While we’re fighting for our security and privacy, some are being left behind. Traditional security models tend to rely on certain assumptions in order to work effectively. For example current solutions assume that the user is able to make configuration changes and is permitted to keep certain facts secret in order to authenticate to a service or device. For victims of domestic violence, their proximity to their attacker means that many security solutions are ineffective and, in some cases, even harmful to implement. This talk will explore cases where traditional security measures fail an already-vulnerable population and how we need to rethink our approach to security.
