Access Control

What Is Access Control?

Access control is a security measure that is used to regulate who or what can view or use resources in a computing environment. It is used to prevent unauthorized access to confidential or sensitive information, and to protect the privacy and integrity of data. Access control is typically implemented through the use of authentication, authorization, and encryption. Authentication is the process of verifying the identity of a user or device, while authorization is the process of granting access to resources based on the user's identity. Encryption is the process of encoding data so that it can only be accessed by authorized users.

Description

Access control is a security measure that is used to regulate who or what can view or use resources in a computing environment.

Usage and Examples

Access control is used in a variety of contexts, including physical security, network security, and application security. For example, physical access control systems are used to restrict access to buildings, rooms, and other physical spaces. Network access control systems are used to restrict access to networks and network resources. Application access control systems are used to restrict access to applications and application data. Access control systems can also be used to control access to data stored in databases, cloud storage, and other data repositories.
