For security professionals and CISOs, reading about operational technology (OT) security risk feels like nothing new. We know a lot of OT is insecure by design. Despite advisory warnings and perceptions around operational security air gaps, industrial control systems (ICS) and Supervisory Control and Data Acquisition (SCADA) are being targeted more frequently via digital assets […]

By 2028, connected Internet of Things (IoT) devices will expand to over 25 billion. Yet, today’s connected devices are raising the stakes for assessing risk and managing cybersecurity. They have significantly expanded the attack surface creating new challenges and vulnerabilities. The need for accurate, rapid information from systems across every industry is essential for business operations. From […]

On May 9, the North American Electric Reliability Corporation (NERC) officially adopted new Critical Infrastructure Protection (CIP) requirements for Internal Network Security Monitoring (INSM). This is one of the last steps before Federal regulators make it an official standard for utilities and the electrical power grid industry. What does it mean? Compliance for  CIP-015-1 is […]

The security of embedded devices is in the news over the last few years, especially IoT assets and OT systems. From connected medical devices to industrial control systems to smartwatches and building automation, connected IoT devices will expand to over 25 billion by 2028. Critical infrastructure is under siege at 13 attacks per every second. The […]

Here is the story of how we caught a ransomware attack in our research honeypot. Ransomware attacks on enterprise organizations lead the news. See Change Healthcare and Ascension. Attackers spend their time on the victim’s network, exfiltrate gigabytes of sensitive data, then lock victim’s systems — and ask for millions of dollars in ransom payment. […]
