Question

Explain Access control

Answer 1

Explanation:

In the fields of physical security and information security, access control (AC) is the selective restriction of access to a place or other resource[1] while access management describes the process. The act of accessing may mean consuming, entering, or using. Permission to access a resource is called authorization.

Answer 2

Access control is a security technique that regulates who or what can view or use resources in a computing environment. ... 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.

Three access control paradigms organize how people gain access: role-based access control (RBAC), discretionary access control (DAC), and mandatory access control (MAC).
