What are the three types of security controls?

The classification of security controls into technical, administrative, and physical controls is essential for understanding how different types of measures can be implemented to protect information systems and data.

Technical controls refer to security measures that are implemented through technology. This can include firewalls, encryption, intrusion detection systems, and access control mechanisms. These controls are designed to protect systems and data from unauthorized access or modification.

Administrative controls involve policies, procedures, and regulations that guide an organization’s security practices. These might include security training, incident response protocols, and risk management frameworks. They help ensure that employees understand their roles regarding security and that best practices are consistently followed.

Physical controls are concerned with the physical protection of assets. This includes measures such as locks, security guards, cameras, and environmental controls that protect hardware and facilities from physical threats like theft, natural disasters, or unauthorized access.

This triad of controls is foundational in the development of a comprehensive security strategy, as it ensures that all aspects of security are covered, from technological solutions to human factors and the physical environment. The other options, while they may refer to relevant aspects of security, do not encapsulate the standard framework or categories that are commonly utilized in security control classifications.
