To create a hunt in Microsoft Sentinel, navigate to the Azure portal and access your Sentinel workspace. Under the Threat Management section, select 'Hunting'. Here you can explore built-in hunting queries or create custom ones using Kusto Query Language (KQL).
When creating a new hunting query, you define the query logic, assign a name and description, map it to MITRE ATT&CK tactics and techniques, and specify the required data sources. This helps organize hunts by threat categories and ensures proper data connectivity.
Livestream is a feature that enables real-time hunting sessions. You can start a livestream from any hunting query to monitor results as events occur, which is particularly useful during active investigations or when testing new detection logic.
Bookmarks allow analysts to preserve interesting findings during hunting sessions. When you discover suspicious activities, you can bookmark the results with notes and tags for later investigation. These bookmarks can then be promoted to incidents for formal investigation workflows.
Hunting notebooks powered by Jupyter provide advanced hunting capabilities. These notebooks combine KQL queries with Python code for sophisticated analysis, machine learning models, and custom visualizations.
To manage hunts effectively, organize queries using tags and categories, regularly review and update custom queries based on emerging threats, and track hunting metrics to measure effectiveness. You can also share hunting queries across your team and contribute to the Microsoft Sentinel community.
Best practices include scheduling recurring hunts for persistent threat detection, documenting findings thoroughly, and integrating hunting results with your broader security operations workflows to improve overall threat detection capabilities.
Create and Manage Hunts in Microsoft Sentinel
Why is This Important?
Threat hunting is a proactive security practice that allows Security Operations Analysts to search for undetected threats that may have bypassed automated detection systems. In Microsoft Sentinel, hunts enable analysts to systematically investigate potential security incidents before they escalate into major breaches. This capability is essential for the SC-200 exam as it demonstrates advanced security operations skills.
What is Hunt Management in Microsoft Sentinel?
Hunts in Microsoft Sentinel are structured investigations that allow security teams to: - Create organized threat hunting campaigns - Track hunting hypotheses and their outcomes - Collaborate with team members on investigations - Document findings and evidence - Convert successful hunts into automated detection rules
How Hunts Work in Microsoft Sentinel
Creating a Hunt: 1. Navigate to Microsoft Sentinel in the Azure portal 2. Select Hunting from the Threat Management section 3. Click New Hunt to create a hunting campaign 4. Define the hypothesis, timeframe, and scope 5. Assign team members and set priorities
Managing Hunts: - Use hunting queries (KQL-based) to search for suspicious activities - Bookmark interesting results for further investigation - Add bookmarks to existing incidents or create new ones - Track the status of hunts through their lifecycle - Document outcomes and lessons learned
Key Components: - Hunting Queries: Pre-built or custom KQL queries targeting specific threats - Bookmarks: Saved query results that preserve evidence - Livestream: Real-time query execution for active investigations - Notebooks: Jupyter notebooks for advanced analysis
Exam Tips: Answering Questions on Create and Manage Hunts in Microsoft Sentinel
1. Understand the Hunt Lifecycle: Know the stages from hypothesis creation through resolution and documentation.
2. Know KQL Basics: Questions may involve identifying correct query syntax or understanding query results.
3. Bookmark Functionality: Remember that bookmarks preserve evidence and can be promoted to incidents.
4. Collaboration Features: Understand how hunts enable team collaboration and assignment of tasks.
5. Integration Points: Know how hunts connect with other Sentinel features like Analytics Rules, Incidents, and Workbooks.
6. Scenario-Based Questions: When presented with a threat scenario, identify whether proactive hunting or automated detection is more appropriate.
7. Permissions Required: Understand that hunting requires appropriate RBAC permissions like Microsoft Sentinel Contributor.
8. Common Exam Traps: Distinguish between hunting queries (proactive) and analytics rules (automated detection).
9. Time Management: Hunt-related questions often involve multiple steps - read the entire question before selecting an answer.
10. Remember MITRE ATT&CK: Hunting queries are often mapped to MITRE ATT&CK framework tactics and techniques.
