Users increasingly access corporate data from their own devices and public wireless networks such airports Wi-Fi or coworking offices. On one hand, more work is possible, but on the other hand, it is riskier because the devices and locations may be untrustworthy. However, the Bring-Your-Own-Device trend is a fact and it is the reason we survey in this paper how computational trust and risk metrics may help mitigating those new risks in a more dynamic way than in the past. An online survey that we have carried out confirms that users do not take care of security risks as they are communicated today and that new Human Computer Interfaces combined with opportunity-enabled risk management are needed to improve the situation.
