The top three wireless network attacks are Man-in-the-Middle (MitM) attack, Denial-of-Service (DoS) attack, and Wireless Jamming attack. Out of these attacks, the Man-in-the-Middle attack has the capability of causing the most damage. This is because a MitM attack enables an attacker to intercept data transferred between two parties, potentially allowing them to access sensitive information, tamper with the data, or even modify their identity.
To protect your wireless network, the following steps should be taken:
1. Use strong encryption for your wireless network.
2. Use a virtual private network (VPN) when accessing public networks.
3. Enable two-factor authentication on all devices connected to the network.
4. Install a firewall and regularly update your router's firmware.
5. Use an intrusion detection system to monitor and detect potential attacks.
6. Disable any services not in use.
7. Change your network's SSID and password regularly.
