A method and apparatus are disclosed whereby databases containing information related to an IP address are accessed directly from within a threat management software tool. When an alert is generated, an element within that alert, such as an IP address, is linked to one or more databases internal to an organization containing information related to the location or identity of a user or computer at a particular IP address. If no matches for that element are found in internal databases, a search of a registry of IP addresses is conducted. Finally, if the searches of internal and external databases are inadequate, an active scan of the device at that particular IP address or a router associated with that IP address is conducted. In this way, information related to a security threat is easily and efficiently obtained to enable a security analyst to better isolate that threat.

An N-way multi-layer radial power combiner / divider comprises an RF layer including N planar RF transmission lines radiating from a common port to N ports. An isolation layer substantially parallel to the RF layer comprises a star resistor having N resistive arms radiating from a common junction and N planar isolation transmission lines coupled in series to respective resistive arms. Each series pair of a resistive arm and an isolation transmission line is ideally a half-wavelength in electrical length. N vertical interconnects between the RF layer and the isolation layer connect the ends of the N isolation transmission lines to the ends of the N RF transmission lines at the N individual ports, respectively. Any path from one individual port through the common junction of the star resistor to another individual port is approximately a full wavelength λc or multiple thereof so that the phase angle through the isolation network is approximately zero degrees. This approach can achieve better isolation and power handling than the Wilkinson design while employing the benefits of planar metallization technology.
