How does FortiNAC improve network access control?

FortiNAC enhances network access control primarily by verifying user identity and applying appropriate policies. This process involves authenticating users before allowing them to gain access to the network. By confirming the identity of users and devices, FortiNAC ensures that only authorized individuals and compliant devices can connect. Once verified, it applies security policies specific to those users or devices, which can include restrictions based on roles, device types, and the current security posture.

This approach is critical for maintaining a secure network environment, as it not only helps prevent unauthorized access but also tailors the access rights to each user or device according to predefined security policies. These policies can include actions such as quarantining non-compliant devices, enforcing compliance checks, and limiting access based on the user's role within the organization, thus ensuring a higher level of security.

While other options address components of network management, they do not effectively support the fundamental goal of enhancing network access control in the way that verifying user identity and applying policies does. Bypassing security protocols undermines network integrity, providing unrestricted access poses grave security risks, and limiting the number of devices connected does not inherently improve network access control—it could simply reduce usability without addressing security concerns.
