Change is inevitable in IT environments, but without structure, even small adjustments can introduce security gaps or operational disruptions. This episode introduces change management as a formalized process for planning, approving, documenting, and verifying changes to systems, configurations, and policies. We discuss why change management is essential to cybersecurity—it ensures that changes are evaluated for risk, properly tested before deployment, and clearly communicated to stakeholders. From deploying software updates to decommissioning legacy equipment, change management supports accountability, rollback capabilities, and traceability. It also protects against insider threats and human error, both of which are among the leading causes of system downtime and security incidents. Effective change management balances the need for agility with the discipline of process control—enabling secure, stable innovation.
