At AW InfraSec, we have recently embarked on a journey with Azure Sentinel, Microsoft’s cloud-native Security Information and Event Management (SIEM) solution. Over the past few months, we have explored its capabilities and witnessed firsthand the transformative impact it can have on an organization’s security operations. In this blog post, we would like to share our experiences and insights, particularly for those who are facing challenges with security threats and are in search of an efficient SIEM solution.

The Challenges with Traditional SIEM Solutions

Managing security logs and addressing threats can be an overwhelming task. Traditional SIEM systems often require substantial on-premises infrastructure, constant maintenance, and can be inflexible when scaling up or down to meet changing demands. Our team experienced these challenges firsthand, dedicating significant time to managing the tools rather than focusing on the core objective of safeguarding our clients.

Exploring Azure Sentinel

In our search for a more efficient solution, we turned our attention to Azure Sentinel. Initially, we approached it with a degree of skepticism, questioning whether a cloud-native SIEM could truly meet our needs. However, upon implementation, we were pleasantly surprised by its performance and capabilities.

Key Advantages of Azure Sentinel

• Ease of Integration: Azure Sentinel seamlessly connected with our existing data sources, including Azure services, on-premises systems, and third-party applications.
• Scalability: Being built on Azure, it allowed us to scale resources up or down effortlessly, eliminating concerns over hardware limitations.
• Advanced Analytics: The built-in artificial intelligence and machine learning features enabled us to detect threats that might have otherwise gone unnoticed.

Enhancing Data Log Collection

Azure Sentinel’s approach to data log collection significantly improved our security operations.

Unified Data Collection

We were able to consolidate logs from a variety of sources:

• Azure Services: Integration with services such as Azure Active Directory and Azure Firewall was straightforward.
• On-Premises Systems: Using the Azure Sentinel agent, we collected logs from our physical servers.
• Third-Party Solutions: Built-in connectors facilitated the integration of logs from other vendors.

Interactive Dashboards

The customizable dashboards provided by Azure Sentinel allowed us to visualize data effectively, enabling quick identification of anomalies and detailed analysis when necessary.

Kusto Query Language (KQL)

While there was an initial learning curve with KQL, it proved to be an invaluable tool for performing complex queries and analyses on our log data, uncovering insights that enhanced our security posture.

Leveraging Microsoft 365 E5 Benefits

Many of our clients possess Microsoft 365 E5 licenses, and we recognized the significant advantages of utilizing these resources.

Inclusive Security Features

The E5 license includes a suite of advanced security tools that integrate seamlessly with Azure Sentinel:

• Microsoft Defender for Endpoint
• Azure Active Directory Premium P2
• Microsoft Cloud App Security

These integrations enhanced our overall security framework.

Cost Efficiency

By leveraging the features included in the E5 license, we were able to avoid additional costs associated with alternative solutions, resulting in financial benefits for both us and our clients.
