Currently I am having an issue with not knowing information about the servers I am responsible.   I am not happy not knowing things.  I spent a little time gather different parts of different scripts (hacker / script kiddie style) and compiling them in to one Visual Basic Script.  This script is designed to work against Dell Servers.  It will ask the computer for it name, the OS, OS version number, Service Packs, Bit Level (32 or 64 bit), Dell Warranty info, list of local users, and a list of local groups and the users in the groups.  It takes the list of servers from “hosts.txt” which is just a list of servers or ip addresses where there is one per line.  It will write all the information it gathers in to a file called “report.txt”.

I have used OSSEC in the past to watch the file system for changes.  When I found that I can have the Splunk agent handle the monitoring itself, I was pretty excited.  Since I would send my OSSEC data to Splunk anyways, it just seemed logical to have Splunk do everything.

In Windows, you need to edit the “c:program filesSplunketcsystemlocalinputs.conf” file.  Of course your path could be different if you installed it in a different place.  There are a lot of options and switches you can use.  I went for the simplest set.

[fschange:d:temp]
recurse=true
pollPeriod=3600

This will monitor the d:temp folder and all files and folders under it.  It will check the system every 3600 seconds (1 hour).

This has helped me keep track of the changes in my servers.  I can see when a file was add/deleted/changed (due to the hash) and then look at who was logged in during the period that the file was changed.
