Israel's water system came under major attacks last year by what foreign intelligence sources described as an attempt by Iran to disrupt the country's critical infrastructure.

The attacks apparently sought to raise the level of chlorine in the water supply by changing the logic of the Programmable Logic Controller without raising any alarms.
In response, the Israel Water Authority decided to strengthen the cyber defenses of the country's water system. On Wednesday, the water authority announced that it had selected Israel's SIGA OT Solutions and its SigaGuard system to counter cyberthreats to the machinery and equipment that comprise the critical infrastructure which operates in the Industrial Control Systems (ICS) and Operational Technologies (OT) environments.
SigaGuard is also expected to handle ransomware attacks on critical infrastructure.
Amir Samoiloff, co-founder and CEO of SIGA, said, "Water utilities are at the forefront of global cyberattacks. But utilities have minimal tolerance for a downtime in service and no utility would agree to a hacker deciding whether its infrastructure will operate or not. The hacker's actual attack surface on water utilities is limited, and SIGA has the most suitable solution to deal with this threat, from both the cyber capability and operational standpoint."
