We have to admit that web technologies conquered the world. JavaScript development is not about building web applications anymore: you can use JavaScript to build native mobile and desktop applications. However, it brings more significant responsibilities to front-end engineers to make sure that our applications are secure. Do you think that creating a static website will solve all your security problems? We will discuss the modern front-end security landscape, such as tools and techniques used by “bad guys” to compromise your applications in the following session. Next, I discuss why web framework usage is not a “silver bullet” and how you can fight back and mitigate security risks.
