Who should own the response when simulation reveals risky employee behaviour?

Why This Matters for Security Teams

When simulation reveals risky employee behaviour, the issue is rarely just “awareness.” It can expose weak approval paths, overbroad access, credential sharing, poor separation of duties, or a business process that normalises risky shortcuts. The right owner must therefore be able to trigger both behavioural follow-up and control remediation. Under the NIST Cybersecurity Framework 2.0, this is a governance and risk management question as much as a training question.

Security teams often get this wrong by treating every simulation failure as a learning issue only. That works for low-risk phishing clicks, but not when the user can approve payments, reset credentials, approve access, or move data into sensitive systems. In those cases, the response needs an owner who can evaluate whether the behaviour is a one-off mistake, a control gap, or a sign that the role itself is too powerful. In practice, many security teams encounter the real risk only after a simulated failure lines up with a later abuse event, rather than through intentional escalation paths.

How It Works in Practice

The most effective operating model assigns primary coordination to security awareness or security operations, with IAM and the relevant business leader as co-owners for remediation. Security awareness manages the human response, IAM checks whether access, authentication, or privilege contributed to the exposure, and the business line confirms whether the workflow, incentive structure, or role design is part of the problem. This division of labour avoids the common failure mode where training is used as a substitute for access control.

For high-privilege or regulated roles, the response should include an identity review. That means validating group membership, administrative rights, emergency access, shared accounts, privileged session use, and recent changes to entitlements. Where simulation indicates a user handled secrets, approved an unsafe request, or ignored a policy boundary, the response may also require conditional access changes, just-in-time access, additional approval, or removal of standing privilege. The control intent aligns closely with NIST SP 800-53 Rev 5 Security and Privacy Controls, especially access control, awareness, and accountability practices.

• Security awareness owns the coaching plan, follow-up messaging, and simulation-based retraining.
• IAM owns privilege validation, entitlement review, and remediation of excessive access.
• The business owner owns workflow fixes, role redesign, and operational enforcement.
• Security governance owns escalation thresholds and determines when repeat behaviour becomes a control issue.

Good practice is to define response tiers before simulations begin, so low-risk outcomes generate coaching and higher-risk outcomes trigger review, monitoring, or access change. Where the employee belongs to a critical function, the business line should also decide whether the behaviour creates fraud, resilience, or segregation-of-duties risk. These controls tend to break down when simulations are run in isolation from IAM and HR processes because the organisation detects risky behaviour but cannot change the access or workflow that made it possible.

Common Variations and Edge Cases

Tighter response pathways often increase operational overhead, requiring organisations to balance rapid coaching against the cost of access reviews and business disruption. That tradeoff is necessary because not every failure means the same thing. A junior user who clicks a simulated lure may need awareness reinforcement, while a privileged user who approves an unsafe action may need an identity and process review. There is no universal standard for this yet, so current guidance suggests using role sensitivity and potential impact as the deciding factors.

Edge cases usually appear in high-trust environments, outsourced operations, shared service teams, and roles with emergency access. In those settings, the line between “employee behaviour” and “control design” becomes thin. A simulation might surface a risky response that is actually encouraged by poor system design, vague policy, or pressure to meet business deadlines. In agent-assisted or AI-enabled workflows, the same logic applies if a user relied on an assistant to process a request without checking context or authority. NHIMG treats this as an identity and governance signal, not just a training event.

If the organisation handles sensitive payments, regulated customer data, or privileged administration, the response may also need audit logging, manager review, and temporary restriction while the case is assessed. The key is to avoid one-size-fits-all coaching and instead match the response to the role, the permission set, and the downstream risk.
