“They’re requirements, Jim, but not as we know them” -
managing usability and security requirements during the development process
Angela Sasse, University College London
The need for more usable security solutions was established by 2 papers published in 1999 – Whitten & Tygar’s “Why Johnny Can’t Encrypt” and Adams & Sasse’s “Users Are Not The Enemy”. But 15 years on, there are still few examples of software that is secure and usable, and many with security that users either ignore or bypass. Based on an as yet unpublished study, I will argue that not eliciting and specifying security and usability attributes in sufficient detail at the requirement stage is the cause of the problem, and discuss what changes to processes and tools should be made to overcome this.
