This is not entirely true. Desktop and Server protector can actually do
*almost* everything server sensor does. You can turn off and modify
detection, exactly the same as server sensor. You can even feed trons
sigs to desktop protector products.
The key to desktop/server protector is the numerous parameters. Using
the parameters you can do customize virtually every signature and every
IDS threshold. Download the document Desktop Protector Advanced
(http://documents.iss.net/literature/BlackICE/BI-AAG.pdf) and learn
Using those and the custom section of ICEcap, you can tweak, tune, and
reconfigure your Desktop/Server protectors. For example, you can change
logon thresholds and suppress port probes.
Another trick in desktop/server protector is to use the application
control features as a "tripwire-esque" file monitor. It takes some
customization, but when its up and running, its very cool. Anytime a
hashed file changes, the report goes to ICEcap/Siteprotector but does
not stop the application. See my white paper:
As for trons help - see: http://www.robertgraham.com/pubs/ids/trons.html
I usually tell customers that desktop/server protector is very powerful
solution that can be used at a very advanced level, but you have to be
willing to crawl under the covers of the product and look past the
Server sensor has more features and capabilities (like OS monitoring),
but it's a heavier solution. Desktop has limitations, no question about
that, but it does cost a bit less. . You also can use ICEcap with the
desktop product, which is thinner and lighter than Site Protector (IMO).
Please note: I have a bias toward the desktop products, namely because I
was the original author of all the tech docs back at Network ICE (I do
NOT write the docs anymore) and I helped design some of ICEcap's
features. I also do a LOT of ICEcap/desktop protector consulting work.
