Ensuring data integrity
Organizations can ensure data integrity by implementing various measures and best practices throughout the entire data life cycle:
- Use data validation checks to ensure that data is accurate, complete, and consistent. This includes format validation, range checking, and consistency checking.
- Use data encryption to protect it from unauthorized access, tampering, or theft.
- Establish access controls to ensure that data is only accessible to authorized individuals. Implement user authentication and role-based access controls and use of firewalls and intrusion detection systems.
- Maintain audit trails to track changes to data and ensure that data is being used appropriately. This involves logging user activity, recording data modifications, and regularly reviewing audit logs.
