Die Hard is a Movie About Building Automation Insecurity. Discuss.

In this episode of the Security Ledger Podcast (#126): Die Hard has finally been embraced as the bloody, violent, feel-good Christmas movie its always been. But the film, which turns 30 this year, is about more than the power of ordinary guys to stand up to evil. Did you know it’s also a (very) early warning about the dire insecurity of building automation systems? We speak with Ang Cui of the firm Red Balloon Security about the dire risk of cyber attacks on building automation software and company’s work to secure this often-overlooked critical infrastructure.

Experts Propose Standard for IoT Firmware Updates

Bleeping Computer reported that a new proposal submitted to the Internet Engineering Task Force (IETF) defines a secure framework for delivering firmware updates to Internet of Things (IoT) devices. Insecure software updates for embedded devices (aka ‘firmware’) have been a frequent source of security lapses on mobile and embedded devices like Internet connected webcams. Filed on October 30, the “IoT Firmware Update Architecture,” establishes security requirements for device makers to implement when designing firmware update mechanisms for connected devices. A familiar list of features The proposed rules include features that have long been recommended by security experts to permit safe handling of software updates. Among them the use of cryptographically signed updates and public key cryptography to provide end-to-end security and verify firmware images, as well as the ability to work with low-power and resource constrained IoT devices. Firmware has been the source of widespread security issues. For example, low-cost […]
