Abstract: A dynamic network feature processing device includes a storage device and a processor. The storage device is configured to store a plurality of malicious feature groups. Each of the malicious feature groups corresponds to a malicious feature, and each of the malicious feature groups includes a plurality of malicious network addresses. The processor is coupled to the storage device. The processor is configured to: acquire an unknown network address of an unknown packet; compare the unknown network address with the malicious feature of each of the malicious feature groups; and filter the unknown packet when determining that the unknown network address matches at least one of the malicious feature of the plurality of malicious feature groups.

Abstract: A monitor apparatus, method, and non-transitory computer readable storage medium thereof are provided. The monitor method is adapted for an electronic computing apparatus, wherein the electronic computing apparatus stores a smart contract and a blockchain ledger of a blockchain system. The monitor method periodically executes the following steps: (a) obtaining a piece of behavior information of a first electronic apparatus at a time point, (b) retrieving, via the smart contract, a plurality of pieces of previous behavior information within a time interval from the blockchain ledger, wherein the time interval is defined by the time point, and each piece of previous behavior information corresponds to one of a plurality of second electronic apparatuses and the first electronic apparatus, (c) determining a legality of the piece of behavior information according to the pieces of previous behavior information, and (d) writing the behavior information into the blockchain ledger.
