💡 Security Tip of the Week

Prioritizing Critical Patches

With 107 Microsoft patches this month, here's how to prioritize:

Immediate Priority (Patch This Week):

1. Exchange Servers - Especially internet-facing systems

2. Domain Controllers - Critical for Kerberos vulnerability

3. Systems with "Critical" CVSS ratings - Remote code execution risks

Standard Priority (Patch This Month):

1. Important-rated vulnerabilities - Elevation of privilege risks

2. Client systems - Lower risk but still important

3. Non-internet-facing servers - After critical systems are patched

Pro tip: Test patches in a lab environment first, but don't delay critical security updates for extensive testing.

🎯 Quick Wins for Your Security Posture

For IT Teams:

• Review Microsoft's security advisory for your specific software versions

• Schedule emergency patching for Exchange servers and domain controllers

For Security Teams:

• Monitor for exploitation attempts against newly disclosed vulnerabilities

• Update threat hunting queries to detect post-exploitation activity

For Small Organizations:

• Enable automatic updates for non-critical systems

• Prioritize patching internet-facing systems first
