The biggest and most obvious security challenge with Internet of Things (IoT) devices is the inability to easily upgrade or patch them. The typical advice for avoiding cyber attacks continues to be, “Install the latest patch.” This was heard often in the wake of the WannaCry ransomware and the NotPetya wiperware. But how would a clinical engineer go about figuring out the underlying firmware and the patch version of an infusion pump, the operating system of a thermostat to determine whether a patch is needed, where to get the patch, or whether patching is even permitted by the manufacturers or regulators?
The initial challenge lies with manufacturers. Many smart devices use a modified version of Linux, which immediately brings tens of thousands of lines of code into the device. All complex software suffers from security vulnerabilities and Linux is no exception: 85 high-severity vulnerabilities in the Linux kernel were found during 2016 alone.
Added to this are vulnerabilities hiding within the software used to provide the IoT device’s functionality. These are harder to quantify as the code is usually proprietary, but without a doubt they are widespread: at DEFCON 2016, 47 new IoT security flaws were discovered in products from 21 separate manufacturers. Secure hardware architecture, secure coding standards, and comprehensive auditing are key to maintaining a strong level of security. The challenge for manufacturers is applying the right level of focus and having access to the required skills to address these needs.
Even if manufacturers do release security patches for their devices, they still can’t be connected to a centralized patch management solution. Manually patching IoT devices is a shadow IT task of epic proportions – if you can find them in the first place. MITRE is currently running a challenge with a $50,000 prize fund for solutions that detect and identify IoT devices.
During the internship we are proposing within Nokia, we will tackle this problem by deploying a Nokia in-house distributed patch management solution based on the blockchain technology.
Experience working on open-source, large projects;
Experience with programming languages such as Java,
Python and basic knowledge of NoSQL or MySQL;
Proven expertise and knowledge of Blockchain frameworks
and business applications, as well as cryptographic
protocols and crypto libraries;
Knowledge of symmetric and asymmetric cryptographic
principles, zero knowledge proof and multi-party
computation;
Deep understanding of Hyperledger, Ethereum or other
Blockchain community technical issues.
