ACK Flood is a DDoS technique that targets system availability by overloading infrastructure. This page explains the attack, mitigation capabilities, and the role of WEDOS Global.
Description
Floods the target with TCP ACK packets to exhaust server resources.
Mitigation Capabilities
Anycast: Yes, disperses ACK traffic across nodes.
NGINX Proxy: No, not suitable for TCP-level floods.
HAProxy: Yes, mitigates high ACK traffic volumes.
IDS Suricata: Yes, detects excessive ACK patterns.
WAF: No, irrelevant for TCP-level floods.
OWASP Rules: No, unrelated to ACK traffic.
Complex anycast solution – WEDOS Global (or Cloudflare for example): Yes, mitigates ACK floods efficiently.
Solutions
Use firewalls and rate-limiting tools to filter abnormal ACK traffic.
