The National Infrastructure Advisory Council is calling for drastic changes to increase the resiliency of U.S. water systems.

Attacks against critical infrastructure are reaching new heights, but strategy documents outlining federal efforts are a decade old.

The Environmental Protection Agency's water cybersecurity standards follow the Biden administration's new national cyber strategy.

The water sector is seen as among the nation's most vulnerable critical infrastructure to cyberattack after attacks in Florida and California.

There are about 52,000 drinking water systems in the U.S. and that fragmentation makes the sector harder to defend, experts say.

Previously, the Biden administration pushed the initiative in the electricity sector and for pipelines.

The big-ticket cyber item in the Infrastructure Investment and Jobs Act is $1 billion in state and local grants.

Broadly, the administration is also formulating a national cybersecurity strategy and looking at more regulations.
