UL SETS NEW STANDARD FOR CYBER SECURITY
Managing the cybersecurity of industrial plants and infrastructure has never been more challenging. Targeted attacks by nation states and cyber-criminals are on the rise. Sophisticated attack methods
and malware are overcoming perimeter defences, giving attackers wide access to controllers and sensors. Plants cannot trust that their
ABOUT PITOTS Three Pitot-statics from two
different commercial aircraft were X-rayed by a CT scanner and an acoustic study was carried out to find out the variation between blocked and unblocked reflected acoustic waves. Experiments using a range of blockage types, including tape, insects, foam and metal, were also conducted on the same tubes. The research found it is
possible to detect blockages reliably, even for particularly small tubes, and for tubes containing non-cylindrical shapes. However, for the method to work well, it is necessary for there to be a simple tube along most of
the length of the pressure duct. “In principle, the method could
be adopted to help inform pilots if Pitots are blocked before they take off, or if they subsequently become blocked during a flight,” said Thomas Rendall, Senior Lecturer in the Department of Aerospace Engineering at the University of Bristol. “Our results are encouraging
for a ground-operable system, but the effect of the background noise field in flight needs to be established before a flight- operable system could be implemented. The system would also need to be made smaller to fit into the tight confines of an aircraft structure.”
safety systems are protected from cyber-attacks. Companies need to take proactive precautions to mitigate cyber risk within industrial control systems. Being prepared can limit the likelihood of an attack by identifying and addressing vulnerabilities before they can be exploited. The Industrial Internet of
Things (IIoT) adds fuel to this fire. Companies are deploying new devices throughout their plants to improve asset maintenance and optimise operational performance. However, any malware or
flawed security mechanisms that may be present in these devices represents a potential threat to plant security. Connecting devices to cloud- based analytics programs opens additional pathways for external attacks. Companies need to take steps
to secure IIoT devices from latent malware and use robust
security controls that align with industry best practices. Recently, industry marketing
company the ARC Advisory Group discussed these challenges with executives from UL, the well-known global safety science organisation that provides advisory, testing, and certification services. UL, which has been active in
industry for more than 120 years, recently published the UL 2900 Series of Standards that offers testable cyber security criteria for IIoT devices. These incorporate guidelines from a variety of well-known standards. UL 2900-2-2, specifically designed for industrial control systems, aligns with IEC 62443 criteria. Experts from UL have
developed the UL 2900 standard with input from major government, academic, and industrial organisations. Their goal was to create a standard with broad-based coverage of security issues and support for many different industrial sectors. A key challenge was to
ensure that it reflected the requirements of many different industrial cyber security standards and guidance documents in use today. For example, UL 2900-2-2 applies some security criteria from IEC 62443 for product testing and process validation.

commands in Release 3.7 are designed for non-destructive detection of hidden flaws in plastics or openings in foam. Active and passive thermal imaging can be conducted, and even surface shapes of transparent materials, such as in
adhesive beads, can be inspected. Early application areas are the automotive and aircraft industries. Gas turbines are exposed to
enormous temperatures and centrifugal forces so the demands on the quality of each component is high. Inspection involves the complete manufacturing chain, from the cast of the blades to applying the thermal barrier layer.
