I really enjoyed Thom Langford’s recent post Three Envelopes, One CISO, on the old parable about preparing three envelopes to defer blame for bad things – until you cannot shift it, when you take the bullet.
In the CISO’s case it is likely to be a breach. So first blame your predecessor, though I have found that only works for about 6 months. If you get that long a honeymoon, then by the time you have been in the seat for 6 months it is your problem. For the second breach, blame your team. Of course this is limiting – you need them to work for you, but it’s a question of survival at this point, right?
When the third breach comes around, you prepare 3 new envelopes, because you are done. Though most folks only get one breach now – especially if they bungle the response. But that’s not Thom’s point, nor is it mine. He brings the discussion back around to the recent Sony breach.
Everyone seems to want to draw and quarter a CISO for all sorts of ills. It may be well-deserved, but the rush to judgement doesn’t really help anything, does it? Especially now that it seems to have been a highly sophisticated attack, which Mandiant called ‘unprecedented’.
So did the CISOs do themselves any favors? Probably not. But as Thom says,
We seem to want to chop down the CISO as soon as something goes wrong, rather than seeing it in the context of the business overall.
Let’s wait and see what actually happened before declaring his Career Is So Over, and also appreciate that security breaches are not always the result of poor information security, but often simply a risk taken by the business that didn’t pay off.
And with that I open the second envelope Rich gave me when I started at Securosis…
