Phishing Simulation
Pronunciation: FISH-ing sim-yuh-LAY-shun
Also known as: Simulated phishing exercise, Phishing test campaign
Definition
A phishing simulation is an authorized exercise that sends realistic but controlled phishing messages or scenarios to measure and improve how people recognize, report, and resist social engineering. It should be a learning and control-validation activity rather than a punitive test, and click rate alone is not a complete measure of organizational resilience. Operationally, teams should define objectives and authorization, protect participant privacy, avoid harmful themes, and provide immediate education.
Overview
A phishing simulation is an authorized exercise that sends realistic but controlled phishing messages or scenarios to measure and improve how people recognize, report, and resist social engineering.
Phishing Simulation is closely connected to Security Awareness Training, MFA Fatigue Attack, and QR Code Phishing (Quishing). It should be a learning and control-validation activity rather than a punitive test, and click rate alone is not a complete measure of organizational resilience.
Operational implementation should define objectives and authorization, protect participant privacy, avoid harmful themes, provide immediate education, measure reporting, test escalation paths, analyze role-specific risk, and improve technical controls based on findings.
The principal failure modes include loss of trust, public embarrassment, collection of unnecessary data, unrealistic scenarios, gaming the metric, repeated targeting of the same staff, and ignoring failures in email or identity controls.
Useful measures include reporting rate, credential-submission rate, time to report, repeat susceptibility, technical-control detection, and remediation completion.
Operationally, teams should define objectives and authorization, protect participant privacy, avoid harmful themes, and provide immediate education. Key risks include loss of trust, public embarrassment, collection of unnecessary data, and unrealistic scenarios.
Operational review of Phishing Simulation should reconstruct an authorized exercise that sends realistic but controlled phishing messages or scenarios to measure and improve how people recognize, report, and resist social engineering using the identities, communications, devices, and transaction records available for the affected case. Investigators should separate confirmed facts from hypotheses about report, and and resist social engineering, preserve the original evidence, and document why the event was cleared, escalated, or treated as a loss. Containment, recovery, and customer communication for the Phishing Simulation context should match the harm indicated by report, and and resist social engineering.
Key Takeaway
A phishing simulation is an authorized exercise that sends realistic but controlled phishing messages or scenarios to measure and improve how people recognize, report, and resist social engineering.
