The invention discloses a network attack protection method, device and system and a medium, and the method comprises the steps: receiving a current network data packet, and carrying out the analysis of the current network data packet, and obtaining the data packet type of the current network data packet, the current network data packet is used for adding table item information to a target database of target network equipment in an OSPF network protocol; if the data packet type is a first data type, performing attack detection on the current network data packet based on link identification information of the current network data packet to obtain an attack detection result of the current network data packet; and executing a protection measure corresponding to the attack detection result. According to the method, under the condition that the data packet type is analyzed to be the first data type, attack detection is performed on the current network data packet based on the link identification information, and co
