Security Rule Matchers

Security Rule Matchers

Security rule matchers define the criteria that the Rule Engine uses to identify incoming SQL requests that receive the rule action.
The security rule matcher that you choose depends on the method you want the Rule Engine to use to identify SQL statements. For example, if you want to restrict access to a customer table, use the From Clause Object rule matcher with the Block Statement processing action. You can use the Text rule matcher to identify a specific text string within an SQL request or the symbol matcher to match a variable value, such as the session or client information. If you want to apply the security rule to all incoming requests, use the any matcher.
