The Role

You will own enterprise vulnerability management for a DoD logistics enterprise. The work is hands-on engineering: keeping the Assured Compliance Assessment Solution healthy and accurate across every enclave, pushing coverage into cloud workloads, and turning scan output into findings that remediation teams can act on. You will work alongside the incident response team and the Information Assurance Managers, and your reporting will drive what gets fixed first.

Job Duties

• Administer and sustain the enterprise vulnerability management platform across all DLA enclaves, covering Tenable Security Center, Nessus Scanners, Nessus Network Monitors, and Nessus Agents.
• Deploy and manage agent-based scanning so transient, remote, and disconnected endpoints stay continuously assessed.
• Engineer automated asset discovery and synchronization through APIs and cloud native integrations, so new cloud workloads and virtual machines enter scope without manual effort.
• Extend scanning coverage into authorized cloud environments including Microsoft Azure, Amazon Web Services, Oracle Cloud Infrastructure and Google Cloud Platform.
• Tune scan policies, credentialed scanning and scan windows to raise coverage and accuracy while protecting production performance.
• Execute credentialed vulnerability and DISA Security Technical Implementation Guide compliance scans across assigned IP ranges, subnets, cloud environments and platforms on DoD and DLA policy timelines.
• Manage, audit, and securely cycle scanning credentials and service accounts well enough to hold the mandated 98 percent authenticated scan success rate.
• Troubleshoot scan authentication failures, firewall blocking, and sensor routing anomalies that prevent a successful credentialed assessment.
• Produce the recurring vulnerability reporting that drives remediation decisions, and support exception and mitigation tracking.
• Make recommendations in line with the roles of CERT Incident Handlers and site Information Assurance Managers.

Clearance

Active DoD Secret. The position is designated IT II Non-Critical Sensitive, which requires a Tier 3 investigation adjudicated and current at the time of proposal submission. Top Secret is not required.
