Automate Host Discovery with Asset Tagging

Let’s assume you know where every host in your environment is. Wasn’t that a nice thought? The reality is probably that your environment is constantly changing. Knowing is half the battle, so performing this network reconnaissance is essential to defending it.

Tag, you’re mapped!

A common use case for performing host discovery is to focus scans against certain operating systems. This can be done a number of ways in QualysGuard, historically via maps or light scans followed by a manual workflow. Today, QualysGuard’s asset tagging can be leveraged to automate this very process. By dynamically tagging hosts by their operating system, one can split up scanning into the following:

  1. Frequent light scans that update QualysGuard with the current mapping of your network via dynamic asset tags.
  2. Targeted complete scans against tags which represent hosts of interest.

We step through how to set up your QualysGuard to do exactly this below.
