Network access control (NAC) technology has been around for nearly two decades, but a new generation of NAC solutions is helping organizations keep up with today’s ever-expanding attack surface, delivering not only visibility of the network environment, but also enforcement and dynamic policy control. Modern NAC solutions provide users with enhanced visibility into the IoT devices on their corporate networks, whether they're connecting from inside or outside the network, and can automatically respond to compromised Internet of Things (IoT) devices or anomalous activity.
Modern NAC solutions also provide a clear view into network assets to support regulatory certifications and security best practices that require organizations to establish and maintain an accurate inventory of all connected devices, including IoT—even in virtual environments where assets are constantly connecting and disconnecting from the network. NAC’s monitoring and response capabilities are especially critical since many IoT devices open users to additional risk via compromised, poorly written and un-patchable software, unadvertised back doors hardwired into firmware, and other factors.
NAC solutions are an important part of a Zero Trust Network Access model for security, in which trust is no longer implicit for users, applications, or devices attempting to access the network, and for which IT teams can easily know who and what are accessing the network, as well as how to protect corporate assets both on and off the network.
How NAC Secures Your Network
NAC solutions provide visibility over everything connected to the network, as well as the ability to control those devices and users, including dynamic, automated responses. NAC is part strengthening overall network security infrastructure.
A properly functioning NAC solution can deny access to noncompliant users or devices, place them in quarantine, or restrict access to a small number of network resources, separated from the rest of the network. NAC solutions generally support the following:
Authentication and authorization of users and devices
The growth of insecure or unknown devices attaching to the network, along with a host of breaches due to stolen credentials, has stretched trust beyond the breaking point. Network administrators must adopt a zero-trust approach to network access. Fortinet Network Access solutions offer the necessary device security to see and control all devices and users across the entire network. With proactive protection, organizations can ensure their networks are secure from the latest threats.
IoT Endpoint and Device Protection
Identify and secure unknown IoT endpoint and devices entering the network. Integrated endpoint visibility, control, and advanced protection ensure organizations are secure.
Identity and Access Management
Identify users entering the network with high reliability. Secure authentication is key in the implementation of an effective security policy—many of today’s most damaging security breaches have been due to compromised user accounts and passwords. These breaches have been exacerbated by users with inappropriate levels of access.
