1. A method for automatically managing a platform firewall using a network function (NF) repository function (NRF) or service communication proxy (SCP), the method comprising:
at an NRF or SCP implemented by at least one processor:
receiving a message relating to registering, updating, or deregistering an NF profile in an NF profiles database separate from a platform firewall, wherein receiving a message relating to registering, updating, or deregistering the NF profile includes receiving an NFRegister request or response relating to registering the NF profile with the NRF;
determining that the registering, updating, or deregistering of the NF profile requires a change to a firewall rules configuration of the platform firewall; and
in response to determining that the registering, updating, or deregistering of the NF profile requires a change to the firewall rules configuration of the platform firewall, automatically updating, by the NRF or SCP, the firewall rules configuration of the platform firewall, wherein automatically updating the configuration of the platform firewall includes adding a rule to the platform firewall rules configuration to filter packet traffic to or from the NF.
