Best Practices for Responding to Azure AD Security Incidents. Are you responsible for developing a best practices guide for responding to security incidents in Azure Active Directory (AD) within your organization? This article guides you through the process.
To achieve this goal, we delve into six essential steps that aid you in developing a robust incident response plan in advance.
Let’s begin by laying the groundwork with an informative overview section.
What is an Azure Active Directory Security Incident and Why Should You Have a Response Plan?
These alerts provide information about affected assets and prioritize them based on severity. We discuss severity in more detail shortly.
We have clarified what Azure AD security incidents are and the Microsoft tools available for tracking them. The following sections delve into the best practices for responding to Azure AD security incidents.
Step 1: Craft a Comprehensive Guide for Azure AD Incident Response
To develop a security incident response, create an incident response plan. This plan identifies the staff responsible for handling different aspects of an incident.
Furthermore, your plan should outline the Azure Active Directory security incident lifecycle. This encompasses steps like incident identification, reporting and conducting post incident response reviews.
In summary, as outlined in “Inside the MSRC – Building your own security incident response process,” your document should specify the leader of the incident response and clarify the powers and responsibilities of the Azure AD incident response team.
Step 2: Develop a Process for Scoring and Prioritizing Azure AD Security Incidents
The Microsoft Defender for Cloud provides companies with the necessary information to prioritize Azure AD security incidents. Incidents are classified by Severity (High, Medium, Low, and Informational).
To establish an Azure Active Directory security incident scoring and prioritization standard, companies adopt the existing severity system of Microsoft Defender for Cloud. Along with the standard severity definition, your document should include the classification of Azure AD subscriptions.
For instance, it is crucial to classify subscriptions used for production and non production activities. Subsequently, security admins must prioritize alerts based on severity, importance and data sensitivity.
To define an incident scoring and prioritization system, admins also utilize tags for resource organization.
Step 3: Provide Microsoft with Your Security Incident Contact Details
Step 3 is about configuring email notifications in the Microsoft 365 Defender portal.
To configure email notifications in the Microsoft 365 Defender portal, follow these steps:
1. Sign in to defender.microsoft.com.
2. Navigate to Settings, select Microsoft 365 Defender, and click “Email notifications.”
On the “Email Notifications” tab, you have 2 options:
Create a new incident notification rule in the “Incidents” tab. Alternatively, edit the existing “Default incidents notification” rule or use it as is.
Important note: When creating an incident notification rule, you’re required to include the email addresses of all incident recipients. For reference, refer to the second screenshot below.
It is crucial for security admins to include the emails of all individuals responsible for an incident response when creating the incident.

Step 4: Incorporate a Manual and Automated Incident Monitoring and Response into Your Plan
Moreover, as part of the best practices for Azure AD security incident response plan, you seamlessly stream alerts to Azure Sentinel by utilizing the Azure Security Center data connector.
After exporting the security alerts, view them and access recommendations through Azure Monitor.
Incorporating the monitoring of exported alerts and recommendations into your incident response plan proves highly beneficial.
Step 5: Perform a Post Incident Review
Furthermore, a post incident response review examines the incident’s details, causes, and consequences.
It is important to note that the post incident review aims to identify what went wrong and collaborate with all stakeholders to mitigate future incidents.
Step 6: Test Your Azure AD Security Incident Response Plan
To effectively respond to Azure AD security incidents, it is crucial to follow the best practices outlined in this article and create a response strategy. However, the process must be complemented by testing the plan.
The testing process involves simulating a security incident and executing real live responses, as if it were an actual event. By running a “mock” test, you proactively identify potential plan shortcomings and address them beforehand.
Moreover, testing enables all team members to assess the communication plan outlined in the incident response strategy. This step helps identify possible communication failures and team synergy issues, allowing you to rectify them.
Notably, the Microsoft 365 Defender portal offers an “Attack simulation training” tool. With this feature, security admins simulate worst case scenario cyber attacks.
Best Practices for Responding to Azure AD Security Incidents Conclusion
In conclusion, having a well defined response plan for Azure AD security incidents prepares your organization to respond effectively. By following the best practices outlined in this article, you address these incidents (when they occur) and minimize their impact.
The 1 step is to craft a comprehensive guide specifically tailored to Azure AD incident response. This guide serves as a valuable resource for your team, ensuring a swift and coordinated response when Azure security incidents occur.
Next, it is vital to develop a process for scoring and prioritizing Azure AD security incidents. This step allows you to prioritize resource allocations, enabling you to tackle security incidents quickly and minimize their impact on your business.
In addition, providing Microsoft with your security incident contact details is essential. By doing so, your incident response team receive alerts and initiate the incident response plan promptly.
Moreover, incorporating both manual and automated monitoring and response mechanisms into your plan is crucial for enhancing your incident response capabilities. This combination enables real time threat detection, and proactive measures. Hence minimizes the impact of security incidents.
Furthermore, performing a post incident review is equally important. This step allows you to analyse the incident response process, identify areas for improvement, and implement corrective measures to enhance your future incident handling.
Lastly, testing your Azure AD security incident response plan is paramount. By conducting thorough tests, including mock simulations and worst case scenario training, you validate the effectiveness of your plan, identify any shortcomings, and ensure readiness to address real world incidents.
By implementing these best practices and maintaining an agile Azure Active Directory security incident response plan, you strengthen your organization’s resilience against Azure AD security incidents. This safeguards your Azure AD infrastructure and maintain the trust of your stakeholders.
