Prevent DNS Cache Poisoning Attacks and Mitigate Risk with Two-factor Authentication

turn on 2fa

Prevent DNS Cache Poisoning with Two-factor Authentication. DNS Cache Poisoning capitalizes on the Domain Name System (DNS) server’s conversion of internet names to proper IP addresses. This technique can be an entry point into broad scale network server attacks.

DNS servers store a ‘cache’ repository of data so future online requests can be serviced more quickly. An effective attacker manipulates this repository or ‘cache’ to redirect traffic to another illegitimate website to glean account information. Implementing two-factor authentication will stop these infiltrations at onset, protecting users and systems against DNS cache poisoning attacks.
