Which statement best describes "access control" in security measures?

Access control refers specifically to the systems and procedures implemented to regulate who can enter specific areas or access particular information. This is a fundamental aspect of physical and information security, ensuring that only authorized individuals can enter secured spaces or interact with sensitive data. By establishing restrictions based on user identity, roles, and other criteria, organizations can significantly reduce the risk of unauthorized access, theft, or damage.

The focus on regulating entry to secured areas aligns closely with the core objective of access control, which is to protect assets and maintain the safety and security of a facility or information system. Effective access control measures often include tools such as ID badges, biometric scanners, security gates, and comprehensive security protocols. These strategies contribute to the overall security infrastructure by creating layers of defense against potential threats.
