What is a DDoS Attack?
A Distributed Denial of Service (DDoS) attack is a malicious attempt to disrupt the normal traffic of a targeted server, service, or network by overwhelming the target with a flood of internet traffic. Attackers often use a botnet, a network of infected computers or IoT devices controlled remotely, to launch these attacks.
DDoS attacks aim to make services unavailable, causing downtime, financial loss, and reputational damage. They can target websites, online applications, APIs, or even entire networks.
Common Types of DDoS Attacks:
- Volume-Based Attacks: Flood the network with high traffic (e.g., UDP floods, ICMP floods).
- Protocol Attacks: Exploit weaknesses in network protocols (e.g., SYN floods, Ping of Death).
- Application Layer Attacks: Target specific applications or services (e.g., HTTP floods).
How to Mitigate DDoS Attacks:
- Use a Content Delivery Network (CDN) to distribute traffic.
- Implement a Web Application Firewall (WAF) to filter malicious requests.
- Monitor traffic patterns and set automated rate-limiting rules.
- Have a response plan with your hosting provider or cybersecurity team.
Understanding DDoS attacks is critical for maintaining uptime, security, and customer trust. Regular testing and proper network architecture can help mitigate the impact of these attacks.
