While the benefits of Industry 4.0 are aplenty, the risks cannot be ignored. There are practices one can take to minimise such risks. This article takes a look at some such solutions
With recent advances in manufacturing such as automation, remote manufacturing and control concepts, we are entering the age of Industry 4.0. While the benefits are immense, this also poses certain risks. For example, if a factory is connected to an offsite data centre through a public or private cloud, network security is a concern. A connected factory exposes machinery to the risk of unwanted access, which could lead to machines getting corrupted. At the same time, it impacts production, thereby directly compromising company revenue.
There are some common practices one can use to minimise such risks. First, irrespective of a wired, wireless or combination solution, it is essential to ensure that the chosen connectivity technology has standard protocols (such as Wi-Fi, Bluetooth and the like). Also, while the industrial segment traditionally prefers proprietary solutions, it makes sense to use standard practices since these run a lower risk of being compromised.
One of the biggest challenges in maintaining security of remote factories is the skill-gap among embedded engineers. Most embedded engineers tend to be unfamiliar with cloud infrastructure and IT security concepts. Therefore they often struggle to create robust and secure Internet of Things (IoT) infrastructures without the support of IT experts.
Even a single weak link exposes the entire system to hackers, who typically seek just a single point of entry to obtain remote access to a large number of systems. There are several recent examples of largescale damage caused by distributed denial of service (DDoS) attacks. Since the weakest link in an IoT network is generally the hardware, lack of IT knowledge among hardware engineers becomes even more problematic.
