Wireless security is a critical aspect of modern networking, protecting data transmitted over airwaves from unauthorized access and cyber threats. Below are key concepts to understand:

🛡️ Core Principles

  • Encryption: Data is scrambled using algorithms like WPA3 or AES to prevent interception.

📡 Key Technologies

  • WPA3: The latest Wi-Fi encryption standard offering stronger security than WPA2.
  • Bluetooth: Secure short-range communication with pairing and encryption features.
  • 5G Networks: Enhanced security protocols for mobile data transmission.

🔑 Best Practices

  1. Enable WPA3 or AES-CCMP encryption on all wireless networks.
  2. Regularly update firmware to patch vulnerabilities.
  3. Use strong, unique passwords for network access.
  4. Disable unnecessary services (e.g., WPS) to reduce attack surfaces.
