32.3.3 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
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.
