Mission & Challenge

HHS required continuity of services for the Human Resources Management Enterprise Services Bus (HRMESB) on Azure while measurably improving cyber resilience. The mandate: reduce inherited POA&Ms, enable disaster recovery in a target region, and move to a secure, repeatable deployment pattern – minimizing tenant-wide permissions and modernizing legacy SFTP.

What We Did

Fix

  • Resolved legacy POA&Ms with evidenceable remediation steps.
  • Hardened baselines and IAM; standardized RBAC.
  • Centralized logging and alerting for faster issue triage.

Fortify

  • DR target-region and operational runbooks.
  • Terraform for consistent, environment-based deployments.
  • Replaced VM-based SFTP with Azure Blob SFTP and event-driven processing.

Future-Proof

  • Zero Trust roadmap aligned to HHS priorities.
  • User-Assigned Managed Identity (UAMI) per environment to enforce least privilege.
  • Defender for Cloud coverage and alerting.
