It has been proven in a number of scenarios that air-gapped networks can be infiltrated. In theory, air-gapped networks seem like a great idea. Is Air-gapping Effective or a False Sense of Security? Now that more and more field devices are “smart” (connected to and managed through the network), is air-gapping a reliable cybersecurity strategy for the future? In today’s Industry 4.0 revolution, where the network is the control system, analyzing data from the industrial process is key to driving optimization and efficiency. In the industrial world, these air-gapped networks have traditionally supported the industrial control systems within the plant or factory, where communication was physically or logically isolated from the corporate enterprise networks. Because of such threats, many organizations choose to have air-gapped networks. Think of all the damage an attack could cause: loss of productivity, loss of assets such as data, plant shutdown and worse. The simple answer is that isolation implies security.īy the end of 2019, it has been estimated that every 14 seconds a business will fall victim to a ransomware attack. Over the years, networks in a variety of verticals, including government, military, financial services, nuclear power plants and industrial manufacturing, have been so-called “air-gapped.” This deserted island example illustrates what it means to be a part of an air-gapped network – physically isolated with no access to the outside world. Similarly, information from other islands or from around the world will never reach the island – there is simply no physical way for information to get in or out. You have conversations and share information with each other, but those conversations can never be shared outside the group on the island. Think of it this way: You and a few friends are on a deserted island.
