  • Patent number: 11863662
    Abstract: A system validates the establishment and/or continuation of a connection between two applications over a network. The system uses network application security rules to allow or disallow connections between the two applications. Those rules include definitions of the source and destination applications to which the rules apply. The system automatically updates the application definitions over time to encompass new versions of the applications covered by the security rules, but without encompassing other applications. The system is then capable of applying the updated rules both to the original applications and to the updated versions of those applications. This process enables the security rules to maintain security over time in a way that is consistent with the original intent of the rules even as applications on the network evolve.
