Danux,

The PCI Auditor would confirm that the audit logging is in place for all
access to the segmented network and it is an acceptable form of network
segmentation. Furthermore, he/she would validate that the log host is
secure as if required it is needed for the forensics and log host is a
key hacker's target as they don't want to be caught and want to erase
their footprints by dry-cleaning the logs.

All the best.

Subject: PCI Compliance Scope

Question for PCI experts:

During a PCI Audit the Auditor told us that all the Security Devices
protecting Cardholder Data are also part of PCI Scope, which makes
sense for IDS/IPS, FW, AD, so on but what about a Log Management tool?

This means that my Log Management Centralized Server solution which is
getting logs not just for PCI assets but for the whole network ... is
gonna be in scope?
if so? This means all 300 security devices sending the logs (Servers,
WStations, Data Bases, AV) to the Centralized server are in scope Too?

if so?

Then, obviously I need to find a way to isolate & split the Log
Management Server from the whole network to only monitor PCI assets
but that entails to buy a new costly license to have another
Centralized log server, which is not doable for us.

Have you ever had the same problem? so that you can share the way to
resolve it WITHOUT adding new software/hardware?

I think I need to create a kind of PCI Security Devices Zone isolated
from the network but not sure if that works for PCI Auditor.

Please share your ideas.
