A communication system personality provisioning system includes a communication system included in a computing system and coupled to a management system. The communication system stores authentication information in a UEFI database of a UEFI system in the communication system. The communication system receives a first operating software image and application/service from the management system, authenticates the first operating software image and application/service via first secure initialization operations performed by the UEFI system using the authentication information and, in response, installs the first operating software image and application/service on the communication system. The communication system subsequently receives a second operating software image and application/service from the management system, authenticates the second operating software image and application/service via second secure initialization operations performed by the UEFI system using the authentication information and, in response, installs the second operating software image and application/service on the communication system.
