Attackers overwhelm systems, servers, or networks with excessive traffic or malicious data, rendering them inaccessible to legitimate users. When multiple sources are involved, it\u2019s called a Distributed Denial-of-Service (DDoS) attack, making it even harder to mitigate. These attacks can cause significant downtime, financial losses, and reputational damage for businesses<span class=\"whitespace-nowrap\">.<\/span><\/p>\n<h4 class=\"mb-xs mt-5 text-base font-[525] first:mt-3\">How DoS Attacks Work<\/h4>\n<ul>\n<li>Flooding Traffic: Attackers send massive amounts of traffic to overwhelm resources.<\/li>\n<li>Exploiting Vulnerabilities: DoS attacks exploit weaknesses in software or protocols to crash systems.<\/li>\n<li>Nodes and IoT Devices: In DDoS attacks, compromised devices (botnets) amplify the assault<span class=\"whitespace-nowrap\">.<\/span><\/li>\n<\/ul>\n<div class=\"relative\">\n<h4 class=\"mb-2 mt-6 text-lg font-[500] first:mt-3\">Preventing DoS Attacks<\/h4>\n<p>There are some practical steps that can be taken to reduce the risk of a DoS attack:<\/p>\n<p class=\"prose text-pretty dark:prose-invert inline leading-normal break-words min-w-0 [word-break:break-word]\"><strong>Build Network Redundancy<\/strong><\/p>\n<p>Distribute resources across multiple locations so that no single point of failure exists.
