Defense Support for Cyber Emergencies Response Act

This bill allows the Secretary of Defense to order Selected Reserve and Individual Ready Reserve members to active duty for up to 365 days without their consent to respond to significant cyber incidents affecting national security. It directly affects military reservists by enabling their deployment during cyber emergencies involving Department of Defense systems or incidents declared by the President. The key provision defines "covered incident" as cyber events causing demonstrable harm to national security, the economy, public confidence, or public health/safety. This creates a new mechanism for rapidly deploying reserve forces to support active military responses to cyber threats.
