When dealing with security solutions, data collection primarily refers to the harvesting of real-time and historical data, which can later be examined to find risks, analyze patterns, and formulate security strategies.
Microsoft offers several solutions that help in optimizing data collections, such as Microsoft 365 Defender, Microsoft Defender for Endpoint, Microsoft Defender for Identity, and Azure Defender. These powerful tools provide an extensive variety of logs and data sources that can be harnessed for analysis and proactive security measures.
Configuring Data Collections in Microsoft Defender for Endpoint
To configure data collections in Microsoft Defender for Endpoint, the key aspect is setting up a data retention policy which determines the duration for which data will be stored.
- Navigate to the ‘Settings’ page under the ‘Advanced features’ section.
- Click on the ‘Data Retention’ tab.
- Specify the number of days you wish to retain the data (30-180 days).
- Click on ‘Save preferences’.
Configuring Data Collections in Microsoft 365 Defender
In Microsoft 365 Defender, you can view and manage data through the Microsoft 365 security center. Here, you can adjust the parameters associated with data storage, sharing and usage information.
- Go to the navigation pane and select ‘Settings’.
- Choose ‘Services & add-ins’ then ‘Microsoft 365 Defender’.
- Configure data privacy settings according to the organization’s preference.
- Save your changes.
Configuring Data Collections in Azure Defender
Configuring data collections in Azure Defender involves setting up Log Analytics to pull data from your applications and network infrastructure. Here’s how you do it:
- In the Azure portal, select ‘Create a resource’ and then ‘Log Analytics workspace’.
- Fill in the required details and select the appropriate ‘Pricing tier’.
- After the Log Analytics workspace is set up, navigate to ‘Azure Security Center’.
- Under the ‘Data Collection’ section, select the ‘Log Analytics workspace’ you created.
- Choose ‘Save’.
Data collected through Azure can include System Security Event Logs, Firewall Logs, Linux audit logs, Windows event logs and more.
Comparison of Data Collections
| Feature | Microsoft Defender for Endpoint | Microsoft 365 Defender | Azure Defender |
|---|---|---|---|
| Event data | Endpoint security logs | Office 365 audit logs, Exchange logs | Azure infrastructure logs |
| Retention period | 30-180 days | Depending on license | Depending on license and needs |
| Type of data | Endpoint-related data | Office 365 related data | Infrastructure data |
In conclusion, configuring data collection in these Microsoft tools involves more than just simple collection but extends to establishing retention periods, selecting sources and types of data, and managing privacy settings. By understanding and configuring these settings correctly, a Security Operations Analyst is better equipped to guard against potential cyber threats and breaches. In doing so, they fulfill crucial aspects of SC-200 Microsoft Security Operations Analyst Exam, proving their competencies in ensuring a secure environment for data-driven operations.
