    Abstract: A method and system for an algorithm-based network snoop avoider is provided. A first data processing system and a second data processing system communicate on a physical network by transmitting data packets on the network using a virtual private network (VPN). Data packets are transmitted through a first VPN tunnel between the first data processing system with a first network address terminating a first end of the VPN tunnel and the second data processing system with a second network address terminating a second end of the first VPN tunnel. The VPN is automatically reconfigured to use alternate addresses on the network for the tunnel endpoints by automatically determining, in accordance with a predetermined algorithm, a third network address and a fourth network address and by automatically assigning the third network address to the first data processing system and the fourth network address to the second data processing system. Data packets may then be transmitted through a second VPN tunnel in which a first end of the second VPN tunnel is terminated by the first data processing system using the third network address and a second end of the second VPN tunnel is terminated by the second data processing system using the fourth network address. The data packets may be transmitted using Internet Protocol (IP), and a portion of the network may include the Internet.

    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: 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: 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.
