1
Welcome to Wireless Standards & Encryption
Understanding wireless standards and encryption methods is essential for securing wireless networks.
2
Wireless Networking Standards
Wireless communication follows specific standards defined by IEEE 802.11.
3
Common IEEE 802.11 Standards
- 802.11a - Operates at 5 GHz with speeds up to 54 Mbps.
- 802.11b - Operates at 2.4 GHz with speeds up to 11 Mbps.
- 802.11g - Backward-compatible with 802.11b, up to 54 Mbps.
- 802.11n - Uses MIMO for speeds up to 600 Mbps.
- 802.11ac - Supports gigabit speeds and multiple users.
4
Why Wireless Encryption is Important
Encryption protects wireless communication from unauthorized access and eavesdropping.
5
Common Wireless Encryption Methods
- WEP (Wired Equivalent Privacy) - Weak security, easily cracked.
- WPA (Wi-Fi Protected Access) - Stronger encryption than WEP.
- WPA2 - Uses AES encryption for strong security.
- WPA3 - Latest encryption standard with enhanced security.
6
Cracking WEP Encryption
WEP encryption is vulnerable to cracking using tools like Aircrack-ng.

Best Practices for Wireless Security
- Use WPA2 or WPA3 encryption.
- Disable WPS to prevent brute-force attacks.
- Change default SSID and passwords.
- Enable MAC address filtering.

9
How to Secure a Wireless Network
- Use strong encryption and passwords.
- Limit network access to authorized devices.
- Regularly update firmware and security settings.
