How To Protect Your Dedicated Server From DDoS Attack?

Distributed Denial of Service (DDoS) attacks are a common and significant threat to online businesses and organizations. These attacks occur when a large number of devices are used to flood a server with requests, causing it to become overwhelmed and inaccessible to legitimate users.

DDoS attacks can be devastating to businesses, leading to lost revenue, damage to reputation, and disruption of operations. Therefore, it is crucial to take steps to protect your dedicated server from DDoS attacks.

In this article, Anti-Dos will show you  how to protect against DDoS attacks so your server can continue to entertain user requests.

How To Protect Your DDoS Server From DDoS Attack?

Wondering how to protect against DDoS attacks so your servers continue to function as normal?

1. Hire a DDoS Protection Service:

The first and most important step to protect your dedicated server from DDoS attacks is to take advantage of DDoS protection services. DDoS protection services are specialized services that can detect and mitigate DDoS attacks in real-time. These services use advanced techniques such as traffic filtering, rate limiting, and blacklisting to prevent malicious traffic from reaching your server. There are several DDoS protection services available in the market, such as Anti-Dos, Akamai, and Arbor Networks. These services can be implemented on your dedicated server by configuring DNS settings or using a dedicated hardware appliance.

2. Configure Firewall Rules:

Hiring a DDoS protection service provider is not enough. So, how to protect from DDoS attacks? By configuring firewall rules. Firewall rules can be used to block traffic from specific IP addresses, block traffic from specific ports, or limit the number of connections from a single IP address. By configuring firewall rules, you can prevent attackers from accessing your server and reduce the impact of DDoS attacks. Firewall rules can be configured using built-in server firewalls or third-party firewall software.

3. Use Content Delivery Networks (CDNs):

Content Delivery Networks (CDNs) are distributed networks of servers that can cache and deliver content from your server to users around the world. By using CDNs, you can distribute the load of requests across multiple servers, reducing the impact of DDoS attacks. CDNs can also provide DDoS protection, which can detect and mitigate attacks in real-time. There are several CDNs available in the market, such as Cloudflare, Akamai, and Amazon CloudFront.

4. Monitor Network Traffic:

It is crucial to monitor network traffic to detect and prevent DDoS attacks. By monitoring network traffic, you can identify patterns of traffic that may indicate an attack is in progress. You can use network monitoring software, such as Nagios, Zabbix, or PRTG, to monitor network traffic and detect anomalies. If you detect an attack, you can take immediate action to mitigate the attack and prevent damage to your server.

5. Keep Software Updated:

Are you wondering how to protect from DDoS attacks by keeping the software updated? DDoS attackers often exploit vulnerabilities in software to launch attacks. By keeping your server software updated, you can ensure that any known vulnerabilities are patched, reducing the risk of DDoS attacks. You should regularly update your operating system, server software, and applications to ensure that your server is protected against the latest threats.

6. Use Strong Passwords:

Using strong passwords is an important step to protect your server from DDoS attacks. Weak passwords can be easily guessed by attackers, allowing them to gain access to your server and launch attacks. You should use strong, unique passwords for all user accounts on your server, including the root account. You can also use two-factor authentication (2FA) to add an extra layer of security to your server.

7. Limit Resource Usage:

You can limit the amount of resources that each user or IP address can use on your server. By limiting resource usage, you can prevent attackers from overwhelming your server with a large number of requests. You can use tools like cPanel, Plesk, or WHM to set resource usage limits on your server.

8. Use Anti-DDoS Hardware:

You can use dedicated hardware appliances to protect your server from DDoS attacks. These appliances are designed to detect and mitigate DDoS attacks in real-time, preventing them from reaching your server. Anti-DDoS hardware is especially useful for high-traffic websites and businesses that are frequently targeted by attackers.

9. Use IP Whitelisting:

You can use IP whitelisting to restrict access to your server to only trusted IP addresses. By using IP whitelisting, you can prevent attackers from accessing your server and launching DDoS attacks. You can configure IP whitelisting using firewall rules or third-party security software.

10. Plan for DDoS Attacks:

Finally, you should have a plan in place to respond to DDoS attacks. This plan should include procedures for detection, DDoS mitigation and recovering from DDoS attacks. You should also test your plan regularly to ensure its effectiveness.


Protecting your dedicated server from DDoS attacks is critical for the security and availability of your website or business. By implementing a multi-layered approach that includes DDoS protection services, firewall rules, CDNs, network monitoring, software updates, strong passwords, resource usage limits, anti-DDoS hardware, IP whitelisting, and DDoS attack planning, you can significantly reduce the risk of DDoS attacks.

It is also important to stay informed about the latest DDoS attack techniques and trends, as attackers are constantly evolving their tactics. By following these best practices, you can ensure that your dedicated server is well-protected against DDoS attacks.
