 * Define and lead the NCS security architecture, trust boundaries, and system-wide controls.
 * Architect encryption, identity/MFA, and RBAC for tactical and DIL environments.
 * Design secure cloud integration and zero-trust remote access for tactical data pipelines.
 * Lead RMF/ATO strategy, author key artifacts, and coordinate with ISSM/ISSO/AO stakeholders.
 * Conduct architecture-level threat modeling and risk assessments; define design-level mitigations.
