What are common defensive measures that can be implemented against Python-based DDoS attacks?

Defensive measures include implementing rate limiting to restrict the number of requests from a single IP address, using a Web Application Firewall (WAF) to filter malicious traffic, utilizing Content Delivery Networks (CDNs) to distribute the load, and employing intrusion detection and prevention systems (IDS/IPS) to identify and block attack patterns. Blacklisting suspicious IP addresses and configuring network hardware (routers and switches) to filter or prioritize traffic are other mitigation strategies.
