ACCESS CONTROL SYSTEM
Access control is a security technique that regulates who or what can view or use resources in a computing environment. It is a fundamental concept in security that minimizes risk to the business or organization.
There are two types of access control: physical and logical.
Physical access control limits access to campuses, buildings, rooms and physical IT assets.
Logical access control limits connections to computer networks, system files and data.
To secure a facility, organizations use electronic access control systems that rely on user credentials, access card readers, auditing and reports to track employee access to restricted business locations and proprietary areas, such as data centers. Some of these systems incorporate access control panels to restrict entry to rooms and buildings, as well as alarms and lockdown capabilities, to prevent unauthorized access or operations.
