Access Control for Network Security Devices

NAC, meaning Network Access Control, is an advanced cybersecurity measure regulating which entities gain access to which specific network resources. Beyond traditional security parameters, NAC enforces specific access policies, ensuring only compliant devices and authorized users. Network access control, or NAC, solutions support network visibility and access management through policy enforcement on devices and users of corporate networks. Identifies devices attempting to connect. Policies may be based on authentication, endpoint configuration. Upgrading from password- to certificate-based authentication with a Public Key Infrastructure (PKI) significantly strengthens NAC frameworks.
