Study Notes
Access Control Mechanism
- The system validates the user with the database based on provided credentials/identification, such as password, fingerprint, etc.
- The system then allows the user to perform only those operations or access only those resources for which the user has been authorized.
- Once the identification is successful, the system provides the user access to use the system.
- The correct sequence of steps involved in the access control mechanism is: A user provides their credentials/identification while logging into the system, the system validates the user with the database, the system provides the user access to use the system, and the system allows the user to perform only authorized operations or access resources.
Access Control Elements
- An object is an explicit resource on which an access restriction is imposed.
- A reference monitor verifies the restrictions imposed on objects based on certain access control rules.
Access Control Principles
- The principle of separation of duties (SoD) ensures that no single individual has the authorization rights to perform all functions and simultaneously denies access of all the objects to a single individual.
- The need-to-know principle defines that access is provided only to the information that is required for performing a specific task.
Access Control Models
- Mandatory access control (MAC) is a model where access permissions are available based on the access policies determined by the system and are beyond the user control.
- Role-based access control (RBAC) is a model that assigns permissions to a user role dynamically based on a set of rules defined by the administrator.
- Rule-based access control (RB-RBAC) is a model that determines the access control taken by any possessor of an object to decide the access control of a subject on that object.
- Discretionary access control (DAC) is a model where users can amend the access policies created by the system.
