![]() ![]() You can change this setting as you see appropriate. The default setting is to run the query every 2 hours and lookup data from the last 2 hours. After you click on “Create rule” navigate to Set rule logic and make sure the query scheduling is convenient for you. Let’s create a rule using the rule template. For more information, please refer to the tutorial on Tutorial: View and configure Azure DDoS Protection diagnostic logging | Microsoft Learn To ensure that the logs are being collected, make sure that diagnostic logging is enabled on your IP resource. Note: The analytic rules analyze Azure diagnostic logs for public IPs. Under Rule templates, search for DDoS Attack IP Addresses and you will find the 2 new analytic rules. Review the deployment and click on create.Īfter successfully deploying the solution, navigate to your Microsoft Sentinel workspace and click on Analytics. ![]() Provide the required information such as subscription, resource group and workspace. Identifies IP addresses that generates maximal traffic rate over 10k PPS during DDoS attack. Identifies IP addresses that generate over 5% of traffic during DDoS attack. The solution will install a data connector for ingesting Azure DDoS Protection diagnostics logs into Microsoft Sentinel, and two analytic rules which are the main part of this new solution:ĭDoS Attack IP Addresses - Percent Threshold You can deploy the Azure DDoS Protection solution using the following Azure marketplace link: ![]() Azure Firewall blocks the attacking source IP addresses from accessing the data.The adversary, who created a smokescreen with DDoS attack, tries to access resources in the virtual network to steal sensitive data.Azure Firewall is ready to remediate next phases of adversary lifecycle.Microsoft Sentinel derives the attacking source IP addresses from the logs, and triggers Azure Firewall Remediation-IP Playbook.When it detects the attack, it emits log signals to Microsoft Sentinel. Azure DDoS Protection always monitors attacks on the protected resources.He starts by flooding the customer application with a DDoS attack to create havoc, using DDoS as a smokescreen for the next attack vector. An adversary uses a bad bot to launch a multi-vector attack campaign.Remediation of adversaries in Azure Firewallīelow figure describes how the solution works and what steps are taken from attack detection to remediation. In future, we plan to extend the solution to remediate attackers in Azure WAF for organizations that wish to protect their web applications. The solution also supports third party firewalls that offer a Sentinel Playbook for IP remediation. Azure Firewall offers remediation by preventing bad actors from accessing and stealing sensitive data in the protected application. Then, we’ll describe the solution components, the new alert rules we’ve created to pinpoint adversaries, and how to leverage Azure Firewall as an example of remediation. We will provide an example use case covered by this solution. The new solution uses Azure DDoS Protection logs to pinpoint offending DDoS sources and to block them from launching other, sophisticated attacks, such as data theft. In this announcement, we introduce the new Azure DDoS solution for Microsoft Sentinel. We always look for better ways for our customers to achieve more from Azure DDoS Protection and Microsoft Sentinel. Specifically, customers can correlate DDoS smokescreen attacks with events from different sources to detect advanced attacks, such as data theft, and to automatically block them. Microsoft Sentinel and Azure DDoS Protection services offer rich integration to easily ingest DDoS Protection logs and view and analyze this data in Sentinel to create custom alerts and improve their security posture, investigation, and response processes. By overwhelming the targeted website or application with a large amount of traffic, the attackers can exploit vulnerabilities and steal sensitive information.Ĭustomers use Azure DDoS Protection services to safeguard their applications hosted in Azure against DDoS attacks. The crown jewel is using DDoS attacks as a smokescreen to conceal data breaches while the attention is directed to the attack. While DDoS attacks are commonly used to take down critical systems, applications, and infrastructure, they also serve adversaries for extortion and political or ideological motives. Cybercriminals demonstrate increasingly sophisticated tactics using DDoS attacks as multi-purpose tool. ![]()
