Abstract: A computer security vulnerability remediation system (CSVRS) is disclosed, including a CSVRS client communicatively coupled to a remediation server through a network. The CSVRS client includes software having a security vulnerability, which vulnerability may be known to malicious actors who develop an exploit. In some cases, the exploit is a “zero-day exploit,” meaning the vulnerability may not be known to the CSVRS client until the exploit is deployed. A RSP receives information about the exploit and vulnerability from a team of remediation experts. The RSP may prepare a remedial exploit, which carries a self-healing pay load. The remedial exploit may be delivered either through the vulnerability itself, or through credentials granted by the CSVRS client to the RSP. The self-healing pay-load takes appropriate action, such as closing ports or disabling scripts, to prevent the vulnerability from being further exploited.

Abstract: The present invention provides a new method for policy enforcement in a virtualized or cloud environment. We break down the environment into layers, which are further sub-divided into security units. Each security unit has a security profile based on its own security properties and those of the layers below. The security profile also reflects the floor, ceiling and wall security properties. Each security unit has an agent which is used to establish communications with other security units. Such communication is mediated by a cloud trust broker which determines if the communication is permitted based on access control list or else retrieves the security profiles and applies pre-defined rules. If the communications are allowed the cloud trust broker runs a mutual authentication and key distribution protocol that results in the two security units obtaining a session key which they can then use for further communications which can proceed directly.

Abstract: The present invention relates to drilling apparatus which includes a steerable bottom hole assembly for use in a well bore. The steerable bottom hole assembly includes a bent sub assembly connectable to a distal end of a drill string. It also has a control bias unit connected to the bent sub assembly and a drill bit connected to the control bias unit. The bent sub assembly may have an adjustable angle.
