What Are the Differences Between CEH2 Between CEH and OSCP Labs?

Introduction

Vulnerability Scanning & Analysis is one of the highest-weightage modules in both CEH theory (12–15%) and practical exams (4–6 flags). It is the bridge between scanning and actual exploitation — without accurate vuln scanning, you waste hours on dead ends. Toppers score full marks here because they know how to run authenticated scans, interpret results, eliminate false positives, and map findings to real exploits. At Ethical Hacking Training Institute we provide 500+ real vulnerable servers, routers, web apps, and workstations so every student performs 50+ full enterprise scans before the exam.

Top 6 Vulnerability Scanners You Must Master for CEH

• Nessus Professional – most accurate commercial scanner
• OpenVAS / Greenbone – best free alternative
• Nmap + NSE vuln scripts – lightweight & fast
• Nikto – dedicated web server scanner
• Qualys Community Edition – cloud-based scanning
• Our institute cloud lab – all tools pre-installed

Authenticated vs Unauthenticated Scans – The Critical Difference

Master authenticated scans for better results.

Step-by-Step Vulnerability Scanning Workflow 

First define scope and get authorization. Run discovery scan with Nmap -sn. Perform full port scan with Nmap -p- -sV. Launch Nessus/OpenVAS authenticated scan with provided credentials. Export detailed report. Manually verify every critical/high finding. Map CVEs to Exploit-DB or Metasploit modules. Write professional report with CVSS scores and remediation steps. Our daily scanning challenges make this workflow second nature.

How to Eliminate False Positives Like a Pro

• Verify with manual exploit attempt
• Check actual patch level via commands
• Use multiple scanners for confirmation
• Run authenticated scan if possible
• Document verification steps in report
• Our lab gives 100+ false-positive challenges

Avoid common mistakes in verification.

CVSS Scoring & Risk Prioritization Explained

CVSS v3.1 Base Score ranges from 0.0–10.0. 0.1–3.9 = Low, 4.0–6.9 = Medium, 7.0–8.9 = High, 9.0–10.0 = Critical. Always consider Temporal (exploit code maturity) and Environmental (business impact) scores for real-world reports. In CEH practical, correctly identifying 2–3 critical vulnerabilities is enough for full marks in this section.

Reporting & Documentation Standards for CEH

• Executive summary + technical details
• Risk rating with CVSS score
• Proof of concept screenshots
• Remediation steps for each finding
• Professional Word/PDF template
• We provide ready templates used by MNCs

Learn proper reporting for professional success.
