Inadequate data access control can have devastating effects on businesses, as seen in the case of Verizon's data breach in 2017. Implementing ideal data access control measures, such as role-based access control and multi-factor authentication, can significantly reduce the risk of data breaches and unauthorized access. By controlling who has access to sensitive data, organizations can enhance security, improve compliance, improve operational efficiency, increase accountability, and better manage risks. A comprehensive data access control framework is essential for maintaining trust, staying competitive, and supporting efficient operations and compliance.
