In defence of the human factor

Since Kevin Mitnick coined the phrase in 2002, the cybersecurity industry has been awash with the phrase 'the human factor is the weakest link’. From vendors to researchers, engineers, hackers, and journalists, we are all fond of blaming the ‘dumb users’. In this talk I argue that when we say that the ‘human being is the weakest link in cybersecurity’, not only are we telling a lie, we are inevitably setting ourselves up for a fall.

In defence of the human factor

  1. 1. IN DEFENCE OF THE HUMAN FACTOR Dr Ciarán Mc Mahon Tivi Digital & Cyber Security, Scandic Park, Helsinki, 24.11.2016
  2. 2. Introduction • Today’s talk • The so-called ‘weakest’ so-called ‘link’ • The ETTO principle • Everything is broken • Victim-blaming • Building a positive cyber security culture
  3. 3. About me Dr Ciarán Mc Mahon is a director of the Institute of Cyber Security and an award-winning academic psychologist from Ireland. A former Government of Ireland Scholar, he has published research on the history of psychological language, the psychology of social media, digital wellness and the social impact of cybercrime. Ciarán has worked at a number of third level institutions, and is currently an occasional lecturer at University College Dublin. Ciarán also has extensive media experience and regularly contributes on topics relating to the human aspects of information technology to national and international outlets including Sky News, BBC Radio London, USA Today, Fortune Magazine, and The Guardian.
  4. 4. The Institute of Cyber Security aims to help companies and organisations develop the most resilient cyber security culture possible.

  10. 10. What about the other links in the security chain? Are they really stronger, and more secure?
  11. 11. ‘Everything is broken’ Quinn Norton It’s hard to explain to regular people how much technology barely works, how much the infrastructure of our lives is held together by the IT equivalent of baling wire. Computers, and computing, are broken.
  12. 12. Update of the art Recent patches o 16 updates of iOS in the last year o 3 Flash updates in a single month o How quickly did Windows 8 become Windows 8.1?
  13. 13. Update of the art Recent patches o Only 7.5% of all Android devices are running its most secure operating system o This is currently being investigated by the US Federal Trade Commission
  14. 14. ‘Another flaw in the human character is that everybody wants to build and nobody wants to do maintenance’
  15. 15. So why are we blaming people for security problems, when the technology is falling apart?
  16. 16. Acceptable accident causes (Hollnagel & Amalberti, 2001) Accidents are always found to have been o associated with a system structure o which can be reduced within accepted limits of cost and time o conforms to current “norms” for explanations
  17. 17. Human error is a meaningless concept Every day the average office worker clicks on hundreds of hyperlinks as part of their job. But one day, they click on the wrong one, and suddenly they’re the cause of malware infection. Hollnagel’s (2006) ETTO principle – ‘efficiency-thoroughness trade-off’ Sometimes things go wrong, sometimes things go right.
  18. 18. The flipside o We say that ‘the human factor is the weakest link in cybersecurity’ because it’s a lot easier than tackling the real problem o the fact that IT is falling apart o But that’s not the only reason we shouldn’t say ‘the human factor is the weakest link in cybersecurity’

  20. 20. But how can you expect your employees to listen to you when you are assume that they are stupid or untrustworthy?
  21. 21. But how can you expect your employees to listen to you when you are assume that they are stupid or untrustworthy? WE NEED TO CHANGE HOW WE TALK ABOUT HUMAN FACTORS IN CYBERSECURITY
  22. 22. Victim blaming (Cross, 2015) Discourse on online fraud is based on idea of greedy/gullible victims o does not take into account level of deception and sophisticated targeting o humour isolates victims and impacts their ability to warn others
  23. 23. Understanding abusive insiders Posey, Bennett, & Roberts (2011) : o employees who do not feel that their organisations trust them will engage in more computer abuse when security measures are brought in
  24. 24. Organisational justice and fairness Bulgurcu, Cavusoglu, & Benbasat (2009): o creating a fair environment and ensuring procedural justice in regards to implementing security rules and regulations is the key to effective information security management.
  25. 25. Are CISOs their own worst enemy? (Ashenden & Sasse, 2013) CISOs struggle to gain credibility due to: o confusion about their role identity o inability to engage effectively with employees
  26. 26. If we want our colleagues, co-workers and corporate level executives to engage with cybersecurity policy, we have to stop seeing them as the weakest link. We have to start engaging with them, trusting them, and educating them. It’s that simple.
