When not secured, HMIs can become vulnerable points of entry for bad actors, potentially leading to unauthorized access and disruptions in operations. This poses significant risks to employee productivity, data integrity, and worker safety.
An HMI is a technology or system that serves as the point of interaction between humans and machines, enabling users to monitor, control, and communicate with industrial equipment or processes in a more intuitive and user-friendly manner. HMIs grant access to production systems and sensitive production data, which is why safeguarding HMIs from unauthorized access, cyberthreats, and potential disruptions is paramount.
