Wireless Security

Introduction

Wireless security refers to the measures taken to protect a wireless network from unauthorized access and misuse. In an increasingly connected world, securing wireless networks is paramount to protect sensitive data and maintain user privacy.

Key Concepts

• **WEP (Wired Equivalent Privacy)**: An outdated security protocol that is easily compromised.
• **WPA (Wi-Fi Protected Access)**: An improved security standard over WEP, providing better data encryption.
• **WPA2/WPA3**: The latest security protocols, utilizing strong encryption methods (AES) and improved authentication processes.
• **SSID (Service Set Identifier)**: The name of the wireless network that identifies it to users.

Security Methods

Securing a wireless network involves various methods, including:

1. **Change Default Settings**: Change the default SSID and password of your router.
2. **Enable WPA3**: If supported, always use WPA3 for better encryption.
3. **Disable WPS**: Wi-Fi Protected Setup can create vulnerabilities; it is advisable to disable it.
4. **Use a VPN**: A Virtual Private Network adds an extra layer of security.

Best Practices

Implementing best practices can greatly enhance wireless security:

• Regularly monitor connected devices.
• Use a strong, unique password for your Wi-Fi network.
• Limit access to the network by MAC address filtering.
• Disable network name broadcasting.
