This is plain sloppyness.

We use removable hard drives....................flash drives are not allowed. The HDDs lock into the computer. When you have finished you unlock the drive, remove it from the computer and lock it into a security cabinet or safe.

CDs and DVDs are controlled in the same way as paper documentation, and you have to sign for it and account for it.............the MoD do audits.

It is not permitted to have the "secure network" attached to the internet, that is only allowed for the unsecured network.
