Abstract: A method and system for running, on different computers at the same time, multiple operating systems from the same shared system resource is provided. This is accomplished, for example, by using persistent elemental disk reservations. Each machine reads the master boot record without reservation to determine the partition of the operating system to be booted. Each machine then makes an elemental exclusive write persistent reservation for accessing the operating system boot partition. This is followed by each machine making another elemental exclusive write persistent reservation for accessing the operating system partition itself. Each machine is assigned a different operating system partition even if they are running the same operating system. The unique reservation key for these reservations is created from at least on of a Processor ID, a Cluster ID, a Multiple Processor partition ID, a Non-Uniform Memory Access complex ID, and/or a Non-Uniform Memory Access node ID.

Abstract: There is provided a user friendly display interface system for the interactive handling and sorting out of windows in complex window hierarchical graphical user interfaces. The system provides for the storage of a hierarchy of windows which are displayable to overlap each other in a selected order whereby a plurality of said windows are partially visible. Apparatus is provided for displaying on a display screen a plurality of these partially overlapping windows. A different audio identifier is provided and stored for each of these windows. Further apparatus is provided for moving around and positioning a pointing device, such as a cursor on the display screen, in combination with means responsive to the pointing device for announcing the audio identifier for each window which said pointing device enters. The pointing device may be a user controlled cursor, a stylus or even a finger in touch sensitive display systems. The audio identifier may conveniently be the name in the title bar of the window.

Abstract: Provided are techniques for to enable a virtual input/output server (VIOS) to establish cryptographically secure signals with target LPARs to detect an imposter or spoofing LPAR. The secure signal, or "heartbeat," may be configured as an Internet Key Exchange/Internet Protocol Security (IKE/IPSec) encapsulated packet (ESP) connection or tunnel. Within the tunnel, the VIOS pings each target LPAR and, if a heartbeat is interrupted, the VIOS makes a determination as to whether the tunnel is broken, the corresponding LPAR is down or a media access control (MAC) spoofing attack is occurring. The determination is made by sending a heartbeat that is designed to fail unless the heartbeat is received by a spoofing device.

Abstract: A computer implemented method, data processing system, and computer program product for discovering an unauthorized router in a network. The process in the illustrative embodiments first obtains a physical address of a suspected router or destination device. A data packet is created which comprises at least a destination media access control field, a destination internet protocol field, and a time-to-live field, wherein the destination media access control field comprises the physical address of the destination device, wherein the destination internet protocol field comprises a bogus internet protocol address, and wherein the time-to-live field comprises a value indicating the data packet has exceeded a time limit. The data packet is sent to the destination device using the physical address in the destination media access control field. If a time exceeded message is received from the destination device, the destination device is determined to be enabled for routing.

Abstract: Se describe un método implementado por computadora, aparato y producto de computadora para la protección de barrido de puertos. Un paquete de datos de respuesta que tiene un encabezado de protocolo de control de transmisión modificado es generado para formar un paquete de datos de respuesta modificado en respuesta a la detección de un barrido de puertos. El paquete de datos de respuesta modificados producirá alguna respuesta de un receptor del paquete de datos modificado. El paquete de datos de respuesta es enviado a una primera dirección de protocolo de Internet asociada con el barrido de puertos. Una segunda dirección de protocolo de Internet es identificada de un encabezado de respuesta al paquete de datos de respuesta modificado. La segunda dirección de protocolo de Internet es una dirección de promotor de Internet de una fuente de barrido de puertos. Todo el tráfico de red de la segunda dirección de protocolo de Internet puede ser bloqueado para impedir un ataque sobre cualesquier puertos abiertos de la fuente del barrido de puertos.

Abstract: The present invention involves the recognition that since an eavesdropper listening adjacent to a wireless LAN is likely to be mobile and operating on a short time cycle, he himself is likely to be wirelessly transmitting his tes t message. Consequently, the present invention provides the combination of apparatus for eavesdropping within an area layer adjacent to and surrounding the LAN area periphery for potential wireless transmissions of an intruder having a lower frequency within a level below the LAN frequency and addresse d to the network location of any one of the computer terminals in the LAN; and an implementation responsive to said eavesdropping means for changing the encryption code of said encrypted wireless transmission upon the eavesdroppi ng detection of a wireless transmission of said lower frequency addressed to a network location of one of the terminals in said LAN. There is the recogniti on that there are several factors contributing to the success of the process of the invention. It is likely that the intruder must send his message at a low er frequency than the 2.4 GHz frequency of the LAN area transmissions because t he intruder will probably have to reach a base station tower over a longer distance or range than the adjacent target wireless LAN facility. This insur es thatthe eavesdropping of the present invention will be at a lower frequency and, thus, not interfered with by the transmissions within the LAN.

Abstract: Disclosed is a system and method for enhancing the security and reliability of virtual private network (VPN) connections by manually exchanging secondary configuration information. If a compromise is detected on a main VPN tunnel, a new VPN tunnel can be created by the system administrators using the secondary configuration, stymieing attempted security violations and providing nearly continuous service to the users. A compromise may be indicative of a security breach or other problem with the VPN. The main VPN tunnel may be abandoned or fed with false data to confuse would-be intruders if the compromise is a security compromise.

Abstract: A security protocol that dynamically implements enhanced mount security of a filesystem when access to sensitive files on a networked filesystem is requested. When the user of a client system attempts to access a specially-tagged sensitive file, the server hosting the filesystem executes a software code that terminates the current mount and re-configures the server ports to accept a re-mount from the client via a more secure port. The server re-configured server port is provided the IP address of the client and matches the IP address during the re-mount operation. The switch to a secure mount is completed in a seamless manner so that authorized users are allowed to access sensitive files without bogging down the server with costly encryption and other resource-intensive security features. No significant delay is experienced by the user, while the sensitive file is shielded from un-authorized capture during transmission to the client system.

Abstract: A dynamic buffer is used to display an object from a document. The cut object is visible to the user as the floating cursor is positioned to a desired insertion point. The cut object can be any combination of text, graphics or data. The display can move in conjunction with the floating cursor or be parked at a predetermined or user-selected position. The cut object can be abbreviated to fit the display, or the display can be sized or scrolled. Once an object has been cut and thus stored in the dynamic buffer, it can be edited, or pasted to a new location or merely deleted.
