Wireless networks are essential for modern connectivity, but they also introduce unique security risks. Understanding how to secure them is critical for both individuals and organizations. Here's a guide to key concepts and practices in wireless security:
🔒 Core Threats to Wireless Networks
- Eavesdropping: Unauthorized interception of data transmitted over Wi-Fi. Use encryption (e.g., WPA3) to mitigate this risk.
- Rogue Devices: Unauthorized access points that mimic legitimate ones. Regularly scan your network for unknown devices.
- Man-in-the-Middle (MitM) Attacks: Attackers position themselves between two parties to intercept communications.
🛡️ Best Practices for Defense
- Enable Strong Encryption: Always use WPA3 or WPA2-AES for secure data transmission.
- Update Firmware: Keep your router and access points updated to patch vulnerabilities.
- Implement Network Segregation: Separate guest networks from internal systems to limit exposure.
- Use Captive Portals: Control access to your network with authentication mechanisms.
- Monitor Traffic: Deploy tools like Wireshark to detect suspicious activity.
