The oil and gas industry has high levels of cyber awareness and low levels of cyber insurance, says a sectoral assessment from credit rating agency Moody's. The sector has experienced a clutch of high-profile attacks including a high-profile 2021 incident at Colonial Pipeline.
Swiss utility giant Centralschweizerische Kraftwerke has transformed its legacy operational communication network with a hybrid multiservice platform. Yann Gosteli, head of secondary systems at CKW, shares how the company has built an operationally efficient network infrastructure.
As digital transformation continues to reshape industries, the convergence of operational technology and cybersecurity has emerged as a critical area of focus. But there's a noticeable gap in the workforce. Professionals who truly understand both OT and cybersecurity are in short supply.
Don't pull data from an operational technology network: OT networks should push data out. Segment critical OT networks. Don't introduce cybersecurity systems into an OT network unless administrators can guarantee they won't hinder a restart after a complete loss of electricity.
Dragos' acquisition of Network Perception will enrich its real-time network monitoring with robust visualization and configuration analysis tools. This transaction aims to bolster the security of operational technology networks and support customers in building more defensible architectures.
Industrial control systems made by different manufacturers for monitoring fuel storage tanks including those used in everyday gas stations contain critical zero-days that could convert them into targets for cyberattacks that cause physical damage.
A severe vulnerability in Rockwell Automation software used to configure programmable logic controllers could allow attackers to remotely execute malicious code. The vulnerability is rated 8.8 on the CVSS v4 scale. The U.S. Cybersecurity and Infrastructure Security Agency advised immediate patching.
A secure convergence of IT and OT requires an industrial layer to bridge these systems. This layer ensures safe operations by segmenting networks and isolating legacy OT systems, preventing exposure to attacks, said Baidyanath Kumar, CISO and DPO at JK Lakshmi Cement.
Preparing healthcare organizations to respond to and rebound from a disruptive ransomware attack is akin to implementing a "12-step program," said Dr. Eric Liederman, CEO of consultancy CyberSolutionsMD and recently retired long-serving director of medical informatics at Kaiser Permanente.
Excessive deployment of remote access tools in operational technology environments expands attack surfaces and creates operational challenges, warn security researchers from Claroty. Remote access tools are essential, but they introduce numerous potential vulnerabilities that threat actors exploit.
Critical infrastructure encompasses the essential services and assets vital to the functioning of society and the economy. Specializing in security in this field requires a deep understanding of the challenges and threats facing sectors such as energy, transportation, healthcare and water systems.
An artificial intelligence-fueled growth in data center construction has the federal government asking what it should do to help manage data security risks. The NTIA is interested in identifying opportunities "to improve data centers’ market development, supply chain resilience, and data security."
Centralized architecture in the automotive industry streamlines cybersecurity and supply chain operations by reducing hardware components and enabling quicker fixes. But that centralization also poses major cybersecurity challenges, said Thomas Sermpinis, technical director at Auxilium Pentest Labs.
The Cyber Security Agency of Singapore released an updated operational technology cybersecurity master plan to boost the OT cybersecurity workforce and enable critical infrastructure and other operators to prepare for emerging cybersecurity risks and build effective response plans.
Piotr Ciepiela, EMEIA cybersecurity leader at EY, discusses the challenges of securing OT systems and contrasts them with IT SOC environments. He emphasizes the need for specialized tools, dedicated personnel and strong collaboration with engineering teams to manage OT SOC operations.
