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)
