How Do DDoS Attacks Work?
DDoS attacks employ different techniques, such as flooding the target server with a massive volume of illegitimate requests or exploiting vulnerabilities to saturate all open ports, overwhelming the server’s capacity. These attacks take advantage of the server’s limited resources and processing power, rendering it unable to respond to legitimate user requests.
One common method used in DDoS attacks is flooding, where a large number of compromised devices, also known as bots, simultaneously send an overwhelming amount of traffic to the target server. This flood of requests creates congestion and exhausts the server’s resources, causing it to slow down or crash altogether.
Another technique is the Smurf Attack, where the attacker spoofs the source IP addresses of the requests to the target server. When the server responds to these requests, the responses flood the target, amplifying the impact of the attack. This can further strain the server’s resources and disrupt its normal functioning.
A SYN flood is another common method used in DDoS attacks. It takes advantage of the three-way handshake process that establishes a connection between a client and a server. By sending a flood of incomplete connection requests to the target server, the attacker overwhelms the server’s ability to handle new requests, effectively denying legitimate users the ability to connect.
| Technique | Description |
|---|---|
| Flooding | Overwhelming the target server with a massive volume of illegitimate requests. |
| Smurf Attack | Spoofing source IP addresses to flood the target with amplified responses. |
| SYN flood | Saturating all open ports with incomplete connection requests, denying legitimate users access. |
