The ultimate guide to Content Security Policy

Lukas Weichselbaum
Wednesday March 11, 14:00 - 15:30
Short description

Even with hardened frameworks and thorough security reviews, there's no guarantee that an application is free of XSS. In this session, I'll present different flavors of CSP, which can serve as a robust defense-in-depth mechanism against XSS.

Abstract

Google is a prime target for attackers. As a result, Google has plenty of experience battling all kinds of XSS attacks. In recent years, they have successfully deployed a nonce-based CSP, one of the most misunderstood and arguably, most powerful web mitigation techniques.

This session provides an in-depth technical analysis of the effectiveness of different flavors of CSP for the many classes of XSS vulnerabilities, busting myths, and common misunderstandings, and explore the often fuzzy boundaries between hardening and mitigation techniques.

Key takeaway

Understand how to use CSP as a robust defense-in-depth mechanism against XSS.

Building secure frontend web applications

One-day workshop by Jim Manico

Cross-Site Scripting (XSS) is the achilles heel of almost every web application. Even in the modern world, where applications are built with JavaScript frameworks, XSS requires attention to details. To build secure applications, developers need to be aware of current best practices for their particular framework. This one-day workshop offers an in-depth perspective on XSS in the modern web. We look at XSS defenses from various angles, including the elaborate Content Security Policy.
