ACL - Access Controll Lists

Visualizing ACL

What is ACL? An Access Control List (ACL) is a set of rules that defines permissions for accessing resources, ensuring only authorized users or systems can interact with them. ACLs are widely used in file systems, networks, and cloud environments to enhance security by filtering traffic or restricting access based on specific conditions like IP addresses, roles, or actions. They help organizations manage permissions, comply with security standards, and minimize risks by enforcing the principle of least privilege. ACLs are essential for maintaining granular control over sensitive data and systems.
