What is meant by "access control" in security management?

"Access control" in security management refers to the practice of regulating who can enter specific areas or access particular resources, thereby enhancing safety and security. This concept is crucial in various settings, such as workplaces, facilities, and events, where it is necessary to determine who is allowed in specific locations to prevent unauthorized entry and to protect people and property.

Effective access control systems can include physical measures, such as locks and security personnel, as well as electronic systems, like keycards or biometric scanners. By controlling access, security personnel can mitigate risks, manage emergencies, and maintain order, ensuring that only authorized individuals have the ability to access sensitive or restricted areas.

The other options do not accurately encompass the primary function of access control. Monitoring company currency and finances relates more to financial management rather than physical security. Ensuring that security guards are adequately trained pertains to personnel management, while controlling access to technology systems only is a narrower scope that doesn't capture the broader application of access control in physical spaces.
