Mobile Device Profiling and Intrusion Detection Using Smart Batteries

This paper introduces capabilities developed for a battery-sensing intrusion protection system (B-SIPS) for mobile computers, which alerts when abnormal current changes are detected. The intrusion detection system´s (IDS´s) IEEE 802.15.1 (Bluetooth) and 802.11 (Wi-Fi) capabilities are enhanced with iterative safe process checking, wireless connection determination, and an automated intrusion protection disconnect ability. The correlation intrusion detection engine (CIDE) provides power profiling for mobile devices and a correlated view of B-SIPS and snort alerts. An examination of smart battery drain times was conducted to ascertain the optimal transmission rate for the B-SIPS client. A 10 second reporting rate was used to assess 9 device types, which were then compared with their corresponding baseline battery lifetime. Lastly, an extensive usability study was conducted to improve the B-SIPS client and CIDE features. The 31 expert participants provided feedback and data useful for validating the system´s viability as a complementary IDS for mobile devices.
