Mechanisms to prevent DDoS attack

There are several mechanisms that can help prevent DDoS attacks.

Here are some common ones:

Network security measures: These include firewalls, intrusion prevention systems (IPS), and other security appliances that can detect and block malicious traffic before it reaches your network.

Traffic filtering: This involves filtering out traffic from known malicious IP addresses or blocking traffic that matches specific patterns that are commonly used in DDoS attacks.

Rate limiting: This involves limiting the amount of traffic that can be sent to a server or network, which can help prevent overwhelming traffic spikes.

Content Delivery Networks (CDNs): CDNs can help distribute traffic across multiple servers, which can help prevent a single server from becoming overwhelmed.

Anti-DDoS software: These are specialized software applications that can detect and block malicious traffic in real-time.

Cloud-based DDoS protection services: These services use a combination of network security measures, traffic filtering, rate limiting, and anti-DDoS software to protect against DDoS attacks.

It's important to note that no single mechanism can provide complete protection against DDoS attacks. A combination of these measures, along with regular testing and updating of security systems, can help mitigate the risk of a DDoS attack
