Secure Wireless Networking
While licensed-band radio systems and microwave links have been used for many years in SCADA applications, the use of wireless communications in ICS environments has increased significantly in recent years. It is more common to find WiFi and cellular access points in ICS networks, and some automation vendors are adding wireless functionality directly into their ICS products.
Wireless access to the ICS network introduces risks similar to ICS Remote Access with some additional threat vectors.Since the risk varies with the application, the decision whether to allow remote access to an ICS should always be based on the results of an ICS Cybersecurity Risk Assessment.
aeSolutions can assist by evaluating your current ICS wireless implementation and assisting in the design/redesign of a solution with the appropriate layers of security.
