Security Issues in Smart Home and Mobile Health System: Threat Analysis, Possible Countermeasures and Lessons Learned

Security is an important issue in Smart Home Environments. Most especially in situations where smart homes can store and release sensitive data to third parties, which makes data collected within smart environments vulnerable to severe security and privacy abuses. Therefore, identification of these security issues is crucial to taking the appropriate steps towards mitigating them and enhancing the security of the collected data within these homes. This paper focuses its attention on the analysis of the possible security issues in smart home environments, identification of different attacks and vulnerabilities with possible recommendations, and countermeasures to mitigate these threats. Moreover, we applied threat modelling process to our Smart Environment for Assisted Living (SEAL) system identifying the assets and threats to the system and examining how our system can be designed in a more secure way that will guarantee a maximum protection of data transmitted across the system.
