Like for Harry Potter, the best defense for your industrial systems against cyber enemies might be an invisibility cloak.
“If your site can’t be seen, it can’t be hacked,” says Xavier Mesrobian, vice president of sales and marketing forSkkynet Cloud Systems，成员控制System Integrators Association（CSIA）。该公司在1月份的安全云服务赢得了M2M Evolution Conference and Miami博览会上的最佳物联网安全解决方案的平台战役时，该公司的安全性工作得到了认可。
Mesrobian表示，尽管公司一直依靠虚拟专用网络（VPN）来确保其连接到Internet时的信息安全性，但这种方法具有致命的缺陷。它要求通过公司的防火墙端口始终保持访问和传输数据。这使黑客能够窃取身份验证代码和密码以访问网络上的任何设备。据报道，这是中国黑客最近在广泛攻击美国政府系统中使用的方法。
Skkynet说，它具有更好的方法，它称为“设计安全”，这是一个将数据推出防火墙的发布和订阅系统。它使用称为WebSocket的不同连接模型，该模型可以以一种仅允许从工厂到云的站点连接的方式应用于工业数据通信。
“No inbound connections are necessary; no plant firewall ports need to be left open,” Mesrobian says. “Once the connection is established, the data can flow in both directions. Or you can choose to make all or some of your data read-only, preventing any write back from the cloud.”
Mesrobian explains further, “A static IP address can always be made visible, but by using an approach that’s secure by design, it’s virtually impossible to break into a system. With no inbound ports, a company’s site can’t been seen by the Internet.”
Security is one concern as industrial technology advances and more machines and devices are connected to the Internet. Read the full article about thetransformation of machine-to-machine practices.
