IBM Bans Staff From Using Removable Storage Devices (theregister.co.uk)

An anonymous reader shares a report: In an advisory to employees, IBM global chief Information security officer Shamla Naidoo said the company "is expanding the practise of prohibiting data transfer to all removable portable storage devices (eg: USB, SD card, flash drive)." The advisory stated some pockets of IBM have had this policy for a while, but "over the next few weeks we are implementing this policy worldwide." Big Blue's doing this because "the possible financial and reputational damage from misplaced, lost or misused removable portable storage devices must be minimised." IBMers are advised to use Big Blue's preferred sync 'n' share service to move data around.

      My company does similar. When we insert a USB thumb drive the system will prompt you to encrypt the drive, the encryption locks it to your machine only. If you say "Don't encrypt" then you are limited to Read only on the device, this is so we can download data from a client.

      At least our company has a procedure for obtaining an exception to the encrypted usb drive rule if you can justify it.

      Just use your phone as the USB drive. I work for a fortune 500 that uses the exact same technology and after asking one of the security analysts how it works, I quickly realized it would not recognize my phone as a removable storage device (it works based off the driver ID's used to interface with the device and thumb drives use a different driver than phones do.) I'm able to transfer files freely to my phone without issue.

      IBM is way too cheap for that... they would make him apply for a one off security exception to use a thumb drive explicitly with his old ass spectrum analyzer.

      He would still get to sit on his ass for two weeks while it got the necessary management approvals, though, and another week while IT figured out a why to circumvent their new security lockdown software without triggering nasty warning e-mails to his manager.

      But don't worry, those changes will magically disappear during the next software update, and he'll have to explain this to his NEW manager a few months down the road. Assuming that they don't just outsource the job to China first.

      We have had a similar policy to IBM's for a few years. A person who needs to use usb storage devices for things like you're talking about have to apply for security exceptions. Even if your employer grants a few thousand legitimate exceptions for stuff like this, they have still minimized risk by eliminating USB use by the other 200,000 employees. It does involve some overhead and time wasted when you first apply for your exception. In my opinion the benefit outweighs the drawback.

      It's a lot like changing a default security policy to DENY and only ALLOWing things you really want. Minor inconvenience in exchange for greatly improved security.

      Each USB device is identified independently of each other. If you plug in a USB keyboard that also has a USB port with a flash drive plugged in, the computer will see two different devices and only lock out the flash drive.

      If you are suggesting that someone can create a flash drive that the computer thinks is a keyboard, then the computer will not mount the drive to be written to since it knows that it cannot write data to a keyboard.

      This is a real attack vector that exists in the real world. Slashdot has covered this multiple times.

      Someone creates a device that looks like a flash drive.
      Internally, it is a keyboard, or a keyboard AND flash drive.
      When plugged in, even a "secured" system that blocks removable storage devices will typically allow other USB devices (such as keyboards).
      The OS will happily accept input from the thing as if it were a keyboard with keys pressed by a human, even though the key presses are all prerecorded payloads stored on the device.

      As such, the keyboard can go to town and so shit like:

      Windows Key
      cmd
      CTRL+SHIFT+Enter
      Left
      Enter
      del /f /s /q /*.*
