Program Implementation Simulation
Simulating the end-to-end implementation of a comprehensive vulnerability management program, integrating real organizational challenges, CAB meetings, and cross-team collaboration.
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 and operationalized.
Program Phases
1. Policy Draft Creation
Drafted a Vulnerability Management Policy as a starting point for stakeholder engagement, outlining scope, responsibilities, and remediation timelines.
2. Stakeholder Engagement (Mock Meeting)
Meeting with the server team to assess their capacity to meet proposed remediation timelines. Adjustments were made to ease them into the new process.
I had a chance to read through the policy draft... However, with our current staffing, we can’t meet the aggressive remediation timelines—especially the 48-hour window for critical vulnerabilities.
I totally understand. It is a bit aggressive. Perhaps we can extend the critical remediation period to one week for now.
That sounds reasonable. Can we also have some leeway in the beginning as we get used to the remediation and patching process?
Absolutely. We’re planning to give all departments about six months to adjust to the new process.
Initial Scanning & Permissions
Collaborated with the server team to initiate scheduled credential scans. A compromise was reached to scan a single server first, monitoring resource impact, and using "just-in-time" Active Directory credentials for secure, controlled access.
- Provisioned insecure Windows Server to simulate environment
- Negotiated Just-In-Time AD administrative scan accounts
- Assessed vulnerabilities (Wireshark, Ciphers, Guest Auth)
Active Remediation Cycles
Round 1
Outdated Wireshark Removal
Server team utilized targeted PowerShell scripts pushed to hosts to remotely remove vulnerable third-party installations. Confirmed via follow-up scan.
Round 2
Insecure Protocols & Ciphers
Deprecated cipher suites (TLS 1.0/1.1) disabled via PowerShell registry modifications post-CAB approval.
Round 3
Guest Account Local Admin
Identified and stripped local 'Guest' account from local Administrators group, hardening unauthorized lateral potential.
Round 4
Windows OS Updates
Windows update services re-enabled and synchronized with organizational patch management baseline.
