Modern development often relies on third-party libraries and packages. While convenient, these dependencies may contain vulnerabilities or even malicious code. Package monitoring is the practice of tracking and auditing software dependencies to ensure they remain secure. Developers can automate monitoring using tools like OWASP Dependency-Check, Snyk, or built-in repository scanners that check against vulnerability databases. Continuous monitoring ensures that outdated or vulnerable packages are flagged for updates, preventing attackers from exploiting weaknesses in external code.
