Introduction

In 2025, the Sovereign Tech Agency invested in Open Web Docs to enrich developer documentation on web security and privacy. This ambitious project materializes with updated security documents on MDN, providing developers with invaluable resources to navigate the complex world of web security.

Attacks: Understand to Better Defend

The "Attacks" section on MDN presents a series of articles detailing major attack types, from phishing to prototype pollution attacks. Each article describes the conditions of vulnerability and offers practical defenses. For example, Cross-Site Scripting (XSS) is often countered by Content Security Policies (CSP) and strict input validation.

Defenses: Protection Strategies

The documentation on defenses highlights web platform practices and features to protect against attacks. A notable example is the integration of Transport Layer Security (TLS) to ensure data privacy in transit. The defense-in-depth strategy is crucial, combining multiple methods to enhance overall security.

Threat Modeling: Anticipating Risks

Threat modeling helps developers identify potential system vulnerabilities. MDN guides provide practical examples and threat models for modern web applications, assisting developers in choosing the appropriate defenses.

Authentication: Securing Access

Authentication remains a cornerstone of web security. MDN explores various mechanisms, such as federated identity and one-time passwords (OTP). Each method is analyzed for potential vulnerabilities and best practices to adopt.

What's Next

The Sovereign Tech Agency continues its work with Open Web Docs to enrich web privacy documentation. Although this aspect is less extensive than security, it remains essential in today's digital landscape.
