What is the difference between Vulnerability Scanning, Security Auditing, and Penetration Testing?
❓ Interview Prompt: Compare Vulnerability Scanning (automated tool scans), Security Auditing (code & compliance reviews), and Penetration Testing (ethical hacking simulations).
Differentiating offensive and defensive security assessment methodologies:
1
Vulnerability Scanning: Automated SAST/DAST tools (Nessus, Qualys, Snyk) scanning code/networks for known CVE flaws. High false-positive rate.
2
Security Auditing: Systematic review of source code, architecture, and cloud configurations against compliance frameworks (SOC 2, ISO 27001, PCI-DSS).
3
Penetration Testing (Ethical Hacking): Human security experts simulate real-world attack campaigns to exploit unknown flaws, chain vulnerabilities, and compromise target systems.

🎯 Interview Key Takeaway
Vulnerability scanning automates flaw detection; security auditing verifies compliance; penetration testing simulates manual hacking.
