वल्नरेबिलिटी स्कैनिंग क्या है?
वल्नरेबिलिटी स्कैनर स्वचालित रूप से सिस्टम, नेटवर्क और एप्लिकेशन की जाँच करता है। यह निम्न काम करता है:
होस्ट/सेवाओं की खोज
संस्करण एवं कॉन्फ़िग जांच
ज्ञात सुरक्षा त्रुटियों से मिलान
रिपोर्ट और संवेदनशीलता श्रेणी देना
स्कैनर प्रकार:
नेटवर्क स्कैनर
वेब एप्लिकेशन स्कैनर
होस्ट / एजेंट-आधारित स्कैनर
क्लाउड / कंटेनर स्कैनर

Introduction
In cybersecurity, vulnerability scanning is indispensable: before any attacker exploits weaknesses, defenders must find them first. A vulnerability scanner systematically inspects networks, systems, and applications to detect known vulnerabilities, misconfigurations, missing patches, weak credentials, and more. (Red Canary)

Let’s get started.
What Is Vulnerability Scanning?
A vulnerability scanner is a software that automates the detection of security flaws in systems, networks, and applications. It often works by:
Discovering hosts and services
Matching services, versions, and configurations against known vulnerability databases (CVEs, NVD)
Generating reports with severity, evidence, and remediation suggestions
There are different scopes:
Network Vulnerability Scanners — scan servers, routers, open ports
Web Application Scanners — scan web apps for SQLi, XSS, CSRF, etc.
Cloud / Container Scanners — detect insecure misconfigurations in cloud environments and container images
Host / Agent-Based Scanners — installed on endpoints to detect local issues
Each type plays a role in a layered vulnerability management strategy. (Ionix)
Key Features to Look For
Before choosing a tool, evaluate:
Coverage: network + web + cloud + containers
Credentialed Scans: deeper insight with authorized access
Scalability & Performance
Regular Plugin / Database Updates
Reporting & Export Formats
Integration with ticketing, patch management, SIEM
Low False Positives / Tuning Capability
Automation & Scheduling
