Distributed denial of service (DDoS), happens when attackers send requests to a target’s IP address, causing the server or network to become overwhelmed, resulting in a denial-of-service to normal traffic. Symptoms of a DDoS attack: - a site or service is suddenly very slow or unavailable - suspicious amounts of traffic from a single IP or IP range - suspicious amounts of traffic from users who share the same profile, device, etc - odd traffic patterns, spikes at odd hours, etc Some methods to reduce or even to prevent DDoS: - monitor web traffic - restriction (for example country) - use cloud - increase bandwidth - have plans (for example security plans)
