Which control is focused on reducing the risk of loss through specific security measures?

The focus of the question is on controls that specifically aim to reduce the risk of loss through security measures, which aligns perfectly with technical risk controls. Technical controls consist of security mechanisms and safeguards implemented through technological solutions. These include firewalls, intrusion detection systems, encryption, and access control mechanisms. Such controls are designed to protect the integrity, confidentiality, and availability of information by reducing vulnerabilities and threats in technological environments.

Operational controls, while important, pertain more to processes and procedures that support day-to-day operations and maintaining security policies rather than directly implementing technical security measures. Management controls involve the governance and oversight aspects of security practices, including risk assessments and policy enforcement, focusing on the broader organizational framework rather than specific technical implementations. Physical security controls address the physical protection of facilities, equipment, and resources, which, while crucial for overall security, do not primarily deal with the technical measures that specifically aim to mitigate risks through technology. Thus, technical risk controls are indeed the most appropriate choice in this context for actively minimizing risk through targeted security implementations.
