Measuring cybersecurity: The what, why, and how

A core pillar of a mature cyber risk program is the ability to measure, analyze, and report cybersecurity threats and performance. That said, measuring cybersecurity is not easy. On one hand business leaders struggle to understand information risk (because they usually are from a non-cyber background), while on the other, security practitioners get caught up in too much technical detail which ends up confusing, misinforming, or misleading stakeholders. In an ideal scenario, security practitioners must…

PLC vulnerabilities can enable deep lateral movement inside OT networks

Threat groups who target operational technology (OT) networks have so far focused their efforts on defeating segmentation layers to reach field controllers such as programmable logic controllers (PLCs) and alter the programs (ladder logic) running on them. However, researchers warn that these controllers should themselves be treated as perimeter devices and flaws in their firmware could enable deep lateral movement through the point-to-point and other non-routable connections they maintain to other low-level devices. To exemplify…

Plan now to avoid a communications failure after a cyberattack

Responses to recent cyber breaches suggest organizations can struggle to get the message right in the midst of an incident. While managing the communications around an incident is outside the direct purview of the CISO, having an existing communications plan in place is an essential element of cyber preparedness. “Communications are a critical component of a good cyber strategy, and it should be prepared and practiced in organizations before an incident occurs,” says Eden Winokur,…

Flaws in industrial wireless IoT solutions can give attackers deep access into OT networks

It’s common for operational technology (OT) teams to connect industrial control systems (ICS) to remote control and monitoring centers via wireless and cellular solutions that sometimes come with vendor-run, cloud-based management interfaces. These connectivity solutions, also referred to as industrial wireless IoT devices, increase the attack surface of OT networks and can provide remote attackers with a shortcut into previously segmented network segments that contain critical controllers. Industrial cybersecurity firm Otorio released a report this…
