Security by Design

Statement​

Security and compliance controls are defined, designed, and validated at architecture time, not retrofitted after build.

Rationale​

Late-stage security remediation is 10-100x more expensive than designing it in. Supply chain systems process sensitive commercial, financial, and personal data requiring robust protection.

Implications​

  • Every architecture review includes a threat model
  • Zero-trust networking is the default posture
  • Security acceptance criteria are part of the definition of done
