If you\u2019re eager to understand how this security protocol protects websites from cyberattacks, keep reading for practical explanations and expert advice.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Every time you visit a website, your device relies on the Domain Name System (DNS) to find the right address. But what if that system was tricked, and you were redirected to a fake site? That\u2019s exactly what attackers do through <strong>DNS spoofing<\/strong> and <strong>cache poisoning<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To solve this, <strong>DNSSEC (Domain Name System Security Extensions)<\/strong> was introduced.
