Two new "How-To" Videos on Event Monitoring

Wed, 21 Jun 2017 14:02:26 GMT

I just released two new "How-To" video's on monitoring two important areas with Windows Event Collection.

Video 1 - In this 4 minute video, I show you step-by-step how you can use my latest product, Supercharger, to create a WEC susbscription that pulls PowerShell security events from all of your endpoints to a central collector.

Video 2 - In this 8 minute video, you will learn how to monitor security event ID 4688 from all of your endpoints. Obviously this would normally create a plethora of data but using Supercharger's Common System Process noise filter you will see how you can leave 60% of the noise at the source.

You can watch the video's by clicking on the links above or visiting the resources page for Supercharger by clicking here.

Download Supercharger Free Edition for Easy Management of Windows Event Collection

Wed, 14 Jun 2017 08:59:58 GMT

We just released a new and free edition of Supercharger for Windows Event Collection which you can get here

There are no time-outs and no limits on the number of computers you can manage with Supercharger Free.

I wanted to include more than enough functionality so that anyone who uses WEC would want to install Supercharger Free right away.  For non-WEC users, Free Edition helps you get off the ground with step-by-step guidance. 

With Supercharger Free you can stop remoting into each collector and messing around with Event Viewer just to see the status of your subscriptions.  You can see all your collectors, subscriptions and source computers on a single pane of glass – even from your phone.  And you can create/edit/delete subscriptions as necessary.

I also wanted to help you get more from WEC’s ability to filter out noise events at the source by leveraging my research on the Windows Security Log. 

Supercharger Free Edition:

  • Provides a single pane of glass view of your entire Windows Event Collection (WEC) environment across all collectors and domains
  • Virtually eliminates the need to remote into collectors and wrestle with Event Viewer.  You can manage subscriptions right from the dashboard
  • Includes a growing list of my personally-built Security Log noise filters that help you get the events you need while leaving the noise behind

The manager only takes a few minutes to install and can even co-exist on a medium loaded collector.  Then it’s just seconds to install the agent on your other collectors.  You can uninstall Supercharger without affecting your WEC environment. 

I hope Supercharger Free is something that saves you time and helps you accomplish more with WEC.

This is just the beginning.  We’ve got more exciting and free stuff coming.  But you’ll need at least Supercharger Free to make use of what’s next, so install it today if you can.

Thank you for supporting my site of the years.  Here’s something new and free to say thanks.

How to Monitor Active Directory Changes for Free: Using Splunk Free, Supercharger Free and My New Splunk App for LOGbinder

Fri, 02 Jun 2017 17:11:59 GMT

No matter how big or small you are, whether you have budget or not – you need to be monitoring changes in Active Directory.  There are awesome Active Directory audit solutions out there.  And ideally you are using one of them.  But if for whatever reason you can’t, you still have AD and it still needs to be monitored.  This solution helps you do just that.  

Yesterday during my webinar: How to Monitor Active Directory Changes for Free: Using Splunk Free, Supercharger Free and My New Splunk App we released a version of our Splunk App for LOGbinder.  Not only is this application free, but with the help of our just announced free edition of Supercharger for Windows Event Collection, we demonstrate the power of WEC’s Xpath filtering to deliver just the relevant events to Splunk Free and stay within the 500MB daily limit of Splunk Light’s free limitations.  It’s a trifecta free tools that produces this:
 

Among other abilities, our new Splunk App puts our deep knowledge of the Windows Security Log to work by analyzing events to provide an easy to use but powerful dashboard of changes in Active Directory.  You can see what’s been changing in AD sliced up

by object type (users, groups, GPOs, etc)
by domain
by time
by administrator

Too many times I see dashboards that showcase the biggest and highest frequency actors and subjects but get real – most of the time what you are looking for is the needle – not the haystack.  So we show the smallest, least frequent actors and objects too.  


 
Just because it’s free doesn’t mean it’s low value.  We put some real work into this.  I always learn something new about or own little AD lab environment when I bring this app up.  To make this app work we had to make some improvements to how Splunk parses Windows Security Events.  The problem with stuff built by non-specialists is that it suffices for filling in a bullet point like “native parsing of Windows Security Logs” but doesn’t come through when you get serious about analysis.  Case-in-point: Splunk treats these 2 very different fields in the below event as one:


 
As you can see rsmith created the new user cmartin.  But checkout what Splunk does with that event:


Whoah! So there’s no difference between the actor and the target of a critical event like a new account being created?  One Splunker tells me they have dealt with this issue by ordinal position but I'm frightened that actor and target could switch positions.  Anyway, it’s ugly.  Here’s what the same event looks like once you install our Splunk App:


That’s what I'm talking about! Hey, executives may say that’s just the weeds but you and I know that with security the devil is in the details.  

Now, you knowledgeable Splunkers out there are probably wondering if we get these events by defining them at index time.  And the answer is “no”.  I provided the Windows Security Log brains but we got a real Splunker to build the app and you’ll be happy to know that Imre defined these new fields as search time fields.  So this works on old events already indexed and more importantly doesn’t impact indexing.  We tried to do this right.

Plus, we made sure this app works whether you consume events directly from the Security log of each computer or via Windows Event Collection (which is what we recommend with the help of Supercharger). 
 
To learn more about the over all solution please watch the webinar which is available on demand at https://www.ultimatewindowssecurity.com/webinars/watch.aspx?ID=1439

For those of you new to Splunk, we’ll quickly show you how to install Splunk Free and our Splunk App.  Then we’ll show you how in 5 minutes or our free edition of Supercharger for Windows Event Collection can have your domain controllers efficiently forwarding just the relative trickle of relevant change events to Splunk.  Then we’ll start rendering some beautiful dashboards and drilling down into those events.  I'll briefly show you how this same Splunk app can also analyze SharePoint, SQL Server and Exchange security activity produced by our LOGbinder product and mix all of that activity with AD changes and plot it on a single pane of glass.

Or checkout the solution page at https://www.logbinder.com/Solutions/ActiveDirectory where there are links to the step-by-step directions.

And if you are already proficient with Splunk and collecting domain controller logs you can get the Splunk app at https://www.logbinder.com/Resources/ and look under SIEM Integration.
