Defining Matches For APE Rules
478
When creating your APE rules, you must specify the type of network traffic that you want
IDP to monitor for applications.
The match columns From Zone, Source, To Zone, Destination, and Service are required
for all rules in the APE rulebase. If IDP encounters a match for the other Match columns
in an APE rule, no other rules in the rulebase are examined. .
The following sections describe the Match columns of an APE rule.
Configuring Applications for APE Rules
You can select one or more applications to monitor network traffic originating from or
destined for any application.
To select or configure an application, right-click the Application column of a rule and

or custom application that you wish to add.
Configuring Source and Destination Zones for APE Rules (Does not Apply to
Standalone IDP Sensor Rulebases)
You can select multiple zones for the source and destination. However, these zones must
be available on the security devices on which you will install the policy. You can specify
"any" for the source or destination zones to monitor network traffic originating or destined
for any zone.
NOTE: You can create custom zones for some security devices. The list of zones from
which you can select source and destination zones includes the predefined and custom
zones that have been configured for all devices managed by NSM. Therefore, you should
only select zones that are applicable for the device on which you will install the security
policy.
Configuring Source and Destination Address Objects for APE Rules
In the NSM system, address objects are used to represent components on your network:
hosts, networks, servers, and so on. Typically, a server or other device on your network is
the destination IP for incoming attacks, and can sometimes be the source IP for interactive
attacks (see "Configuring Backdoor Rules" on page 486 for more information on interactive
attacks). You can specify "any" to monitor network traffic originating from any IP address.
You can also "negate" the address objects listed in the Source or Destination column to
specify all sources or destinations except the excluded objects.
You can create address objects either before you create an APE rule or while creating or
editing an APE rule. To select or configure an address object, right-click either the Source
or Destination column of a rule and select Select Address. In the Select Source Addresses
dialog box, you can either select an already created address object or click the Add icon
to create a new host, network, or group object.
