Explain briefly the term access control.

Access control is like a bouncer at a club, deciding who gets in and what they’re allowed to do once inside. It’s a way of managing and restricting entry to systems or resources, whether they’re physical or virtual.

Think of it as a security guard for your computer or network. Access control determines which users can access specific information or use certain resources, and it helps protect against unauthorized access, reducing risks for businesses.

To get in, users usually need to prove their identity through things like passwords, PINs, or even fingerprint scans (like a VIP pass). Multi-factor authentication adds extra layers of security by requiring more than one form of identification.
