NPM security is a crucial topic in software development, as it can impact the stability and integrity of applications built using the npm ecosystem. Supply chain attacks, such as dependency confusion attacks, spearheading malicious code backdoors in open source packages, and compromising build pipeline infrastructure, pose an imminent threat to developers. To prevent supply chain attacks, developers can apply software security controls, including preventing NPM lockfile injection, arbitrary command execution, blind NPM package upgrades, dependency confusion, and Trojan source attacks. Proactive measures such as using tools like npq and Snyk Advisor can help detect and prevent security vulnerabilities in npm packages. Additionally, developers can use Snyk's free tooling to scan and monitor for malicious packages and assess open source package health. By understanding NPM security best practices and taking proactive steps, developers can protect themselves against supply chain attacks and ensure the integrity of their applications.
