OWASP Game Security Framework (GSF)

The OWASP Game Security Framework (GSF) represents a modular approach to understanding the security issues that surround video game ecosystems.

In 2016 the videogame market became 99.6 Billion dollar industry... any why shouldn't it be? Some of the most prolific and complex software developed today are video games. They are professionally played, sponsored, scrutinized, monetized, and celebrated, just like many sports. They handle clients, servers, web components, monetary transfers, social interactions, virtual markets, etc, with every bit the need of security that most internet hosted apps have (if not more in some cases). The GSF is designed to help threat model gaming issues that have devastated new games. Most importantly we hope the GSF can help new developers and security testers alike root out bugs in your favorite titles.

The framework is broken into three main concepts / sections:

1. Identifying and clustering the components of risk within the overall game security space, and then giving instances of each component.

Components include the following:

Attack Surfaces: the various surface areas that can be attacked by attackers in order to cause harm to the gaming ecosystem.

Vulnerabilities: the specific weaknesses in design or implementation that allows attackers to successfully target a given game.

Attacker Goals: a list of the reasons that an attacker might want to attack a given game.

Negative Outcomes: a collection of ways that the gaming company could ultimately be impacted negatively by attacks to its game and associated infrastructure.

2. A natural language semantic structure for thinking about and articulating game security issues, which uses the modular risk components as sentence structure.

Example:

"The attacker attacked and edited the LOCAL GAME CLIENT (Attack Surface), which had a LACK OF CLIENT INTEGRITY CONTROLS (Vulnerability), which allowed her to ARTIFICIALLY INCREASE HER ABILITIES (Attacker Goal), ultimately leading to an UNHAPPY PLAYER BASE (Negative Outcome) and DECLINING GAME REVENUE (Negative Outcome) due to cheating.”

Using this structure, security testers can clearly communicate the various aspects of a game security issue to many different types of stakeholder—from pentesting peers to business executives in the gaming industry.

3. Examples of real-world examples of previous attacks against games, and how the attacks map to the GSF framework components.

What is the OWASP Game Security Framework?

The goal of the OWASP Game Security Framework is to provide a structure for discussing the various aspects around the security of video games.

The target audience for the project includes:

Gamers
QA
Game designers
Penetration testers
Gaming executives
Anyone else with a vested interest in game security

-The following is a list of the vulnerabilities that can be found in video games of various types, and the attack surfaces they're likely to be associated with.
+This list refers to what a given attacker might be trying to accomplish within the game by performing a given attack. This could relate very closely (or not) with the technical impact or business impact cause by the behavior.
