Final answer:
Database control measures focus on data integrity, confidentiality, and availability. The three primary types of access control are Discretionary Access Control (DAC), Mandatory Access Control (MAC), and Role-Based Access Control (RBAC). These controls are vital for protecting sensitive information and ensuring data security.
Step-by-step explanation:
Database Control Measures and Types of Access Control
When discussing database control measures, we specifically focus on how to ensure data integrity, confidentiality, and availability in a database system. Access control is a critical aspect of database security and involves restricting access to data and database management features to authorized users. Below are the three types of access control:
- Discretionary Access Control (DAC): This type controls access based on the identity of the user and their permission. In DAC, owners or administrators of the protected system, data, or resource decide who is allowed to access certain resources, defining the policies for access.
- Mandatory Access Control (MAC): In this model, access decisions are based on regulated government classifications. It assigns classifications to both users and data, and the system enforces the access constraints. You could think of this as setting up strict access rules that cannot be altered by users.
- Role-Based Access Control (RBAC): RBAC assigns access based on the roles within an organization. Users are granted access rights depending on their role, and therefore what responsibilities and tasks they need to complete. This is a widely adopted access control mechanism that simplifies management and administration.
It's essential for organizations to apply these controls to protect sensitive information from unauthorized access and breaches, ensuring data security and compliance with various regulatory standards.
