Distribution of a certificate and a private key via a network includes a certificate/private key storage unit by which a certificate and a private key prepared for distribution to one or more devices are stored; a security level storage unit by which a security level for each device belonging to a device group is stored; and a display/instruction unit by which a selection screen prompting a user to select one or more devices from the device group is displayed. An instruction for the selection made by the user is received; and a certificate/private key distribution unit by which, via the network, the certificate and the private key for each device are distributed to the one or multiple devices for which the instruction for selection was made. For each device, the selection screen displays the device security level.

Certificate distribution device and method for same, and computer program

A network management/apparatus connected to a plurality of packet relay apparatuses constituting a group through a network includes an energy saving level calculation unit for calculating an energy saving level of each of the packet relay apparatuses on the basis of a CPU usage ratio of the packet relay apparatus managed or a difference between the present energy saving level and the energy saving level of minimum guarantee of the packet relay apparatus, and an energy saving function setting unit for setting an energy saving function of the packet relay apparatuses on the basis of the energy saving level calculated by the energy saving level calculation unit.

Network management apparatus

A serverincludes a scenario table in which object to-be-monitored information that indicates one or more network devices A, B and C being objects for failure recovery, failure information for identifying contents of failures, countermeasure information against failures, and frequency information that indicates the number of times of the recoveries from the failures based on the countermeasure information are correspondingly stored. The network device Adetects the failure of the network device itself and transmits a failure event to the server. The serverselects the countermeasure information item in descending order of the frequency information items, by reference to the scenario table, and transmits the selected countermeasure information item to the network device A. The serverrepeats the selections and transmissions of the pertinent information item until the reception of the failure event from the network device Astops.
