What is a common target for DNS poisoning attacks?

A common target for DNS poisoning attacks is the Domain Name System servers. DNS poisoning, also known as DNS spoofing, occurs when an attacker corrupts the DNS cache of a server, allowing them to redirect users attempting to access a legitimate website to a malicious one instead.

The Domain Name System plays a crucial role in translating human-readable domain names (like www.example.com) into IP addresses that computers use to communicate over the internet. By compromising DNS servers, attackers can manipulate the resolution process for domain names, effectively leading users to fraudulent websites that could be used for phishing, distributing malware, or other malicious activities.

Focusing on the other options shows that while web application servers, database management systems, and remote access servers might be targeted in various attacks, they do not directly relate to the specific mechanism of DNS poisoning. DNS servers are integral to the functioning of the internet, making them particularly appealing targets for this type of attack, which aims to undermine trust in the system that converts domain names to IP addresses.
