May 2021 Technical Meeting

May 18 @ 7:00 pm - 8:00 pm

In early February of this year a water treatment facility was compromised in Florida. The attackers successfully increased the concentration of sodium hydroxide (also known as lye) by a factor of 100 risking potential illness for the public as well as significant erosion and pipe damage. Fortunately, operators of the Oldsmar water treatment facility saw the attackers increase the concentration and were able to return the concentration to normal levels before there was any risk for harm to the public. This near-miss highlights several important trends for industrial cybersecurity: Industrial cybersecurity incidents can have major health and safety implications, Critical infrastructure makes an attractive target to a variety of hackers, Critical infrastructure is highly susceptible to cybersecurity attack. In this webinar we will review what is known so far about the attack on the Florida water system and identify practical steps that can be taken to improve the cybersecurity of critical infrastructure systems.
