So if you’ve read previous posts you should be caught up on the basics of wi-fi security: encrypt your network, use WPA or WPA2, change the default settings, etc. In this two part series, we’re going to cover some advanced security measures for your wireless network.
1. Enterprise Encryption
Most likely you are only using the Personal or Pre-shared Key mode of your Wi-fi Protected Access (WPA). This only requires an encryption key that must be given when connecting to the wireless network. You can achieve better central management and overall wi-fi security by setting your WPA to “Enterprise” mode, which requires 802.1X/EAP authentication to connect wirelessly. This means each user needs a unique username and password to login. The encryption key will be derived securely from these fields so that your encryption key remains completely confidential.
Additionally, this allows you to change or revoke access to certain users. Should an employee ever leave the company or steal a laptop, you can simply change their user settings from the central control. If you were only using personal or pre-shared key mode, you would have to change the encryption key and alert the remaining users of the change.
2. Physical Security
While most of your wireless security will rely on technical equipment and know-how, a great deal of security efforts will remain in the physical realm. If you leave an Ethernet port or router in plain sight, someone can easily link up at that port to access your network. Additionally they could press the reset button on the router to restore it to default settings leaving your network wide open. Network components should be secured and out of sight.
3. Intrusion Detection/Prevention System (IDS/IPS)
An intrusion detection or prevention system is a piece of software that uses your wireless adapter to monitor Wi-fi signals for problems. They help detect unknown or rogue APs or alert you when an AP settings don’t match the standards you’ve defined. They also analyze network packets to monitor and prevent hacking or jamming.
