If tossing log data around in the DMZ is considered too risky, then a serial
(as in RS-232) connection can be made from the FW to the logging device. This
pathway can't be hacked through unless the logging device is compromised.
Downside, the logging device and the FW have to be placed at the same site.

[Ken Fox]  Another though is to configure a 3rd interface and dedicate that to your logging output to a specific 
machine on a specific port. That machine aggregates and/or processes the logs, and is much less hackable. 
(theoretically)  -- now assuming that the interface between the logging box and the firewall(s) is only susceptible to 
being flooded, thereby crashing the logger, then that system is not *really*  a link to the inside network; 
additionally the 3rd IF would be configured such that it was not trusted. Inorder to use the data from the log box, 
you'd either need to deal with it only on that box, or have a 2nd interface there which would allow you to export the 
data to what ever machines / people you needed to.
