Gone are the days when developers had to craft their own session management systems and rely on CGI calling Perl scripts (hopefully!). Today, programming languages and frameworks offer a wealth of built-in security features—often for free. But what exactly do these features provide, and how can we leverage them to elevate our security code reviews, penetration testing practices, and even compliance efforts? In this talk, we'll explore the security mechanisms that modern frameworks and languages offer out of the box. We'll dive into how understanding these built-in tools can transform your approach to code review and penetration testing, allowing you to focus on the nuances and deeper issues that could compromise your application’s security. Whether you're a security professional, developer, or compliance officer, this session will equip you with the knowledge to make the most of the features at your disposal and ensure your applications are as secure as possible.
