This section explains how to add normalization rules to an event source.

About normalization rules

Normalization rules are used for transforming events. After Kaspersky CyberTrace applies normalization rules to an incoming event, the event is processed using regular expressions.

There are two types of normalization rules:

  • Replacing rules

    Rules for replacing one character sequence with another.

  • Ignoring rules

    Rules for ignoring events that contain a character sequence.

If the replacing rules and ignoring rules are set, replacing rules are applied first and ignoring rules are applied second.

In the specified regular expressions, the asterisk (*) and question mark (?) are not treated as wildcard characters.
