DAC

DAC stands for Data Access Control. It is a security mechanism that controls access to data based on user roles and permissions. DAC is used to ensure that only authorized users can access sensitive data. It is an important component of data governance and compliance. DAC can be implemented using various techniques such as access control lists (ACLs), role-based access control (RBAC), and attribute-based access control (ABAC). ACLs are a simple way to control access to data by defining a list of users and their permissions. RBAC is a more complex approach that assigns roles to users and defines permissions based on those roles. ABAC is a dynamic approach that uses attributes to define access policies. DAC is essential for protecting sensitive data and ensuring compliance with regulations such as GDPR and HIPAA.
