In some aspects, the power is then cut once the tissue impedance level exceeds the “bathtub region.” By gradually reducing the power, a balance is achieved between still applying an effective level of power for sealing and prolonging the time in which the tissue impedance remains in the “bathtub region.” |

Efficient threat context-aware packet filtering for network protection
A threat intelligence gateway (TIG) may protect TCP/IP networks from network (e.g., Internet) threats by enforcing certain policies on in-transit packets that are crossing network boundaries. The policies may be composed of packet filtering rules with packet-matching criteria derived from cyber threat intelligence (CTI) associated with Internet threats. These CTI-derived packet-filtering rules may be created offline by policy creation and management servers, which may distribute the policies to subscribing TIGs that subsequently enforce the policies on in-transit packets. Each packet filtering rule may specify a disposition that may be applied to a matching in-transit packet, such as deny/block/drop the in-transit packet or pass/allow/forward the in-transit packet, and also may specify directives that may be applied to a matching in-transit packet, such as log, capture, spoof-tcp-rst, etc. Often, however, the selection of a rule's disposition and directives that best protect the associated network may not be optimally determined before a matching in-transit packet is observed by the associated TIG. In such cases, threat context information that may only be available (e.g., computable) at in-transit packet observation and/or filtering time, such as current time-of-day, current TIG/network location, current TIG/network administrator, the in-transit packet being determined to be part of an active attack on the network, etc., may be helpful to determine the disposition and directives that may best protect the network from the threat associated with the in-transit packet. The present disclosure describes examples of methods, systems, and apparatuses that may be used for efficiently determining (e.g., accessing and/or computing), in response to the in-transit packet, threat context information associated with an in-transit packet. The threat context information may be used to efficiently determine the disposition and/or one or more directives to apply to the in-transit packet. This may result in dispositions and/or directives being applied to in-transit packets that better protect the network as compared with solely using dispositions and directives that were predetermined prior to receiving the in-transit packet. |

Using smart groups for computer-based security awareness training systems
This disclosure describes embodiments of an improvement to the static group solution because all the administrator needs to do is specify the criteria they care about. Unlike static groups, where the administrator needs to keep track of the status of individual users and move them between static groups as their status changes, smart groups allows for automatic identification of the relevant users at the moment that action needs to be taken. This feature automates user management for the purposes of enrollment in either phishing and training campaigns. Because the smart group membership is determined as the group is about to be used for something, the smart group membership is always accurate and never outdated. The query that determines the smart group membership gets run at the time when you are about to do a campaign or perform some other action that needs to know the membership of the smart group. |

Methods, apparatuses and systems for assigning IP addresses in a virtualized environment
Some embodiments use proxies on host devices to capture broadcast DHCP traffic in a network. Each host in some embodiments executes one or more virtual machines (VMs). In some embodiments, a proxy operates on each host between each VM and the underlying network. For instance, in some embodiments, a VM's proxy operates between the VM and a physical forwarding element executing on the VM's host. To suppress DHCP broadcast, the proxy for a particular VM monitors the VM's traffic to detect and intercept a DHCP discover message. When the proxy receives a DHCP discover message, the proxy retrieves DHCP configuration data that was previously stored on the host for the VM. In some embodiments, the DHCP configuration data is stored on the host for the VM during the installation of the VM in response to an administrator's request or as part of an installation script that installs the VM. The DHCP configuration data in some embodiments is stored in one common data store for all the VMs that execute on the host, while in other embodiments, each VM's DHCP configuration data is stored in a DHCP data store that is uniquely maintained for the VM. In some of these latter embodiments, the data in the unique DHCP data store for a VM can easily migrate with the VM when the VM migrates from one host to another host. |

Interference monitoring in radio communication systems
Apparatus and methods for monitoring interference in radio communication systems are provided. In certain embodiments, an interference monitor system for a ground terminal detects for interference based on a sum of the power levels of orthogonal polarizations of detected interference, thereby allowing the total and average peak interference power levels to be obtained independent of interference polarization. Further, the interference can be divided into frequency bins over the received signal bandwidth(s), thereby facilitating measurement of interference spectral characteristics. Multiple interference monitors can be included to detect interference over the full angular range over which potential interference has access as well as to determine an angular direction of the interference. |
