Recently, when building content for one of my upcoming courses, Microsoft Azure Architect Technologies – Exam AZ-300 , I found the Microsoft documentation wasn’t immediately clear on the exclusivity of Storage Account Firewalls, and Service Endpoints. Do I need to use Service Endpoints and the Storage Firewall together?

This is filtering provided at the network edge by a firewall with rules (ACLs) restricting what internal users are allowed to access. Some firewalls have the ability to filter by an application (layer 7 firewalls), but we’re going to concentrate on standard packet-filtering firewalls and their capabilities.

The problem is that threat actors are able to get through the castle gates (firewalls) and once in, are able to evade the castle guards (IPS). Cisco EPGs can be a physical server, a virtual machine, a Linux container, or even a mainframe. Microsegmentation will fix this. It uses a new construct they call End Point Groups (EPG).
