31.3.3 Creating New ADP Profiles

You may want to create a new profile if not all rules in a base profile are applicable to your network. In this case you should disable non-applicable rules so as to improve ZyWALL ADP processing efficiency.

You may also find that certain rules are triggering too many false positives or false negatives. A false positive is when valid traffic is flagged as an attack. A false negative is when invalid traffic is wrongly allowed to pass through the ZyWALL. As each network is different, false positives and false negatives are common on initial ADP deployment.

You could create a new ‘monitor profile’ that creates logs but all actions are disabled. Observe the logs over time and try to eliminate the causes of the false alarms. When you’re satisfied that they have been reduced to an acceptable level, you could then create an ‘inline profile’ whereby you configure appropriate actions to be taken when a packet matches a rule.

ADP profiles consist of traffic anomaly profiles and protocol anomaly profiles. To create a new profile, select a base profile (see Table 154 on page 517) and then click OK to go to the profile details screen. Type a new profile name, enable or disable individual rules and then edit the default log options and actions.

31.3.4 Traffic Anomaly Profiles

The traffic anomaly screen is the second screen in an ADP profile. Traffic anomaly detection looks for abnormal behavior such as scan or flooding attempts. In the Configuration > Anti-X > ADP > Profile screen, click the Edit icon or click the Add icon and choose a base profile. If you made changes to other screens
