Addressing growing concerns about cybersecurity in manufacturing

Posted on by

Manufacturing has become increasingly reliant on modern technology, including industrial control systems (ICS), Internet of Things (IoT) devices and operational technology (OT). While these innovations boost productivity and streamline operations, they’ve vastly expanded the cyberattack surface. According to the 2024 IBM Cost of a Data Breach report, the average total cost of a data breach in […]

The UK energy sector faces an expanding OT threat landscape

Posted on by

Critical infrastructure is under attack in almost every country, but especially in the United Kingdom. The UK was the most attacked country in Europe, which is already the region most impacted by cyber incidents. The energy industry is taking the brunt of those cyberattacks, according to IBM’s X-Force Threat Intelligence Index 2024. The energy sector […]

Why Operational Technology Security Cannot Be Avoided

Posted on by

Operational technology (OT) includes any hardware and software that directly monitors and controls industrial equipment and all its assets, processes and events to detect or initiate a change. Yet despite occupying a critical role in a large number of essential industries, OT security is also uniquely vulnerable to attack. From power grids to nuclear plants, […]

X-Force 2022 Insights: An Expanding OT Threat Landscape

Posted on by

This post was written with contributions from Dave McMillen. So far 2022 has seen international cyber security agencies issuing multiple alerts about malicious Russian cyber operations and potential attacks on critical infrastructure, the discovery of two new OT-specific pieces of malware, Industroyer2 and InController/PipeDream, and the disclosure of many operational technology (OT) vulnerabilities. The OT cyber threat landscape […]

Where Everything Old is New Again: Operational Technology and Ghost of Malware Past

Posted on by

This post was written with contributions from IBM Security’s Sameer Koranne and Elias Andre Carabaguiaz Gonzalez. Operational technology (OT) — the networks that control industrial control system processes — face a more complex challenge than their IT counterparts when it comes to updating operating systems and software to avoid known vulnerabilities. In some cases, implementation […]

IoT Security: Protecting Food and Agriculture Organizations

Posted on by

Ransomware actors are targeting food and agriculture organizations, potentially disrupting business. Luckily, there are already formal structures in place to boost the IoT security defenses they need. Knowing them keeps the lifeblood of industrial farms and food delivery going. Businesses in the sector could “suffer significant financial loss,” the FBI said. That loss is “resulting […]
