Etymology: The term "white hat" for an ethical hacker draws on a long Western habit of using hat colours to signal moral character. In early Western films, heroes often wore white hats and villains black ones, and that visual shorthand carried over into computing. The "white hat" label distinguishes security researchers who find flaws in order to fix them from those who exploit those flaws for harm, who are called "black hats." The compound itself is simply "white" and "hat" joined into one word, with the spelling "whitehat" being an alternative form of "white hat." Because it is a plain combination of two everyday English words, its meaning comes directly from the colour symbolism rather than from any specialised technical root.

Synonyms: ethical hacker, security expert
