Abstract

The invention provides a PING (Packet Internet Groper) packet detection method and device for a DNS (Domain Name System). The method comprises the following steps: receiving a PING packet from a sender on the DNS; resolving the PING packet, and determining whether the PING packet is a grey PING packet or not according to an attribute of the PING packet; and if the PING packet is the grey PING packet, determining that the sender is intruded. According to the method, whether the PING packet of the sender is the grey PING packet or not is determined on the DNS, so that whether an environment of the sender is changed or not can be found; and the vigilance of the DNS to the intruded sender can be enhanced. Processing such as filtering and deletion is performed on transmitted data packets (including PING packets), so that the DNS is prevented from being infected or attacked, and the security performance of the DNS is enhanced.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a PING packet detection method and device of Domain Name System (DNS for short). Background technique [0002] With the wide application of network technology, network security has become a research hotspot. At present, the existing detection technologies are mainly aimed at the attack detection of the network layer and the transport layer, and there is no related general solution for detection methods based on the application layer. The application layer needs to establish a communication connection with the server to ensure the normal operation of the application. At present, an Internet packet explorer (Packet Internet Groper, PING for short) is usually used to check whether the network with the server is connected, that is, the client is connected to the server, and is used to test the program of the network connection. [0003] Usually, some malicious programs su...
