Microsoft Azure Network Security Configuration
Service Overview
Service Details
This service provides a complete network security configuration for Azure Virtual Machines. It includes designing and applying Network Security Groups (NSGs) at subnet/NIC level, configuring Azure Firewall or equivalent network firewalls, defining granular allow/deny rules, and enforcing least-privilege access to workloads. The setup can include IP-based, subnet-based, and service-tag-based rules, along with logging, monitoring, and documentation. The goal is to reduce attack surface, block unauthorized access, and ensure that only approved traffic can reach your Azure VMs in a secure and maintainable way.
Available Platforms
Key Benefits
- Reduced attack surface by allowing only necessary inbound and outbound traffic to Azure VMs
- Improved security posture through layered protection with NSGs and firewall rules
- Consistent and auditable access policies aligned with security and compliance standards
- Fewer misconfigurations and downtime caused by ad-hoc or manual rule changes
Use Cases
Securing Public-Facing VMs
Configuring strict NSG and firewall rules for VMs that expose web apps, APIs, or services to the internet, limiting access to only required ports and trusted sources.
Isolating Internal Workloads
Protecting internal application, database, or backend VMs by restricting access to only specific subnets, services, or application tiers within the Azure environment.
Compliance-Driven Network Controls
Implementing standardized network security rules to meet organizational or regulatory requirements, including logging, restricted access, and clear traffic flows.
Post-Migration Hardening
Securing newly migrated VMs from on-premises to Azure by replacing legacy open rules with modern NSG and firewall configurations.
Environment Segmentation (Dev / Test / Prod)
Separating and securing development, testing, and production environments with different access policies to prevent unauthorized or accidental cross-environment access.
