- Independently interpret the findings of vulnerability scanning utilities such as ACAS (Tenable Nessus) and SCAP (STIG benchmark) and manage a Plan of Actions and Milestones (POA&M) for remediation of findings.
What We Value
- Proficiency in interpreting and communicating government policy to a diverse audience.
- Ability to multitask under pressure, using time management and organizational skills.
- Specific experience working in both traditional on premises environments and cloud environments such as Amazon Web Services (AWS).
- Experience accrediting IT systems against U.S. Government standards including NIST SP 800-53, CNSSI 1253, and the DISA STIGs, using frameworks like DOD RMF, ICD 503, or DIACAP.
- Initiative in proactively identifying problems before they arise and creativity in proposing solutions.
What We Require
- Active U.S. DoD Top Secret clearance with SCI eligibility.
- Active DOD 8140 or 8570 Certification (e.g. CISSP or Security+).
- Active IAT II certification.
- Minimum 2 years experience directly supporting a customer's ATO/RMF process.
- Proven experience using the eMASS or XACTA accreditation management software systems.
- Be at customer site 5 days per week.
- Ability to travel domestically and internationally 25% of the time if needed
