In today’s digital landscape, Distributed Denial of Service (DDoS) attacks have become a prevalent threat to businesses and applications. These attacks can disrupt services, cause downtime, and lead to significant financial and reputational damage. Microsoft Azure offers robust DDoS protection solutions designed to safeguard your applications and ensure business continuity. In this blog, we will explore Azure DDoS Protection, its features, and how to implement it effectively for your applications.

Understanding DDoS Attacks

DDoS attacks overwhelm a target with a massive volume of traffic, rendering it unavailable to legitimate users. These attacks can take various forms, including:

1. Volumetric Attacks: Flood the network with excessive traffic.
2. Protocol Attacks: Exploit vulnerabilities in network protocols.
3. Application Layer Attacks: Target specific applications or services.

Introduction to Azure DDoS Protection

Azure DDoS Protection provides comprehensive defense against DDoS attacks. It comes in two tiers: DDoS IP Protection and DDoS Network Protection

  • DDoS IP Protection: DDoS IP Protection is a pay-per-protected IP model. While DDoS IP Protection and DDoS Network Protection share the same fundamental technical capabilities, DDoS IP Protection will offer additional value-added services such as cost protection, discounts on WAF, and DDoS quick response support.
  • DDoS Network Protection: By combining application design best practices with Azure DDoS Network Protection, you can protect yourself against DDoS attacks with improved DDoS mitigation capabilities. Within a virtual network, it is automatically adjusted to assist safeguard your unique Azure resources.

  2. Search “DDoS”. When DDoS protection plan appears in the search results, select it.
  3. Select Create.
  4. Enter/ select Subscription, Resource group, Name & Region for DDoS Protection Plan and Create

Enable for an existing virtual network

Option 1

  1. In the Search resources, services box located at the top of the Azure portal, type the name of the virtual network for which you wish to activate DDoS Network Protection. Choose the virtual network name that shows up in the search results.
  2. Select DDoS protection, under Settings.
  3. Click on Enable. Choose the DDoS protection plan you made in previously or an existing one, then click Save under DDoS protection plan. The plan you choose must be linked to the same Microsoft Entra tenant, although it may be in a different subscription than the virtual network.

Option 2

  1. Using the Search resources, services box at the top of the Azure portal, type “DDoS protection plans” into the search field. Choose DDoS protection options when you see them in the search results.
