Wi-Fi Network Analysis and Security
This guide covers the basics of analyzing Wi-Fi networks and assessing their security.
What Is Wi-Fi Network Analysis?
• Discover nearby Wi-Fi networks (SSID, signal strength)
• Identify encryption types (WEP, WPA, WPA2, WPA3)
• Assess vulnerabilities (weak passwords, outdated protocols)
• Analyze authentication and data transmission
Tools Needed
• Wi-Fi adapter with monitor mode support (e.g., Alfa AWUS036NHA)
• Software tools:
• Aircrack-ng — for capturing handshakes and cracking WPA/WPA2 keys
• Kismet — passive Wi-Fi traffic analyzer
• Wireshark — packet analysis tool
• Reaver — WPS attack tool
• Kali Linux (or another pentesting OS with pre-installed tools)
Steps for Wi-Fi Analysis and Security Testing
1. Scan and Discover Networks
Use airodump-ng or kismet to list available networks, their BSSID, channels, encryption type, and signal strength.
2. Identify Encryption Type
Check if the network uses WEP (weak), WPA/WPA2 (stronger), or WPA3 (most secure).
3. Check for Vulnerabilities
• WEP networks can be cracked by capturing enough packets.
• Networks with WPS enabled can be targeted using Reaver.
• For WPA/WPA2, capture the handshake and attempt password cracking with dictionaries or brute force.
4. Analyze Traffic
Use Wireshark in monitor mode to inspect packets, detect unencrypted traffic, or potential data leaks.
How to Secure Your Wi-Fi Network
• Use WPA3 or at least WPA2 with a strong, complex password.
• Disable WPS or use it carefully.
• Optionally hide your SSID.
• Enable MAC address filtering as an additional layer.
• Keep router firmware up to date.
