A distributed denial-of-service attack overwhelms a website or service with traffic. The practical response combines upstream filtering, resilient hosting, monitoring, and a clear escalation path.
Why it matters
What business leaders should understand
Even when attackers do not steal data, an unavailable website can interrupt sales, client communication, and trust. Preparation matters because filtering is most effective before traffic reaches an overloaded origin server.
The right response should reflect your environment, data, vendors, risk, and operational priorities. Use this guide as a practical starting point, then validate important decisions with the people responsible for your technology, cybersecurity, legal obligations, and insurance coverage.
