In this article, we zoom in on security and uptime – everything that ensures your game server stays online and protected. You'll get specific tips on how VPS hosting can help you avoid downtime, protect against attacks, and create security around your server so you can focus on the game without worries.

Why are security and uptime crucial for your game server?

Stability and security are just as important as high FPS when it comes to online gaming. If your server suddenly goes down or is attacked, you risk frustrated players and lost momentum. In fact, nearly 36% of all DDoS attacks in 2019 were directed at the gaming industry (Online Gaming DDoS Attacks | How Dedicated Server Hosting Can Help). In other words, game servers are a favorite target for malicious attacks.

Imagine the consequences: in the middle of an intense Minecraft session, everyone loses their connection because someone floods your server with traffic, or a hacker exploits a vulnerability and destroys your data. Without the right security measures in place, months of work—from carefully constructed worlds to players' personal progress—can be lost in an instant. For a community around a CS:GO or ARK server, repeated crashes or security issues can mean that players won't bother coming back. In short, a secure and stable server is the foundation of a good gaming experience.

The biggest threats to your game server

What can actually threaten the stability and security of your game server? Here are some of the typical risks you should be aware of:

• DDoS attacks: A DDoS (Distributed Denial of Service) attack can cripple your server by flooding it with fake traffic. In the gaming world, this unfortunately happens often – for example, if a frustrated opponent wants to sabotage the game. The result is high latency or total downtime for your real players until the attack stops.
• Hacking and exploitation of vulnerabilities: Outdated server software or weak passwords can give hackers free rein. They can gain unauthorized access, steal administrator rights, or inject malware. For you, this can mean anything from destroyed game data to unauthorized persons gaining control of your server.
• Data loss due to crashes: Hardware failure, software crashes, or human error can cause your game server to go down. If you don't have a backup, such a crash can mean permanent loss of progress—think of a Minecraft world disappearing or a Rust server where all buildings are reset. Without a recovery plan, even short-term outages can have long-term consequences.

As a server owner, you should always keep these threats in mind. Fortunately, with the right measures and choice of hosting, you can significantly minimize the risk.

How VPS hosting protects your server

A Virtual Private Server (VPS) can make a big difference to the security and stability of your game server. Where regular game hosting may give you limited options, a VPS offers a higher level of control and protection. Here are some ways in which VPS hosting provides extra security and uptime:

• Isolated server environment: With a VPS, you have your own server environment, isolated from other customers. Unlike shared hosting, you don't share resources with strangers – so your neighbor's security problem isn't your problem. This isolation also means that your server runs stably without outside interference, and vulnerabilities on other machines on the same physical machine cannot be exploited against you.
• Network with DDoS protection: The best VPS providers have built-in DDoS protection at the network level. This means that malicious traffic is filtered out before it hits your game server. At PineRiver, for example, DDoS protection is included automatically, so you can game without interruptions. This drastically reduces the risk of downtime, even if your server is attacked.
• Full control over security: Because you get root access on a VPS, you can customize the security yourself. You can install firewall software of your choice, configure exactly which ports may be open, and keep the operating system up to date without being dependent on an external host's default settings. In short, you have the freedom to harden your server so that it is difficult to break into.
• High uptime and reliable infrastructure: VPS servers typically run on robust hardware in professional data centers. This means redundant power supplies, cooling, and network connections—everything that ensures stable operation. Many VPS providers even offer uptime guarantees (e.g., 99.9% uptime), which reflects a high degree of reliability. Your game server gets dedicated resources so it doesn't crash because others suddenly use it all. And if disaster strikes, the provider often monitors the systems 24/7 so that problems can be solved before they affect you and your players.

In other words, a good VPS lays the foundation for secure operation. But there are also things you, as a server administrator, should do yourself. The next section gives you five specific tips to further enhance security.

5 tips for securing your game server on a VPS

Although a VPS gives you a solid starting point, a secure game server also requires active maintenance on your part. Here are five important tips:

1. Keep the server updated: Always make sure to install the latest updates for both your server software (the game) and the server's operating system. Updates close known security holes – for example, a new Minecraft server version can patch a duplication bug, or a TeamSpeak update can fix an exploit. By keeping the system up to date, you make life difficult for hackers who exploit old vulnerabilities.
2. Set up a firewall: A firewall filters traffic and can block unwanted connections. On a VPS, you can use ufw or firewalld (on Linux) or Windows Firewall to only allow the ports your game server needs. Close everything else. For example, if your game runs on port 25565 (Minecraft) or 27015 (Steam games), only leave that port open. This reduces the risk of unauthorized persons gaining access to the server via other services.
3. Use strong passwords and 2FA: Protect all access points with unique, complex passwords – whether it's SSH/Remote Desktop to the VPS itself or a web-based control panel. Avoid default logins and simple codes such as "123456" or "password". Enable two-factor authentication (2FA) where possible, so that even if a password is leaked, unauthorized persons cannot log in without the additional one-time code.
4. Take advantage of DDoS protection: Check that your VPS provider's DDoS protection is active for your server. With some providers, you may need to enable it yourself via the control panel – with others, such as PineRiver, it runs automatically. If your provider does not offer DDoS protection, you should strongly consider switching or adding an external solution. You can also monitor traffic to your server; a sudden spike may indicate an attack, and then it is important to react quickly (e.g., temporarily change your IP via a proxy service or contact your provider).
5. Take regular backups: No system is 100% fail-safe, so backups are your last line of defense. Schedule automatic backups of your VPS or at least the game data itself (world files, configuration files, databases, etc.) at regular intervals—daily or weekly, depending on activity. Many VPS providers (including PineRiver) offer built-in backup solutions or snapshots; take advantage of them! And most importantly: test your backups from time to time to make sure they can actually be restored. A backup is worth its weight in gold when an update goes wrong or a misconfiguration deletes something important.

These five measures will significantly strengthen your server's defenses. You reduce the surface area for attacks and have a plan B ready if disaster strikes.
