“…A Virtual Automation Network (VAN) [15][16] is a heterogeneous network consisting of wired and wireless For safety critical communication on PROFINET IO, IEC provides a safety profile, PROFIsafe [17]. This profile is based on the Black Channel concept from train communication [18], where the transmission systems do not have to be part of the functional safety certification.…”

In this paper we show that it is possible to attack and gain control over PROFINET IO nodes and also that this can be done without any of the communicating peers detecting the attack. Analysis of attacks in both shared and packet switched networks show that the attacker can control the process data and thus the state of the machines connected to the I/O modules.As the security risks are increasing in automation with the level of vertical and horizontal integration, the concept of security modules is proposed towards a method to retrofit security in PROFINET IO. The concept of security modules can be applied without changing anything in the underlying transmission system and is extendable if and when new security threats are identified.

“…To protect the backbone network traffic, established schemes from the IT world can be applied. However, these approved and common security mechanisms cannot be trivially mapped to the control level [3] due to resource limitations (e.g., network bandwidth, node processing power and memory).…”
