The Consistency of Plastique

51lIxdlS2nL._SX300_As I said in my last post I have been travelling quite extensively recently, but this weekend I was able to take a long weekend in Oslo with my wife just before the Nordic CSA Summit where I was invited to speak on “the CISO Perspective”. As a gift for speaking, each of us was given a block of Norwgian cheese, in a roughly square shape, that really did seem to have the consistancy, weight and look of a lump of plastique (I imagine…). It did occur to me that in the spirit of all good 44CON prizes, it was intended to get you stopped at the airport.

On my return home yesterday, I was pret sure my bag would be picked up for secondary screening given the presence of this lump of cheesy explosive in my bag (although apparently @digininja tells me a malt loaf has the same effect as well). Sure enough, my bag was selected, I presented to the good natured security folks the block of cheese, and with a wry smile they let my bag through. The same could not be said of my carry on bag though.

5piecelockpicktoolI was asked quite curtly if I had a penknife or similar in this bag; now I am getting more forgetful, but I was pretty sure I hadn’t. The security guy really did not look like he believed me, so we started to empty my bag. Then I remembered, I had a pick lock set that I had put into  zipped pocket in my bag about nine months ago, intending to give it to my good friend Akash in Boston who had expressed an interest in that particular art. Remember I just said I am getting forgetful? That’s why it has been in my bag for so long having seen Akash many times this last nine months. Oh well.

But it also occurred to me that I had been through about ten different airports in that time, and this was the first time it had been picked up, let alone even identified as a possible penknife (understandable as the picks fold into the main body).

This underscores to me the inconsistency of the security scanning at virtually every airport. Shoes on or off? Belts on or off? IPads as well as laptops taken out? Kindles, in the bag or out? My bag of cables that you tell me to keep in my bag at one airport, and then getting admonished for not pulling it out of the bag at the next? As an end user of these services (and I am fully supportive of them despite this I must say) it is extremely frustrating. There seem to be too many exceptions in place without clear reason, and without tying back to a singular way of doing things. The shoe bomber, Richard Reid, saw to it we have to take our shoes off going through security… except of course when you don’t.

Consistency in an information security programme is obviously key. But sometimes the pendulum swings too far the other way. Any policy that ends with “There are no exceptions to this policy” is asinine at best,  and crippling to the business at worst. There will always be a need for an exception in order to ensure business can be carried out effectively. As long as the risks are understood and communicated effectively, then move on and do it.

It certainly doesn’t mean that the exception can be used as an excuse to carry on working like that. There is no concept of precedence in this case. If there was the natural end state would be complete mayhem as every exception is used to the point where there is no policy left. An exception is just what it says on the tin, a one off easing off the rules for business to to operate effectively and efficiently. It should be time based, must be reviewed regularly, and where possible repealed if alternative approaches have come to light.

Consistency is important when applying policies, especially across a large organisation, but for goodness sake, don’t forget that change is an important part of business and needs to be embraced. But please do a better job of managing that change, and the subsequent exceptions, than airport security does.

Conferences and Presentations

What with InfoSec Europe, BSides, RSA Unplugged and the just attended Nordic CSA Summer conference it has been busy on the presentation front again. I have a few more presentation to upload to this site as well as some footage. I am hoping to make it to Blackhat in Vegas for the first time this year, and speak on behalf of friendly vendor who I have always enjoyed working with.

Diligently preparing for the conference

As I also mentioned in my last post, my employer became a sponsor of the European Security Blogger Awards, something I hope we will be for future events as well. Unfortunately I lost my best personal blogger award crown this year to Lee Munson of Security faq’s. I can’t help but feel that if I have to lose to someone, Lee would be top of my list as he consistently outshines me in both quality and volume of blogging. As a community we are lucky to have someone like Lee and if you haven’t already done so please do reach out to him and congratulate him.
