Network Access control
Network Access Control (NAC) sits within the larger field of cybersecurity, and more specifically network security. It is a technology that enables organizations to enact its own unique policy for how and when endpoints (desktops, laptops, smartphones, etc.) can connect to their corporate networks. NAC solutions are typically designed to allow IT security teams to gain visibility of each device trying to access its network, and specifically the type of device and access layer being used (i.e. wifi, wired ports, or VPN).
Why is Network Access Control Important?
Network access control delivers a host of benefits to the organizations that deploy it. Generally speaking, the value unlocked by NAC can be broken into three distinct areas of focus:
One of the most interesting aspects of NAC is the fact that unlike many other areas of network security, it brings more than just the value of security to the table. In particular, NAC delivers three core operational values:
- Device Onboarding – Properly connecting and removing new non-managed devices to/from the network;
- Guest / Contractor Access – Securely granting limited access for third-parties connecting to the network, either for short or long periods of time;
- Asset Profiling – Identifying which devices exist in your organization and where they are connecting from.
The importance of network security goes without saying. Network access control, however, checks the boxes for a variety of IT security best practices, including:
- WiFi Security – Nearly 20% of SMBs experience a data breach by a former employee who still has WiFi access…make sure you can control all WiFi connections
- Visibility – See all devices on your network – no matter device type, location, or access layer used to connect
- Containment – The ability to quarantine, block, or provide limited (guest) access to endpoints that do not meet your internal risk policies
- Asset Profiling – see above.
Highly regulated industries like banking, financial services, and healthcare require strict compliance policies when it comes to their networks. NAC helps to deliver this and more through:
- Posture Assessment – Continually assess the risk posture of connecting devices across the network, no matter location or access layer
- Port / Wired Security – Ensuring no un-trusted device can physically connect to the network via wired ports in the office
- Segmentation – Properly directing employees into their respective departmental VLANs, or pushing visitors to the guest network
- WiFi Security – see above.
