Context: Without a customizable checklist for enterprise security guidance in architecture, organizations may struggle to consistently protect the confidentiality, integrity, and availability of their data and systems. This can lead to increased vulnerabilities, higher risk of data breaches, and potential compliance issues. Inconsistent security practices may also result in operational disruptions and loss of trust from stakeholders. Overall, the absence of such a checklist can significantly weaken the security posture of the Power Platform environment.

Solution: A Well-Architected workload must be built with a zero-trust approach to security. A secure workload is resilient to attacks and incorporates the interrelated security principles of confidentiality, integrity, and availability (also known as the CIA triad) in addition to meeting business goals. Any security incident has the potential to become a major breach that damages brand and reputation. To assess how well security strategy works for workload it is critcal to use Security Checklist adopted from Well-Architected Framework.

Impact: If these principles aren't applied properly, a negative impact on business operations and revenue can be expected. Some consequences might be obvious, like penalties for regulatory workloads. However, others may be less apparent and could result in ongoing security problems before they're detected. In many mission-critical workloads, security is the primary concern, alongside reliability, given that some attack vectors, like data exfiltration, don't affect reliability. Security and reliability can pull a workload in opposite directions because security-focused design can introduce points of failure and increase operational complexity. The effect of security on reliability is often indirect, introduced by way of operational constraints. This checklist helps enterprises carefully consider tradeoffs between security and reliability.
