Rule Elements

A web security rule on the appliance has three main elements: criteria, action, and (optionally) event.

  1. Criteria

    Determines whether a rule applies.

     Other rule syntaxes use the term condition instead of criteria.

     Example in plain text:

     If the category of a URL is in list x ...

    The criteria has three elements: property, operator, and operand.

  • Property

    Is related to a web object or a user.

    ... the category of a URL ...

  • Operator

    Links the property to an operand.

    .. is in list ...

  • Operand

    Specifies the value of the property.

    ... x (list name) ...

              The operand is also referred to as parameter on the user interface.

  1. Action

    Is executed if the criteria is matched.

    ... block the URL ...

  2. Event

    Is executed if the criteria is matched.

    ... and log this action.

    An event is optional for a rule. A rule can have more than one event.

For more information, see Rule Format on the User Interface.
