What is a distributed denial-of-service (DDoS) attack?
A Distributed Denial of Service (DDoS) attack is a type of cyberattack in which multiple compromised systems, often compromised by malware, are used to target a single website or network with the goal of overwhelming it with traffic and making it unavailable to legitimate users. These compromised systems, called "bots" or "zombies", are typically controlled by a single command-and-control server.
During a DDoS attack, the attackers use the bots to flood the targeted website or network with a large amount of traffic, which can include HTTP, DNS, and other types of requests. The traffic is typically generated from multiple sources, making it difficult to block. The goal of the attack is to exhaust the resources of the targeted website or network, making it unavailable to legitimate users.
DDoS attacks can be caused by various forms of network and application-layer traffic, and can be mitigated by different techniques like traffic filtering, rate limiting, scrubbing, proxying, blackholing, and more. DDoS attacks can have a significant impact on the availability of a website or network and can result in lost revenue, reputational damage, and other negative consequences.

Cloudflare DDos Protection
Cloudflare is a service that provides DDoS protection by routing traffic through its global network of servers before it reaches a client's website. This allows Cloudflare to absorb and mitigate DDoS attacks, ensuring that the client's website remains accessible to legitimate traffic. Cloudflare also provides other security and performance enhancements, such as caching and SSL/TLS encryption.
What is DDoS mitigation?
DDoS (Distributed Denial of Service) mitigation is the process of identifying and preventing DDoS attacks on a network or website. It involves a range of techniques and technologies that are used to detect and block malicious traffic while allowing legitimate traffic to pass through. The goal of DDoS mitigation is to minimize the impact of an attack and keep the targeted website or network online and available to legitimate users.
DDoS mitigation techniques include:
Traffic filtering: This involves identifying and blocking malicious traffic based on its source IP address, destination IP address, or other characteristics.
Traffic rate limiting: This involves limiting the amount of traffic that can be received from a specific IP address or range of IP addresses.
Scrubbing: This involves diverting traffic to a "scrubbing center" where it is analyzed and filtered to remove malicious traffic.
Proxying: This involves routing traffic through a proxy server that can filter and block malicious traffic.
Blackholing: This involves routing all traffic away from the targeted website or network during an attack.
These are just a few examples of the many different DDoS mitigation techniques that are available. The specific techniques and technologies used will depend on the type of attack and the resources available to the target.

Is Cloudflare good for DDoS protection?
Cloudflare is a well-known and reputable company that provides a wide range of security and performance enhancements, including DDoS protection. The company has a global network of data centers that can absorb and mitigate DDoS attacks before they reach a client's website, which can help ensure that a website remains accessible to legitimate traffic during an attack. Cloudflare's systems also automatically detect and respond to DDoS attacks, and provide real-time monitoring and reporting. Additionally, the service offers advanced DDoS mitigation techniques.
Overall, Cloudflare is considered to be a good option for DDoS protection, as it offers a wide range of features and has a proven track record of effectively mitigating DDoS attacks. However, it is important to note that no DDoS protection service can guarantee 100% protection against all attacks, and it is important to have a plan in place for responding to an attack.

Does Cloudflare DNS stop DDoS?
Cloudflare DNS can be a useful tool for mitigating DDoS attacks, but it is not a standalone solution for stopping DDoS. Cloudflare's DNS service, called Cloudflare DNS, is a recursive resolver that can be used to improve the performance and security of a client's DNS infrastructure. By routing DNS queries through Cloudflare's global network of data centers, Cloudflare DNS can help to improve the performance and availability of a client's website.
However, DDoS attacks typically target the application or network layer, not the DNS layer. While Cloudflare's DNS service can help to improve the performance and security of a client's DNS infrastructure, it is not specifically designed to stop DDoS attacks. To fully protect against DDoS, Cloudflare offers a DDoS protection service, which routes traffic through its global network of data centers, automatically detects and responds to DDoS attacks, and provides advanced DDoS mitigation techniques.
Cloudflare DDos Protection Pricing
Cloudflare's DDoS protection service is offered as part of its paid plans, which vary in price depending on the specific features and level of service needed. The prices can be different based on the size of the website and traffic.
The pricing model for Cloudflare DDoS protection is based on the amount of traffic that is protected and the level of protection required.
