In an interview with risk management firm Gate 15, WaterISAC Managing Director Michael Arceneaux discusses security issues, priorities, and efforts for the water and wastewater sector. The interview begins with a discussion of the sector being a critical lifeline sector, meaning that its compromise would put human health and economic security at risk if it were not restored quickly. As Michael explains, the criticality of the sector is not universally understood, necessitating efforts by sector leadership, WaterISAC, and other sector advocates and organizations to continuously engage with partners in government, other sectors, and the public at large to push for its prioritization in decisions related to homeland security. Michael also addresses some of the security concerns facing the sector and what WaterISAC is doing to confront them. Among these are cyber threats, which WaterISAC works to protect the sector against by facilitating information sharing among utilities, including via automated solutions that make the task much more efficient and effective than in the past.
