Chapter 5: Setting Up Network Access Control
5. Setting Up Network Access Control
5.1 Initiating Network Asset Discovery
Before Veri-NAC can check your assets, it must first find them on your network. All you have to do is press a button and VeriNAC will discover assets on its own. To ensure Veri-NAC finds all assets, be sure all assets are powered on before you initiate the
discovery process.
Different types of Black Box appliances can detect and protect varying amounts of network devices on varying numbers of subnets:
