(AP) — President Joe Biden signed an executive order Wednesday meant to strengthen U.S. cybersecurity defenses in response to a series of headline-grabbing hacking incidents that highlight how vulnerable the country's public and private sectors are to high-tech spies and criminals operating from half a world away. > The order will require all federal agencies to use basic cybersecurity measures, like multi-factor authentication, and require new security standards for software makers that contract with the federal government. Officials are hoping to leverage the federal government's massive spending power to improve security across all types of software.
