Article by Leon Poggioli, ANZ Regional Director at Claroty Traditional manufacturing plants and OT (Operational Technology) networks had no internet connectivity. They could run in a semi-isolated fashion, and there was little risk of a cyberattack. As the modern OT network becomes more digitised and technology-enabled to leverage AI and increased automation, they are now experiencing a much higher level of cyber risk. Traditional plants were operated very much onsite, with access controlled by strong physical mechanisms like site inductions and physical security methods permitting people to attend the site, make changes and operate the facility. The digital transformation now underway in OT networks has resulted in far more digital connectivity, with a greater focus on safety and productivity meaning more work is completed via digital methods – either by operators onsite, remote workers and 3rd party contractors, or remote machine-to-machine connectivity, with things like cloud-based AI analytics which optimise plant infrastructure. Traditional methods of access to these networks have not kept up with the digital transformation underway in OT. Password-sharing continues as a common practice, and many devices remain configured with default credentials. One recent example where this occurred was the cyberattack on Unitronics devices used by Water Authorities in the United States, which were directly exposed to the internet with default credentials configured. Some more mature organisations use a complex web of jump-boxes and VPNs to broker access to key systems in a zoned OT network, making it difficult to administer and maintain strict zero trust access to critical systems, not to mention the impact to useability as users need to log in via multiple hops to perform the work they need to perform. The digital transformation underway in cyber-physical networks demands a better approach to broker access securely to critical production systems, without compromising useability or adding unnecessary complexity.  Users […]

Aramid textile-coated reusable Pronal CLT lifting cushions in capacities up to 65 tons per unit Mining, construction, energy exploration, and infrastructure groups are becoming ever nimbler in moving plant, people, and resources over major distances as opportunities decline at one site and open up in more profitable areas. This has led to a new generation of transportable technologies and plant, including portable buildings and transportable facilities that need to be safely lifted for trucking to new destinations. “Such vital facilities can include accommodation, maintenance, engineering, testing, and medical facilities, extending through to containerised energy management and electronic technologies associated with electrification and automation of sites,” says Pronal elastomer engineering specialist Vinh Lam, of Pronal exclusive Australian national distributor Air Springs Supply Pty Ltd. A problem associated with such lift and shifts is creating access gaps under loads for safe lifts onto transport, particularly where space around the load may be limited, or site conditions may involve soft or variable substrates that preclude the initial use of  hydraulic or mechanical lifts with high point loads. Even on hard surfaces, using crane or forklifting techniques to create the initial lifting gap may damage hard concrete or tarmac surfaces, unless a working gap is first created for optimally safe access beneath heavy structures, or structures that may have been in place for some time. Pronal lifting cushions gently and safely lift multiple structures and fixed and mobile plant, including containerised plant. “Heavy processing equipment and portable structures often need to be raised to a low height to enable safe clear access so forklift tynes, crane strops, or standard lifting equipment or vehicles can do their work of loading onto transport,” says Vinh Lam. “The lifting gap is important, because it enables heavy lifting equipment to get through beneath the base of the load […]
