Abstract: A radio frequency identification (RFID) system first interrogates, in a first mode, one or more particular target zones of the plurality of target zones including a given target zone. Each particular target zone is interrogated with one of the antennas at a time at a first power for the particular target zone. The RFID system monitors, upon first interrogating, for a trigger condition to occur. In response to the trigger condition not occurring, the RFID system continues the first interrogation in the first mode. In response to the trigger condition occurring, the RFID system second interrogates the given target zone in a second mode at a second power with a plurality of the antennas. The second power for the given target zone is greater in an aggregate across the second interrogating antennas than the first power for the given target zone.

Abstract: Presented herein are techniques for automatically generating information about risks associated with browser extensions used by browsers in an enterprise network for purposes of determining whether to whitelist a browser extension in response to a request from a user. A request to install a browser extension is obtained from a user device of a plurality of user devices associated with an organization, wherein the request comprises an extension identifier for the browser extension. A risk score is generated for the browser extension based on risk values for each of one or more permissions requested by the browser extension. The risk score is compared to a threshold value to determine whether the browser extension satisfies risk standards of the organization, and if so, the browser extension is automatically added to a whitelist of permitted extensions for future installation on the plurality of user devices.
