* Do you know what Flood Attack is?


Suggested page: Flood Attack: Prevention and Protection

A flood attack, a form of Distributed Denial of Service (DDoS) attack, overwhelms a system with excessive requests, preventing legitimate access. The goal is to exhaust the target's resources, such as bandwidth, memory, and processing power, causing service disruption or a complete crash. Attackers often use networks of compromised devices, known as botnets, to generate the massive traffic needed, making the source difficult to trace.

Types of Flood Attacks:

  • DNS Flood: Overloads DNS servers with lookup requests, often using fake IPs, making websites inaccessible by preventing them from resolving domain names.
  • SYN Flood: Exploits the TCP handshake by sending numerous SYN requests without completing the process, filling up connection slots and blocking legitimate users.
  • HTTP Flood: Mimics legitimate web traffic with a high volume of HTTP requests, exhausting server resources and delaying or denying access.
  • ICMP Flood: Overwhelms the target with ping requests, consuming bandwidth and processing power, leading to service failure.
  • UDP Flood: Sends excessive UDP packets to random ports, straining system resources and preventing legitimate requests.

Flood attacks are extremely dangerous, and protecting against them is crucial because they can severely disrupt services.
