Welcome to the Secure Design Principles for Software Development. This guide is designed to give developers a practical and easy-to-implement blueprint to jumpstart secure software development practices. By focusing on key principles, developers can mitigate a significant number of vulnerabilities, including those related to injection and IDOR (Insecure Direct Object References).
This repository provides a structured guide on key secure design principles, including whitelisting, type checking, length checking, threat modeling, and addressing authorization flaws. Each section is crafted to be straightforward, providing developers with clear guidance on how to integrate these practices into their coding processes effectively.
Learn how to implement effective whitelisting mechanisms in your applications, which are crucial for controlling what types of inputs or behaviors are permitted, thereby reducing the risk of unwanted or malicious data processing.
Understand the importance of type checking in your code to prevent type-related errors and vulnerabilities, particularly those that can be exploited through injection attacks.
Discover how to implement length checking to ensure that inputs do not exceed expected bounds, which can protect your applications from various forms of overflow attacks.
Explore basic threat modeling practices to systematically analyze the security of your applications. This section helps you identify potential security issues before they can be exploited.
Gain insights into common authorization flaws like IDOR, and learn strategies to ensure robust authorization checks that confirm a user’s rights to access or modify resources.
Learn how output encoding can prevent Cross-Site Scripting (XSS) vulnerabilities by ensuring that user-controlled data is safely rendered in various browser contexts (HTML, attributes, JavaScript, CSS, and URLs). This section provides guidance on proper encoding practices depending on where untrusted data ends up in the page, and how defenses like CSP (Content Security Policy) and sandboxing can enhance protection.
This guide is specifically crafted for:
- Developers: Focused on those new to security or looking to enhance their understanding of secure coding practices.
- Security Champions: Developers who are tasked with leading security initiatives within their teams.
We encourage contributions that add value to this guide, particularly practical examples and enhancements on secure coding practices. Please contribute through pull requests or issues. Access and contribute to the repository HERE.
