Consultant

 

Description: NAC is a combination of IDS (Intrusion Detection System) and IPS (Intrusion Prevention System). The Adapter, developed in Java and Perl, provides an interaction between a NAC (Network Access Controller) by Mirage networks and a third party appliance. This third party appliance can be a vulnerability scanner or a DHCP server. As NAC works only in layers L2 / L3, it will interact with adapter to get information about devices when they enter in to the network. The Adapter takes the help of third party appliance for this information. Vulnerability scanner scans the devices and returns the results to adapter. The vulnerability scanners we used are McAfee’s Foundstone scanner (provides a SOAP API interaction) and Qualys Guard (provides an HTTPS interaction) from Qualys. DHCP server is from Infoblox, a DNSOne appliance.
