How to Conduct a Vulnerability Assessment on a Network?

Introduction

Every week Indian companies lose crores due to unpatched vulnerabilities in networks (CERT-In 2025). A single open port or outdated software can lead to full compromise. While most organizations remain exposed, students at Ethical Hacking Training Institute & Webasha Technologies learn to perform complete enterprise-grade network vulnerability assessments exactly like pentesters at Deloitte, KPMG, EY, and top Indian banks — making them the most sought-after VAPT professionals in the country.

Real Indian Network Breaches Due to Poor VA

Recent cases we recreate in lab: Air India breach via misconfigured server, BigBasket data leak from exposed Redis, Dominos India via open MongoDB, multiple hospital ransomware attacks due to unpatched RDP (port 3389), and banking networks compromised via outdated Cisco routers — all could have been prevented with proper vulnerability assessment.

See these scenarios live in our enterprise lab — Ethical Hacking Training Institute & Webasha Technologies.

Step-by-Step Professional VA Methodology

Exact 10-step process taught in every batch: scoping & rules of engagement, passive reconnaissance (Shodan, Censys), active discovery with Nmap, vulnerability scanning (Nessus, OpenVAS, Qualys), authenticated scanning, manual verification of findings, CVE mapping & risk rating (CVSS), exploitation attempt (optional), remediation recommendations, and professional report writing with executive summary.

Best Tools for Network Vulnerability Assessment

Licensed tools we provide to every student: Nessus Professional, Tenable.io, Qualys VMDR, OpenVAS, Acunetix, Burp Suite Pro, Nmap with NSE scripts, Nikto, Nuclei, Masscan, ZMAP, and our custom vulnerable network with 100+ real vulnerabilities (Windows, Linux, Cisco, firewalls, IoT devices) for unlimited practice.

Master all these tools hands-on in our CEH + VAPT certification course.

How We Train Better Than Anyone Else

Every student gets personal attacker & victim VMs, enterprise-grade network topology (50+ devices), real vulnerable services (SMB, RDP, SSH, HTTP), weekly new vulnerable machines, monthly 48-hour VAPT challenges, and direct report review by industry pentesters — exactly the same environment used by red teams at top consulting firms.

Career After Network VA Training

Our students are placed as Vulnerability Assessment Analyst, VAPT Engineer, Security Auditor, and Pentester at Deloitte, EY, KPMG, PwC, TCS, Wipro, banks, and government PSUs with fresher packages ₹8–25 LPA and experienced professionals crossing ₹50 LPA — highest in Indian cybersecurity industry.
