What are the roles of network policy management in access control?

Policy management plays a crucial role in maintaining access control within network environments. It involves defining, implementing, and enforcing policies that determine who has access to what resources within the network. By setting clear rules and guidelines through policy management, organizations can ensure that only authorized users have access to specific data or systems, helping to prevent unauthorized access, breaches, and data leaks. Effective policy management also enables consistent enforcement of security protocols and compliance with regulations, thereby enhancing overall network security and risk management.
