In one of my previous blogs, I covered the importance of logging the “right” events for an effective Log Management or Security Information and Event Management (SIEM) deployment … see here or here for a discussion on the two technologies. The blog also provided a suggested listing of the Windows or Active Directory events that you might want to log from a PCI DSS Compliance standpoint.
Clearly, no amount of investment in your Log Management or SIEM solution is going to do much good, unless you have been able to generate all the right logs to begin with … see a related discussion with the recognized PCI Expert and Author, Dr. Anton Chuvakin here.
I would like to extend my suggested list in the previous post to cover a few other systems here, specifically UNIX/LINUX, Network Devices and Databases. Note that this list is only a starting point so you can work with the respective System Specialists or Administrators in your organization to generate these events.
