Insider Risk Glossary: Key Terms for Insider Risk and Insider Threat Management
The Insider Risk Glossary defines the terms organizations use to understand, communicate, and manage insider risk and insider threat. Insider risk is cross-functional. It involves security, risk, legal, privacy, HR, compliance, data protection, identity, physical security, investigations, and business leadership. A shared vocabulary helps those functions make better decisions together.

PAM
Privileged Access Management (PAM) refers to controls and technologies used to govern, monitor, secure, and review privileged accounts and privileged sessions.
Privileged Insider
A privileged insider is an insider with elevated permissions that allow them to administer systems, access sensitive data, bypass ordinary controls, or affect business-critical operations.
Remote Worker Risk
Remote worker risk is the insider-risk exposure associated with work performed outside controlled enterprise locations, often involving remote access, home networks, unmanaged environments, or distributed collaboration.
Residual Risk
Residual risk is the insider-risk exposure that remains after controls, mitigations, decisions, or process changes have been applied.
Risk Appetite
Risk appetite is the amount and type of insider-risk exposure an organization is willing to accept in pursuit of its objectives.
Risk Tolerance
Risk tolerance is the acceptable variation around an organization defined risk appetite for a specific context, asset, process, or business decision.
Sabotage
