20 questions on cyber-supply chain risk management

I recently wrote an article for Banking Technology that has been generally well received, I’ve decided to include it here on the blog for future reference. I’ve enjoyed working with Banking Technology and thoroughly recommend the editor David Bannister who has clearly been around the block enough times and has a wealth of experience in the field.

Managing cyber supply chain risk is an unsolved problem that has increasingly drawn my attention as I discover new risks and new failures of risk management in this area. The OECD found that 73% of services traded in OECD countries are ‘intermediate’ services or services that are intermediate inputs into a final service or product that is consumed. That statistic lies behind some of my concerns regarding aggregation and correlation of risk within and between different sector supply chains that are not immediately obvious.

This also highlights the complexity of supply chains in the modern economy. I believe that supply chain cyber security in the age of industrialised and targeted cyber-attacks is a wicked problem [PDF] and that many of our current approaches to manage these risks do not address the nature of the underlying risks and instead focus on a fairly superficial view of the technological controls operated by ‘key’ suppliers. There are more innovative approaches being developed such as Red teaming suppliers or actively monitoring supplier cyber hygiene but I am not seeing these regularly being built into coherent cyber supply chain risk management strategies yet. I hope the high level article below goes some way to encouraging this.

Competing Innovations in Cyber

I have had a series of productive discussions with a colleague over the last year about the differences in adopting new innovations between cyber attackers and cyber defenders. His interesting, and itself innovative, contention is that a key problem in cyber security is created by the differently shaped innovation adoption curves between defenders and attackers. Also that by investing in changing the shape of defenders adoption curves the nature of the competition itself will be re-shaped. (I suspect I am doing my colleague something of a disservice with my summary).

Pitfalls of Cyber Data

I jointly presented with Ernest Li at 44con Cyber Security on April 28th 2015 discussing how we use public cyber data and some of the problems we have run into. My presentation is on slideshare below:

Security Analytics Beyond Cyber

I presented at 44con 2014 on moving security analytics on from network defense and rapid response towards supporting data-driven and evidence-driven security management, my presentation is on slideshare below:


Protecting Information About Networks, The Organisation and Its Systems

I recently wrote a report with a number of colleagues for the Centre for the Protection of National Infrastructure (CPNI) on the Network Reconnaissance phase of a targeted attack following initial exploitation. The report covers what is targeted, how the attackers operate and what controls help. Below is a summary infographic and below the cut is the briefing presentation I delivered and the full report.
