Network Access Control (NAC)

Security policies that regulate device access to a network.

Understanding:

Network Access Control (NAC) is a security framework that restricts unauthorized devices from accessing a network based on predefined policies. NAC solutions enforce authentication and compliance checks before granting access.

Common Applications and Use Cases:

Used to prevent unauthorized devices from connecting to corporate networks.
Enforces endpoint compliance, ensuring devices meet security requirements before access.
Helps detect and isolate compromised or infected devices.

Best Practices and Security Considerations:

Implement role-based access control (RBAC) with NAC policies.
Regularly update device authentication policies to align with security best practices.
Integrate NAC with threat intelligence systems to detect anomalous behavior.
