Access-control

Access control refers to the practice of regulating and managing the entry and usage of resources within a system or environment. It involves the implementation of security measures to ensure that only authorized individuals or entities can gain access to specific areas, data, or services. Access control mechanisms can range from simple methods like username-password authentication to more sophisticated techniques like biometric scans, smart cards, and role-based permissions. The primary goal of access control is to safeguard sensitive information, maintain the integrity of systems, prevent unauthorized activities, and enforce compliance with security policies, thereby enhancing overall security and minimizing potential risks.
