Description: Application access control refers to the policies and technologies that restrict access to specific applications, ensuring that only authorized users can interact with them. This mechanism is fundamental in information security, where applications are often hosted in shared environments and accessible over the Internet. Key features of access control include authentication, which verifies the user’s identity, and authorization, which determines what resources a user can use once authenticated. Additionally, role-based access control (RBAC) policies can be implemented, where permissions are assigned based on the user’s role within the organization. The relevance of access control lies in its ability to protect sensitive data and comply with security regulations, preventing unauthorized access that could lead to data breaches or cyberattacks. In a world where security threats are becoming increasingly sophisticated, application access control becomes a critical line of defense for organizations operating in various environments.
