Microsoft Sentinel Analytical Rule Tuning

Microsoft Sentinel's analytical rules form the backbone of your security operations centre's detection capabilities. However, deploying rules isn't enough. Effective rule tuning is essential for maintaining high detection accuracy whilst minimising alert fatigue. This comprehensive guide explores the critical aspects of Sentinel rule tuning that every security team should master.

Why Rule Tuning Matters

Out-of-the-box detection rules often generate excessive false positives or miss subtle attack patterns specific to your environment. Without proper tuning, security teams face alert fatigue, increased mean time to detection (MTTD), and reduced confidence in their security monitoring capabilities. Effective rule tuning transforms generic detections into precise, actionable intelligence tailored to your organisation's unique threat landscape.
