So why would you need a NAC. A NAC represents an emerging category of security products. The goal of a network access control system is to mitigate zero-day attacks, and vulnerabilities, policy enforcement for your assets as well as BYOD over wireless, and identity and access management. While almost all corporations have a firewall, which provides security from the outside in, the NAC works from the inside out.
Mitigation of Zero-Day attacks and Vulnerabilities
NACS have the ability to prevent weak or infected trusted devices from accessing the network and placing other computers within your organization at risk. The NetClarity Next Generation NACWALL enables automated, real-time quarantine of trust assets that become weak and infected. You can find and fix your Common Vulnerabilities and Exposures (CVE’s), hardening your network assets and preempting successful exploitation holes.
Policy enforcement of BYOD over Wireless and using 802.1q VLANS
NetClarity’s NACWALL allow IT staff to define policies, such as the types of computers or roles of users allowed to access areas of the network, and enforce them automatically in all old and new unmanaged and manged switches that support the safer, more stable protocol of 802.1q as opposed to the easily hacked and circumvented 802.1x.
