Logging (Non-)Resolution

So, after a few weeks of going back and forth with the vendor on the logging issues I described in a previous post, we came to the conclusion that the product does not support logging of DNS requests. There are no plans to include this feature at this time, and there is no way to work around/override. So, where does that leave this client? Flying somewhat blind, unfortunately.

There is a valuable lesson here. We're only as good as our logging, and we can't assume that a device is logging properly. We have to use a scientific approach and look at what the data tell us before we can know what is actually going on. It's a painful lesson, but an important one in the quest to "Know Your Network".

Lesson learned.
