cd-rw usage

Hi,

Can anyone advise on the best way to monitor usage of cd-writers though DLP, just to see who is using them, and if possible what they are writing (just the file names) ?

thanks.

Re: cd-rw usage

You have to create a Device Definition in DLP Policy for CD/DVD drives.

then you have to create a Device Rule and include the CD/DVD drives and set it to Monitor.

Now, you can either use Active Directory and create a User Access Group under DLP Policies and add the "Everyone" group or you can create a DLP Computer Assignement Group policy and assign it to the root of your System Tree.

These should tell you when a CD/DVD is accessed on a computer.

That being said, it wont tell you if files were copied to or from the CD and it wont track which files were burned.

Its best to just create a CD/DVD Device rule and make all the devices read-only and create a security group in AD to put authorized users into.  Your CIO should write up a policy for this.

Re: cd-rw usage

You need to do an inventory of the cd/dvd burner applications and identify the processes that access the disk when writing files. process monitor is a goot tool for doing this http://technet.microsoft.com/en-us/sysinternals/bb896645.aspx

One you have a list of the applications, you can create an application protection rules that monitor the cd/dvd writing processes that access data from the disk. The downside is that if someone writes a lot of files, you'll get a hell lot of events. (one per file)

Using device control rules will create one event when the system boots and loads the cd/dvd drivers, but that's about it, you don't get information about what was copied. Removable storage protection rule doesn`t cover the cd/dvd.
