In a security level control apparatus for controlling a security level of a communication established between communication parties, this security level control apparatus is arranged by employing a security level recognizing unit and a security level setting unit. The security level recognizing unit recognizes a security level notified from a communication party. The security level setting unit sets the security level recognized by the security level recognizing unit as a security level for the security level control apparatus. In accordance with this security level control apparatus, the security level of the communication party recognized by the security level recognizing unit is first set as the security level for the security level control apparatus. As a result, the communication can be established between the communication parties without presetting the security level.
