Chapter 5 – How NOT to Govern Microsoft Sentinel Operations
Why “Just Turn It On” Becomes “Why Is Everything On Fire?” Think of Sentinel governance like: Sentinel will run without governance.It just won’t protect you. Why This Matters (Context) Most Sentinel failures don’t happen because of bad analytics or missing logs.They happen because operations were never governed. When governance is missing: Sentinel becomes expensive visibility,… Read More →
