SmartGroup Use Case

The following is an example of using SmartGroups:

Angel creates three SmartGroups:

  • Smart Group 1 = SAP_BW

  • Smart Group 2 = SAP_CRM

  • Smart Group 3 = Public CIDR of Hosted S4Hana

Angel has the following business objectives:

  • Allow BW and CRM to talk to PaaS endpoint S4Hana on port 443

  • Deny all traffic between BW and CRM

To achieve Distributed Cloud Firewall (DCF) objectives, Angel does the following in Security > Distributed Cloud Firewall:

  • Builds firewalling policies that allow traffic from Smart Group 1 and 2 to talk on port 443 to Smart Group 3.

  • Creates a Deny All Policy for Smart Group 1 to talk to Smart Group 2. Note that after a SmartGroup is part of a policy, all traffic for that SmartGroup is denied unless explicitly allowed by DCF rules.
