Access Control
Access control is a security mechanism that regulates who or what can view, use, or interact with resources in a computing environment. It enforces policies that grant or deny permissions based on user identity, role, or other attributes.
Zero Trust
Zero Trust is a security framework that requires all users, devices, and applications to be verified, authenticated, and continuously validated before being granted access to resources, regardless of whether they are inside or outside the network perimeter.
