You can use the Parser matcher with security rule actions to change the request. For example, if you want to block requests that Dynamic Data Masking cannot parse, you can create a rule with the following properties:

Rule Name

Enter a name for the rule. In this example, the rule name is parsed_statement.

Rule Matcher

Select the Parser matcher.

Rule Action

Select the Block Statement rule action. Enter a message that Dynamic Data Masking sends to the client when the statement is blocked. In this example the message is

UNABLE TO PARSE STATEMENT

.

Processing Action

Select Continue. The Continue processing action indicates that the Rule Engine should continue to the next rule in the rule tree.

Log When Rule is Applied

Select the

Log When Rule is Applied

check box to create an entry in the

rule.log

file if the Rule Engine applies the rule action to the request.
