Accelerating IACS/OT Cybersecurity Improvements

Don C. Weber
Risk managers—especially C-suite and boards of directors—looking to establish a culture of OT cyber awareness and risk remediation proactivity in their organizations need to establish a formal and measurable program approach. The program must provide a shared vision and a practical roadmap that makes sense because it relates to many of the unique characteristics of their organization, OT environment, business model, and risk appetite.

Water, Wastewater Cybersecurity Still Has Long Way to Go

George V. Hulme
Securing connectivity in operational technology (OT) environments is crucial for the safety of critical infrastructure and maintaining the uninterrupted service it provides. Leaving unnecessary open ports, protocols, and services exposed, along with directly connected devices to the internet, such as programmable logic controllers (PLCs) and human machine interfaces (HMIs), greatly increases the risks of cyberattacks.

CPS Security Leaders Convene on One Goal: Protect Mission-Critical Infrastructure

Upa Campbell
In OT and ICS cybersecurity, living off the land (LOTL) techniques refer to the practice of attackers using the existing tools and processes in a target system to carry out their malicious activities. This approach is particularly dangerous because it allows the attacker to blend in with everyday activities, making detection significantly more challenging.
