How to Prevent DDoS Attacks on Your VPS-Hosted Website


Multiple compromised computer systems will assault targets like as websites, servers, or any other network resource in a Distributed Denial of Service attack. Users of the above-mentioned targeted resources experience a denial of service as a result of these attacks. They work by flooding the target with connection requests, malformed packets, and incoming messages, which causes the target to slow down, crash, or even shut down. As a result, users are unable to use the target.

How can you defend your VPS-hosted website against cyber-attacks?

1. A DDoS protected VPS

VPS with DDoS mitigation is referred to as a DDoS protected VPS. It’s also known as a ‘Anti DDoS VPS,’ referring to the fact that it’s hosted on a server that’s protected from DDoS attacks. A DDoS-protected VPS must have a large data transmission limit as well as strong firewalls, which should stop any attack in its tracks before it can cause any damage. It will protect your website from volumetric attacks, protocol-based attacks, as well as attacks on single servers or user applications.

2. Make a strategy

You don’t have to wait for a DDoS attack to intervene. Anticipating what might happen and taking preventative actions is half the battle fought. Setting up sensors to notify you when your website is down, dumping logs quickly, acquiring DDoS protection tools, and contacting your ISP to learn about your free and paid DDoS choices can all assist to mitigate the risk. Remember that being forewarned is being forearmed.

3. More resources should be kept on hand

Give your website plenty of network bandwidth. In the event of an attack, over-allocating resources such as bandwidth will provide your site a brief window of time. You can save time by verifying that the extra network capacity you’ve set aside can handle the unexpected spike in traffic.

4. Firewall

You must configure your firewall correctly in order to get a DDoS-protected VPS. Furthermore, you must actively use your firewall. A firewall will close all ports except HTTP, HTTPS, and SSH, leaving only HTTP, HTTPS, and SSH open.

5. Keep Up to Date

Using open-source platforms like WordPress necessitates vigilance, particularly when it comes to updating them. If you are, the security flaw has been closed. If there is a time delay between the update and the application, your system will be vulnerable to attack during that time period.
