Senior Baseline Security Engineer (CIS & STIGs)

• Build Baselines: Create security configuration baselines using CIS Benchmarks and DISA STIGs.
• Tailor Benchmarks: Modify CIS and STIG benchmarks to meet the client’s organizational requirements, working with each system’s team to negotiate and document deviations and justifications.
• Write from Scratch: Develop new baselines from vendor documentation for technologies without an existing benchmark.
• Map to Controls: Translate low-level baseline settings into high-level FISMA, NIST 800-53, and client-specific security requirements.
• Use Vulnerability Data: Apply NVD and CVE information to keep baselines current with emerging vulnerabilities.
• Verify with Tenable: Run compliance scans to assess systems against existing baselines, reconcile findings with system owners, and keep baseline and scan results in step.
• Learn New Platforms: Pick up whatever technology needs a baseline next — servers, network devices, cloud and SaaS services, mobile — and build competence quickly from vendor documentation.
• Work Independently: Own assigned baselines with a light touch from the federal lead, and communicate status, deviations, and risk clearly.
• Support IT Operations: Review and customize general security configuration baselines and support their rollout across the environment.

Who You Are

• Vulnerability-Aware: Comfortable with NVD and CVE data.
• Scripting-Comfortable: Working familiarity with Linux; you can write a quick bash, PowerShell, or Python check to verify a setting, and you are at home with JSON/YAML.
• Tenable-Capable: You have verified baselines with Tenable (Nessus / Security Center) or a comparable compliance scanner.
• Autonomous Communicator: Comfortable owning work with minimal supervision, and clear with system owners when a control needs to bend.
