The fatal flaw in IT Risk management

Is interviewing is a much better method that self-certifications and a checklist, if time and resources allow.
Two points:

In the ISO-27001 forum, my friend and colleague Gary Hinson has repeatedly pointed out, and I fully support him in this, that downloading check-lists from the ‘Net and adopting question lists from there is using a solution to someone else’s
problem. If that.

Each business has both generic problems (governments, sunspots, meteor strikes, floods & other apocalyptic threats and Acts of God) and ones specific to it way of working and configuration. Acts of God are best covered by prayer and insurance.

Gary recommends “open ended questions” during the interview rather than ones that require a yes/no answer. That’s good, but I see problems with that. I prefer to ask “Tell me about your job” rather than “Tell me how your job … can be made more efficient”.

My second point is that risk management will *ALWAYS* fail if the risk analysis is inadequate. How much of the RA should be done by interviewing people like the sysadmins I don’t know, but I have my doubts. I look to the Challenger Disaster. I started in the aviation business and we refines FMEA – failure Mode Effect Analysis. Some people think of this in terms of “impact”, but really its more than that, its also causal analysis. As Les Bell, a friend who is also a pilot and interested in aviation matters has pointed out to me, “Root Cause Analysis” no longer is adequate, failure comes about because of a number of circumstances, and it may not even be a single failure – the ‘tree’ fans both ways!

Yes, FMEA can’t be dome blindly, but failure modes that pertain to the business – which is what really counts — and the fan-in/out trees can be worked out even without the technical details. Rating the “risk”: is what requires the drill-down.

Which gets back to Donn Parker‘s point in a number of his books, though he never states it this way. The FMEA tree can be heavily pruned using diligence as he says: standards, compliance, contracts, audits, good practices, available products. The only thing he leaves out are Policy and Training. Policy gives direction and is essential to any purpose, the choice of standards and products, and identifying what training is needed.

All in all, the article at https://blog.anitian.com/flawed-it-risk-management/ takes a lot of words to say a few simple concepts.

 

What Applicants Should Ask When Interviewing For An InfoSecurity Position

http://www.informationsecuritybuzz.com/applicants-ask-interviewing-information-security-role/

Well what would you ask?

These seem to be the kind of questions that might be asked by someone with a strong technical bias. The CISSP cert is supposed to be more oriented towards security management than to the technical aspects, so what would you ask?

We should, I think, be asking about “The Tone At The Top“, the organizations attitude towards security and, but what does that mean in terms of interview questions?

My thoughts tend towards Policy and Certification, but them many of my past clients have been financial, so regulatory compliance looms large for them. I’d certainly ask about Policy, how it is formulated, how it is communicated and how it is enforced. That’s not as easy as it sounds: most people know what should be done but ask that tactlessly and other than being an opening (“Yes, I can work on that for you”) all you’ve done is embarrassed the interviewer.

So we have a refinement that the article never touched on: this is an interview not an audit.

 

Confusion over Physical Assets, Information Assets – Part Two

So I need to compile a list of ALL assets, information or otherwise,

NO!
That leads to tables and chairs and powerbars.

OK so you can’t work without those, but that’s not what I meant.

InfoAssetsPhysical assets are only relevant in so far as they part of information processing. You should not start from those, you should start from the information and look at how the business processes make use of it.  Don’t confuse you DR/BC plan with your core ISMS statements.  ISO Standard 22301 addresses that.

This is, ultimately, about the business processes. Continue reading Confusion over Physical Assets, Information Assets – Part Two

How to build an asset inventory for 27001

How do you know WHAT assets are  to be included in the ISO-27K Asset Inventory?

SOMF Asset Patterns

This question and variants of the “What are assets [for ISO27K]?” comes up often and has seen much discussion on the various InfoSec forums I subscribe to.

Perhaps some ITIL influence is need.  Or perhaps not since that might be too reductionist.

The important thing to note here is that the POV of the accountants/book-keepers is not the same as the ISO27K one. To them, an asset is something that was purchased and either depreciates in value, according to the rules of the tax authority you operate under, or appreciates in value (perhaps) according to the market, such as land and buildings.

Here in Canada, computer hardware and software depreciates PDQ under this scheme, so that the essential software on which you company depends is deemed worthless by the accountants. Their view is that depreciable assets should be replaced when they reach the end of their accounting-life. Your departmental budget may say different.

Many of the ISO27K Assets are things the accountants don’t see: data, processes, relationships, know-how, documentation. Continue reading How to build an asset inventory for 27001
