US Patent 10089099 Automatic software upgrade

Systems, methods, and computer-readable media are provided for automatically downloading and launching a new version of software package on components in a network environment. In some examples, an upgrade server of a network environment keeps a copy of all versions of software packages running on nodes or sensors of the network environment, identifications of corresponding nodes or sensors, and public keys associated with the software packages. The upgrade server can authenticate a new version of a software package using a two-step process.
