  • Understanding of DoD cybersecurity requirements, RMF/ATO, NIST SP 800-53, and DISA STIG/SRG standards.
  • Experience with SIEM, endpoint security, enterprise logging, security monitoring, and ticketing platforms.
  • Ability to meet DoD 8140 qualification requirements and obtain required CSSP and Computing Environment certifications within 90 days.
  • Experience securing DoD cloud environments including AWS GovCloud, IL4/IL5/IL6, Cloud One, or ECMA (preferred).
