Building Patch Tuesday Response Process
Overview
Microsoft releases security updates on the second Tuesday of each month ("Patch Tuesday"), addressing vulnerabilities across Windows, Office, Exchange, SQL Server, Azure services, and other products. In 2025, Microsoft patched over 1,129 vulnerabilities across the year -- an 11.9% increase from 2024 -- making a structured response process critical. The leading risk types include elevation of privilege (49%), remote code execution (34%), and information disclosure (7%). This skill covers building a repeatable Patch Tuesday response workflow from initial advisory review through testing, deployment, and validation.
When to Use
- When deploying or configuring building patch tuesday response process capabilities in your environment
- When establishing security controls aligned to compliance requirements
- When building or improving security architecture for this domain
- When conducting security assessments that require this implementation
Prerequisites
- Access to Microsoft Security Response Center (MSRC) update guide
- Vulnerability management platform (Qualys VMDR, Rapid7, Tenable)
- Patch deployment infrastructure (WSUS, SCCM/MECM, Intune, or third-party)
- Test environment mirroring production configurations
- Change management process (ITIL-based or equivalent)
- Communication channels for cross-team coordination
Core Concepts
Patch Tuesday Timeline
| Day | Activity | Owner |
|---|

| T+0 (Tuesday afternoon) | Security team reviews advisories and triages | Security Ops |
| T+1 (Wednesday) | Qualys/vendor scan signatures updated | VM Platform |
| T+1-T+2 | Emergency patches deployed for zero-days | IT Operations |
| T+2-T+5 | Test patches in staging environment | QA/IT Ops |
| T+5-T+7 | Deploy to Pilot group (5-10% of fleet) | IT Operations |
| T+7-T+14 | Deploy to Production Ring 1 (servers) | IT Operations |
| T+14-T+21 | Deploy to Production Ring 2 (workstations) | IT Operations |
