INFORMATION PROCESSING APPARATUS
First Claim
1. An information processing apparatus having a first network interface, which is capable of communicating with other information processing apparatus via the first network interface, comprising:
- a second network interface for performing communication with other information processing apparatus in place of the first network interface, whereinswitching processing for switching a network interface to be operated from the first network interface to the second network interface is executed when an unauthorized access from outside is detected, and at time of the switching processing, internal information of the information processing apparatus is saved in the second network interface.

Abstract
Provided is an information processing apparatus capable of protecting against an unauthorized access from outside without increasing load of packet analysis and also capable of performing protection from a device inside a network. The information processing apparatus has a first network interface (illustrated using an NIC as an example) and is communicable with other information processing apparatus via the NIC. The information processing apparatus further has a second network interface (illustrated using an energy saving NIC as an example) for performing communication with other information processing apparatus in place of the NIC. The information processing apparatus executes switching processing for switching a network interface to be operated from the NIC to the energy saving NIC when an unauthorized access from outside is detected. At the time of the switching processing, internal information of the information processing apparatus is saved in the energy saving NIC.
