1. Traffic monitoring and analysis: Regularly monitor your network traffic for early detection of anomalies. Use traffic analysis tools so that you can identify DDoS attacks and act accordingly.

2. Traffic filtering: Intrusion detection systems (IDS) and intrusion prevention systems (IPS) are used to detect and filter harmful traffic. This can be done through hardware devices or cloud services.

3. Content Delivery Network (CDN) : Deploying your website on a CDN can spread traffic and reduce the burden on the server. A CDN can cache and serve content closer to the user, taking the strain off your original server.

4. Load balancing: Load balancing devices or services are used to distribute traffic to multiple servers. This ensures that even if one server is attacked, the other servers can still handle the request.

5.DDoS Protection Services: Consider using specialized DDoS protection services, which often have robust infrastructure and expertise to effectively defend against all types of DDoS attacks.

6. Configure firewalls: Ensure that the firewalls on your network devices and servers are correctly configured to allow only legitimate traffic through. This can be achieved by implementing access control policies such as whitelisting and blacklisting.

7.DDoS Attack Response Plan: Develop and test a DDoS attack response plan so that measures can be taken quickly and effectively in the event of an attack. This may include upgrading bandwidth, adjusting firewall rules, and so on.

8. Cloud service Provider support: If you use cloud services, understand the DDoS protection services offered by your cloud service provider and make sure you can quickly call on these services if you need them.
