A system for verifying a software platform of a vehicle including at least one electronic control unit receives a first final confirmation value corresponding to a hash value of software measured in the electronic control unit from an integrated security apparatus inside the vehicle and extends a hash value of normally operated software received from a software manufacturer of the electronic control unit to generate a second final confirmation value. Next, the system verifies the software platform of the vehicle based on results obtained by comparing the first final confirmation value with the second final confirmation value.
