🔍 Vulnerable Programs का Audit करने के लिए Open-Source Tools

🧠 Vulnerable Program Audit क्या है?

जब किसी सॉफ़्टवेयर, एप्लिकेशन या प्रोग्राम की सुरक्षा जांच की जाती है ताकि उसकी कमजोरियों (Vulnerabilities), गलत कॉन्फ़िगरेशन (Misconfigurations), कमजोर Dependencies और सुरक्षा खामियों की पहचान की जा सके, तो उसे Security Audit कहा जाता है।

एक Security Audit निम्नलिखित समस्याओं को पहचानने में मदद करता है:

✅ Known CVEs (Common Vulnerabilities and Exposures)

✅ Hardcoded Passwords

✅ API Keys Exposure

✅ Outdated Libraries

✅ Security Misconfigurations

✅ Insecure Coding Practices

🔍 Open-Source Tools to Audit Vulnerable Programs

🧠 What Is a Software Security Audit?

A software security audit is the process of examining an application, source code, dependencies, configuration, and runtime environment to identify:

• Security vulnerabilities
• Coding flaws
• Misconfigurations
• Outdated dependencies
• Exposed secrets
• Known CVEs (Common Vulnerabilities and Exposures)

Security audits help organizations reduce risk and improve software security before vulnerabilities can be exploited.
