DDoS Attacks: Detection and Mitigation Strategies

 In today’s digital era, cyber threats are more sophisticated than ever. One of the most dangerous and common threats to online services is the DDoS (Distributed Denial of Service) attack. At iHub Training Institute, we train aspiring cybersecurity professionals to understand, detect, and defend against such attacks through hands-on, industry-relevant training.


What is a DDoS Attack?

A DDoS attack is an attempt to make an online service unavailable by overwhelming it with traffic from multiple sources. These sources are often part of a botnet — a network of infected devices controlled remotely by attackers.

Common targets include:

  • Websites
  • Banking systems
  • Gaming servers
  • Government portals
  • Cloud-based platforms


Types of DDoS Attacks

Volume-Based Attacks – Flood the bandwidth using massive traffic (e.g., UDP Flood).

Protocol Attacks – Exploit weaknesses in network protocols (e.g., SYN Flood).

Application Layer Attacks – Target specific applications or services (e.g., HTTP GET/POST floods).


Detection Strategies

Detecting DDoS attacks early is critical to minimizing damage. Key detection methods include:


1. Traffic Pattern Analysis

Sudden spikes in incoming traffic, especially from unknown or unusual IPs, often indicate an attack.


2. Baseline Behavior Monitoring

Understanding what "normal" traffic looks like helps in quickly spotting anomalies.


3. Use of Intrusion Detection Systems (IDS)

Tools like Snort or Suricata can alert you to unusual activity across networks.


4. Rate-Based Detection

Set thresholds for requests per second — exceeding these could flag a DDoS event.


Mitigation Strategies

1. Firewalls and Rate Limiting

Basic but effective—filters incoming traffic and limits requests from suspicious IPs.


2. CDN and Load Balancers

Services like Cloudflare or AWS Shield distribute traffic across multiple servers to reduce load.


3. Blackhole Routing

Suspicious traffic is rerouted to a “black hole” where it’s discarded before reaching the network.


4. Behavior-Based Filtering

Machine learning algorithms can distinguish between real users and bot traffic in real-time.
