About Geordie Stewart
His award winning masters thesis at the Royal Holloway Information Security Group examined information security awareness from a fresh perspective as a marketing and communications challenge. In his regular speaking appearances at international information security conferences such as RSA, ISACA and ISSA he challenges conventional thinking on risk culture and communication.
In addition to senior security management roles in large UK organisations Geordie writes the security awareness column for the ISSA international journal.
I’m really looking forward to RSA Europe 2012 next week where I’ll be taking part in a debate about whether or not organisations should train their staff in security awareness. It is being organised by Acumin and the RANT community. Participating with me will be: Christian Toon, European Head of Information Risk, Iron Mountain Europe Thom Langford, Director Global Security…Details
What if much of our security advice to users was a waste of their time? What if some of it actually made users worse off? These are bold words but stay with me and let’s see where this goes. There will be some maths on the journey but it will be worth it I promise. Let’s look at passwords as an example. Many thousands of pages of security policy have been generated on creating strong passwords. It’s one of the most common subjects for security awareness. More letters, more numbers, make it longer and put a special character in it. Actually, most passwords don’t need to be strong, they just need to be difficult to guess which isn’t the same thing. Cormac Herley points out that password strength no longer has the critical role in security that it used to. It’s largely irrelevant since most systems now control the rate of password guessing attempts. For example only allowing five attempts every 30 minutes. In this scenario, the difference between 7 character and 8 character passwords is negligible if the system limits a brute force attack to 240 attempts per day. Modern authentication systems are much more likely to be compromised by password database disclosures, password re-use and key-loggers. Complexity does not assist with managing any of these threats. For years we’ve been focused on complexity and as a result users come up with combinations like “Password1” which meet our complexity rules but don’t effectively mitigate their risks. We need to change. We need to stop talking about password complexity and start talking about password commonality. Potentially, we’re doing more harm than good by occupying valuable (and limited) attention spans with topics of marginal return. The risks have changed and our risk communication needs to reflect that.Details
I’ve contributed a posting on password strengths as an engineering problem rather than an an awareness problem on the SANS Securing The Human Blog. There’s a great quote from “Evil Dave” that sums up the problem rather well: “Through 20 years of effort, we’ve sucesfully trained everyone to use passwords that are hard for humans to remember, but…Details
Recently I co-authored a paper “Death by a Thousand Facts” with David Lacey for the HAISA conference where we explored the nature of how technical experts choose what content is included in risk communications. A copy of the proceedings is available here. Basically, mainstream information security awareness techniques are failing to evolve at the same…Details
Are humans rational? When we see computer users to silly things which place themselves or their information at risk its easy to take a view that people are illogical. The problem is that logic can’t be examined separately from perception.
There is significant debate within psychology literature as to the extent to which humans can be described as rational. Rationality is sometimes described as the ability for individuals to select the “best” option when confronted with a set of choices. The best option is also referred to as a “value maximising” option when the most benefit is obtained for the least expenditure of resources or exposure to risk.
The problem is that people routinely fail to select a “value maximising” option and exhibit apparently illogical behaviour. Commonly, an option mathematically modelled as the best choice by the technical experts isn’t the choice chosen by information system users when responding to risk.Details
