This talk will address a fundamental challenge in information security: Authentication, or how to establish trust between a user and their collection of devices and internet services.
I will start by describing the current state of play: a regular user typically has at least one computer and a smartphone; each individual is then subscribed to tens or sometimes hundreds of Internet services which are accessed using these devices. Even these services are interconnected with trust relations, such as email accounts that receive password reset tokens. Some of these relations are not so obvious...
The complexity of this arrangement is rising so fast that it's getting harder for end users (even power users) to cope with all of its security implications. Most users will not have any strategy to manage their security, using the same password for all services and devices; but even most power users such as infosec professionals make mistakes that can be exploited.
I will illustrate the current scenario with a dissection of the Mat Honan hack and my own experience mapping the interconnections between my own devices and services.
I will then attempt to provide a strategy to schematize and improve the level of trust between users and devices / services, analysing ad-hoc strategies by power users and provide the tools to create a personal strategy.
Finally I’ll look into what the future of authentication, and what this Tangled Web might bring us: mutual authentication between devices, the future of two factor, the role of social networks, location based authentication, behaviour based trust, trust federation.
