Cisco Umbrella Top 1M Domains List

This app helps with providing guidelines for installing Cisco Umbrella Top 1M Domains List app in Trisul Network Analytics.

To create a Domain Topper Counter that can be used in NSM to train the spotlight on least common domains seen in your network traffic.

Some of the uses can be

  1. Visibility - To know the usage patterns outside the Top-1M in your enterprise.
  2. Detect Outliers - To detect rare domains, those created by DGA, typically used by malware.
  3. Iterative - To add white-list based on your enterprise and fine tune this list.
Added Quantcast-Top-1M to this as well. So any domain that is not in either of the lists can be truly said to be outside Top-1M
