Chapter 12: Setting Up Logging and Notification
200
WatchGuard Firebox System
Logging and notification are crucial to an effective network 
security policy. Together, they make it possible to monitor 
your network security, identify both attacks and attackers, 
and take action to address security threats and challenges. 
WatchGuard logging and notification features are both 
flexible and powerful. You can configure your firewall to 
log and notify a wide variety of events, including specific 
events that occur at the level of individual services. For 
more information on logging, see the following collection 
of FAQs:
Developing Logging and Notification Policies
When creating a logging policy, you spell out what gets 
logged and when an event or series of events warrants 
sending out a notification to the on-duty administrator. 
Developing these policies simplifies the setup of individual 
services in the WatchGuard Firebox System. If you have 
fully mapped out a policy, you can more easily delegate 
configuration duties and ensure that individual efforts do 
not contradict the overall security stance or logging and 
notification policies.
Logging policy
Specifically, the logging policy delineates: 
Which events to log 
Which service events to log
Which servers are allocated as log hosts
How large a log file is allowed to become and how 
often a new log file is created
In general, you want to log only the events that might indi-
cate a potential security threat, and ignore events that 
would waste bandwidth and server storage space. This 
generally translates into logging spoofs, IP options, probes,
