Make Your Home Wireless Network Secure
The affordability and ease of use of basic wireless access points (WAPs) has prompted many Penn users to set up "hot spots" at home.
- On each WAP you use, change the default administrator password to a strong password.
- Change the default SSID, or "name" of each WAP to a unique name of your own choosing.
- Disable broadcasting of your network name (SSID) to make your network less visible to unauthorized users.
- Enable and require the strongest encryption that your WAPs offer - usually 128-bit Wireless Encryption Protocol (WEP). This will encrypt all traffic traveling across your wireless network.
- Regularly check for, and install, updated versions of the firmware for your WAPs and software drivers for your wireless Ethernet adapters.
- Enable and require MAC (Media Access Control) address filtering on each WAP. This will let you specify which individual computers may access the WAP, identified by the unique MAC addresses associated with their Ethernet adapters.
Follow these instructions for locating MAC addresses:
1. From the Apple menu, choose System Preferences.
2. From the Show menu, select AirPort.
3. Click the AirPort tab. The AirPort’s MAC address is displayed at bottom.
