What security measure controls access to sensitive areas?

Access Control Systems are designed specifically to manage and regulate who has permission to enter sensitive areas, whether those are physical locations or digital spaces. These systems often employ various methods to ensure that only authorized personnel can gain access, which may include key cards, biometric scanners, or password-protected systems.

By utilizing Access Control Systems, organizations can prevent unauthorized access, thereby safeguarding sensitive information and resources from potential threats. This measure is critical in maintaining the security and integrity of highly sensitive areas, ensuring that only individuals with the necessary clearance can enter.

In contrast, the other choices serve different functions in the realm of security. Incident Reporting Systems focus on documenting and addressing security incidents rather than controlling access. Data Encryption Tools protect information by converting it into a coded format, but they do not manage who can access a particular area. Communication Protocols specify the rules for data transmission over networks but do not provide mechanisms for controlling physical or logical access to sensitive areas.
