Abstract
Today’s industrial automation systems are undergoing a digital
transformation that implies a shift towards the Internet of Things
(IoT), leading to the Industrial Internet of Things (IIoT) paradigm.
Existing Industrial Automated Control Systems (IACS), enriched
with a potentially large number of IoT devices are expected to make
systems more efficient, flexible, provide intelligence, and ultimately
enable autonomous control. In general, the majority of such systems
come with high level of criticality that calls for well-established
methods and approaches when achieving cybersecurity, preferably
prescribed by a standard.
IEC 62443 is an industrial standard that provides procedures
to manage risks related to cybersecurity threats in IACS. Given
the new IIoT paradigm, it is likely that existing standards are not
sufficiently aligned with the challenges related to developing and
maintaining cybersecurity in such systems. In this paper we review
the applicability of the IEC 62443 standard in IIoT contexts and
discuss potential challenges the process owners might encounter.
Our analysis underlines that some areas within the standard
could prove difficult to reach compliance with. In particular, handling
of cross zone communication and software updates require
additional guidance.
