T23: Human in the loop: Exploring human vulnerabilities of authentication

Half Day Tutorial

Dr Theo Tryfonas (short bio)
Bristol Cryptography Group, University of Bristol, UK


To discuss human aspects of authentication process design, explore the reasons of human-related failures, provide examples of relevant vulnerabilities, misconceptions and ill defined authentication schemes that facilitated exploitation of human factors. The discussions will enable interface designers, system analysts, IT managers and other key stakeholders to understand essential human-centric aspects of computer security, especially as far as authentication (i.e. establishing and verification of someone'e identity) is concerned.

Content and benefits:

The tutorial will cover aspects of cognitive biases of password, PIN and lock pattern setting by end users, it will explore the design obstacles to password policy compliance, 'soft' side channel attacks (i.e. when information is leaked through interactions with people using the system, as opposed to attacking the system directly), social engineering as well as state of art countermeasures of usable security. We will also discuss ways that security measures can be enacted successfully within the context of an organisation, causing least disruption to business operations, looking at examples of effective designs as well as end user awareness campaigns.

Target Audience:

requirements engineers, software designers, human-computer interface specialists.
