Danux,

Is your log server transmitting or storing sensitive credit card data?
Is the log server strictly a "receiver" - does it have write access
to any of the devices which could be transmitting or storing card
data?

If there's no credit card info on the logs, and all of the devices
which are storing or transmitting card data are segmented away from
inbound access via the log server, then you should be able to keep it
outside of scope.

The goal is to look at vectors of attack. If you cannot get to any
sensitive data using the log server as a launching point (thanks to
firewalls, ACLs, etc) then it's segmented and not in scope.
