大多数人认为安全威胁会立即显现，但作者认为许多攻击是经过精心设计的，会延迟激活或在特定条件下才触发，因为攻击者采用渐进式策略来避免被检测。这挑战了人们对即时威胁检测的假设。

A good word for the particularly insidious efforts of child labor at the time. To encroach:"to enter by gradual steps or by stealth into the possessions or rights of another." Thank you Merrian Webster. Word Origin information includes "The history behind "encroach" is likely to hook you in. First appearing in English in the 16th century, the word derives from the Middle English "encrochen," which means "to get or seize." The Anglo-French predecessor of "encrochen" is "encrocher," which was formed by combining the prefix en- ("in") with the noun "croche" ("hook"). "Croche" also gave us our word crochet, in reference to the hooked needle used in that craft. "Encroach" carries the meaning of "intrude" both in terms of privilege (as demonstrated in our first example sentence) or property (as in our second example sentence). The word can also hop over legal barriers to describe a general advancement beyond desirable or normal limits (such as a hurricane that encroaches on the mainland)."
