DDoS attacks frequently make headline news with some of the top web hosting providers having been targeted in recent years. Luckily, protection is available.
If you have a VPS cloud server, review the following information on DDoS attacks and the steps needed to stay safe.
What Is a DDoS Attack?
DDoS (Distributed Denial of Service) is a type of malicious attack intended to disrupt network traffic. Most DDoS attacks involve a collection of infected devices called bots. Hackers use malware to gain control of computers.
The infected bots are called a botnet. After establishing the botnet, hackers direct it to send requests to specific servers or websites. Depending on the type of DDoS attack, hackers may overwhelm a server with traffic, preventing real users from accessing the site.
The DDoS attack denies service to normal traffic. Common types of DDoS attacks include:
- Protocol attacks
- Volumetric attacks
- Application layer attacks
- DNS amplification attacks
With a protocol attack, hackers cause disruption to normal services by using up all available resources. The attackers target the network layer and transport layer of the Open Systems Interconnection (OSI) model. Your website may receive an overload of spoofed packets, rendering your website inaccessible.
Volumetric attacks attempt to cause network congestion by using all available bandwidth. Instead of sending spoofed packets, the attackers send large amounts of requests to the network. Essentially, the volumetric attack involves a large volume of data to help clog the network.
Application layer attacks target the seventh layer of the OSI model. The application layer is responsible for handling HTTP and SMTP communications, such as when a real visitor reaches your website. With this form of DDoS attacks, attackers use infected bot devices to overload the server with HTTP requests.
DNS amplification attacks rely on open DNS resolvers to overwhelm a server with amplified DNS queries. Attackers spoof the IP address of the target and send multiple requests to the server. The DNS resolver then sends a response from the target to the target, flooding the network with data and denying service to normal traffic.
Those are just a few examples of potential DDoS attacks. Hackers continue to devise new ways to take down computer networks, requiring network security professionals to continue finding ways to combat the threats.
Understanding the Risks of DDoS Attacks
The biggest risk of a DDoS attack is an interruption of services. Your server may shut down due to a sudden surge in traffic, preventing you or anyone else from accessing the server and the applications or webpages that it serves.
Without access to your server, your organization may struggle to complete its daily operations. You may lose access to customer data, sales information, and other vital records.
In severe cases, you may even permanently lose your data. However, a reliable hosting provider should offer backup services to protect against permanent data loss and help restore your server quickly.
How Can You Protect Against DDoS Attacks?
As DDoS attacks involve malicious traffic, you need to monitor the traffic coming to your server. You want visitors to reach your servers while blocking potential hackers. Carefully analyzing incoming traffic requires firewalls and other advanced monitoring solutions, typically provided by a DDoS protection service.
After analyzing the traffic, you need to redirect the bad traffic to keep it away from your server. Without redirection, there is a greater risk of bad traffic crashing your server.
Along with traffic monitoring and routing, you can increase protection by configuring LiteSpeed Web server on your VPS cloud server. Compared to Apache servers, LiteSpeed servers provide superior DDoS protection.
LiteSpeed is designed as a drop-in replacement for Apache servers, making it compatible with 100% of old server software including Apache’s mod_security feature. LiteSpeed adds to the mod_security feature, ensuring that you have additional DDoS protection.
In fact, LiteSpeed outperformed Apache in side-by-side testing of protection against DDoS attacks. In the test, Apache servers were quickly overwhelmed by the attacks and eventually crashed while LiteSpeed servers blocked the attack.
How Do You Get DDoS Attack Protection?
Most enterprises do not have the resources to monitor their own traffic and not all applications require LiteSpeed. To receive protection for your virtual private server, choose a DDoS-protected VPS Hosting.
Some servers come with DDoS protection services. For example, at YottaHost, you get free DDoS protection for standard VPSs. However, DDoS protection for NVMe VPS is an added feature with an additional cost.
YottaHost offers standard VPS servers and NVMe VPS servers. NVMe VPS servers provide many advantages compared to a standard VPS, including faster read/write speeds and the ability to handle heavier workloads. You also have the option of adding superior DDoS protection.
The paid DDoS protection monitors up to 1Mbps of incoming traffic. Cloud VPS hosting solutions include free DDoS protection up to a specific bandwidth limit. An additional fee is added for traffic that exceeds the limit.
DDoS protection requires more than just monitoring. You also need a provider that can help restore your server quickly in the event of a DDoS attack. The company that provides your server should help determine which services were affected and get your server running again.
No matter the type of server, YottaHost has solutions to help protect against DDoS attacks and other cyber threats. DDoS mitigation is included with standard VPS cloud servers, ensuring that everyone has access to reliable protection. To stop worrying about the security of your servers, compare DDoS protected VPS plans from YottaHost.
