Abstract: An impression tool for providing an impression of an object in a borehole includes a block held by a gripper. The block has a plurality of discrete elements that can deform or move so as to create an impression of an impacted object. The bock can be formed of knitted wire mesh. The tool is impacted on an object such that an impression is formed in the block.

Abstract: An impression tool for providing an impression of an object in a borehole. The tool comprises a block held by a gripper. The block comprises a plurality of discrete elements that deform or move so as to create an impression of an impacted object. In use, the tool is impacted on an object such that an impression is formed in the block. In a preferred embodiment, the block is formed from a knitted wire mesh.

Abstract: A running tool for landing and setting a retrievable downhole tool at any location in a well bore includes an inner rod, a running tool anchoring device mounted on the inner rod and controllably reconfigurable between a retracted configuration to permit movement of the tool through the well bore and a radially extended configuration for locking engagement of the running tool with the bore wall, a running tool actuating assembly for effecting reciprocal movement of the reconfiguring the running tool anchoring device to and from the retracted and expanded configurations without interacting with any restrictions or recesses within the well bore, and a resistance device for frictionally engaging the bore wall with sufficient gripping force so as to hold the position of the running tool relative to the well bore during movement of the running tool actuating assembly to and from the first and second configuration upon application of the axial force.

Abstract: A zone locking system detects unauthorized network usage internal to a firewall. The system determines unauthorized network usage by classifying internal hosts inside a firewall into zones. Certain specified zones are unauthorized to initiate client communications with other selected zones. However, zone override services can be designated for each associated internal zone, and thus, authorizing selected network services. An alarm or other appropriate action is taken upon the detection of unauthorized network usage.

Abstract: A port profiling system detects unauthorized network usage. The port profiling system analyzes network communications to determine the service ports being used. The system collects flow data from packet headers between two hosts or Internet Protocol (IP) addresses. The collected flow data is analyzed to determine the associated network service provided. A host data structure is maintained containing a profile of the network services normally associated with the host. If the observed network service is not one of the normal network services performed as defined by the port profile for that host, an alarm signal is generated and action can be taken based upon the detection of an Out of Profile network service. An Out of Profile operation can indicate the operation of a Trojan Horse program on the host, or the existence of a non-approved network application that has been installed.

Abstract: A downhole tool and a running tool are described, each being retrievably settable within a suitably sized cased well bore without the need for any interaction between the downhole tool or the running tool and any restrictions or recesses in the well bore to land, anchor or retrieve either tool. The downhole tool has a mandrel, an anchoring means mounted on the mandrel and controllably reconfigurable from a retracted configuration to permit movement of the downhole tool through the well bore to a radially expanded configuration for releasably engaging the cased well bore. The downhole tool anchoring means is reconfigured using a ratchet that resists movement of the tool anchoring means from the expanded configuration back to the retracted configuration until a release mechanism is released to allow retraction of the downhole tool anchoring means and retrieval of the downhole tool from the well bore.

Abstract: A flow-based intrusion detection system for detecting intrusions in computer communication networks. Data packets representing communications between hosts in a computer-to-computer communication network are processed and assigned to various client/server flows. Statistics are collected for each flow. Then, the flow statistics are analyzed to determine if the flow appears to be legitimate traffic or possible suspicious activity. A concern index value is assigned to each flow that appears suspicious. By assigning a value to each flow that appears suspicious and adding that value to the total concern index of the responsible host, it is possible to identify hosts that are engaged in intrusion activity. When the concern index value of a host exceeds a preset alarm value, an alert is issued and appropriate action can be taken.
