Abstract: A computer implemented method, apparatus, and computer program product for port scan protection. A reply data packet having a modified transmission control protocol header is generated to form a modified reply data packet, in response to detecting a port scan. The modified reply data packet will illicit a response from a recipient of the modified data packet. The reply data packet is sent to a first Internet protocol address associated with the port scan. A second Internet protocol address is identified from a header of the response to the modified reply data packet. The second Internet protocol address is an actual Internet protocol address of a source of the port scan. All network traffic from the second Internet protocol address may be blocked to prevent an attack on any open ports from the source of the port scan.

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 reconfigures the server ports to accept a re-mount from the client via a more secure port. The server reconfigured 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 unauthorized capture during transmission to the client system.

Abstract: Apparatus for eavesdropping within an area layer adjacent to and surrounding a LAN area periphery for potential wireless transmissions of an intruder having a lower frequency within a level below the LAN frequency; and an implementation responsive to said eavesdropping apparatus for changing the encryption code of said encrypted wireless transmission upon the eavesdropping detection of a wireless transmission of said lower frequency addressed to a network location of one of the terminals in said LAN.

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 syste m 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 creat ed from at least on of a Processor ID, a Cluster ID, a Multiple Processor partition ID, a Non-Unifo rm Memory Access complex ID, and/or a Non-Uniform Memory Access node ID.

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: METHOD, APPARATUS, AND PROGRAM FOR PERFORMING BOOT, MAINTENANCE, OR INSTALL OPERATIONS ON A STORAGE AREA NETWORK A mechanism is provided for configuring a set of devices for a given machine attached to a storage area network (102). The initial program load firmware and network adapter firmware for each machine (104-108) on the storage area network (102) are modified to query a storage area network appliance (120) for lists of devices. The storage area network appliance (120) may be identified by a world wide name and may store lists of boot devices, root volume group devices, primary devices, and secondary devices for each machine on the storage area network. The storage area network appliance (120) then listens for queries and returns the appropriate list of devices based on query type and/or boot type. The boot type for a machine may be set to normal boot, maintenance boot, or install boot.
