Digitised systems, while more efficient, are not without their concerns. A cyber security expert outlines the various digital threats that enterprises are vulnerable to and suggests some counter measures to prevent these security risks. Industry 4.0 is a standard term to depict the fourth-generation industrial revolution that we are passing through nowadays. Automation, IoT and data analytics have made production processes smarter, intelligent and more productive. With each passing day, latest technologies like cloud computing, IoT and robotics are disrupting the traditional manufacturing process as we know them. This transitional shift to digitisation and automation is what everyone is calling the 'Industry 4.0' era. IoT, being one of the most important aspects of cyber security Industry 4.0 for India, is expected to capture more than 22 per cent share in the global IoT market in the coming few years. Cyber security experts all over the world are concerned about the implications of Industry 4.0. Digitally connected industries are more vulnerable to attackers who are looking to exploit resources and data. The lack of effective cyber security measures within IoT-enabled production environments is posing a serious threat to the future of cyber security in the world and India.
