The security model of the web

Philippe De Ryck
Monday March 9, 16:00 - 17:30
Short description

The web still depends on the same security model as it did 20 years ago. Even if somewhat flawed, that security model is essential for building secure applications.


The web has undergone a dramatic transformation since the first static HTML documents. However, the underlying security model remains mostly unchanged. Unfortunately, many developers do not have a conscious understanding of the web's security model, its advantages and its limitations.

In this session, we make this underlying security model explicit. We show how to leverage the Same-Origin Policy for security. We illustrate the power of the sandbox, along with other crucial web security concepts, such as cookies. Overall, this session offers the foundation for other web security topics here at SecAppDev.

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.
