Alerts in Microsoft Security solutions like Microsoft 365 Defender and Azure Sentinel can be triggered by a variety of suspicious activities or detected anomalies. These alerts are generated by various security features such as Microsoft Defender for Endpoint, Defender for Identity, and the Azure Sentinel analytics rules.
To configure alerts, you must:
For example, in Microsoft Defender for Endpoint, you could configure an alert to trigger when a sign of a ransomware attack is detected, such as suspicious file encryption activities.
Incidents in Microsoft security solutions represent a collection of related alerts that might indicate a more significant issue. An incident is designed to streamline investigations and response actions by correlating related alerts into a single entity.
To set up incidents, the steps typically involve:
For instance, you could configure an incident to be generated in Azure Sentinel when multiple alerts related to suspicious login attempts from different geographical locations are detected within a short time frame.
Azure Sentinel provides a feature called Playbooks, which are collections of automated tasks that can be used to respond to alerts and incidents. These tasks are orchestrated using Azure Logic Apps.
When configuring Playbooks to automate responses, consider the following steps:
An example Playbook could be set up to automatically isolate a compromised host from the network when an alert for a confirmed breach is triggered, or to send a notification email to the security operations team.
Once automations are set, it’s crucial to:
By configuring alerts and incidents to trigger automatic responses, security analysts are poised to manage threats proactively. Microsoft Security solutions provide the necessary tools to automate many aspects of the detection and response process, ensuring that security operations teams can focus on more complex tasks that require human intervention. A solid understanding and practical knowledge of these capabilities are essential for aspiring security professionals, especially those looking to pass the SC-200 exam and succeed in the field.
Correct Answer
Explanation: In Microsoft Sentinel, after running a log search that returns the desired results, you can immediately create an alert rule from the query by using the “Create rule” option at the top of the page.
Correct Answer: A, B, D
Explanation: In Microsoft Sentinel, automation rules can include incident creation rules, playbook automation rules to orchestrate a response, and alert suppression rules to reduce noise. Scheduled rules are not a type of automation rule but a type of analytic rule for creating alerts.
Correct Answer
Explanation: You can leverage Azure Logic Apps to create custom workflows that respond to incidents generated by Microsoft Defender for Cloud, thereby automating specific response actions.
Correct Answer: C
Explanation: Playbooks in Microsoft Sentinel are essentially Azure Logic Apps that are designed to automate responses to alerts and incidents when certain conditions are met.
Correct Answer
Explanation: Automation rules in Microsoft Sentinel can be configured to take actions on alerts before they become incidents, as well as directly on incidents that have already been created.
Correct Answer: A, B, C
Explanation: With Microsoft Sentinel, it is possible to automate incident handling actions such as assigning an owner, changing the status, and sending custom email notifications using playbooks. Running a full system backup is typically not an automated response action tied directly to alerts/incidents in Sentinel.
Correct Answer
Explanation: Microsoft Sentinel can apply automation rules to alerts generated by a wide range of security solutions, including Microsoft and non-Microsoft products, provided that their data is being ingested into Sentinel.
Correct Answer: D
Explanation: Microsoft Sentinel enables automation in all phases of alert processing, including generation, triage (e.g., through enrichment or suppression), and incident investigation and handling through playbooks and automation rules.
Correct Answer
Explanation: When an alert’s severity changes in Microsoft Defender for Cloud, you can create an automation rule that triggers a Logic App workflow to perform certain activities in response to the severity upgrade.
Correct Answer: B
Explanation: Incident rules in Microsoft Sentinel are used to configure automated responses as part of the incident handling process.
Correct Answer
Explanation: Automation in Microsoft Sentinel can be triggered without manual intervention by a security analyst. Rules can be set up to automatically respond to specific conditions or indicators associated with alerts and incidents.
Correct Answer: B
Explanation: Azure Logic Apps, when used in conjunction with Microsoft Sentinel, enable automated task execution and workflow orchestration in response to alerts and incidents.
Automation refers to the ability to perform automatic actions in response to alerts and incidents detected by Sentinel.
You can trigger automation in Sentinel by configuring alerts and incidents to execute specific automation actions.
Some examples of automation actions in Sentinel include sending emails, creating or updating tickets in ITSM systems, isolating machines, or running custom scripts.
Automation in Sentinel can help reduce response time, ensure consistent responses, and improve the overall efficiency of security operations.
To configure an alert to trigger automation in Sentinel, you need to create an automation rule that defines the conditions under which the action should be taken.
An automation rule in Sentinel is a set of conditions that determine when an action should be taken in response to an alert or incident.
Some examples of conditions that can be used in automation rules in Sentinel include the severity or status of an alert, the presence of specific tags or labels, or the type of incident.
To create a playbook in Sentinel, you can use the Playbooks page in the Azure portal, which allows you to create new playbooks from templates or from scratch using the Logic Apps Designer.
A trigger in Sentinel playbooks is an event or condition that initiates the execution of the playbook. Triggers can include events from sources such as Azure Activity Logs, Azure Security Center, or other third-party systems.
To migrate a playbook to an automation rule in Sentinel, you can use the Migrate to Automation Rule feature in the Sentinel portal. This feature allows you to convert an existing playbook into an automation rule, which can then be used to trigger actions in response to alerts and incidents.
