29.7 Creating New Profiles

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

You may also find that certain signatures 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 IDP 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 signature.
