20100241744 | Network Monitoring Apparatus and Network Monitoring Method - According to one embodiment, a network monitoring apparatus includes an unauthorized node determination module, a spoofed address resolution protocol request transmission module, and a spoofed address resolution protocol reply transmission module. The unauthorized node determination module determines whether a sender node which transmits an address resolution protocol request packet is an unauthorized node. The spoofed address resolution protocol request transmission module transmits a spoofed address resolution protocol request packet to a target node corresponding to a target network address in the address resolution protocol request packet if the sender node is an unauthorized node. The spoofed address resolution protocol reply transmission module transmits to the unauthorized node a spoofed address resolution protocol reply packet which includes a predetermined physical address other than the physical address of the target node as a sender physical address and a network address of the target node as a sender network address. | 09-23-2010 |
20120005677 | Computing Machine and Method for Controlling Computing Machine - According to one embodiment, a computing machine includes an activation module configured to activate, in a first mode, a virtual machine using a first virtual storage includes a basic virtual storage file, an update differential virtual storage file, and a change differential virtual storage file, a allocating module configured to allocate a second virtual storage includes a data storage virtual storage file to the virtual machine, and a changing module configured to change the updating portion data in the update differential virtual storage file to unchanged portion data indicating a unchanged portion of the basic virtual storage file when the virtual machine is terminated, and to delete the updating data from the differential information in the update differential virtual storage file. | 01-05-2012 |
20120166524 | Information Processing Apparatus and Removable Media Management Method - According to one embodiment, an information processing apparatus includes an identifier generation module, an identifier write module, an identifier storage, and a removable media control module. The identifier generation module generates a media identifier for a removable medium connected to the information processing apparatus. The identifier write module writes the generated media identifier in a predetermined area in the removable medium. The identifier storage stores the generated media identifier in an identifier list. The removable media control module permits use of a removable medium which is newly connected to the information processing apparatus if a media identifier included in the identifier list is written in a predetermined area in the newly connected removable medium. | 06-28-2012 |
20120198007 | Electronic Apparatus, Communication Control Method and Communication Control System - According to one embodiment, an electronic apparatus includes a first storage, a second storage and a control module. The first storage stores a destination list including a first address indicating a destination of a first e-mail which has already transmitted. The second storage stores at least one of a white list and a black list, the white list including an address to which transmission of an e-mail is permitted, the black list including an address to which transmission of an e-mail is blocked. The control module blocks transmission of a second e-mail to a second address if the second address is not included in the white list or the second address is included in the black list in a block mode and issues an alert on the transmission of the second e-mail to the second address if the second address is not included in the destination list. | 08-02-2012 |
20120304294 | Network Monitoring Apparatus and Network Monitoring Method - According to one embodiment, a network monitoring apparatus includes an unauthorized node determination module, a spoofed address resolution protocol request transmission module, and a spoofed address resolution protocol reply transmission module. The unauthorized node determination module determines whether a sender node which transmits an address resolution protocol request packet is an unauthorized node. The spoofed address resolution protocol request transmission module transmits a spoofed address resolution protocol request packet to a target node corresponding to a target network address in the address resolution protocol request packet if the sender node is an unauthorized node. The spoofed address resolution protocol reply transmission module transmits to the unauthorized node a spoofed address resolution protocol reply packet which includes a predetermined physical address other than the physical address of the target node as a sender physical address and a network address of the target node as a sender network address. | 11-29-2012 |
20130238675 | INFORMATION PROCESSING APPARATUS, IMAGE FILE MANAGEMENT METHOD AND STORAGE MEDIUM - According to one embodiment, an information processing apparatus applied to a client management system managing desktop environments of client terminals comprises a first controller and a second controller. The first controller controls creation processing for first image files which are disk image files for the desktop environments and contain no information unique to the client terminals and difference files for formation of second image files respectively containing information unique to the client terminals based on the first image files. The second controller controls deletion processing for the difference file for which the second image file is completely acquired by a corresponding client terminal. | 09-12-2013 |
20130246596 | INFORMATION PROCESSING APPARATUS, CLIENT MANAGEMENT SYSTEM, AND CLIENT MANAGEMENT METHOD - According to one embodiment, an apparatus includes a client management module configured to manage first information which correlates with client terminal information, group information, and type information, the client terminal information indicating a client terminal, the group information indicating a group to which the client terminal belongs, and the type information indicating whether the client terminal is a client virtualization terminal that executes a virtual machine or a thin client terminal, a user management module configured to manage second information which correlates with a user account and the group information, and a group management module configured to manage third information, which correlates with the group information and a virtual image file. | 09-19-2013 |
20130247036 | INFORMATION PROCESSING APPARATUS, VIRTUAL IMAGE FILE CREATION SYSTEM, AND VIRTUAL IMAGE FILE CREATION METHOD - According to one embodiment, an information processing apparatus is configured to create a virtual image file executing a virtual machine by a virtualization client terminal. The apparatus includes a setting module. The setting module is configured to set, for the virtual image file, a domain name of a domain and a user ID and a password to participate in the domain, when the virtual image file is created. | 09-19-2013 |
