What Every CISO Should Ask about OT/ICS Security

It is not uncommon for OT/ICS cybersecurity to fall under the authority of IT. This isn’t necessarily a bad thing, unless IT is taking responsibility/action and lacks OT-specific knowledge. While many concepts can be drawn from IT security to help secure OT, many of the processes do not translate well. The opposite also presents a challenge, as many OT operators and engineers may not have cybersecurity experience. This is why it is imperative for both OT and IT cybersecurity teams to work together; however, that isn’t always as easy as it sounds.

NCI Ransomware Report: Analysis of Activity and Recommendations to Disrupt Operations

The National Council of ISACs (NCI), of which WaterISAC is a member, has published a report describing how criminal organizations conduct ransomware operations and their impact to society. The report provides a thorough background of ransomware, to include providing descriptions of how ransomware infections occur and offering key statistics. One of these statistics is an estimate from the FBI that there are 4,000 ransomware attacks every day, equating to a ransomware attack every 40 seconds.
