Azure Sentinel Tutorial
Introduction to Azure Sentinel
Azure Sentinel is a scalable, cloud-native, security information event management (SIEM) and security orchestration automated response (SOAR) solution. It provides intelligent security analytics for your entire enterprise, powered by AI. With Azure Sentinel, you can detect, investigate, and respond to threats across your entire organization.
Setting Up Azure Sentinel
To get started with Azure Sentinel, you first need to set up an Azure account and create a Log Analytics workspace.
Step 1: Sign in to the Azure portal.
Step 2: Create a Log Analytics workspace.
Step 3: Add the Azure Sentinel solution to your workspace.
Connecting Data Sources
Azure Sentinel allows you to connect to various data sources to collect data for analysis. This includes Azure services, on-premises solutions, and third-party applications.
Example: To connect Azure Active Directory logs:
1. Go to Azure Sentinel workspace
2. Click on 'Data connectors'
3. Select 'Azure Active Directory'
4. Follow the prompts to configure the connector
Creating and Managing Alerts
Azure Sentinel enables you to create custom alerts to monitor specific activities or patterns in your data. Alerts can trigger automated responses or notify security personnel.
Example: Creating an alert for suspicious login attempts:
1. Go to Azure Sentinel workspace
2. Click on 'Analytics'
3. Click on 'Create' and select 'Scheduled query rule'
4. Define the query, rule logic, and actions
Incident Investigation
Once Azure Sentinel detects a threat, it generates an incident. You can investigate incidents to understand the threat's impact and scope.
Example: Investigating an incident:
1. Go to Azure Sentinel workspace
2. Click on 'Incidents'
3. Select an incident to view details
4. Use the investigation graph to analyze the incident
Automating Responses
Azure Sentinel allows you to create playbooks to automate responses to specific alerts or incidents. Playbooks are created using Azure Logic Apps.
Example: Creating a playbook to notify the security team:
1. Go to Azure Sentinel workspace
2. Click on 'Playbooks'
3. Click on 'Add playbook'
4. Define the logic for your playbook using Azure Logic Apps
Monitoring and Reporting
Azure Sentinel provides various tools for monitoring and reporting. You can create dashboards to visualize data and generate reports to share with stakeholders.
Example: Creating a dashboard:
1. Go to Azure Sentinel workspace
2. Click on 'Dashboards'
3. Click on 'Add' and select the data to visualize
4. Customize the dashboard and save
Conclusion
Azure Sentinel is a powerful tool for enhancing your organization's security posture. By setting up data connectors, creating alerts, investigating incidents, automating responses, and monitoring continuously, you can protect your environment from a wide range of threats.
