Physical Controls
Physical Controls are security measures designed to protect an organization's physical environment, such as buildings, facilities, and IT infrastructure from theft, damage, or unauthorized access. These controls help ensure the safety and security of critical assets like servers, network devices, and data storage systems by restricting physical access and monitoring the environment. Examples include access control systems like card readers, door locks, security guards, video surveillance cameras, and environmental controls like fire suppression systems and air conditioning. Physical Controls are crucial in safeguarding an organization's information technology infrastructure and reducing the risk of loss or damage due to natural disasters, accidents, or intentional acts of malicious intent.
Guide to Understanding Physical Controls in CISSP Exam
Physical Controls are important aspects of an overall security strategy. They consist of measures taken to protect systems, buildings, and related support infrastructure against threats associated with physical access.

Physical Controls such as locks, badges, and biometric systems help prevent unauthorized physical access to sensitive information. They help protect an organization's assets against theft, tampering, or physical damage.

Physical Controls can be classified into deterrent, preventative, corrective, and recovery controls. Deterrent controls are meant to discourage potential attackers, while Preventative controls are designed to prevent incidents from happening. Corrective controls help to mitigate the impact of an incident, and Recovery controls help restore things back to normal.

Physical controls work by creating a physical barrier between potential attackers and the organization's assets. This can be a locked door, a security guard, or even a wall.
