April 2026 Patch Tuesday discloses CVE-2026-20820 — a heap-based buffer overflow in Windows CLFS driver enabling local privilege escalation to SYSTEM. CVSS 7.8. Patch immediately: CLFS has a documented history as a ransomware kill chain component.
Skip the vendor demos. Here’s what Microsoft Copilot for Security actually does in day-to-day SOC operations—with specific prompts that produce reliable output, time metrics from real workflows, the failure modes nobody talks about, and an honest verdict by alert category.
Many SOC teams struggle with alert overload and high false positives, not due to insufficient tools like Microsoft Sentinel, but because of poor detection strategies. Effective detection engineering focuses on enabling suitable rules for specific environments and emphasizes understanding log data, deploying detections strategically, and regularly reviewing their effectiveness to improve overall trust in alerts.
This guide presents a framework to optimize Microsoft Sentinel costs while maintaining security. Key cost drivers include unclassified log ingestion and inefficient KQL execution. By classifying logs, implementing Data Collection Rules, and separating retention tiers, organizations can minimize expenses and ensure compliance without compromising detection capabilities.
Microsoft Sentinel offers three storage options: Analytics Tier, Sentinel Data Lake, and Data Archive, each serving distinct purposes. Proper storage tiering is crucial to avoid high costs and inefficiencies. Understanding each tier’s intended use—detection, investigation, or compliance—is vital for effective security operations and maintaining a scalable system.
A comprehensive 2026 technical deep dive into Microsoft Sentinel’s evolution as a unified security data platform, covering architecture, Sentinel Data Lake design, DCR-based ingestion, normalization with ASIM, Defender integration, SOAR automation, and cost engineering strategies with practical KQL examples.
Effortlessly streamline your Microsoft Sentinel integration with this comprehensive guide. Learn how to automate data collection rule (DCR) association and Azure Monitor Agent (AMA) installation for virtual machines (VMs) using a single PowerShell script. Introduction Integrating VMs with Microsoft Sentinel is essential for robust security monitoring. However, manually managing Azure Monitor Agent installation and Data…
🚨 Just published a new blog post on mastering KQL in Microsoft Sentinel! 🚨
In this post, I dive into a must-have query that provides detailed insights into your SOC operations, including total incidents, new, active, and closed incidents, as well as incident duration. Whether you’re looking to optimize your incident response or improve reporting, this query is a game-changer for every SOC team.
In this blog, we’ll address a common issue causing drops in log ingestion from Linux machines to Microsoft Sentinel: the /var/log directory filling up. Learn how to automate log maintenance with cron jobs to keep your logs flowing smoothly and ensure uninterrupted monitoring and analysis with Microsoft Sentinel.
