Position Summary
The ISSM owns the security posture of JANUS corporate and CUI systems. You keep us compliant with RMF, NIST SP 800-53, NIST SP 800-171, and CMMC Level 2. You also bring hands-on technical depth across Microsoft 365, AWS, Windows, Linux, and Active Directory.
This is a hybrid role that combines cybersecurity compliance oversight with system security and user training coordination.
The Cybersecurity Compliance Administrator will work closely with DCSA, the Facility Security Officer (FSO), external MSP, MSSP, service providers, and organizational leadership to ensure corporate systems remain secure and compliant.
Key Responsibilities
- Maintain and update cybersecurity documentation, including SSPs, POA&Ms, policies, procedures, and user access records.
- Implement and monitor security controls for NIST SP 800-171, NIST SP 800-53, and CMMC Level 2. Run continuous monitoring, collect evidence, and report risk to leadership.
- Monitor and analyze Microsoft 365, including GCC High: Exchange Online, Teams, SharePoint, and Entra ID. Review Conditional Access, MFA, privileged roles, and Defender, Purview, and Intune findings.
- Lead preparation for CMMC assessments, DCSA reviews, and audits. Work with DCSA, the FSO, service providers, and leadership.
- Contribute to security audits, assessments, and continuous monitoring processes.
- Coordinate and deliver end-user cybersecurity and IT training (e.g., phishing awareness, acceptable use).
- Support onboarding/offboarding and system access management.
- Assist with patch management, system hardening, and endpoint configurations.
- Own the secure development program. Run SAST, DAST, and dependency scanning tools (such as Snyk, SonarQube, OWASP ZAP, or Burp Suite) in CI/CD pipelines, and triage findings with developers.
- Assess AWS security (commercial and GovCloud): IAM, Security Hub, GuardDuty, CloudTrail, and AWS Config. Confirm that cloud services meet FedRAMP Moderate (or equivalent) before they hold CUI.
- Assess Windows and Active Directory security: STIG and CIS baselines, Group Policy, privileged groups, tiered administration, service accounts, LAPS, BitLocker, and application control. Monitor for identity attacks.
