WASHINGTON (CBS19 NEWS) -- President Joe Biden has signed a National Security Memorandum to improve the cybersecurity of National Security, Department of Defense, and Intelligence Community Systems, as required in Executive Order (E.O) 14028, Improving the Nation’s Cybersecurity.

Senator Mark Warner, D-Va., who is chair of the Senate Select Committee on Intelligence and co-chair of the Senate Cybersecurity Caucus, released the following statement on Wednesday:

“I applaud President Biden for signing this order to improve our nation’s cybersecurity. Among other priorities, this National Security Memorandum (NSM) requires federal agencies to report efforts to breach their systems by cyber criminals and state-sponsored hackers. Now it’s time for Congress to act by passing our bipartisan legislation that would require critical infrastructure owners and operators to report such cyber intrusions within 72 hours.”
