Vulnerability Management Program Standup

Engagement Overview

Cybernerds was engaged to establish a vulnerability management program for a nonprofit organization that had no prior vulnerability scanning, patching governance, or remediation tracking. The engagement began with IRIS to assess the current exposure, followed by PDS to deploy Defender Vulnerability Management and build sustainable remediation workflows appropriate for the organization's size and IT capacity.

Initial State

The organization had basic IT operations but no structured approach to vulnerability management. Key findings during IRIS included:

• ✓No vulnerability scanning tool deployed — the organization had no visibility into software vulnerabilities across its endpoints
• ✓Patching was ad hoc — Windows Updates applied only when users manually accepted prompts
• ✓Third-party applications (browsers, PDF readers, conferencing tools) were never patched centrally
• ✓No remediation tracking or SLA framework for addressing discovered vulnerabilities
• ✓IT support provided by a single part-time administrator with no security specialization
• ✓Organization handling donor PII and financial data with no demonstrable security controls

Key Challenges

• ✓Visibility: Zero baseline — no understanding of current vulnerability exposure
• ✓Resources: Single part-time IT administrator with limited security expertise
• ✓Patching: No centralized patch management for OS or third-party applications
• ✓Process: No remediation workflow, prioritization framework, or tracking mechanism
• ✓Compliance: Donor data handling required demonstrable security controls for grant applications
• ✓Sustainability: Any solution needed to be maintainable by a small team with minimal overhead

Solution Design — PDS Framework

• ✓Vulnerability Scanning: Defender Vulnerability Management deployed via Intune to all endpoints
• ✓Patch Management: Windows Update for Business rings configured for staged OS patching
• ✓Third-Party Patching: Intune application update policies for browsers, runtimes, and productivity tools
• ✓Remediation Workflow: Prioritization by CVSS severity — Critical (7 days), High (14 days), Medium (30 days)
• ✓Reporting: Monthly vulnerability summary with trend tracking for board and grant reporting
• ✓Knowledge Transfer: Documented runbook for the IT administrator to execute monthly vulnerability review

Implementation — PDS Execution

Initial remediation was executed as part of the engagement. Ongoing maintenance was designed to require less than 4 hours per month from the IT administrator.

• ✓Deployed Defender Vulnerability Management across all enrolled endpoints via Intune
• ✓Ran initial vulnerability scan — identified 47 critical and 112 high-severity vulnerabilities across the fleet
• ✓Remediated all critical vulnerabilities in the first sprint (primarily unpatched OS and browser versions)
• ✓Configured Windows Update for Business with three deployment rings (pilot, standard, broad)
• ✓Created Intune Win32 app packages for third-party application updates
• ✓Built monthly vulnerability review checklist and remediation tracking spreadsheet
• ✓Configured Security Center alerts for new critical vulnerabilities
• ✓Trained IT administrator on vulnerability review, remediation prioritization, and reporting

Validation — PDS Validation Phase

• ✓All endpoints reporting to Defender Vulnerability Management console
• ✓Critical vulnerability count reduced from 47 to 0 within the first two weeks
• ✓High-severity vulnerabilities reduced by 89% within 30 days
• ✓Windows Update for Business rings deploying patches on schedule without user disruption
• ✓Third-party applications updated to current versions across all devices
• ✓IT administrator completed first independent monthly vulnerability review using the runbook
• ✓Monthly report generated and delivered to executive director for board review

Outcome

• ✓Vulnerability management program operational from zero baseline
• ✓All critical and high-severity vulnerabilities remediated within SLA
• ✓Automated OS and third-party patching reducing manual intervention
• ✓Monthly vulnerability reporting supporting grant compliance documentation
• ✓Sustainable process requiring less than 4 hours/month to maintain
• ✓IT administrator enabled to independently manage the program
• ✓Foundation for future security maturity improvements
