Understanding the Threats: What Game Servers Face 3 Types of DDoS Attacks A Distributed Denial of Service (DDoS) attack is a critical threat to the stability and accessibility of game servers. In gaming, where real-time performance and low ping are crucial, these attacks can render a gaming server virtually unusable. Here are the most common types of DDoS attacks encountered by servers:
Volume-Based Attacks: These attacks aim to overwhelm the network bandwidth. Whether it’s a Minecraft server hosting setup or a more extensive network for games like 7 Days to Die or Valheim, the influx of bogus traffic is immense, making legitimate game traffic unable to process.Protocol Attacks include Ping of Death and Smurf DDoS, which exploit vulnerabilities in the server’s transport and internet protocols, saturating them with requests and causing significant disruption.Application Layer Attacks: These attacks target the very part of the server where web pages are generated and HTTP requests are processed. They are sophisticated enough to disrupt the server without significant traffic. Common Hacking Techniques Beyond DDoS attacks, game servers are vulnerable to hacking techniques that compromise server security, steal user data, and interrupt gameplay. Here are some prevalent methods:
SQL Injection: Hackers use SQL injection to manipulate server database queries through the game’s website or backend database. This can allow attackers to access the server files, jeopardize the integrity of a game, and even manipulate in-game elements.Cross-Site Scripting (XSS): Through XSS, attackers inject malicious scripts into the web pages viewed by users or the server control panel.Phishing Attacks : Server administrators and players can be deceived into providing login credentials through counterfeit websites mimicking popular hosting platforms. This technique can lead to unauthorized access to the server management tools and sensitive player information.Cross-Site Scripting (XSS): By injecting malicious scripts into a game or its forums, hackers can hijack user sessions, deface websites, or redirect players to malicious websites.Zero-Day Exploits: These attacks take advantage of previously unknown vulnerabilities in the game server software that have not yet been patched. They are particularly dangerous because there is no known defense against them until the vulnerability is discovered and fixed.Man-in-the-Middle (MitM) Attacks: In these attacks, the hacker intercepts the communication between the player and the game server to steal login credentials, manipulate game data, or eavesdrop on sensitive information.Exploitation of Software Vulnerabilities: Hackers exploit bugs or vulnerabilities in the game server’s software to gain unauthorized access or cause disruptions. This could include buffer overflows, SQL injection, or exploiting outdated software. 1. Initial Steps to Secure Your Game Server Source: Canva Pro

2. Setting Up Firewalls and DDoS Protection Choose the Right Firewall Hardware or Software The first step in setting up firewall protection for your game server is choosing the right type of firewall. There are two main types of firewalls: hardware and software.
Hardware Firewalls are physical devices placed between your server and the Internet. They are particularly effective in filtering out unwanted traffic before it reaches the server.Software Firewalls : These are installed directly on the server and offer more customizable protection settings. Software firewalls can be finely tuned for game servers to allow specific game-related traffic while blocking potentially harmful data. Configure Firewall Rules Once you have your firewall, you must configure the rules to determine what traffic can pass through to your game server.
Allow Game-Specific Traffic : Identify and allow ports your specific game needs to function. For example, if you’re hosting a server for “ARK: Survival Evolved,” you’ll need to open the ports that ARK uses for incoming and outgoing traffic.Block Unnecessary Ports : Close all ports not used by your game or necessary for server operations. This minimizes the number of entry points for potential attacks.Set Up Intrusion Detection Systems (IDS) : These systems monitor network traffic for suspicious activity and can be integrated with your firewall to enhance security. Implement DDoS Protection Solutions DDoS attacks involve overwhelming a server with traffic, making the game slow or completely unresponsive. To protect against these:
Use a DDoS Protection Service : Many game server hosting providers offer DDoS protection as part of their service. These services typically involve sophisticated filtering techniques that detect and block traffic surges that could indicate a DDoS attack.Consider Cloud-Based DDoS Mitigation : Cloud-based solutions can absorb malicious traffic before it reaches your server by spreading the traffic across a global network of servers. Regularly Update Your Security Measures Cyber threats are constantly evolving, so it’s essential to keep your security measures up to date:
Keep Your Firewall and Server Software Updated : Regular updates often include security patches that protect against new vulnerabilities.Review and Update Firewall Rules Regularly : The network requirements may change as new games are released or updates are applied to existing games. Regularly reviewing and updating your firewall rules ensures that only legitimate traffic reaches your server. Monitor and Test Your Firewall and DDoD Protection Regular monitoring and testing can help you understand how your security measures stand up to potential threats:
Conduct Regular Security Audits : Regular audits can help identify potential vulnerabilities in your firewall configurations and DDoS protection strategies.Use Monitoring Tools : Implement tools that provide real-time analytics about the traffic coming to and from your server. These tools can help you spot unusual patterns that might indicate an attack. 3. User Authentication and Access Controls Source: Canva Pro
Strong Authentication Methods Implementing robust authentication methods ensures that only authorized users can access your game server. For servers running popular multiplayer games like “ARK: Survival Evolved” or “Rust,” consider using third-party tools that enhance security.
Features like two-factor authentication (2FA), which requires users to provide two forms of identification before access is granted, can significantly enhance your server’s security posture.
This is particularly important for games where players can rent their servers or mod their gaming experience, as it adds a layer of security against unauthorized access.
Managing Access Permissions Properly managing access permissions is essential for maintaining the integrity of your game server. Assign user roles with precision, ensuring that each player or mod creator has access only to the resources necessary for their role.
For example, using a ticket system for admin requests can help maintain control and provide a clear audit trail of actions taken on the server.
This is especially important in environments where multiple mods or custom content, such as “Melodies of the Mire” for “ARK,” are used, as it helps prevent accidental or malicious changes to critical game settings.
4. Data Protection Strategies Protecting data integrity and ensuring privacy is pivotal for any game server, especially when managing sensitive information related to user accounts and in-game transactions.
Regular Backups Secure and frequent backups are essential for recovering data in case of corruption, data loss, or a cyber-attack.
Automate Backup Processes Off-site Storage : Store backup copies in off-site storage solutions or cloud services. This diversification adds an extra layer of security by safeguarding your backups from local hardware failures. Encryption of Sensitive Data Encryption transforms readable data into encoded information that only authorized parties can decode, providing protection for data both at rest and in transit.
Encrypt Data in Transit : Use SSL/TLS protocols to secure all data exchanges between the server and clients, ensuring that data transmitted during gameplay and account transactions remains confidential.Encrypt Data at Rest : Apply strong encryption standards to all stored data, susceptible information such as user IDs, passwords, and personal information. Data Masking and Redaction Protecting personal identifiers and sensitive data during processing and storage is crucial, mainly when data is used for development or testing.
Dynamic Data Masking : Implement masking techniques that obscure sensitive data in real-time as requested, ensuring that unauthorized personnel cannot view or access the actual data.Static Data Masking : Use this technique in non-production environments to create a sanitized version of your data, useful for testing and development without risking actual sensitive data. Monitoring and Auditing Continuous monitoring and thorough auditing are necessary to quickly detect and respond to potential data breaches or irregular activities.
Real-time Monitoring Tools : Deploy monitoring solutions that can detect unusual access patterns or changes to data, alerting administrators to potential threats.Audit Trails : Maintain comprehensive logs of data access and changes. Review these logs regularly to track all interactions with sensitive data, which is critical for both security purposes and compliance with data protection regulations. Regular Vulnerability Assessments Regular assessments help identify and mitigate vulnerabilities before attackers can exploit them.
Security Audits and Penetration Testing : Regularly schedule audits and penetration tests conducted by external security experts.
