Identity and access management (IAM) serves as the control plane for trust for all digital identities. Effective IAM must continually verify, authenticate, and authorize identities, secure access to logical and physical resources, and manage privileges. Use Forrester’s IAM lifecycle to set strategic direction and apply rigor to IAM. By applying this lifecycle, security and risk (S&R) pros will optimize for hardened security, good user experience, and operational efficiency across all user populations — workforce, partners, customers, and machine identities — for both digital and physical access to corporate resources.
