Embodiment Construction

[0028] The deployment of the DNS cache poisoning detection device of the present invention in the network is as follows: figure 1 As shown, the DNS traffic between the DNS recursive server and the DNS authoritative server and between the DNS recursive server and the DNS end user is mirrored to the DNS packet analyzer through the switch for DNS cache poisoning detection.

[0029] The DNS cache poisoning detection process of this embodiment is as follows figure 2 shown. Its steps are described as follows:

[0030] For DNS recursive servers and DNS authoritative servers:

[0031] 1) The DNS packet analyzer receives DNS traffic between the mirrored DNS recursive server and the DNS authoritative server.

[0032] 2) The DNS message analyzer parses the network domain name address information in the DNS response message, saves it in the memory of the DNS message analyzer, and counts the number of responses to the domain name.

[0033] 3) When the statistical period (eg, 1 minute)...

Abstract

The invention discloses a cache infection detection method and apparatus based on a deep analysis on a DNS message. Therefore, a DNS cache infecting attack can be detected timely and warning is carried out. Moreover, after DNS cache infection, a change of a network domain name address in the DNS server cache can be reported accurately, so that the DNS server operaton and maintennace personnel can correct the wrong network domain name address in the DNS server timely.

Description

technical field [0001] The invention belongs to the technical field of computer network security, and relates to a cache poisoning detection method and device based on deep analysis of DNS messages. Background technique [0002] In computer network communication, hosts need to know the IP address of the communication peer to be able to communicate with each other through the IP network. However, the 32-bit IPv4 address (the IPv6 address is 128 bits) is not easy for the communication participants to remember. Therefore, more intuitive domain names (such as www.google.com.hk) are widely used to solve the problem of difficult memory of IP addresses. However, network communication is based on the IP protocol, and the host to be accessed cannot be directly found through the domain name. Therefore, the host needs to convert the domain name entered by the user into an IP address. This process is called domain name resolution. [0003] In order to complete domain name resolution,...
