DDoS Attacks: Defense Methods for Large and Small Scale Attacks

In the vast ocean of the internet, DDoS (Distributed Denial of Service) attacks are like an invisible storm, constantly threatening our network security. Whether targeting large enterprises or small websites, DDoS attacks can affect anyone. Therefore, understanding and mastering defense methods against DDoS attacks is crucial for safeguarding our cyberspace. This article will explore the principles of DDoS attacks, their classifications, and the defense strategies for both large-scale and small-scale attacks, incorporating Goooood® DDoS/CC Mitigation and SafeCDN products to provide a comprehensive guide.

2. Overview of DDoS Attacks

A DDoS attack is a method where attackers use a large number of legitimate or illegally controlled computer resources to send a massive number of requests to a target server, rendering it unable to process regular user requests. Attackers typically employ techniques such as traffic flooding and protocol exploitation to exhaust the server’s resources, making the service unavailable. DDoS attacks do not only target large enterprises; they can also be directed at small websites and even individual users.

The Goooood® Global DDoS Protection Service offers real-time defense against such attack types by employing sophisticated traffic scrubbing, real-time monitoring, and a distributed network architecture to ensure that businesses and individual users can maintain normal operations even when under DDoS attacks.

3. Classifications of DDoS Attacks

1. Traffic Flooding Attacks: Attackers generate a massive number of invalid requests to overwhelm the server, preventing it from processing legitimate user requests.
2. Protocol Attacks: These exploit vulnerabilities in network protocols to attack the target server, such as SYN Flood or ACK Flood attacks.
3. Hybrid Attacks: Combining both traffic flooding and protocol attacks, attackers launch multiple types of assaults on the target server simultaneously.

4. Defense Methods for Large Scale Attacks

For large enterprises or critical websites, defense strategies must be comprehensive and in-depth. Goooood® DDoS/CC Mitigation provides a robust multi-layer defense system tailored for high-risk targets.

1. Deploy High-Defense IPs: Goooood®’s High-Defense IP Service redirects large volumes of malicious traffic to high-defense IP nodes, absorbing the impact and reducing the load on the primary server. This is particularly important for banks, e-commerce platforms, and other businesses that require high availability.
2. Traffic Scrubbing and Filtering: Goooood®’s Traffic Scrubbing System performs real-time monitoring and filtering of network traffic, automatically identifying and removing invalid requests and malicious traffic. This layer of defense significantly reduces the impact of traffic surges caused by DDoS attacks.
3. Distributed Defense Architecture: Goooood® SafeCDN uses a distributed network architecture to deploy services across multiple geographical regions and nodes, dispersing the attack load and ensuring that no single node is overwhelmed. This approach also improves user access speeds and enhances overall experience.
4. Regular Updates and Patching: Regular updates to system and software security are essential in the face of evolving DDoS attacks. Goooood® encourages businesses to periodically check for system vulnerabilities and apply patches to reduce the risk of exploitation.
5. Establish a Security Team: Large enterprises should establish a dedicated security team to monitor network security events in real-time, quickly identify and mitigate DDoS attacks. When combined with Goooood® DDoS Mitigation, security teams can respond more efficiently to attacks.

5. Defense Methods for Small Scale Attacks

For small websites and individual users with limited resources, while they may lack the infrastructure of large enterprises, there are still several methods to minimize the impact of DDoS attacks:

1. Use CDN Acceleration: Goooood® SafeCDN distributes website traffic across global CDN nodes, alleviating the load on the primary server. This is particularly useful for small websites or blogs. In addition to improving load times, Goooood®’s CDN can also defend against small-scale DDoS attacks.
2. Limit Concurrent Connections: Setting appropriate limits on concurrent connections can effectively prevent low-intensity traffic flooding attacks, ensuring the server remains operational.
3. Regular Data Backups: Although backups cannot directly defend against DDoS attacks, they can reduce the risk of data loss in the event of a severe attack by allowing a quick recovery of data.
4. Enable Firewalls and Intrusion Detection Systems: Goooood® Web Application Firewall (WAF) provides an extra layer of protection for small websites by blocking malicious requests and preventing unauthorized access. Even for those with limited resources, WAF is a cost-effective security measure.
5. Choose Reliable Service Providers: For small businesses or personal websites, selecting a reputable hosting provider with strong DDoS protection services is essential. Goooood® SafeCDN and DDoS Protection Services offer all-in-one security solutions that help smaller websites handle sudden attacks.

6. Conclusion

Both large enterprises and small websites are at risk of DDoS attacks. By deploying Goooood® High-Defense IP, traffic scrubbing and filtering, and distributed defense architectures, businesses can effectively mitigate the risks of DDoS attacks and ensure the continuity and stability of their online services. Additionally, for smaller websites or individual users, Goooood® SafeCDN, WAF, and DDoS mitigation services provide powerful protection. No matter the scale of the attack, Goooood® is committed to offering efficient security solutions to various industries, helping users maintain competitiveness and security in an increasingly complex digital environment. Together, we can protect the internet and embrace a safer future.
