How to Utilize Azure Logs to Identify Threats: Insights From Microsoft

Microsoft’s Azure platform is a highly acclaimed and widely recognized solution that organizations worldwide are leveraging.

It is regarded as a game-changer in the industry and has emerged as a dependable and efficient platform that helps businesses achieve their goals effectively.

With its robust logging and monitoring tools, Azure offers a comprehensive suite of capabilities designed to detect anomalies, respond to security incidents, and safeguard sensitive data and assets in the cloud.

A recent exploration into the strategies, methodologies, and log analysis techniques by Microsoft’s security experts sheds light on how to effectively utilize Azure Logs to identify and counteract threat actor actions.

At the heart of Azure’s defense mechanism is efficiently comprehending and utilizing logs for threat hunting.

This process is critical in identifying the initial breach and understanding the subsequent actions executed by threat actors.

Microsoft emphasizes integrating best practices for log management, analysis, and incident response to stay ahead of evolving cyber threats.

Microsoft describes a hypothetical attack scenario involving a “Pass the Cookie” assault, where an adversary steals a user’s session cookie to gain unauthorized access to their account.

This example underscores the necessity of vigilant monitoring and analysis of Azure logs to detect such sophisticated attacks.

Log Analysis Techniques

To combat the complexities of cyber threats, Microsoft advocates for using Azure Log Analytics.

This tool plays a pivotal role in investigating security incidents within Azure subscriptions.

By directing both Microsoft Entra ID Audit logs and Azure Activity logs to Log Analytics, organizations can consolidate these logs in the CloudAppEvents table.

At the same time, Log Analytics organizes this data into the AuditLogs and AzureActivity tables, respectively.

Microsoft provides examples of Log Analytics queries, such as hunting for Azure Role assignments to newly added guest user accounts, demonstrating the practical application of log analysis in identifying potential security threats and vulnerabilities.

Understanding the scope and complexity of threat actor actions is crucial in fortifying defenses against cyberattacks.

The detailed analysis of logs enables organizations to trace attackers’ steps, from the initial breach to their movements within the Azure environment.

This insight is invaluable in developing strategies to prevent future attacks and enhance the security posture of cloud subscriptions.

Scope and Complexity

The investigation of cloud environments in Azure subscriptions reveals the multi-faceted nature of maintaining a secure and resilient cloud environment.

Microsoft’s guidance on utilizing logs effectively, and ideally centralizing them, empowers organizations to enhance their threat hunting capabilities.

This proactive approach is essential in identifying potential security threats before they can cause significant damage.

The utilization of Azure Logs for identifying threats is a testament to Microsoft’s commitment to providing advanced tools and methodologies for cybersecurity.

By leveraging these insights and techniques, organizations can significantly improve their ability to detect and respond to cyber threats, ensuring the security and resilience of their cloud environments.

94% of organizations experience security problems in production APIs, and one in five suffers a data breach. As a result, cyber-attacks on APIs increased from 35% in 2022 to 46% in 2023, and this trend continues to rise.
Key takeaways include:

  • An exploit of OWASP API Top 10 vulnerability
  • A brute force ATO (Account Takeover) attack on API
  • A DDoS attack on an API
  • Positive security model automation to prevent API attacks
