Issue
A Programmable Logic Controller (PLC) is an industrial computer that is adapted for the control of manufacturing processes. Given the central role that it plays, it has been a preferred target of industrial control system attackers. ICS (or Industrial Control System) security is growing in importance as cyber-attacks increasingly focus on physical processes for either ransom or to cause harm to critical production systems.
The main objective of cybersecurity is to protect information and physical assets from cyberattacks, data breaches, and identity theft, as well as to manage risks.
This document aims to guide you on how to set up and configure a secure connection between EcoStruxure Control Expert and the Modicon M580 controller.
Resolution
The Modicon M580 controller uses HTTPS as its secure connection.
HTTPS today uses Transport Layer Security or TLS. TLS is a network protocol that establishes an encrypted connection to an authenticated peer over an untrusted network. TLS is a direct replacement for SSL (Secure Sockets Layer), and both protocols serve the same purpose. With this technology, HTTPS or HTTPS via USB communication on the M580 CPU can be implemented to create a secure and encrypted connection via the engineering/programming link.
