前段时间看SQL Injection的时候遇到这两个词,今天查了一下,给大家参考一下。
False Negative Occurs when an actual intrusive action has occurred but the system allows it to pass as non-intrusive behavior.
False Positive Occurs when the system classifies an action as anomalous (a possible intrusion) when it is a legitimate action.
False negative A test result that wrongly shows an effect to be absent. False positive A test result that wrongly shows an effect to be present.
大概意思是False Positive把合法的判断成非法的了,False Negative把非法的判断成合法的了。主要是安全方面使用的。
