A computer network device that includes a plurality of computer network ports for connecting to a plurality of computer network nodes is disclosed. The computer network device includes switching circuitry that communicates each of a plurality of messages received by more than one of the plurality of computer network ports to at least one other computer network port for transmission. The computer network device also includes a management processor that includes a plurality of management processor communication ports that include at least one externally accessible communication port and at least one externally inaccessible communication port. The at least one externally inaccessible communication port is in communication with the switching circuitry, and the management processor sends switching circuitry configuration instructions via the at least one externally inaccessible communication port to configure the switching circuitry.

Provided are a control method and device for a data packet duplication function, and a communication device. The control method for the data packet duplication function includes determining, by a communication device, to deactivate or activate a data packet duplication function; and performing, by the communication device, an operation of deactivating or activating the data packet duplication function correspondingly. Further provided is a storage medium.

A communication device communicates a radio frame including a preamble and a data field of a physical layer (PHY). The preamble includes an L-STF (Legacy Short Training Field), an L-LTF (Legacy Long Training Field), an L-SIG (Legacy Signal Field), an EHT-SIG-A (Extremely High Throughput Signal A Field), an EHT-STF, and an EHT-LTF, and the EHT-SIG-A includes a field indicating a standard that the radio frame complies with.

Systems and methods for detecting suspicious malware by analyzing data such as transfer protocol data or logs from a host within an enterprise is provided. The systems and methods include a database for storing current data and historical data obtained from the network and a detection module and an optional display. The embodiments herein extract information from non-encrypted transfer protocol metadata, determine a plurality of features, utilize an outlier detection model that is based on historical behaviors, calculate a suspiciousness score, and create alerts for analysis by users when the score exceeds a threshold. In doing so, the systems and methods of the present invention improve the ability to identify suspicious outliers or potential malware on an iterative basis over time.
