30.7 Creating New 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.
30.7.1 Procedure To Create a New Profile
To create a new profile:
1 Click the Add icon in the Anti-X > ADP > Profile screen to display a pop-up screen

30.8 Profiles: Traffic Anomaly
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 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 belonging to this profile, make sure you have clicked OK or Save to
save the changes before selecting the Traffic Anomaly tab.
Base Profile This is the base profile from which the profile was created.
