The National Security Agency (NSA) and Microsoft are advocating for the Zero Trust security model. The model grants access to data, apps, infrastructure, and networks after verifying and authenticating identities and checking that the devices are safe. Google implemented zero-trust security concepts following Operation Aurora in 2009 for an internal project that became BeyondCorp. The NSA gives three examples based on real cybersecurity incidents where the threat actor would have been unsuccessful if the concept had been implemented in the U.S. government networks.
