I have worked in MOXA more than 14 years. I am not only resposible to develop security-related fucntionalities on router products, but also assist cutomers to troubleshoot or customize product spec. for years. The projects that I have ever joint are about application on industrial, traspotation, power, oil&gas, and so on. Recently, I earn a pesonal certificate of IAS/IEC 62443 export. I am applying 63443-4-2 to our products and for now they are under the process of certification MOXA router products with IEC 62443-4-2.
