For instance, if the operating system is responsible for the separation between processes and the operating system itself gets compromised, the security guarantees are void. Thus, we additionally require security of the operating system. After explaining the threat model for operating system security, we proceed by classifying recording audio, and/or capturing video. Implemented security measures can ensure these devices don’t become the weak link in your home protection. 1.
