Solution By Steps

Step 1: Identify Physical Security Measures

Physical security measures are actions or devices designed to protect a physical space and its contents from unauthorized access or harm.

Step 2: Evaluate Each Option

Changing locks to ensure key control: This is a physical security measure as it controls access to the home.

Confirming that a cleaning company is reliable and licensed: This is a security measure but more related to vetting service providers rather than direct physical security.

Hiding a key outside to ensure family members can get in if they lose their keys: This is not a secure practice as it can easily allow unauthorized access.

Discuss the importance of monitoring internet acquaintances with family members: This is a digital or personal safety measure, not a physical security measure.

Having good relations with neighbors and looking out for each other: This is a community-based security measure, enhancing overall safety but not a direct physical security device or action.

Step 3: Determine the Non-Physical Security Measure

Among the options, discussing the importance of monitoring internet acquaintances with family members is not a physical security measure.

Final Answer

The option that is NOT a physical security measure for your home is “Discuss the importance of monitoring internet acquaintances with family members.” This is more related to digital or personal safety rather than physical security of the home.
