Abstract: We propose a lightweight network access control (NAC) technique applied to wireless router. It authenticates users and devices whether they are trusted or not and it controls the access of the devices according to their security state. As the age of internet of things and bring your own device has begun, NAC technique has become more important. However, it is hard to adopt the NAC from small and medium sized enterprise because of the cost problem. For this reason, we suggest lightweight NAC on wireless router. To do this, we developed an advanced NAC module added to OpenWrt, open source wireless router firmware, which allows to establish secure network environment without additional NAC appliance. We also developed agent programs for PC and mobile to examine the security state of device and identify the trusted users and devices.

Keywords: network access control; lightweight NAC; wireless routers; internet of things; IoT; bring your own device; BYOD; authentication; network security; trust; trusted users; trusted devices.
