Define and publish approved security patterns and reference architectures (secure-by-design blueprints, guardrails, and standards) that engineering teams build against
Drive the Zero Trust network strategy, including macro- and micro-segmentation, software-defined perimeter, secure internet edge (SASE/SSE, ZTNA, secure web gateway, DNS security, DDoS protection), and secure remote access
Advance security automation and policy as code so infrastructure controls are codified, repeatable, and continuously validated
Coordinate remediation of infrastructure findings and non-compliant items to meet applicable compliance standards and best practices
Monitor changes in regulations and compliance standards (e.g., NIST 800-53) and proactively update standards, patterns, and architectures
Manage vendors and external partners that support infrastructure security tooling and services
