Using Microsoft Azure Virtual Network Manager to enhance network security

Nowadays in the digital world, network security is critical to businesses of all sizes. The number of cyber incidents, including all types of attacks, is rising and thus companies require advanced data and infrastructure protection systems.

Microsoft Azure Virtual Network Manager provides a set of tools with which network security can be enhanced, enabling organizations to establish secure and isolated networks in the cloud.

This blog post provides an overview of how Azure Virtual Network Manager helps companies improve their network security resilience. The problem of network security management in the traditional manner.

Traditional model for managing NSGs

Centralized Model

Imagine a castle with a single gatekeeper, who can define all the firewall rules in the Network Security Groups (NSGs).

Such NSGs define what traffic is or is not allowed on and off different parts of the castle. This gives us the benefit of consistency in everything, but changing the strategy for different parts of the castle (flexibility) can be time-consuming as everyone must get approval from the central team.

Decentralized Model

Now each tower has its guards that set their security measures customized for their NSGs. This provides quick responses to local dangers (flexibility), but it also results in unequal defense systems – some battles will have a deep moat and strong NSGs, others with a rickety drawbridge and weak NSGs – thus creating security problems.

Azure Virtual Network Manager

Azure Virtual Network Manager provides an integrated control plane for implementing and enforcing security policies across the entire Azure network architecture.

Group and Manage Virtual Networks

Azure Virtual Network Manager allows you to organize your virtual networks into logical groups based on factors like function (e.g., development, production, DMZ), application type, or regional location.

Consistent Security Policy Enforcement

Establish security baselines (policies) that prevent all high-risk ports and ensure zero-trust concepts. Use these baselines to multiple Network Security Groups (NSGs) at once. This will make sure your network security is consistent across the network.

Hierarchical Security Management

The governance team can set the minimum security policies while the individual application teams can manage the NSG rules as much as they wish, as long as they don’t violate the central policies. It promotes the equilibrium between security and operational effectiveness.
