The analyst will play a key role in identifying, validating, and mitigating vulnerabilities across Azure-based infrastructure and containerized workloads while ensuring alignment with DoD Risk Management Framework (RMF) controls defined in NIST SP 800-53 Rev. 5 and the CMMC 2.0 requirements derived from NIST SP 800-171. This role will leverage enterprise-grade security tools, including ACAS, Tenable Nessus, Microsoft Defender for Cloud, and Microsoft Sentinel, to perform vulnerability scanning, log correlation, threat hunting, and compliance reporting. The analyst will also contribute to secure DevSecOps pipelines by integrating automated security checks, ensuring misconfigurations are addressed early, and maintaining hardened baselines consistent with DoD and industry cybersecurity best practices.

In addition, the Cloud Vulnerability Analyst will help shape and enforce proactive cloud security strategies by analyzing threat intelligence, validating remediation actions, and collaborating with engineering teams to eliminate systemic risks. The role requires strong knowledge of Azure security architecture, cloud access control models, vulnerability lifecycle management, and the technical controls necessary for FedRAMP-high-equivalent and DoD cloud deployments. The analyst will be responsible for developing documentation, dashboards, and continuous improvement recommendations that enhance situational awareness and strengthen security posture. Ultimately, the position ensures that ARS’s cloud environment remains resilient, compliant, and aligned with the evolving landscape of DoD cybersecurity expectations and modern cloud security best practices.

Responsibilities include:

• Conduct recurring vulnerability scans using ACAS, Tenable Nessus, Microsoft Defender for Cloud, and other automated tools to identify security gaps across Azure cloud environments.
• Analyze and correlate alerts and logs within Microsoft Sentinel to detect threats, suspicious activity, and compliance deviations.
• Perform vulnerability triage, validation, and prioritization, ensuring remediation aligns with DoD RMF (NIST SP 800-53 r5) and CMMC 2.0 (NIST SP 800-171) requirements.
• Develop, maintain, and harden secure baseline configurations for Azure services, virtual machines, containers, and DevSecOps tooling.
• Implement and monitor CI/CD-integrated security controls to ensure early detection of misconfigurations and code-level vulnerabilities.
• Collaborate with cloud engineers, developers, and ISSO/ISSM personnel to recommend remediation actions and validate corrective measures.
• Prepare detailed vulnerability reports, dashboards, Plan of Action & Milestones (POA&M) updates, and compliance artifacts for audits and assessments.
• Support continuous monitoring strategies and security automation initiatives to enhance overall cloud security posture.
• Conduct threat hunting and security analysis using threat intelligence sources to identify emerging risks relevant to Azure cloud and DoD systems.
• Promote cybersecurity best practices by providing guidance, training, and technical recommendations to stakeholders across DevSecOps teams.
• Other duties as assigned

Qualifications/ Technical Experience Requirements:

• Must be a US citizen
• Bachelor’s degree in Cybersecurity, Information Technology, Computer Science, or a related technical field (or equivalent practical experience).
• Hands-on experience with vulnerability scanning tools such as ACAS, Tenable Nessus, Microsoft Defender for Cloud, or similar enterprise solutions.
• Working knowledge of Microsoft Azure, including security architecture, identity management, and cloud configuration best practices.
• Familiarity with DoD RMF (NIST SP 800-53 r5) and CMMC 2.0 / NIST SP 800-171 security control requirements.
• Experience analyzing security events using SIEM platforms such as Microsoft Sentinel.
• Strong understanding of vulnerability management principles, secure configuration baselines, and cybersecurity best practices.
• Ability to create clear documentation, communicate findings, and collaborate effectively with DevSecOps, engineering, and compliance teams.
