DNS spoofing, also referred to as DNS cache poisoning, is a form of computer security hacking in which corrupt Domain Name System data is introduced into the DNS resolver 's cache, causing the name server to return an incorrect result record, e.g. an IP address. This results in traffic being diverted to any computer that the attacker chooses.
DNS hijacking, DNS poisoning, or DNS redirection is the practice of subverting the resolution of Domain Name System (DNS) queries. [1] This can be achieved by malware that overrides a computer's TCP/IP configuration to point at a rogue DNS server under the control of an attacker, or through modifying the behaviour of a trusted DNS server so that it does not comply with internet standards .
Cache poisoning refers to a computer security vulnerability where invalid entries can be placed into a cache, which are then assumed to be valid when later used. [1] Two common varieties are DNS cache poisoning [2] and ARP cache poisoning. Web cache poisoning involves the poisoning of web caches [3] (which has led to security issues in ...
DNSSEC was designed to protect applications using DNS from accepting forged or manipulated DNS data, such as that created by DNS cache poisoning. All answers from DNSSEC protected zones are digitally signed. [1] By checking the digital signature, a DNS resolver is able to check if the information is identical (i.e. unmodified and complete) to the information published by the zone owner and ...
Kaminsky was known among computer security experts for his work on DNS cache poisoning, for showing that the Sony Rootkit had infected at least 568,000 computers, [4] and for his talks at the Black Hat Briefings. [3] On June 16, 2010, he was named by ICANN as one of the Trusted Community Representatives for the DNSSEC root. [5]
In computer networking, ARP spoofing, ARP cache poisoning, or ARP poison routing, is a technique by which an attacker sends ( spoofed) Address Resolution Protocol (ARP) messages onto a local area network. Generally, the aim is to associate the attacker's MAC address with the IP address of another host, such as the default gateway, causing any traffic meant for that IP address to be sent to the ...
The Domain Name System ( DNS) is a hierarchical and distributed name service that provides a naming system for computers, services, and other resources in the Internet or other Internet Protocol (IP) networks. It associates various information with domain names (identification strings) assigned to each of the associated entities. Most prominently, it translates readily memorized domain names ...
The Google service also addresses DNS security. A common attack vector is to interfere with a DNS service to achieve redirection of web pages from legitimate to malicious servers. Google documents efforts to be resistant to DNS cache poisoning, including “Kaminsky Flaw” attacks as well as denial-of-service attacks. [10]
