Full Job Description

Description:

Job Title: ACAS Cybersecurity Analyst

Location: Oakton, VA

Department: Cyber Security Services

Reports To: Management

FLSA Status: Full Time/Non-exempt

Description:

Apavo delivers cybersecurity services to military, defense, and critical infrastructure organizations, and we're growing our Cyber Security Services team. We're built on quality, clear communication, and the belief that every team member's input matters — paired with a genuine commitment to work-life balance and professional growth. If you want cybersecurity work that has real mission impact, backed by a team that invests in your development, we'd love to talk.

Job Purpose:

In this role, the ACAS Cybersecurity Analyst plays a key part in supporting a high-priority federal research mission, driving vulnerability management, compliance validation, and Continuous Monitoring (ConMon) efforts across complex, multi-enclave Risk Management Framework (RMF) environments.

Duties & Responsibilities:

ACAS Cybersecurity Analyst responsibilities include, but are not limited to:

Advanced ACAS Administration: Deploy, configure, and manage Tenable Security Center (Tenable.sc) and Nessus scanners across connected and air-gapped enclaves (NIPR, SIPR, JWICS, SAP).

Vulnerability, R&D & Directive Scanning: Execute and analyze credentialed and non-credentialed vulnerability scans. Tailor scan zones, profiles, and asset lists to ensure 100% visibility while preventing disruptions to fragile, experimental research systems. Perform targeted scanning to determine and verify system compliance with DCDC Communications Tasking Orders (CTOs).

Troubleshooting & Maintenance: Diagnose and resolve complex scanner connectivity issues, WMI/SSH credentialed scan failures, and perform manual/offline plugin and feed synchronizations for isolated, highly classified networks.

Multi-Framework Compliance Validation: Validate findings against DISA STIGs, CIS benchmarks, and specific IC/SAP security baselines. Conduct compliance checks using tools such as SCC, STIG Viewer, and Evaluate-STIG.

Risk & Remediation Tracking: Develop and maintain POA&M documentation. Monitor IAVA/IAVM notices and IC-specific vulnerability alerts. Collaborate with operations and engineering personnel to provide risk-based remediation strategies, tracking mitigation within systems of record (e.g., eMASS, Xacta).

Continuous Monitoring & Upstream Reporting: Execute ConMon activities, integrating ACAS outputs with local SIEM tools (e.g., Splunk) to maintain ongoing authorization and coordinate with the external Cybersecurity Service Provider (CSSP). Support upstream enterprise cybersecurity posture reporting, ensuring accurate data synchronization with the Continuous Monitoring and Risk Scoring (CMRS) system.

DoD & IC RMF Support: Support RMF lifecycle activities across multiple regulatory frameworks—including DoD RMF (DoDI 8510.01), Intelligence Community Directive 503 (ICD 503), and the Joint SAP Implementation Guide (JSIG). Maintain artifacts and map technical scan findings to NIST SP 800-53 and CNSSI 1253 controls.

The ACAS Cybersecurity Analyst is expected to have additional duties as assigned in support of corporate cybersecurity services and mission requirements. Additional details are reviewed in accordance with company policies.

Other:

Requirements:

Qualifications:

Education/Experience: Bachelor’s degree in Cybersecurity, Information Technology, or related field (or equivalent experience) with 5–7+ years of experience in DoD/IC cybersecurity, heavily focused on vulnerability management and RMF.
Clearance: Active Top Secret clearance with SCI eligibility. (Willingness to undergo a Counterintelligence (CI) or Full-Scope Polygraph for SAP readiness is highly preferred).
DoD Directive: DoD 8570.01-M / 8140.03 compliant for IAT Level II (e.g., Security+ CE, CySA+) or Level III (e.g., CASP+, CISSP).
ACAS Certification: Current DISA ACAS Operator and/or Administrator training certificate is required.
Technical Proficiency: Deep, hands-on administrative experience with ACAS (Nessus / Tenable.sc) infrastructure, including offline updates, CMRS integration, air-gapped deployments, and credentialed scan troubleshooting.
OS/Environment: Computing Environment (CE) certification (e.g., Linux+, Windows Server) or equivalent command-line experience is highly preferred for ACAS host management.
Framework Knowledge: Strong understanding of DoD RMF (DoDI 8510.01), IC RMF (ICD 503), JSIG, CNSSI 1253, NIST SP 800-53 controls, STIG implementation, and IAVA/IAVM/CTO remediation processes.
Tooling: Experience with SCC, STIG Viewer, eMASS, Xacta (heavily used in IC/SAP environments), and log aggregation tools (e.g., Splunk).
Communication: Strong analytical and problem-solving skills, with the ability to communicate technical cyber risks to non-technical program managers and research scientists.
