Security consultancy from the other side

I used to run an application security consultancy business, back before the kinds of businesses who knew they needed to consider application security had got past assessing creating mobile apps. Whoops!

Something that occasionally, nay, often happened was that clients would get frustrated if I didn’t give them a direct answer to a question they asked, or if the answer to an apparently simple question was a one-day workshop. It certainly seems sketchy that someone who charges a day rate would rather engage in another day’s work than write a quick email, doesn’t it?

Today I was on the receiving end of this interaction. I’m defining the data encryption standards for our applications, so talked to our tame infosecnician about the problem. Of course, rather than specific recommendations about protocols, modes of operation, key lengths, rotation frequencies etc he would only answer my questions with other questions.

And this is totally normal and OK. The reason that I want to encrypt (some of) this data is that its confidentiality and integrity are valuable to me (my employer) and it’s worth investing some of my (our) time in protecting those attributes. How much is it worth? How much risk am I willing to leave on the table? How long should the data be protected for? Who do I trust with the data, and how much do I trust them?

Only I can answer those questions, so it’s not up to someone else to answer them for me, but they can remind me that I need to ask them.
