SABSA Implementation in E-Commerce: A Strategic Security Architecture Perspective

Introduction

The evolution of e-commerce has fundamentally transformed business operations, introducing complex security challenges that demand structured architectural approaches. This article examines how the SABSA framework addresses these challenges through a business-aligned security architecture, with particular focus on e-commerce implementations.

Current State of E-Commerce Security

Recent analysis from industry research reveals concerning trends in e-commerce security:

• Average breach cost: $4.3M (enterprise) / $108,000 (SME)
• Mean time to identify breaches: 197 days
• Regulatory non-compliance costs:
  • GDPR: Up to 4% annual revenue
  • PCI DSS: $5,000-$100,000 monthly
• Business impact:
  • System downtime: $5,600 per minute
  • Customer churn post-breach: 75%
  • Recovery timeframe: 6-12 months
