The core vocabulary (memorize cold)
Term
One-line definition
Security awareness
Ongoing process to build the knowledge, attitudes, and behaviors a workforce needs to recognize and respond to threats
Security culture
The shared norms, beliefs, and unwritten rules that determine how people actually behave toward security daily
Human firewall
A trained, engaged, fast-reporting workforce that catches what automation misses — the human as a sensor grid
Phishing simulation
An authorized, governed exercise sending benign fake-phishing to your own staff to measure behavior and teach
Click rate
clicked / received — the susceptibility number
Report rate
reported / received — the detection number (often matters more)
Social engineering (defense)
Program, behavioral, and cultural counters to the manipulation of people (Ch. 2 owns the attack)
Just-in-time training
A small lesson delivered at the moment of a decision or right after a risky action (e.g., the teachable-moment page)
Nudge
A change to the choice environment that steers toward safety without forbidding options (e.g., external-sender banner)
Security champions
Volunteers embedded in business units (not security staff) who advocate, translate, and report locally
Insider threat
Harm caused by someone with authorized access — malicious (theft/sabotage) or accidental (honest error)
The central thesis
Behavior, not knowledge, is the goal. Knowing the rule and following it under stress are different cognitive events. The annual quiz measures knowledge and predicts almost nothing about behavior. Theme 3: the human is the weakest link and the strongest asset — the program moves people from the first to the second.
The funnel: received → opened → clicked → submitted (the real damage); reported is independent. Drive clicked down, reported up, time-to-report down; the submit rate matters more than the click rate; the report rate matters most. Read the trend, not the snapshot — a rising report rate can coincide with a temporary click-rate rise (more engaged = more email interaction).
Extends a tiny central team org-wide; local trust; ground-truth
Insider threat (intro)
Accidental insider (most incidents) → directly reduced by awareness/culture.
Malicious insider → needs access controls (Part IV), monitoring/UEBA (the security-operations work, Part V), HR processes; positive culture helps at the margin.
Defense in depth across layers (Theme 4)
Technical email controls (SPF/DKIM/DMARC, Ch. 9) reduce the volume reaching inboxes; the human program handles what gets through. Neither alone is sufficient; together far stronger. BEC/vishing (clean emails, phone pressure) cannot be filtered — the human layer is the only defense.
