How to Test Security of 3rd-Party Libraries and Dependencies

Third-party libraries and dependencies power modern applications but can expose your system to security risks. Cybercriminals often target outdated or poorly maintained libraries, leading to data breaches, ransomware attacks, and service disruptions.

However, you can secure third-party libraries and dependencies by leveraging SAST (Static Application Security Testing) and DAST (Dynamic Application Security Testing). Here’s a guide from TRIOTECH SYSTEMS, experts in application security services, on how to effectively test them and keep your applications secure.

What Are Third-Party Libraries and Dependencies?

Third-party libraries are pre-built code packages developers use to add features without creating everything from scratch. Dependencies refer to external modules your project needs to function.

Examples of Third-Party Libraries and Dependencies:

• Libraries: React.js, Lodash, jQuery
• Dependencies: Database connectors, payment gateways, API clients

Why You Must Secure Third-Party Libraries and Dependencies

Unsecured libraries are common entry points for hackers. Vulnerabilities like outdated libraries, weak authentication, and unchecked updates can cause severe damage, including system breaches, data loss, and reputational harm.

How to Secure Them Using SAST and DAST

1. Test with SAST (Static Application Security Testing)

SAST identifies security issues in the code before deployment. Here’s how it helps:

1. Integrate SAST into Development: Set up automated SAST tools in your CI/CD pipeline.
2. Scan Source Code Regularly: Ensure all libraries are scanned for known vulnerabilities.
3. Check Dependency Trees: Detect indirect dependencies prone to security issues.
4. Fix Issues Promptly: Address flagged vulnerabilities using secure patches.

Example: Suppose your project uses a payment processing library. SAST scans can reveal outdated cryptographic modules, prompting immediate updates.

2. Test with DAST (Dynamic Application Security Testing)

DAST scans applications in real time to uncover vulnerabilities while running. Follow these steps:

1. Deploy DAST in Staging: Use a staging environment for tests to avoid production risks.
2. Simulate Attacks: Perform simulated attacks to identify weak entry points.
3. Analyze Responses: Examine how the application reacts to unexpected inputs.
4. Prioritize Critical Fixes: Address critical flaws like SQL injection or XSS attacks quickly.

Example: Testing a customer login module using DAST could reveal unprotected session tokens, enabling secure session management.
