Over the past few years, the Internet of Things (IoT) has become increasingly ubiquitous. Over 27 billion networked devices will be online in 2021 and 75 billion by 2025. The Industrial Internet of Things (IIoT), in particular ,could add $14 trillion to the global economy by 2030. Numerous industry sectors already rely on IIoT devices like smart meters, alarms and sensors for business-critical tasks like machine automation, monitoring and predictive maintenance; inventory tracking; and process/workflow transformation.
how you can become a virtual assistant, and how you can get the most out of a career as a virtual assistant?
But despite its growing prominence, organizations moving to IIoT cannot afford to ignore its security issues. An IIoT network can extend over many miles and have hundreds of thousands of data points. A weakness in one device can make all other devices on the network vulnerable to cyberattacks, and increase the risk of process interruptions, unauthorized manipulation and even corporate espionage.
To protect IIoT devices and networks, companies must stop thinking of security as an afterthought. Security by obscurity is not an adequate solution; the need of the hour is security by design.
