Azure Sentinel: What is it, What are the Four Key Security Fundamentals, and Why You Should Know About It

Microsoft’s cloud Security Incident Event Management (SIEM) solution leverages modern day enhancements such as Security Orchestration Automated Response (SOAR), Machine Learning (ML), and Artificial Intelligence (AI). The result? Analytics that displace the traditional SIEM complexity and cost to obtain a “bird’s-eye” view of the complete IT environment.

Microsoft’s Azure Sentinel has been built on top of the following four principal security fundamentals:

  1. Collect - Easily gathers data at cloud scale across users, devices, applications and infrastructure both on-premises, and across multiple clouds.
  2. Detect - Sentinel recognises previously discovered threats and minimises false positives by leveraging analytics and threat intelligence drawn directly from Microsoft.
  3. Investigate - Artificial intelligence helps to identify threats and hunt suspicious activities at scale.
  4. Respond – Built-in automation processes and response capabilities enable a calm and quick incident response.

The three primary benefits enterprises are recognizing include the following:

  • Built-In AI/ML – This enhancement reduces the data noise, mitigates skills gap (to some degree), and reduces burden of time and resources on enterprises.
