Employees whose roles, privileges, or access make them more likely to be targeted or more damaging if compromised. Common examples include finance staff, executives, and other users with access to sensitive information or approval authority. These groups often need closer monitoring and tailored training.
What High Risk Individuals Means in Security Practice
High risk individuals are not defined by job title alone. The category is about exposure: who can approve payments, see sensitive data, change systems, or make decisions that attackers can exploit for fraud, coercion, or insider misuse.
That makes the term useful for security teams because it ties people risk to business impact. A well-chosen definition helps distinguish ordinary user groups from those whose compromise would create outsized operational, financial, or confidentiality damage.
Why the Category Matters for Control Design
The practical value of the label is that it helps security teams decide where to concentrate monitoring, awareness, and access scrutiny. It is a prioritisation concept, not a separate identity class, and it should map to the actual privileges, data access, and approval authority a person has.
In many environments, the most important question is not whether someone is “senior”, but whether they can authorise money movement, release sensitive records, reset access, or influence downstream workflows. Those functions create a larger blast radius if an account is phished, coerced, or misused.
This is why NIST Privacy Framework can be useful where the group’s access includes sensitive personal or customer data, and why NIST Cybersecurity Framework 2.0 remains a practical way to organise governance, protection, detection, response, and recovery around those higher-impact users.
How Organisations Commonly Identify High Risk Individuals
The most defensible approach is function-based. Finance, executives, procurement, legal, administrators, and users with approval or exception authority are common examples, but the real test is the combination of access scope, data sensitivity, and business influence.
Groups often become high risk because they sit at decision points, not because they occupy a prestige role. A mid-level user with payment approval rights or access to sensitive customer records may be higher risk than a more visible employee with limited permissions.
That is also why identity and access controls matter here. NIST SP 800-53 Rev 5 Security and Privacy Controls is relevant because it anchors access control, auditing, and configuration discipline around the kind of privileged access these users often have.
Monitoring, Training, and Governance Considerations
High risk individuals usually warrant closer monitoring because their accounts are more attractive targets and their actions are more consequential. That can include stronger alerting for anomalous logins, unusual approvals, unusual data access, and changes to contact or recovery details.
They also benefit from tailored training that reflects the threats they are most likely to face, such as spear phishing, executive impersonation, business email compromise, and fraudulent approval requests. Generic security awareness is rarely enough when the attacker is trying to exploit trust, urgency, or delegated authority.
For organisations that want a broader control view, FIRST EPSS is a useful reminder that prioritisation should focus on likelihood and impact, while SOC 2 Trust Services Criteria (AICPA) is often the governance lens used when those users touch sensitive systems or regulated information.
Risk and Threat Considerations
High risk individuals are attractive targets because compromise can unlock approval authority, confidential information, or the ability to bypass normal checks. The main exposure is not just account takeover, but downstream abuse of trust, including fraudulent payments, sensitive-data theft, and unauthorised changes made through legitimate channels.
Failure mechanism: Attackers often exploit human trust, weak verification, or overbroad permissions to turn a single compromised account into a high-impact event. If the organisation cannot distinguish expected from unusual behaviour for these users, malicious activity can blend into normal business workflow.
Impact: A successful compromise can create outsized financial loss, regulatory exposure, reputational damage, and operational disruption. In the worst case, one account becomes a bridge to broader fraud or data compromise because the user’s authority is already accepted by the business.
Standards & Framework Alignment
This section maps relevant standards and security frameworks to the operational risks and controls described in this guidance.
NIST CSF 2.0, NIST SP 800-63 and CIS Controls v8 set the governance and control requirements practitioners need to meet.
| Framework | Control / Reference | Relevance |
|---|---|---|
| NIST CSF 2.0 | GV.PO — Policy | Defines governance and policy for prioritising higher-risk user groups. |
| PR.AA — Identity Management, Authentication, and Access Control | Covers access control for users whose privileges increase exposure. | |
| DE.AE — Anomalies and Events | Supports detection of unusual activity on high-risk accounts. | |
| Recommendation — Define policy for monitoring and protecting higher-risk users. Apply stronger access controls to users with elevated impact. Detect anomalous behaviour on higher-risk accounts early. | ||
| NIST SP 800-63 | IAL/AAL — Identity Assurance and Authenticator Assurance | Supports stronger authentication where user compromise would be more damaging. |
| Recommendation — Use stronger authenticators for users with sensitive access. | ||
| CIS Controls v8 | 5 — Account Management | Addresses account oversight and review for users with sensitive privileges. |
| 6 — Access Control Management | Limits access to the sensitive systems and approval paths these users often hold. | |
| Recommendation — Review and restrict accounts that carry elevated business impact. Enforce least privilege for users with approval or data access. | ||
