Proposals for recycling disks

As we have now confirmed that the contract with CCL specifically includes the requirement for them to safely dispose of disks, we are now in a position to amend and simplify our proposed policy.

  • We can expect CCL to safely to dispose of disks so there is no longer a need to routinely remove disks from desktop machines.
  • We should, however, wipe disks where we consider the data to be sensitive as a precaution prior to sending the disks to CCL e.g. for Admin staff desktops, most servers.
  • We should wipe any DICE desktop that is being reallocated as a self-managed machine.
  • Self-managed desktops being reallocated to another user for use as a self-managed desktop should have their disk wiped.
  • For self-managed desktops being reallocated as a DICE desktop, a re-install will suffice.
  • For self-managed servers being reallocated, a re-install should suffice.
  • For DICE servers being re-allocated to another Unit, a decision should be made at the time as to whether a re-install is sufficient.

We do, however, need to make sure that there is adequate auditability. We'll need to ensure that we receive some form of confirmation from CCL so that we can confirm that the machines that have been sent for disposal have been correctly dealt with. We do not appear to receive such confirmation at the moment.

The table below attempts to provide a summary. The rows represent the current type of machine and the columns represent its next purpose/destination.
