How are you protecting your industrial control system from cyber security threats/attacks?

[AUVESY_MDT]

One of the easiest and successful ways to launch an attack in a manufacturing facility is to change an automation’s device program data. There are many products that claim to protect a facility from an attack and while many are useful, none can fully protect control logic from being changed inadvertently or maliciously. 

An integrated approach to cybersecurity is necessary for comprehensive protection and it must include the management of automated device programs and their changes. Read this Schneider Electric blog article for information on this topic and get recommendations on different ways to prepare, detect and recover from an attack on program data.

Modbus cable solved it.
