The State of JavaScript Security in 2024

AI is used to analyze code for vulnerabilities, acting as a workforce to inspect dependencies. However, there are risks due to AI being trained on vulnerable code, necessitating additional checks.

Firas is an open source contributor with around 10 years of experience, having written about a hundred npm packages such as Web torrent and standard JS. He has also worked on polyfills used in Browserify and Webpack, and has taught a course on web security at Stanford.

Socket is a tool designed to protect code by checking for vulnerabilities and malicious dependencies. It is used by various organizations to secure their repositories and prevent attacks.

Dependency hell occurs when an application cannot install dependencies due to version conflicts. NPM solves this by allowing multiple versions of a package to be installed simultaneously, avoiding such conflicts.

Transitive dependencies occur when a package you install directly depends on another package, creating a chain of dependencies throughout the dependency tree.

JavaScript security is challenging due to the complex, intertwined technologies of modern web applications, which come with subtle security consequences. Additionally, the ecosystem is vast with many dependencies, making it susceptible to attacks.

Socket offers advanced detection of supply chain attacks and malicious code, which Dependabot does not cover. Socket analyzes every line of code in dependencies to identify potential threats.

Developers should understand their dependencies, use modern security tools, prioritize secure design, and stay informed about the OWASP top ten vulnerabilities. Hiring a pen tester is also recommended.

Common vulnerabilities include broken access control, cryptographic failures, injection, insecure design, and vulnerable or outdated components, according to the OWASP top ten.

The noise problem involves receiving too many alerts, many of which are false positives. Socket addresses this by prioritizing severe threats like supply chain attacks over less critical vulnerabilities.
