Specifically, we present ZLeaks, a tool that passively identifies in-home devices or events from the encrypted Zigbee traffic by 1) inferring a single application layer (APL) command in the event’s traffic, and 2) exploiting the device’s periodic reporting pattern and interval. In this work, we analyze the privacy guarantees of Zigbee protocol. Zigbee is an energy-efficient wireless IoT protocol that is increasingly being deployed in smart home settings. The evaluation results show that IoT-DeepSense achieves a high behavioral detection rate of 92%, with negligible impact on the performance of IoT devices. The design and implementation of IoT-DeepSense are carried out on an independent Internet of things behavior detection server, without modifying the limited resources of IoT devices, and have strong scalability. IoT-DeepSense constructs the real operating environment of the IoT device system to capture the fine-grained system behaviors and then leverages an LSTM-based IoT system behavior abnormality detection approach to effectively extract the hidden features of the system’s behavior sequence and enforce the security detection of the abnormal behavior of the IoT devices. Aiming at this issue, we propose IoT-DeepSense, a behavioral security detection system of IoT devices based on firmware virtualization and deep learning.

Therefore, how to obtain complex security behaviors and states inside IoT devices and perform security detection and defense is an issue that needs to be solved urgently. Meanwhile, network-based traffic detection is difficult to obtain the internal behavior states and conduct in-depth security analysis because more and more IoT devices use encrypted traffic.

However, due to the limited memory and battery power of IoT devices, it is hardly possible to install traditional security software, such as antivirus software for security defense. Recently, IoT devices have become the targets of large-scale cyberattacks, and their security issues have been increasingly serious. The evaluation results suggest that HoMonit can effectively validate the working logic of SmartApps and achieve a high accuracy in the detection of SmartApp misbehaviors. To evaluate the effectiveness of HoMonit, we analyzed 181 official SmartApps and performed evaluation on 60 malicious SmartApps, which either performed over-privileged accesses to smart devices or conducted event-spoofing attacks.

To detect anomaly, HoMonit compares the SmartApps activities inferred from the encrypted traffic with their expected behaviors dictated in their source code or UI interfaces. To address these problems, this paper leverages side-channel inference capabilities to design and develop a system, dubbed HoMonit, to monitor SmartApps from encrypted wireless traffic. The previous research has revealed several security flaws in the design of SmartThings, which allow malicious smart home apps (or SmartApps) to possess more privileges than they were designed and to eavesdrop or spoof events in the SmartThings platform.
Our research revolves around Samsung SmartThings, a smart home platform with the largest number of apps among currently available smart home platforms. Smart home is an emerging technology for intelligently connecting a large variety of smart sensors and devices to facilitate automation of home appliances, lighting, heating and cooling systems, and security and safety systems.
