Case Study: Implementing a Centralized Logging Facility
During the past several years I have found that there is an increase use in the number of Windows based systems appearing in our predominately all UNIX environment. This has been a downfall especially since UNIX and Windows systems are so different with regards to logging facilities, UNIX with its syslog facilities and Windows Eventlog; therefore I needed to find a way so that our Windows and UNIX systems could utilize a more robust logging facility. With budget concerns, being a major contributing factor, I needed to find a solution that was inexpensive. Therefore all the items that I chose to implement at this time are freeware and applications that already exist in our environment. The Windows systems needed to be configured so that they would audit the proper events and then forward that onto a UNIX system for storage and eventually analysis. Next, the UNIX systems needed a bit of tuning to get syslog to log the correct items. Finally, the logs needed to be retained and rotated. After these steps the logs can then under go further forensics and alerting of specific events. This document will provide all the necessary information needed to configure a centralized logging facility for Windows and UNIX systems including configuration of Windows eventlog, auditing, and UNIX syslog.
