    DLP 9.3 & USB Copy Slowness with Removable Storage Protection

    robg3381

      We're relatively newer to DLP and upgrade from 9.2 to 9.3 a month or so ago.  We recently switched our policy to full protection mode and now users are complaining of slowness when doing file copies.  From talking to Platinum support, this is due to the fact that DLP scans all the files for content before it allows it to copy to the device.  In some of the cases, we have real business needs to copying this data to the drives so the users need to be able to perform this in a decent amount of time.  In some cases, they may copy 50MB to a USB drive and at times it will take 8 minutes or so due to the number of files being copied, etc.

          

      How can we better manage this so we don't alienate the userbase?

       

      Our intent is to scan documents and all files and log it (not block), without impacting users as much as possible.

       

      Any advice or guidance is much appreciated!

          8 minutes for 50MB sounds like a lot. Are these zip files?

          Depending on whether you are using Tags or Content Categories and other configuration items in the policy, there may be scope for improvement.

           

          In order to scan files, depending on the system hardware the application is going to take some time.

          It eventually comes down to this: Security vs. Usability. If you want to be more secure, be prepared for some delays / performance impact (just like with any other security product, e.g. antivirus).

          As long as there is good Governance in place i.e. backing from the Management Team on the data protection initiatives (the way it is supposed to be) and security awareness training, users would eventually understand why companies need to protect their data (and how that affects performance).

            The files were a proprietary image files (not common image files like jpg, tiff, etc).  We are using content categories for that as well.  I do understand this is as designed and is more secure...I do get it and do agree.  However due to the nature of our business, we have many staff that copy data to/from USB and/or manipulate data on USB devices often.  So our intent is to be as transparent as possible and mainly to allow our staff to keep doing their jobs.  So I was wondering how others manage this or if everyone just enables it and forces their users to accept it.  Thanks again for everyone's comments and suggestions!

              I wouldn't be surprised if in your case the delay is because of a bug. 8 minutes for 50MB sounds a lot to me. What interests me more is that the files are proprietary image files.

              Unless these files contain content there is nothing for DLPe to analyze.
