What is data access control and why is it important?
Data access control is used to manage access to a company’s data by allowing access to authorized database users and restricting access to unauthorized internal and external individuals. If used correctly, it offers a variety of business benefits, including increased efficiency of data analytics, data governance, data-rich application development, and compliance, and quicker results and value derived from sensitive data.
-
What is fine-grained access control?
Fine-grained access control is a method of managing data access that uses specific and different policies to restrict access at the row-, column-, and cell-level, ensuring that sensitive information is thoroughly protected when large amounts of data are stored together. With fine-grained access control, each data point has a unique access control policy, making protection measures more precise and allowing data with varying regulatory requirements to be securely stored and used together.

What’s the difference between RBAC, ABAC, and PBAC?
- RBAC permits or restricts data access based on the privileges associated with a user’s role within an organization. Privileges can only be changed or added if a new role is created.
- ABAC is more dynamic. It permits or restricts data access based on a variety of independently provisioned and environmental characteristics, such as assigned user, action, and environmental attributes.
- PBAC only looks at contextual and environmental factors. PBACs are complex, dynamic, and easily changeable. This approach is an essential tool for compliance with core data regulations that require sensitive data use to have a clear and intended ‘purpose.’
