A breach starts with one wrong permission. One account with too much power. One missing check. That is where Identity Management Separation of Duties comes in.
Separation of Duties (SoD) is the principle of splitting critical tasks across different roles to prevent abuse, fraud, and accidental errors. In identity management, it means no single person or account can perform every step of a high-risk operation without oversight.
The core idea: a user with broad permissions is a vulnerability. Access provisioning must be segmented. Approval must involve another role. Privilege escalation should require a second, independent identity. By hard-coding these constraints into your IAM systems, you block entire attack paths.
Effective Identity Management Separation of Duties starts with a clear map of all identities, roles, and permissions. Identify toxic combinations—cases where one user can both approve and execute sensitive actions. Remove them. Enforce policy at the identity provider level. Align your directory groups, RBAC rules, and workflow engines so that no bypass is possible.
Audit trails are the proof. Every separated duty should leave a trace: who requested, who approved, who executed. Logs must be immutable and centralized. Tie them to alerts for any attempt to override or merge roles.
