Access Control
Access Control is a fundamental security concept that governs how users, systems, or processes are granted or denied access to resources such as data, applications, or networks. It involves defining and enforcing policies to ensure that only authorized entities can perform specific actions, protecting against unauthorized use, modification, or disclosure. This is implemented through mechanisms like authentication, authorization, and auditing to maintain confidentiality, integrity, and availability in computing environments.
Developers should learn and implement Access Control to secure applications and systems, especially in scenarios involving sensitive data, multi-user platforms, or compliance requirements like GDPR or HIPAA. It is critical for preventing data breaches, ensuring privacy, and managing user permissions in web applications, cloud services, and enterprise software, where fine-grained control over resource access is necessary for operational security.
