Understanding Access control system
Means to ensure that access to assets is authorized and restricted based on business and security requirements related to logical and physical systems. These systems implement identification, authentication, and authorization mechanisms to verify user identity and determine appropriate access rights. Access control systems are required by regulations like GDPR, HIPAA, and PCI DSS, and are core components of security frameworks like ISO 27001 and NIST 800-53. Modern implementations include biometric verification, multi-factor authentication, and zero-trust architectures. For example, a healthcare organization might implement role-based access controls ensuring only authorized physicians can access specific patient records based on their department. Related terms: Authentication, Authorization, Principle of least privilege, Identity and Access Management.
