Here are some general steps for using Azure Sentinel Hunting:
- Define your goals: Before you start hunting for threats, you should define your goals and objectives. Determine what you want to achieve with your hunting activities and what types of threats you are looking for.
- Create custom queries: Use Azure Sentinel’s query language to create custom queries that search for specific types of threats and anomalies. Queries can be based on a variety of criteria, such as IP addresses, user accounts, and activity patterns.
- Analyze the data: Once you have created your queries, run them against your organization’s data to identify potential threats and suspicious activity. Use Azure Sentinel’s visualizations and dashboards to gain insights into your data and identify patterns and trends.
- Investigate potential threats: When you identify a potential threat, investigate it further to determine its severity and impact on your organization. Use Azure Sentinel’s incident management features to track and document your investigation.
- Remediate threats: Once you have confirmed a threat, take appropriate action to remediate it. Depending on the severity of the threat, this may involve blocking IP addresses, disabling user accounts, or taking other security measures.
- Share insights and findings: Collaborate with other security analysts to share insights and findings from your hunting activities. This can help to improve the effectiveness of your hunting activities and increase your organization’s overall security posture.
- Continuously monitor for new threats: Hunting for threats is an ongoing process that requires continuous monitoring and analysis of your organization’s data. Regularly review your queries and adjust them as necessary to ensure that you are able to detect new and emerging threats.
Overall, Azure Sentinel Hunting is a powerful tool for proactively detecting and responding to potential security threats. By using custom queries, analyzing data, investigating potential threats, and taking appropriate remediation actions, you can help to keep your organization’s data and systems secure.
