The Cybersecurity Information Sharing Act (CISA) of 2015 is set to expire at the end of this month on September 30, 2025. The Act removes barriers to companies sharing information about cyber threats, addressing privacy concerns and requires the federal government to share threat information. Many consider CISA one of the foundations of U.S. cybersecurity efforts.   As Congress considers whether or not to reauthorize CISA, former Deputy Assistant Director of the FBI cyber division, Cynthia Kaiser, joins David Aaron to discuss the importance of the legislation and highlight the risks of failing to reauthorize it. Show Note: “The Next Cyber Breach Will Not Wait: Why Congress Must Reauthorize CISA 2015” by Simin Kargar for Just Security  Just Security’s CISA coverage Just Security's Cybersecurity coverage

Last week, the United States carried out an unprecedented strike against a vessel suspected of narcotics trafficking in the Caribbean, destroying the vessel and reportedly killing 11 people on board. This action raises highly concerning questions about the process followed within the U.S. government: how and by whom was the strike authorized?  Why was it carried out by U.S. armed forces? And what kind of accountability or pushback might we see from Congress, in courts, or within the government itself?Rebecca Ingber and Brian Finucane join Tess Bridgeman to unpack the attack, the limited justifications the administration has put forward to date, and what to expect from here. Show Notes: Legal Issues Raised by Lethal U.S. Military Attack in the Caribbean by Brian FinucaneLabels, Not Law, to Justify Lethal Force: Venezuela Boat Strike by Mark Nevitt
