Dedicated servers play an important role in hosting services for websites, applications, and businesses. However, with the increasing cyber threats, ensuring the security of these servers has become paramount. 

One of the most significant threats faced by dedicated servers is Distributed Denial of Service (DDoS) attacks. In this article, we’ll explore what DDoS attacks are, the importance of DDoS-protected dedicated servers, and how they can safeguard your online presence.

What is a DDoS Attack?

A Distributed Denial of Service attack is a harmful attempt to disrupt the functioning of a targeted, dedicated server

These attacks overwhelm the server infrastructure with a flood of internet traffic, which causes the server to slow down significantly. DDoS attacks are successful because they use compromised or unprotected computers and servers as sources of attack traffic.

To put it simply, a DDoS attack is like an unexpected traffic jam caused by fake users, preventing legitimate users from accessing your website or application.

Signs of a DDoS Attack

It’s essential to identify the signs of a DDoS attack to take prompt action. Some common symptoms include:

  • Sudden website or application unavailability or extreme slowness.
  • Suspicious large traffic coming from a single IP address or range.
  • A flood of traffic from users sharing a similar behavioral profile, such as device type, web browser version, or geolocation.
  • Odd traffic spikes or patterns, like unexpected traffic at unusual hours or unnatural patterns.

Mechanisms of DDoS Protection

Several countermeasures have been adopted and are continuously evolving to protect dedicated hosting servers from DDoS attacks. These attacks are often caused by intruders attempting unauthorized access to the victim’s dedicated server. Some common DDoS protection dedicated server mechanisms include:

  1. Prevention Techniques

These techniques aim to prevent DDoS attacks before they occur. Examples include ingress filtering, egress filtering, route-based distributed packet filtering, secure overlay services, applying security patches, changing IP addresses, disabling IP broadcasts, disabling unused services, load balancing, and honeypots.

  1. Detection Techniques

These techniques help identify and avoid the spread of DDoS attacks, preventing server crashes. Common methods include anomaly detection, running scalable network monitoring systems, packet sampling and filtering techniques, and using data structures designed to detect and prevent DDoS attacks.

  1. Response to Detection

If your dedicated server is under a DDoS attack, the next step is to block the attack and trace the attacker’s identity. This can be done manually using Access Control Lists (ACLs) or automatically through specialized software.

Instances Where DDoS-Protected Dedicated Servers are Crucial

Dedicated server hosting with DDoS protection is essential for various types of servers and websites due to the potential impact of DDoS attacks:

  1. Gaming Servers: Online gaming servers with large user communities are common targets for DDoS attacks.
  2. E-commerce Servers: DDoS attacks on e-commerce servers can cause significant downtime, preventing customers from accessing and purchasing products leading to revenue losses.
  3. Online Banking Servers: These servers handle sensitive financial information, and a DDoS attack can prevent customers from accessing their funds.
  4. SaaS Application Servers: Software-as-a-Service (SaaS) businesses rely heavily on their hosted applications, and DDoS attacks can result in downtime, loss of customers, and revenue losses.
  5. Email Servers: Professional businesses often use dedicated email servers, which are prone to DDoS attacks, which can potentially disrupt communication. 

Conclusion

DDoS attacks pose a severe threat to dedicated servers and can have devastating consequences for businesses. 

By understanding the nature of these attacks and implementing the best DDoS-protected dedicated servers, you can safeguard your website, applications, and online presence.
