These are the default base profiles at the time of writing. 

Select Anti-X > ADP > Profile.

Figure 399   Anti-X > ADP > Profile

The following table describes the fields in this screen. 

 

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.

Table 166   Base Profiles 

all

All traffic anomaly and protocol anomaly rules are enabled. Rules with a high or 
severe severity level (greater than three) generate log alerts and cause packets 
that trigger them to be dropped. Rules with a very low, low or medium severity 
level (less than or equal to three) generate logs (not log alerts) and no action is 
taken on packets that trigger them.

none

All traffic anomaly and protocol anomaly rules are disabled. No logs are generated 
nor actions are taken.
