Human element

Expanded Definition

The human element describes the portion of an incident that depends on people making unsafe choices, overlooking a warning, or being manipulated into taking an action that creates access. In NHI security, it matters because humans still approve access, handle credentials, and override controls, even when the target asset is a service account, API key, or automation workflow.

Definitions vary across vendors because some use the term broadly for all user error, while others narrow it to social engineering and behavioural exploitation. For NHI governance, the useful interpretation is operational: where human judgment, fatigue, urgency, or authority gradient can bypass a technical safeguard. That makes the concept closely related to NIST Cybersecurity Framework 2.0, which treats governance, awareness, and access control as shared responsibilities rather than one-time checks.

The human element is distinct from pure misconfiguration or software vulnerability because the failure path depends on a person doing the wrong thing at the wrong time. The most common misapplication is treating it as a training problem alone, which occurs when organisations ignore workflow pressure, approval design, and exception handling.

Examples and Use Cases

Implementing controls for the human element rigorously often introduces friction, requiring organisations to weigh faster approvals against stronger verification and accountability.

• An engineer pastes an API key into a chat tool while troubleshooting, and the credential is later harvested from logs or message history.
• A manager approves a privileged access request because the request appears urgent, even though the service account should have been governed by Ultimate Guide to NHIs-style lifecycle controls and just-in-time access.
• A developer reuses a token across environments because it is easier than requesting a separate secret, creating hidden blast radius across production and non-production systems.
• A help desk agent resets access after a convincing impersonation call, bypassing policy because the request is framed as a business emergency.
• An automation owner leaves a credential embedded in code during a hurried deployment, and the exposure persists until a repository scan or incident review finds it.

These scenarios align with broader guidance from NIST Cybersecurity Framework 2.0, which emphasizes protective controls that anticipate real human behaviour rather than idealised process compliance.

Why It Matters in NHI Security

The human element is central to NHI security because non-human identities are often created, approved, rotated, shared, and retired by people who are balancing speed, uptime, and convenience. That is where security breaks down: not necessarily at the cryptographic layer, but at the point where a human accepts a risky exception or mishandles a secret. NHIMG research shows that 80% of identity breaches involved compromised non-human identities such as service accounts and API keys, and 79% of organisations have experienced secrets leaks, with 77% of those incidents causing tangible damage, as reported in the Ultimate Guide to NHIs.

That is why human behaviour must be treated as part of the control surface for secrets management, privileged access, and incident response. If a process depends on perfect memory, perfect vigilance, or perfect approval hygiene, it will eventually fail under pressure. Governance should therefore assume that users will click, copy, approve, and reuse unless controls make the safe action the easiest action.

Organisations typically encounter the consequence only after a phishing message, rushed change, or access abuse has already exposed an NHI, at which point the human element becomes operationally unavoidable to address.
