单词本：illicit

最近看了不少信息安全相关的资料。因为信息安全涉及攻击、恶意、违法词汇，所以也遇到了很多描述负面的词。

比如 illicit 这个词出现在威胁分析中(Bodeau, McCollum, and Fox 2018)：

In the FFIEC IS Handbook, threats come from agents (referred to in other references as threat actors or adversaries) who are internal or external. They have different capabilities and motivations, which require the use of different risk mitigation and control techniques. Note that this characterization does not consider threats from nation-state sources, which might seek competitive intelligence but might also try to cause harm as a national security matter, whether illicitly or openly in coordination with other international conflict.

也出现在安全相关的论文中(De Hoz Diego, Madi, and Konstantinou 2024)：

We also assume that some compromised devices in the IoT deployment might be trying to perform lateral movement to weaponize other devices or trying to access exposed services illicitly.

这个词是由表示否定的in-/il-加上 licit 组成的。 licit 在拉丁语里是 licitus 也就是合法的 lawful 之意。那么 illicit 就是非法的意思。

比如the illicit sale of drugs毒品的非法贩卖，an illicit relationship 不正当的关系。

其实 license 也是源自 licitus 。有 license就是有一个合法的证件么。 license 的意思就是证件、驾照、证照、执照。
