With the rise of self-installed home security devices, the important question to ask is how well these devices protect user data. Although home security devices help secure and monitor homes, they can become great sources of forensic evidence. While home security and smart home devices provide convenience and ease of mind for users, their associated data are also increasingly used as forensic evidence in criminal cases.

Home security systems have been growing and are expected to grow to USD 84.4 billion by 2027. Our method can help investigators working on other home security systems, and our findings can further help developers to improve the confidentiality and privacy of user data in home security devices and their applications. We analyzed the network traffic as the user interacts with the system to identify any security or privacy concerns. We investigated the interaction of the security system with the SimpliSafe companion app on both Android and iOS devices. In this paper, we seek to better understand and assess the forensic artifacts that can be extracted, the security and privacy concerns around the use of home security devices, and the challenges forensic investigators might encounter, by performing a comprehensive investigation of the SimpliSafe security system. To date, there is little existing literature on forensic analysis and the security and privacy of home security systems.

While home security devices have become more accessible and can help users monitor and secure their homes, they can also become targets of cyberattacks and/or witnesses of criminal activities, hence sources of forensic evidence. The emergence of the Internet of Things technologies and the increase and convenience of smart home devices have contributed to the growth of self-installed home security systems.
