DDoS attack, also known as denial of service attack, is simply understood as creating massive access to one website address at a time. This is intended to “crash” the hosting server, causing it to load slowly or become unresponsive to users. The following article will share the most effective anti-DDoS methods to help website owners be proactive in website security activities.
What is DDoS?
DDoS stands for Distributed Denial of Service, it means distributed denial of service. It can be understood simply that these are attacks with the aim of stopping the activities of a certain website, making users unable to access the hacked websites.
DDoS attack not only causes bad effects on the website being attacked but also interferes with users when they need to access it.
There are three basic types of DDoS attacks:
DDoS attack on Application layer (application): this type of attack mainly targets websites and web applications.
Protocol (protocol) DDoS attack: this type of attack is mainly about exploiting server resources
DDoS attack with Volume-based (based on large hacker infrastructure): flood the network bandwidth by using high traffic.
Hackers often target the websites or applications of organizations such as banks, credit card payment gateways, and even DNS root servers.
What anti-DDoS is effective for website owners?
- Using broadband infrastructure
The first and most important thing that you can do is make sure that your web host has more bandwidth than is necessary. Register to rent a broadband VPS at reputable providers. This is especially useful because it helps the webserver to be able to handle the spike in traffic. Besides, you can also extend the time to promptly respond, or handle larger and more sophisticated DDoS attacks.
- Contact your web host provider
You should contact your web host provider and ask for help, informing them that the website is under attack. While they may have detected the attack, it may well have been too large for them to handle. You should choose to use website hosting services at hosting providers that provide other support services such as CDN and WAF services. CDN helps to solve the infrastructure DDoS part (Layer 3/4) and WAF will prevent DDoS attacks on websites and applications (Layer 7).
- You need a team of experts to support you when you are frequently hit by DDoS
Most DDoS attacks are short-lived. Therefore, if your website is not too important or the revenue does not come from the website, a few minutes or a few hours of downtime will not affect the brand reputation or the revenue of the company much. However, if the website is the brand face of the organization or the revenue of the business mainly comes from the website, then you need to protect it every minute and every second.
Hackers often target large organizations to carry out regular DDoS attacks, aiming to bring down brand reputation or demand ransom. In these cases, you must have a team of experts to support network security monitoring at the SOC - Security Operation Center rooms.
How to fight DDoS for Game Server
While the majority of DDoS attacks can be avoided, taking steps to protect yourself as an individual player is very different from protecting the entire network.
If you are trying to protect a network or a gaming website, the most important aspect to consider is your hosting provider (Cloud VPS) and their firewall (Web Application Firewall). While this is not a comprehensive solution, it is an effective way to block simple DDoS attacks. The best way to fight DDoS for Game Server is to detect it early.
As for gamers, the first thing you should do is develop guidelines like: Do not open spam emails or download software from poor quality websites, it may contain malware that sends your IP address. you for a hacker. Second, you should use anti-virus software or anti-malware software. The third thing is that you can use a VPN (a virtual private network).
The VPN will route your connection through their servers and give you a new IP address that masks your real one. However, if the hacker has already scanned your IP address, the VPN won’t be able to do anything anymore. Also, using a VPN has the potential to cause lag for gamers.
The most important thing you need to remember is to use anti-virus software and be careful what you click on online. Antivirus software will help if you accidentally download malware that could compromise your IP address, but you should still be careful what you download and click on.

How to implement Anti-DDoS VPS effectively?
There are 6 ways to implement Anti DDoS VPS as follows:
Use DDoS Protected VPS: This is a VPS that includes DDoS Mitigation. It is also known as ‘Anti DDoS VPS’, which means it resides on a server that is protected from DDoS attacks. A DDoS-protected VPS requires high data transmission capacity and a solid firewall. It will keep your website protected from large traffic DDoS attacks, protocol-based attacks, and attacks on web servers or applications.
Monitor traffic to your VPS: You need to regularly monitor the traffic on your website, to know clearly whether your website is under attack or not. Early detection of traffic spikes. Also, keep in mind that: traffic will increase after advertising campaigns or during events and promotions. Once you know the level of traffic to your website, DDoS anomalies occurring on your VPS will also be easily recognizable. In addition, DDoS attacks will also often occur at the most sensitive times (when traffic from real users is high) that will most likely cause damage to VPS. Therefore, be cautious during promotions or times of big events.
Prepare Anti DDoS Activity Plan: Be prepared before a DDoS attack actually happens. You will be sure to win in the process of implementing Anti DDoS for VPS. Using continuous network security monitoring measures (SOC room) will help prevent DDoS attacks early or use advanced anti-DDoS services.
Ensure maximum availability of scalability resources for VPS: Allocating excess bandwidth resources to VPS will make it responsive while waiting for the expert team to handle the case being attacked.
Configure your VPS firewall correctly: In order for your VPS to be protected from DDoS, you need to configure your firewall correctly. Furthermore, you need to use the firewall proactively. The firewall will close all ports, leaving only HTTP, HTTPS, and SSH ports open.
Keep your web platform up to date to protect your VPS: Using open-source platforms like WordPress means you need to be vigilant – especially when installing updates. Need to make sure the security holes have been filled. However, if there is a delay between the update and the application, your system will remain vulnerable during that time.
The best way to effectively Anti DDoS is to choose a reliable VPS hosting provider. Good VPS providers will be able to assist you with a team of experts that are always available should you need them.
