is not always better". For example,...
Recently, "rootkit" becomes a popular hacker malware on the Internet, which controls the hosts on the Internet by hiding itself, and raises a serious security threat. Existing host-based and hardware-based solutions have some disadvantages, such as hardware overhead and being discovered by root kits, where the development of virtualization technology provides a better solution to avoid those...
System call interposition is a powerful method for regulating and monitoring program behavior. A wide variety of security tools have been developed which use this technique. However, traditional system call interposition techniques are vulnerable to kernel attacks and have some limitations on effectiveness and transparency. In this paper, we propose a novel approach named VSyscall, which leverages...
