About Operators
There are a number of arithmetic and string operators. The Not check box is an inversion operator that results
in a match for any value except the configured condition.
These operators can be used in conjunction with Anti-Evasive Measures. For example, you might use the
Equals String operator with Convert to Lowercase or Normalize URI Path in Anti-Evasive Measures.
Table 35 describes the available operators for use with rules.
