How can you mitigate an L3 DDoS attack?

Mitigation strategies for L3 DDoS attacks include: **Over-provisioning Bandwidth:** Having sufficient bandwidth to absorb attack traffic. **Rate Limiting:** Limiting the number of packets accepted from a single source. **Traffic Filtering:** Using firewalls and intrusion detection/prevention systems (IDS/IPS) to filter malicious traffic based on source IP, protocol, or packet characteristics. **Blackholing:** Dropping all traffic to the target IP address (last resort). **DDoS Mitigation Services:** Utilizing specialized services that scrub malicious traffic before it reaches your infrastructure. **Anycast Network:** Distributing traffic across multiple geographically diverse servers.
