In a separate report late last week, another hacker was able to access and then post diagrams of the South Houston sewer system online in an attempt to demonstrate the system's vulnerabilities. DHS officials are investigating both incidents and have confirmed that there is currently no identified risk to critical infrastructure entities or a threat to public safety.
These incidents highlight the ongoing debate about the security of our nation's water utilities. As previously discussed, water utilities are currently statutorily exempt from the Chemical Facility Anti-Terrorism Standards (CFATS) program - even though many often may possess significant quantities of Chlorine - one of the so called Chemicals of Interest that could bring a facility under CFATS regulation.
Many believe that Congress should remove the statutory exemption - and require water utilities to comply with CFATS' security mandates. One of those mandates, Risk-Based Performance Standard (RBPS) 8 (Cyber), requires facilities to "[d]eter cyber sabotage, including preventing unauthorized on-site or remote access to critical process controls, such as Supervisory Control and Data Acquisition (SCADA) systems...." Mandating such measures at water utilities would certainly prevent or at least mitigate these types of attacks.
Whether or not Congress acts to remove the exemption in 2012 is unknown but I will follow the issue closely and keep you posted.
