Pääsynhallintaperiaatteet

Pääsynhallintaperiaatteet (Access control principles) refer to the fundamental guidelines and concepts that govern how access to resources is managed and secured within a system or organization. These principles are crucial for ensuring that only authorized individuals or entities can access specific information, systems, or physical locations, and that they can only perform actions that are permitted.

A core principle is the principle of least privilege, which dictates that users and processes should be granted only the minimum level of access and permissions necessary to perform their intended functions. This minimizes the potential damage that could occur if an account is compromised or if a user makes a mistake. Another key concept is separation of duties, which involves dividing tasks among different individuals or roles so that no single person has complete control over a critical process. This helps prevent fraud and errors.

Role-based access control (RBAC) is a common implementation of these principles, where access rights are assigned to roles rather than directly to individual users. Users are then assigned to roles, inheriting the permissions associated with those roles. This simplifies management and ensures consistency.

Furthermore, access control relies on authentication, the process of verifying the identity of a user or entity, and authorization, the process of determining what actions an authenticated user is allowed to perform. These principles are essential for maintaining security, confidentiality, integrity, and availability of information and systems in a wide range of environments, from IT networks to physical facilities.
