Brett Zupan, former WaterISAC analyst, penned an expository regarding the myriad of all-hazards threats, including physical, cyber, and blended, faced by members of peer organization, REN-ISAC (Research & Education Networking Information Sharing & Analysis Center). Zupan explains the spectrum of physical and cyber threats, including sophisticated, unsophisticated, and accidental, that conceivably could affect every critical infrastructure sector - some more than others - including Water and Wastewater. The post concludes with a compelling approach to pre-event threat awareness that includes greater cross sector collaboration for a more holistic threat management response. Gate 15.
