Through content control gateway (CCG), computer communicates to inner network server (INS). CCG is setup in front of INS. Computer inside inner network includes working software of 'security desktop'. Encrypted tunnel is adopted between computer and CCG. Cipher mode is used for local computer to save files. Cipher key is setup at local computer. Based on working software of 'security desktop', working system uses cipher mode to save files in local computer, and carry out network transmission. When trying to access INS, terminal computer must log on CCG first. Based on authorization of terminal and condition to activate 'security desktop', CCG determines whether to execute accessing proxy. If 'security desktop' is not activated, then access from the terminal is refused, or 'security desktop' is forced to be turned to on to continue accessing. Through 'security desktop', terminal can only access CCG, and cannot access other network addresses.
