Episode 11 — Explain Model Lifecycle States: Training, Tuning, Serving, and Retirement Criteria

This episode explains the full model lifecycle in a way that maps directly to SecAI+ governance, risk, and operational control questions, because exam scenarios often hinge on where a model is in its lifecycle and what controls are appropriate at that moment. You will define the major states, including initial training, iterative tuning, validation and approval gates, production serving, monitoring and maintenance, and end-of-life retirement or replacement. We will connect each state to concrete security responsibilities such as dataset handling rules during training, change control and documentation during tuning, environment hardening and access control during serving, and decommissioning practices that prevent residual data or artifacts from lingering. You will also learn common lifecycle failure patterns like deploying an experimental model without defined rollback criteria, skipping drift monitoring, or treating “retraining” as a routine action without re-assessing privacy, authorization, and logging impacts. By the end, you should be able to select lifecycle-appropriate controls in exam scenarios and justify them in plain, defensible terms.
