SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires blake3, xxhash, zstd, zlib, and includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill provides a comprehensive guide to securing a low-footprint, long-lived MMORPG server against various online threats, such as DoS attacks, protocol abuse, player-on-player flooding, credential brute-force, and information leaks.

Core Features & Use Cases

  • Security Doctrine: Offers a set of best practices and guidelines for implementing robust security measures without requiring a large security team or bloating the binary.
  • Attack Surface Analysis: Identifies the protocol parser as the single entry point for remote input, ensuring no remote packet can crash or hang the server.
  • Layered Rate Limiting: Implements rate limiting directly within the read path, ensuring DoS resilience without compromising performance.

Quick Start

To start applying the security doctrine to your MMORPG server, refer to the guide in the 'security' directory for detailed instructions on implementing each aspect of the security measures.

FAQPage Schema
How do I secure an MMORPG server against crashes from untrusted client inputs?

To secure an MMORPG server against crashes, you must harden the protocol parser as the single entry point for remote input. This ensures no remote packet can crash, hang, or corrupt the server by validating all incoming data.

What is the best way to implement rate limiting in a low-footprint game server?

The best way to implement rate limiting for a low-footprint server is directly within the read path. This layered approach ensures DoS resilience against player flooding and credential brute-force without compromising server performance or bloating the binary.

Do I need C++11 or newer to harden my MMORPG server against DoS attacks?

Yes, hardening an MMORPG server against DoS attacks requires C++11 through C++23. You also need various libraries like blake3, xxhash, zstd, and zlib to implement the necessary memory safety, hashing, and cryptography features.

How does protocol analysis prevent information leaks in a low-footprint server?

Protocol analysis prevents information leaks by treating the protocol parser as the single attack surface. By focusing security doctrine on this entry point, the server mitigates protocol abuse and blocks untrusted client inputs from causing data corruption or hangs.

Why does my MMORPG server hang during player-on-player flooding?

An MMORPG server hangs during player-on-player flooding because it lacks layered rate limiting within the read path. Implementing robust rate limiting directly in the data processing pipeline prevents DoS conditions without requiring a large security team.

Can I secure an MMORPG server without bloating the binary or needing a security team?

Yes, you can secure an MMORPG server without binary bloat or a large security team by applying a specialized security doctrine. It focuses on memory safety and attack surface analysis to prevent credential brute-force and information leaks efficiently.
