DNS spoofing – How to protect ourselves?
The Domain Name System (DNS) is vulnerable to threats, and one of the most insidious among them is DNS spoofing. This deceptive technique poses a significant risk to both individuals and organizations, compromising data security and potentially leading to devastating consequences. In this blog post, we will understand its mechanisms, explore its consequences, and, most importantly, learn how to safeguard ourselves against this cyber menace.
What is DNS Spoofing?
DNS spoofing, also known as DNS cache poisoning or DNS poisoning, is a malicious act wherein attackers manipulate the DNS resolution process to redirect legitimate domain name requests to fraudulent IP addresses. This manipulation is achieved by injecting falsified data into the DNS cache of a recursive resolver, leading users to believe they are accessing authentic websites when, in reality, they are redirected to malicious ones.
