Address each of these threat modeling steps to secure your residential system:
Step 1: Identify security objectives.
Step 2: Identify assets and external dependencies.
Step 3: Identify trust zones.
Step 4: Identify potential threats and vulnerabilities.
Step 5: Document your threat model.
In your post, be sure to explain how physical, logical, and administrative aspects of threats may interact.
