ACK and PUSH ACK Flood

ACK and PUSH 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

This attack involves sending large amounts of ACK packets with PUSH flags to overwhelm the target server, exhausting its resources.

Mitigation Capabilities

Anycast: Yes, distributes the attack load across multiple nodes.

NGINX Proxy: Partially, helps with rate limiting but not specialized for ACK floods.

HAProxy: Yes, effective in managing high levels of TCP traffic.

IDS Suricata: Yes, can detect and filter malicious ACK flood traffic.

WAF: No, WAFs are not designed for handling ACK floods.

OWASP Rules: No, these rules target HTTP-specific threats.

Complex anycast solution – WEDOS Global (or Cloudflare for example): Partially, effective at absorbing traffic but less so at TCP-level filtering.

Solutions

Use specialized DDoS mitigation appliances and TCP-level filtering.

Why WEDOS Global?
