Security cameras and alarm systems are considered technical controls in the context of information security. Technical controls, also known as logical controls, involve the use of technology to protect information and information systems. These controls are designed to prevent or detect security breaches and mitigate risks related to physical access and surveillance. While security cameras and alarms are physical in nature, they fall under the broader category of technical controls because they involve electronic monitoring and alert systems. Option B (Managerial) refers to administrative policies and procedures, and option C (Legal) refers to controls related to compliance with laws and regulations, neither of which applies in this case.
