Theresa works for a company that handles a fair bit of personally identifiable information that can be tied to health care data, so for them, security matters. They need to comply with security practices laid out by a variety of standards bodies and be able to demonstrate that compliance.
There's a dirty secret about standards compliance, though. Most of these standards are trying to avoid being overly technically prescriptive. So frequently, they may have something like, "a process must exist for securely destroying storage devices before they are disposed of." Maybe it will include some examples of what you could do to meet this standard, but the important thing is that you have to have a process. This means that if you whip up a Word document called "Secure Data Destruction Process" and tell people they should follow it, you can check off that box on your compliance. Sometimes, you need to validate the process; sometimes you need to have other processes which ensure this process is being followed. What you need to do and to what complexity depends on the compliance structure you're beholden to. Some of them are surprisingly flexible, which is a polite way of saying "mostly meaningless".
Theresa's company has a process for safely destroying hard drives. They even validated it, shortly after its introduction. They even have someone who checks that the process has been followed. The process is this: in the basement, someone set up a cheap drill press, and attached a wooden jig to it. You slap the hard drive in the jig, turn on the drill, and brrrrzzzzzz- poke a hole through the platters making the drive unreadable.
There's just one problem with that process: the company recently switched to using SSDs. The SSDs are in a carrier which makes them share the same form factor as old-style spinning disk drives, but that's just a thin plastic shell. The actual electronics package where the data is stored is quite small. Small enough, and located in a position where the little jig attached to the drill guarantees that the drill won't even touch the SSD at all.
For months now, whenever a drive got decommissioned, the IT drone responsible for punching a hole through it has just been drilling through plastic, and nothing else. An unknown quantity of hard drives have been sent out for recycling with PII and health data on them. But it's okay, because the process was followed.
The compliance team at the company will update the process, probably after six months of meetings and planning and approvals from all of the stakeholders. Though it may take longer to glue together a new jig for the SSDs.
