Identity is the new perimeter. A robust ESA prioritizes identity governance to ensure that only authorized users, devices, and workloads can access corporate resources.
SABSA uses a layered approach to ensure that high-level business goals are traceably linked to specific technical configurations. Destination Certification Perspective Contextual
Existing technical debt can make it difficult to enforce a clean, top-down architecture. Address this by adopting a phased migration approach, wrapping legacy systems in modern security perimeters until they can be decommissioned.
The final layer focuses on day-to-day management, monitoring, and maintenance. It defines the operational workflows, patch management schedules, incident response playbooks, and continuous compliance auditing processes. Core Components of a Modern ESA Identity is the new perimeter
: The vertical layer ensuring operational continuity across all others.
By cascading down from the (the business view) to the Component Layer (the technical view), SABSA ensures that no technical tool is deployed without a clear business justification. Step-by-Step Implementation of a Business-Driven ESA
