(ISC)2 Certified in Cybersecurity Practice Exam

Which of the following is an example of physical controls in security?

1. Firewalls and antivirus software

2. Identity verification processes

3. Doors and locks

4. Data encryption technologies

The correct answer is: Doors and locks

The example of physical controls in security refers specifically to tangible measures taken to protect physical assets and environments. In this context, doors and locks serve as a fundamental aspect of physical security, creating barriers that physically prevent unauthorized access to facilities, equipment, and sensitive areas. These security measures are designed to protect against physical threats such as theft, vandalism, or unauthorized entry, and they form the first line of defense in any security strategy. Physical controls can include a range of measures, such as fences, walls, barriers, security patrols, and surveillance cameras, but the core premise involves the physical aspects that contribute to securing a location. In contrast, the other options represent different categories of security controls. Firewalls and antivirus software are categorized under technical controls, focusing on protecting information systems and networks from cyber threats. Identity verification processes are part of administrative controls that govern who can access information or physical spaces, while data encryption technologies fall under cryptographic and logical controls aimed at safeguarding data confidentiality and integrity. Therefore, doors and locks stand out as the quintessential example of physical controls.
