What is a primary goal of physical security controls?

The primary goal of physical security controls is to prevent unauthorized physical access to sensitive areas and assets. This includes measures such as locks, security guards, biometric scanners, surveillance cameras, and barriers, which are designed to protect a facility and its resources from intrusions or theft. By effectively implementing these controls, organizations help ensure the integrity, confidentiality, and availability of critical infrastructure and data.

The other choices relate to different aspects of cybersecurity and information protection but do not pertain directly to physical security. Encrypting sensitive data focuses on safeguarding information stored digitally, monitoring network traffic involves analyzing data flow for security threats, and performing source code audits is about examining software code for vulnerabilities. Each of these activities plays a vital role in overall cybersecurity but serves different purposes than that of physical access control.
