These threats out-pace traditional Indicators of Compromise (IoCs) that were once a core tenant of information sharing strategy. With the CISA 2015 temporarily lapsing, this moment spotlights the ways in which the U.S. must rethink its cyber intelligence strategy - moving from reactive, infrastructure-based signals to proactive, behavior-driven insights that enable organizations to anticipate and disrupt attacks before they materialize.
Barring a last-minute deal, the US federal government would shut down on Wednesday, October 1, and the 2015 Cybersecurity Information Sharing Act would lapse at the same time, threatening what many consider a critical plank of US cybersecurity policy. The CISA Act of 2015 (not to be confused with the CISA Act of 2018, which established the government agency of the same name; the CISA referred to throughout this story is the Information Sharing law, not the agency) is due to expire 12:01 am ET on October 1, the same moment federal funding lapses absent a continuing resolution.
