DNS hijacking, DNS poisoning, or DNS redirection is the practice of subverting the resolution of Domain Name System (DNS) queries. 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 ...
DNS rebinding is a method of manipulating resolution of domain names that is commonly used as a form of computer attack. In this attack, a malicious web page causes visitors to run a client-side script that attacks machines elsewhere on the network. In theory, the same-origin policy prevents this from happening: client-side scripts are only ...
Domain generation algorithms (DGA) are algorithms seen in various families of malware that are used to periodically generate a large number of domain names that can be used as rendezvous points with their command and control servers. The large number of potential rendezvous points makes it difficult for law enforcement to effectively shut down ...
Contains the DNSSEC signature for a record set. DNS resolvers verify the signature with a public key, stored in a DNSKEY record. DNSKEY Contains the public key that a DNS resolver uses to verify DNSSEC signatures in RRSIG records. DS (delegation signer) Holds the name of a delegated zone. References a DNSKEY record in the sub-delegated zone.
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.
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.
The DNS root zone is the top-level DNS zone in the hierarchical namespace of the Domain Name System (DNS) of the Internet. Before October 1, 2016, the root zone had been overseen by the Internet Corporation for Assigned Names and Numbers (ICANN) which delegates the management to a subsidiary acting as the Internet Assigned Numbers Authority ...
DNSCrypt is a network protocol that authenticates and encrypts Domain Name System (DNS) traffic between the user's computer and recursive name servers. DNSCrypt wraps unmodified DNS traffic between a client and a DNS resolver in a cryptographic construction, preventing eavesdropping and forgery by a man-in-the-middle. [1]
