Tutorial / Cram Notes
Microsoft Defender for Cloud offers comprehensive threat intelligence reports that allow Security Operations Analysts to understand the threat landscape, identify ongoing attacks, and take the necessary measures to harden their cloud environments against potential threats. The reports combine data from various sources, including Microsoft’s global security intelligence, to give a detailed overview of detected threats, their origins, impacts, and proposed remediation steps.
Analyzing these reports is crucial for maintaining a secure and resilient cloud environment. Here’s how to break down the threat intelligence reports provided by Microsoft Defender for Cloud:
Threat Intelligence Overview
The threat intelligence feature in Microsoft Defender for Cloud provides you with insights into potentially malicious activities by analyzing the security data from your cloud resources. The report includes information about security alerts, compromised resources, and patterns of unusual activities that align with known attack vectors.
Security Alerts
Microsoft Defender for Cloud provides alerts for a variety of potential security issues. The alerts typically include the following details:

- Affected Resources: Details of the resources that are potentially compromised.
- Detected Time: The timestamp when the activity was detected.
- Remediation Steps: Recommendations on how to address the detected threat.
Alert Examples
Let’s look at two example alerts:
- SQL Injection Attack:
- Severity: High
- Affected Resources: Azure SQL Database Instance
- Detected Time: March 15, 2023, at 2:45 PM
- Remediation Steps: Validate input parameters, apply updates, and review database permissions.
- Brute Force Attack:

Advanced Threat Analysis
The reports also include an advanced threat analysis section. This part of the report provides more in-depth insights into the attack tactics, techniques, and procedures (TTPs) used, patterns that may indicate a targeted attack, and further correlation with known threats or actors.
Remediation and Mitigation Strategies
For each alert and identified threat, Microsoft Defender for Cloud provides actionable remediation steps. Typically, the steps could involve applying patches, changing configurations, or adjusting access controls. The platform may also recommend best practices for prevention to avoid the recurrence of similar issues.
Threat Intelligence Examples
A sample analysis of a hypothetical threat intelligence report might reveal the following:
- Threat Name: “ShadowHammer” Campaign
- Severity Level: High
- Attack Technique: Supply Chain Compromise
- Affected Services: Azure DevOps, Azure Functions
Indicators of Compromise (IoCs):
| Indicator | Description |
|---|---|
| Malicious IP | 131.107.xxx.xxx |
| Domain | badactor[.]com |
| Hash Values | a3cce2…cc4ee, 5ebfa1…1dab2 |
Trend Analysis
The reports often include trend analysis, providing insights into the broader threat landscape. This may cover the volume of particular types of attacks, predominant attack vectors, and how the threat landscape is evolving. For example, a surge in ransomware targeting specific cloud services might prompt a change in security strategies.
Customizing Reports
Microsoft Defender for Cloud allows analysts to customize reports to target specific data or time frames. You can configure the reports to focus on certain subscription levels, resource groups, or types of alerts for more detailed analysis.
Reporting and Collaboration
Finally, the threat intelligence reports can be shared with other members of the security team for collaborative analysis. The platform supports exporting reports to common formats such as PDF or CSV for further processing or integration into other tools and dashboards.
By systematically analyzing threat intelligence reports from Microsoft Defender for Cloud, Security Operations Analysts are better equipped to detect, investigate, and respond to threats swiftly, thereby protecting their organization’s cloud-based resources and data.
