IoT and Security Munich Internet Research Retreat Raitenhaslach (MIR^3) 2017 Raitenhaslach, 23 rd May 2017
Why care? • Collateral damage / DDoS attacks
Regulatory • Mandatory firmware update • End of life – Inform customers (e.g., sticker on the device) • Do we need a remotely executed IoT TUeV? • Scope of the guarantee for users about their devices (what gets updated)? • Example: Car safety – recall actions
Operational • Kill switch: under what conditions should a device be disabled? • Update of already deployed devices (not enough flash, RAM, etc.) • Segmentation of networks to sandbox devices. • How to identify malicious devices? – Example: Windows Defender (repository of security bugs and how to check for them)
Proxy & Edge Computing • Does it increase the attack surface? • How to authorize to act on behalf of cloud-based service? • How can services be executed securely? (role of hardware support) • How to know to trust other communication devices? (machine learning, attestation, ..)
The User • Incentive problems: devices work but cause problem on the Internet • How to inform users about security problems of their devices? • What should be the role of the operator to quarantine devices? Should the operator inform the user? • Does he pay for security? Do we need a new business model for IoT devices based on subscription?
