system be totally secure

Suppose you are provided with several computer systems on the market. The systems include hardware, system software, applications, operating systems, DBMS and many others. Is it possible to enhance one of the computer systems such that it can be customized to be a totally standalone system, so much so that the system only processes and outputs the required results, no other external inputs and no upgrade of the system are required. Will this system be totally secure? Discuss from all possible perspectives. Your aim is to derive a 100% safe system. You must state all possible assumptions, constraints, etc.
