Managerial controls are designed to establish security policies, procedures, and guidelines within an organization. They help in the strategic alignment of security practices with business operations and in ensuring that organizational security objectives are met. They are essential for the governance of security within the company.

Technical controls, on the other hand, involve the use of technology to enforce security measures, such as firewalls and encryption. Operational controls are more about implementing and maintaining day-to-day security tasks. Physical controls include tangible measures like locks, biometrics, and surveillance systems.
