Managing investigations and remediation actions in the Microsoft Action Center is a crucial aspect of the SC-200 Microsoft Security Operations Analyst certification exam. This broad category encompasses several subtopics, including managing instances, alerts, playbooks, and sophisticated hunting.
Handling Incidents
An essential function of the Microsoft Security Operations Analyst is the effective handling of incidents. These can be managed within the Microsoft 365 Defender portal. The incident page provides detailed information about the incident timeline, affected assets, and alerts associated with the incident. Key mitigation actions include:
- Assigning incidents: Assign incidents to the right responders to coordinate the response.
- Tagging incidents: Extra context can be added to incidents via tags, which can be beneficial for tracking or categorization tasks.
- Closing incidents: Once an incident is resolved, it can be closed with explanations of the remediation.
Managing Alerts
Managing alerts is another crucial role for the Security Operations Analyst. Alerts notify teams about suspicious activities detected by Microsoft 365 Defender. Analysts can view all active alerts, understand the severity and category of each alert, and access detailed information about an alert to make proper decisions.
- Assigning alerts: Assign alerts to the appropriate analyst or team.
- Suppression of alerts: Modify alert policies to suppress or control certain types of alerts based on their volume, accuracy or relevance.
The Role of Playbooks
Playbooks are the automated response for a user or device behavior to help streamline remediation. A Playbook’s job is to simplify and automate the common tasks and tools used in incident response.
- Creation of playbooks: Develop playbooks to automate routine and complex tasks.
- Testing of playbooks: Ensure playbooks work as expected by running trial scenarios.
- Modifying playbooks: Based on the results of the testing, adjust and optimize playbooks.
Advanced Hunting
Advanced hunting is a query-based threat-hunting tool that utilises the power of a robust query language to run explorations across your organisation’s data in Microsoft 365 Defender.
- Formulating Queries: Write and test advanced hunting queries.
- Applying Filters: Narrow down information using various filtering methods.
- Exporting Data: Extract data for further external analysis.
The Microsoft Security Operations Analyst role is ideally suited to those with a strong understanding of how to use the Microsoft Action Center to manage investigations and remediation actions. Hands-on experience with the Microsoft 365 Defender portal’s features, including handling incidents, managing alerts, using playbooks, and advanced hunting capabilities, is essential for performing this role effectively.
By mastering these techniques, a Microsoft Security Operations Analyst can significantly scale up the efficiency of their operations, shorten investigation times, and smooth response coordination – thus contributing to improved overall cyber safety.
