Understand what needs protection
Start with your critical systems, sensitive information, and the people who need access. Understand the business impact of a disruption before deciding which controls deserve priority.
Consider access early
Define roles and responsibilities while designing the system. Apply least-privilege thinking, use appropriate authentication controls, and make access review part of ongoing operations.
Design for response and recovery
Prevention is only one part of resilience. Include monitoring, incident ownership, backups, and recovery planning in your architecture. Review and test those plans as your environment changes.
General information only. Platform and security decisions should be assessed against your business requirements.
