Which type of device is often used to monitor access and enforce security policies in an organization?

Access control systems are specifically designed to monitor and manage access to physical or digital resources within an organization, enforcing security policies effectively. These systems can include mechanisms such as card readers, biometric scanners, keypads, and software that logs access attempts, providing a detailed audit trail. By using these devices, organizations can determine who has access to specific areas or information and can enforce rules regarding that access, such as time restrictions or user permission levels.

In contrast, IoT sensors are primarily used for data gathering and monitoring environmental conditions but do not inherently enforce security policies related to access. Network switches manage and direct traffic within a network but lack the access control capabilities of dedicated access control systems. Routers, on the other hand, facilitate network connectivity and can provide some level of security through firewalls or access control lists, but they are not tailored to monitor or enforce access policies in the same comprehensive manner as access control systems do.
