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.
