Security | 7.2.8 Lab: Scan for Web Services with Nmap Walkthrough | TestOut | CompTIA Network+

This walkthrough documents my ongoing hands-on journey through networking, troubleshooting, and Information Technology learning as I work toward CompTIA Network+ certification and deeper practical networking knowledge. In this lab, I use Nmap to perform a port scan against a database server to identify open ports and discover available network services.

This walkthrough focuses on network reconnaissance, port scanning, service discovery, and security analysis techniques commonly used by network administrators, security analysts, and cybersecurity professionals.

In This Lab:

• Use Nmap to perform a port scan
• Identify open ports on a server
• Discover active network services
• Analyze service availability
• Explore network reconnaissance techniques
• Strengthen security and troubleshooting skills

Lab Scenario

As a security analyst, I have been tasked with evaluating a database server used by the finance and accounting departments. The goal is to determine which ports and services are exposed and assess the server's attack surface.

Target Server:
• Database Server — 192.168.0.22

Topics Covered

• Nmap Port Scanning
• Open Port Identification
• Service Discovery
• Network Reconnaissance
• TCP/IP Networking
• Network Security Fundamentals
• Vulnerability Assessment Concepts
• CompTIA Network+ Concepts

Why This Lab Matters

Before securing a system, administrators must understand which services are exposed to the network. Nmap allows technicians and security professionals to identify active services, detect unnecessary open ports, and reduce security risks by minimizing the attack surface.

Understanding port scanning is valuable for:

• IT Support
• Network Administration
• Security Operations
• Cybersecurity Analysis
• Vulnerability Management
• Infrastructure Security

Skills Demonstrated

• Port Scanning
• Service Enumeration
• Network Diagnostics
• Security Assessment
• TCP/IP Analysis
