【 摘 要 】

Hardware solutions for malware detection are becoming increasingly important as software-based solutions can be easily compromised by intelligent malware. However, the cost of hardware solutions including design complexity and dynamic power consumption cannot be ignored. Many of the existing hardware solutions are based on statistical learning blocks with abnormal features of system calls, network traffics, or processor behaviors. Among those solutions, the performance of the learning techniques relies primarily on the quality of the training data. However, for the processor behavior-based solutions, only a few behavioral events can be monitored simultaneously due to the limited number of PMCs (Performance Monitoring Counters) in a processor. As a result, the quality and quantity of the data obtained from architectural features have become a critical issue for PMC-based malware detection. In this paper, to emphasize the importance of selecting architectural features for malware detection, the statistical differences between malware workloads and benign workloads were characterized based on the information from performance counters. Most malware can easily be detected with basic characteristics, but some malware types are statistically very similar to benign workloads which need to be handled more in-depth. Hence, we focus on multiple steps to investigate critical issues of PMC-based malware detection: (i) statistical characterization of malware; (ii) distribution-based feature selection; (iii) trade-off analysis of detection time and accuracy; and (iv) providing architectural design alternatives for hardware-based malware detection. Our results show that the existing number of performance counters is not enough to achieve the desired accuracy. For more accurate malware detection in real-time, we propose both accuracy improvement schemes (with additional PMCs, etc.) and hardware acceleration schemes. Both schemes provide accuracy improvement (5~10%) and detection speedup (up to 10%) with the additional hardware cost (less than 1% of the chip complexity).
