DDoS protection is a crucial aspect of cloud security, and Azure offers robust protection against Distributed Denial of Service attacks.
Azure DDoS Protection is a cloud-based service that helps protect against DDoS attacks by detecting and mitigating traffic spikes.
DDoS attacks can overwhelm a network with traffic from multiple sources, causing it to become unresponsive or even crash.
Azure's DDoS Protection can help prevent this by automatically detecting and filtering out malicious traffic, ensuring your network remains available and secure.
By using Azure DDoS Protection, you can safeguard your online presence and prevent costly downtime.
Azure's DDoS Protection is designed to work with your existing network infrastructure, making it easy to integrate and manage.
The service can detect and mitigate traffic spikes in real-time, helping to prevent downtime and data loss.
Azure's DDoS Protection can also help you stay compliant with industry regulations and standards.
What is DDoS Protection in Azure?
DDoS Protection in Azure is a service that helps safeguard your resources from distributed denial-of-service attacks. Azure DDoS Protection offers always-on monitoring and automatic network attack mitigation.
There is no upfront commitment required, and your total cost scales with your cloud deployment. This means you only pay for what you use.
Azure DDoS Protection comes in two tiers: IP Protection and Network Protection. These tiers cater to different security and cost needs.

How to Enable DDoS Protection in Azure
To enable DDoS protection in Azure, you can follow these steps.
First, select Create a resource in the upper left corner of the Azure portal. Then, select Networking, and then select Virtual network. Next, enter or select the following values: subscription, resource group, name, and region.
You can also enable DDoS protection for an existing virtual network by creating a DDoS protection plan and then associating it with the virtual network. To do this, create a DDoS protection plan by completing the steps in Create a DDoS protection plan. Then, enter the name of the virtual network that you want to enable DDoS Network Protection for in the Search resources, services, and docs box at the top of the Azure portal.
Alternatively, you can enable DDoS protection for all virtual networks by using a built-in policy that detects any virtual networks without DDoS Network Protection enabled. This policy can optionally create a remediation task to protect the virtual network.
To enable DDoS protection for a specific virtual network, you can add it to an existing DDoS protection plan. To do this, search for "DDoS protection plans" in the Search resources, services, and docs box at the top of the Azure portal. Then, select the desired DDoS protection plan and add the virtual network to it.
Here are the general steps to enable DDoS protection for a virtual network:
- Create a virtual network or select an existing one.
- Create a DDoS protection plan or select an existing one.
- Associate the DDoS protection plan with the virtual network.
Note that you cannot move a virtual network to another resource group or subscription when DDoS Protection is enabled for the virtual network. If you need to move a virtual network with DDoS Protection enabled, disable DDoS Protection first, move the virtual network, and then enable DDoS Protection.
Configuring DDoS Protection in Azure
Configuring DDoS Protection in Azure is a straightforward process that can be completed in a few steps. You can start by creating a DDoS protection plan, which can be done without any upfront commitment and scales with your cloud deployment.
Azure DDoS Protection offers two tiers: IP Protection and Network Protection, to meet your security and cost needs. You can choose the one that best fits your requirements.
To create a DDoS protection plan, you'll need to select your subscription, resource group, and region. You can also enable DDoS protection on virtual networks in different regions and across multiple subscriptions under a single Microsoft Entra tenant.
Here are the steps to create a DDoS protection plan:
- Select Create a resource in the Azure portal
- Search for DDoS protection plan and select it
- Select Create
- Enter or select the following values:
+ Subscription
+ Resource group
+ Name
+ Region
You can also enable DDoS protection for an existing virtual network by selecting the virtual network, then selecting DDoS protection, and finally selecting Enable.
If you need to move a virtual network to another resource group or subscription, you'll need to disable DDoS protection first, move the virtual network, and then enable DDoS protection again. This is because you can't move a virtual network to another resource group or subscription when DDoS Protection is enabled.
Here are the steps to enable DDoS protection for a virtual network:
- Select Create a resource in the Azure portal
- Select Networking, and then select Virtual network
- Enter or select the following values:
+ Subscription
+ Resource group
+ Name
+ Region
- In the Security pane, select Enable on the Azure DDoS Network Protection radio
- Select the DDoS protection plan you created earlier
You can also enable DDoS protection for multiple virtual networks by adding them to an existing DDoS protection plan.
To add virtual networks to an existing DDoS protection plan, follow these steps:
- Search for DDoS protection plans in the Azure portal
- Select the desired DDoS protection plan
- Select Protected resources under Settings
- Select +Add and select the right subscription, resource group, and virtual network name.
Pricing and Plans
Azure DDoS Protection offers two pricing plans: Basic, which is free, and Standard, which charges per GB of processed data.
Basic DDoS Protection is included at no additional charge, making it a great option for those on a budget.
Standard DDoS Protection is a paid service that charges per GB of processed data, with prices varying depending on the agreement and currency exchange rate.
There are two main plans: Network Protection and IP Protection. Network Protection has a fixed monthly charge, which includes protection for 100 public IP resources, and charges extra for additional resources.
Network Protection is enabled at the virtual network (VNet) level and protects all resource types within the VNet. It also covers scale out costs during a DDoS attack.
Here's a breakdown of the Network Protection pricing:
IP Protection has a fixed monthly charge per public IP resource protected, at $199/month.

Policy Enforcement and Management
Policy Enforcement and Management is a critical aspect of DDoS protection on Azure. Azure DDoS Protection Standard and Premium plans offer built-in policy enforcement and management capabilities.
With Azure DDoS Protection, you can create and manage custom policies to detect and mitigate DDoS attacks. These policies can be tailored to your specific application and network requirements.
Azure's policy management system allows you to easily create, edit, and delete policies, as well as monitor their effectiveness in real-time. This enables you to quickly respond to changing network conditions and stay ahead of potential threats.
Policy Enforcement and Management
Policy Enforcement and Management is a critical aspect of maintaining a secure and compliant organization.
Automated policy enforcement can help reduce the risk of human error, which is estimated to be around 80% of all security breaches.
Regular policy audits can help identify and address compliance issues, reducing the risk of fines and reputational damage.
Policy management software can help streamline the process of creating, assigning, and enforcing policies, reducing administrative burdens and increasing efficiency.
Effective policy enforcement requires a combination of technical controls, such as firewalls and intrusion detection systems, and non-technical controls, such as employee training and awareness programs.
Compliance with regulatory requirements, such as GDPR and HIPAA, can be ensured through the implementation of robust policy management and enforcement processes.
By implementing a robust policy management and enforcement framework, organizations can reduce the risk of security breaches and compliance issues, and maintain a strong reputation in the market.
