By the end of this year there will be 5.8 billion Internet of Things (IoT) endpoints, according to Gartner. And depending on how IoT devices are counted the number is even higher. Statista, for example, estimates the device count for 2020 to be more than 30 billion. Security remains a big challenge for IoT as a strategy to be successful. IoT devices are still not being designed with security as a top priority.Mary O’Neill, VP of security at Nokia, noted in a press conference at MWC Los Angeles 2019 and reported by SDXCentral, that “if an IoT device today is plugged into the network and it doesn’t have protection on it, it’s infected in three minutes or less.”Jake Williams, founder of the security firm Rendition Infosec, said that “IoT vendors emphasize, often rightly, that their products improve quality of life, but they often neglect to disclose the risk of these devices to consumers. The onus of understanding how an IoT device might impact security should not be purely on the consumer. The vendor shares this responsibility.
To paraphrase a well-known saying, the journey to a complete smart city begins with a single building. No matter the size of the city, the extent of the technology or the most helpful use cases, a prospective smart city can integrate into — or branch off of — initiatives pushed forward by a smart building or campus. And when there is an increasing demand for these types of solutions, large corporations have the opportunity to improve corporate and social governance practices, as well as stand out in their community by championing more connected technologies.
IoT equipment designers shooting for efficiency should explore the potential for using buildings as antennas, researchers say. Environmental surfaces such as walls can be used to intercept and beam signals, which can increase reliability and data throughput for devices, according to MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL).Researchers at CSAIL have been working on a smart-surface repeating antenna array called RFocus. The antennas, which could be applied in sheets like wallpaper, are designed to be incorporated into office spaces and factories. Radios that broadcast signals could then become smaller and less power intensive.
To prevent counterfeit devices from joining a network or to limit the opportunity for network attacks, it’s important to authenticate devices attempting to join Internet of Things (IoT) networks and subsequently connect only authorized devices. The standard mechanism to securely authenticate clients connecting to a server is transport-layer-security (TLS) client-side authentication. To implement such authentication in an IoT network, the appropriate certificate authority (CA)—usually the IoT device provider—issues a unique X.509 certificate to each IoT device and the associated private key that functions as a unique security credential for the IoT device. Once the certificate and associated private key are stored on the IoT device, it may use them during the TLS client-authentication process to securely join the IoT network.
