  • Abnormal packet detection apparatus and method
    Patent number: 11425094
    Abstract: An abnormal packet detection apparatus and method are provided. The abnormal packet detection apparatus stores a whitelist corresponding to a protocol port, wherein the whitelist includes at least one legal packet record. Each legal packet record includes a legal packet length, a legal source address, and a legal variation position set, and corresponds to a reference packet. The abnormal packet detection apparatus determines that a current packet length and a current source address of a to-be-analyzed packet are respectively the same as the legal packet length and the legal source address of a reference packet record among the at least one legal packet record, determines a current variation position of the to-be-analyzed packet by comparing the to-be-analyzed packet with the reference packet corresponding to the reference packet record, and generates a detection result by comparing the current variation position with the legal variation position set of the reference packet record.
