Network access control is a computer networking solution that uses a set of protocols to define and implement a policy that describes how to secure access to network nodes by devices when they initially attempt to access the network. [3] NAC might integrate the automatic remediation process (fixing non-compliant nodes before allowing access ...
Network Admission Control (NAC) refers to Cisco's version of network access control, which restricts access to the network based on identity or security posture.When a network device (switch, router, wireless access point, DHCP server, etc.) is configured for NAC, it can force user or machine authentication prior to granting access to the network.
PacketFence is an open-source network access control (NAC) system that provides the following features: registration, detection of abnormal network activities, proactive vulnerability scans, isolation of problematic devices, remediation through a captive portal, 802.1X, wireless integration and User-Agent / DHCP fingerprinting.
Once the 60-minute window expires, all network traffic is blocked. The user has the option of re-authenticating with Clean Access again, and continuing the process as needed. Systems passing the checks are granted access to the network as defined by the assigned role on the Clean Access Manager. Clean Access configurations vary from site to site.
IEEE 802.1X is an IEEE Standard for port-based network access control (PNAC). It is part of the IEEE 802.1 group of networking protocols. It provides an authentication mechanism to devices wishing to attach to a LAN or WLAN.
The EX switches support a range of features including high availability and network access control (NAC). The NAC support, which Juniper calls Unified Access Control (UAC), enables the switches to enforce access policies rather than rely on firewalls, VPN gateways, or switches made by other vendors.
The HP IMC Smart Connect includes integrated mobile network–access control to manage enterprise access to mobile devices. [27] To help administrators oversee the use of mobile devices on enterprise networks, HP has integrated into IMC support for the Citrix XenMobile and MobileIron mobile device management applications.
