Build Your Azure Admin Skills with Network Security Groups in Azure Course in Bangalore
The AZ-104: Microsoft Azure Administrator certification is designed for IT professionals responsible for managing cloud services that span storage, networking, and computing.
One of the most tested and essential topics in AZ-104 is virtual networking, which allows communication between Azure resources, the internet, and on-premises infrastructure.
At the heart of Azure’s network security lies the Network Security Group (NSG), your first line of defense.
🛡️ What is a Network Security Group in Azure?
A Network Security Group (NSG) is a filter that allows or denies inbound and outbound traffic to Azure resources. Think of it like a virtual firewall that controls how your virtual machines communicate.
✨ Key Features of NSGs:
- Define rules based on IP addresses, ports, and protocols
- Apply NSGs to subnets or individual network interfaces
- Prioritize rules with custom priorities
- Create stateful connections — responses to allowed inbound traffic are automatically allowed outbound
⚙️ How to Configure a Network Security Group in Azure
Let’s walk through a step-by-step configuration of NSGs using the Azure Portal:
Step 1: Create a Virtual Network
- Go to "Virtual Networks" and click Create
- Define address space and subnets
Step 2: Create an NSG
- Navigate to "Network Security Groups" and click Create
- Assign a Region and Resource Group
- Name your NSG (e.g., web-nsg)
Step 3: Define Inbound/Outbound Rules
- Click on Inbound Security Rules
- Allow SSH (Port 22) for admin access
- Deny other ports unless explicitly needed
- Do the same for Outbound Rules (if required)
Step 4: Associate NSG
- Apply it to a Subnet or a NIC
- Done — Your traffic is now filtered based on your defined rules
💡 Pro Tip: Test rules in a non-production environment first to avoid service disruption.
📘 Real-World Example: NSGs in Action
Priya, an Azure admin at a fintech startup in Bangalore, needed to secure her app backend without exposing sensitive ports. After completing her Microsoft Azure training in Bangalore at Eduleem, she used NSGs to allow only internal traffic to her database subnet and restricted internet exposure completely.
This improved compliance and reduced risk, all without needing additional tools, a clear win using native Azure features.
🎯 Why Learn NSGs with Structured Training?
Setting up NSGs may seem straightforward, but real-world environments require advanced skills like
- Prioritizing rules for multiple services
- Diagnosing traffic flow using NSG Flow Logs
- Integrating NSGs with Azure Firewall or Application Security Groups
That’s why students opt for a hands-on, practical approach through an Azure course in Bangalore taught by cloud professionals.
