VMware vRealize Network Insight (vRNI) – Part 5 – Data Flow Analysis & Micro-Segmentation
In the previous articles of this series, we covered the installation (VMware vRealize Network Insight (vRNI) – Part 1 – Installation) and configuration (VMware vRealize Network Insight (vRNI) – Part 2 – Configuration) of vRealize Network Insight, before integrating vRNI with Microsoft Active Directory via LDAP (VMware vRealize Network Insight (vRNI) – Part 3 – Identity & Access Management via LDAP).
In the most recent article (VMware vRealize Network Insight (vRNI) – Part 4 – Application Discovery), we delved into application discovery. We defined four applications via several options – manual creation of an application, as well as automated discovery based on vSphere Tags/Custom Attributes and VM naming conventions.
In this final article of the series, we will explore and analyse the collected data flows of one of the previously defined applications. The goal here is to identify all valid traffic flows required to secure the application utilising the NSX-T Distributed Firewall (DFW). My friends, today we look at micro-segmentation.
