Data Hardening

Tagline: Immutability meets Encryption.

Strategic defense for the data fabric. Focus: Deterministic logic for Immutable Storage and end-to-end Encryption across the hybrid cloud.

Data Privacy

Level 100: Encryption Logic

  • At-Rest Security: AES-256 standards for storage volumes.
  • In-Flight Safety: Standardizing TLS 1.3 for all replication traffic.
  • KMS Integration: Managing keys via internal or external providers.

Architect’s Verdict: Encryption is the baseline for data sovereignty. If you don’t own the keys, you don’t own the data.

Integrity

Level 200: WORM Storage

  • Hardened Repos: Linux-based immutability with XFS.
  • Object Lock: API-level WORM for cloud storage.
  • Time-Locking: Setting deterministic retention periods for survival.

Architect’s Verdict: Hardening is a dual-layer process. Encryption keeps it private; immutability keeps it permanent.

Assurance

Level 300: Compliance Auditing

  • Identity-Based Access: MFA for all data hardening modifications.
  • Immutable Logs: Auditing the access logs of encrypted volumes.
  • Four-Eyes Logic: Multi-admin approval for retention policy changes.

Architect’s Verdict: In a Zero-Trust world, hardening is not just a configuration—it is a continuous state of verification.
