Simple Access Control Lists
Simple Access Control Lists (ACLs) are a basic authorization mechanism that defines permissions for users or groups on resources like files, directories, or network objects. They specify who can read, write, or execute resources, often implemented in operating systems (e.g., Unix/Linux file permissions) or applications to manage access rights. This concept provides a straightforward way to enforce security policies by listing allowed or denied actions for specific entities.
Developers should learn Simple ACLs when building or maintaining systems that require granular access control, such as file systems, web applications, or network services, to prevent unauthorized access and ensure data security. Use cases include setting file permissions in Linux (e.g., chmod commands), configuring user roles in databases, or implementing basic authorization in APIs where simple, rule-based access is sufficient without complex policies.
