Over the years, it has become much easier for cyber criminals to launch DDoS attacks. These DDoS statistics show that the security of network infrastructure against cyber criminals is extremely vital. Distributed Denial of Service (DDoS) attacks overwhelm the resources of the affected network.  A monitoring method is crucial for identifying malicious attacks against cyber systems. DDoS attacks are evolving every day, and that is the reason it has become essential for businesses to opt for effective DDoS mitigation strategies rather than depending on traditional anti-DDoS software and tools that are no longer potent to offer enough protection against such attacks.
