Vulnerability Management Program
A comprehensive vulnerability management program implementation simulating real-world enterprise security operations, from policy creation to full remediation cycles.
Project Overview
Inception State
The organization has no existing policy or vulnerability management practices in place. No formal scanning, assessment, or remediation processes exist.
Completion State
A formal policy is enacted, stakeholder buy-in is secured, and a full cycle of organization-wide vulnerability remediation is successfully completed.
Program Phases
Phase 1: Policy Development
- Drafted comprehensive Vulnerability Management Policy
- Defined scope, responsibilities, and remediation timelines
- Adjusted timelines based on stakeholder feedback (48h to 1 week for critical)
Phase 2: Stakeholder Engagement
- Conducted mock meetings with server team for policy buy-in
- Negotiated scan permissions and credential management
- Implemented just-in-time AD credentials for secure scanning
Phase 3: Scanning & Assessment
- Provisioned insecure Windows Server to simulate environment
- Performed authenticated Tenable scans
- Prioritized vulnerabilities by ease of remediation and impact
Phase 4: Remediation Cycles
- Round 1: Outdated Wireshark removal via PowerShell
- Round 2: Insecure protocols & cipher suites remediation
- Round 3: Guest account group membership fix
- Round 4: Windows OS updates applied
Results
Total Vulnerability Reduction
Critical Vulnerabilities Resolved
High Vulnerabilities Reduced
Medium Vulnerabilities Reduced
Ongoing Maintenance Mode
After completing the initial remediation cycle, the vulnerability management program transitions into Maintenance Mode. This phase ensures vulnerabilities continue to be managed proactively.
Scheduled Scans
Weekly/monthly scans to detect new vulnerabilities as systems evolve
Patch Management
Continuous security patches ensuring no critical vulnerabilities remain
Remediation Follow-ups
Address newly identified vulnerabilities promptly based on risk
Policy Reviews
Periodic review to align with latest security best practices
Audit & Compliance
Internal audits ensuring compliance with policy and regulations
Stakeholder Communication
Maintain open coordination with remediation teams
