Technology strategies are more important than ever. The changes we’re seeing now will persist long after the stay-at-home orders are lifted, so it’s vital that your tech can keep up with the changing times.
IT and ICS network communication is critical, but security dictates that there should be minimal access points between the two networks. By segmenting these networks, you substantially minimize vulnerabilities.
The use of DNS in an ICS network is rare; reject DNS requests outside of the ICS network, and host files on local machines. Use host files on local machines.
ICS networks are typically isolated and perform repetitive functions, therefore necessary FTP connections should be well known. FTP is a common data sieve. Avoid data FTP data loss by identifying and monitoring necessary FTP connections and use SFTP if possible.
Vendors rely on remote access to access for diagnostics, repairs, systems improvements and more. Employees and partners need remote access to the shop floor and the network. It’s important to know and track who has remote access permissions.
