Or perhaps the question should be; “Can’t be bothered to change your QSA?“
Or an even worse scenario; you know you can’t change your QSA because the new one might discover things you’ve been hiding from the last one!
I can almost empathise with the first two, but if it’s the third scenario you deserve the bad things that will happen when you get breached.
The fact is, if you have been working with a good QSA, not one of the challenges I list below will apply to you, Changing QSAs, or even QSA companies will not be an issue. You will have been doing security properly, and not just faking compliance.
A significant number of organisations are faced with at least 1 of these 5 main challenges;
- Lack of Continuity – Employee attrition is inevitable. QSAs have historically bounced from one QSA company to the next following the money. Which has been abundant for almost a decade now. This has left many clients in the unfortunate position of having to start all over again with another QSA. Often one who has received little to no hand-over.
- Lack of Guidance – This is the QSA’s only real job. Other than writing the second half of the Report on Compliance, ALL of the remediation work belongs to the client. The role of the QSA is to ensure that the client NEVER hits a roadblock. QSAs are supposed to have ‘been-there-done-that’, so “What’s next?” should never be a question the client has to ask.
- Inconsistent Opinions – Every security consultant has a different skill-set. Some are network wizards, others know encryption, most should be very familiar with policies and procedures. What happens when your last QSA agreed something that your current QSA won’t accept? Who is accountable for the loss of resource and/or capital cost?
- Starting Over Again Every Year – Too many QSAs are ‘just QSAs‘, with little experience or capability in fitting PCI into sustainable security processes. If your PCI compliance looks like an annual project, it is. Validation of compliance should be a simple process that should fit neatly into your BAU program. If it doesn’t, there’s a very good chance your QSA is at least partially to blame.
- Black-Hole Communications – If you expect your QSA to be a project manager, you have completely misunderstood the dynamic. But if you expect them to respond to emails requesting guidance in a timely fashion, you should. A QSA is there to tell you everything you have to do to achieve compliance, that’s their job, they must be readily available.
OK, so those are all the bad things, how do you fix them? Easy, choose the right QSA in the first place!
Facetious yes, and likely a moot point, but it’s never too late to change:
- For Lack of Continuity – All good QSAs have a methodology; Have you seen it? Does you QSA even have one? If the answer is no, you don’t have a good QSA. Continuity is simple, it just requires discipline, and a plan.
- For Lack of Guidance – As stated above, this is the QSA’s only purpose, if they can’t provide it, find someone who can. Interview your QSA(s) before letting them onsite, but have your questions prepared. Insist on having access to QSAs suitably qualified in ALL 12 DSS Requirements. You’ll never find this in a single QSA, unless it’s one of the 3 that I know that come close (I’m not one of them).
- For Inconsistent Opinions – Agree a process whereby the QSA company accepts mitigation plans or compensating controls, not individual QSAs. Agree, in writing, that ALL QSAs they send will accept a company approved option.
- For Starting All Over Again – This is as much your fault as the theirs. If you had a security program in place that appropriately covered your business, PCI would fit into it, not the other way around.
- Black-Hole Communications – Vendor Due Diligence + Service Level Agreements + Vendor Management. Period / Full Stop.
Changing QSAs every few years is a best practice, you should ALWAYS want fresh eyes on such a critical process. If changing your QSA is too difficult or inconvenient, it says a lot about both your current QSA, and your organisation’s attitude toward security;
They both leave a lot to be desired.
Here’s some old guidance I threw together a while back; Selecting the Right QSA for Your Business
