Task 1: Network Scan using Nmap

This repository contains the output for Task 1 of the Cybersecurity Internship at Elevate Labs.

🔍 Objective

Scan the local network to discover open ports and understand network exposure.

🛠 Tools Used

• Nmap – for port scanning
• Windows Command Prompt
• (Optional) Wireshark – for packet analysis

🧠 Steps Performed

1. Installed Nmap on Windows.
2. Found my local IP range using ipconfig – identified range as 192.168.0.0/24.
3. Ran a TCP SYN scan:

   nmap -sS 192.168.0.0/24
   

Saved results to scan_results.txt using: bash Copy code nmap -sS 192.168.0.0/24 -oN scan_results.txt

Output See the scan_results.txt file in this repository.

🔐 Observations Identified active devices on the network.

Noted the open ports and services on each.

Open ports such as 22 (SSH), 80 (HTTP), and 443 (HTTPS) can be entry points if not secured.

📚 Key Concepts Learned What open ports are and how they can expose a network
