Description
This video was recorded on http://wrocloverb.com. You should follow us at https://twitter.com/wrocloverb. See you next year! zOMG Rails is insecure, PHP is insecure, Java is insecure - Everyone re-write everything in Haskell now! As much as coders love hating on languages and frameworks, the biggest security risk to you code is you. Come get a history of web security, and a live demo of security exploits. Then learn how to avoid them in your own code. You'll walk away with actionable steps to make your apps more safer, and a better understanding and appreciation of what being secure really means.

In the video titled "Security, Secrets and Shenanigans," Richard Schneeman discusses the importance of web application security, focusing on common exploits and how developers can protect their code. The session aims to demystify security concepts and encourages developers to take responsibility for their code's security instead of relying solely on security researchers. Here's a breakdown of the key points discussed: - **Introduction to Web Security**: Richard opens by emphasizing that security risks often stem from developers' actions rather than the inherent flaws of the programming languages themselves. - **Common Vulnerabilities**: He explores a myriad of common security vulnerabilities, including: - **DDoS Attacks**: Highlighting the challenges of keeping systems available amidst overwhelming traffic, Richard explains how malicious actors can exploit server vulnerabilities, particularly as user bases grow. - **Memory Exploits in Ruby**: Discussion is made on symbols in Ruby and how improperly handled user input can deplete server memory, leading to outages. - **Parser Exploits**: Richard illustrates XML parsing vulnerabilities with the "Billion Laughs" attack, stressing the importance of using robust parsers. - **Authentication Security**: Although briefly touched upon, authentication forms a core component of securing applications. Richard highlights the risks associated with YAML parsing and the need to avoid executing code during deserialization. - **CSRF Risks**: Addressing Cross-Site Request Forgery, Richard stresses the need for proper token configuration to prevent unauthorized access to forms. - **Best Practices for Secret Management**: He recommends that developers avoid hardcoding sensitive information in source control, employing environment variables instead to keep secrets safe. This also allows for dynamic configuration management without frequent redeployments. - **Proactive Security Measures**: Emphasizing proactive education, Richard encourages developers to stay informed about security vulnerabilities and participate in projects like Code Triage to help raise awareness and improve code security practices. **Conclusion**: Richard urges developers to recognize that security is an ongoing process, highlighting that nothing is ever 100% secure. The key takeaways include using environment variables for secrets, adopting best practices to sanitize inputs, and continually educating oneself about security vulnerabilities to maintain robust applications. He closes his talk with an invitation for questions, fostering a collaborative approach to discussing security challenges in the developer community.
