Network Security Recommendations
To help deter unauthorized access to your product over a network, you should protect your network
environment using appropriate security measures.
Security measures such as these can help deter threats such as loss of user data, use of telephone and
fax lines, and other intrusions:
• Enable security on your wireless LAN
Enable the appropriate security on the wireless LAN you plan to use with your product. Network
security such as a network password can deter interception of traffic over the wireless LAN. Your
router may already have a default password enabled by your Internet service provider (ISP). See your
ISP and router documentation for instructions on how to change the default password and better
secure your network.
• Connect your product only to a network protected by a firewall
Connecting your product directly to the Internet may leave it vulnerable to security threats. Instead,
connect it to a router or other network connection protected by a firewall. Your router may already
have a firewall set up by your Internet service provider; check with your ISP for confirmation. For best
results, set up and use a private IP address for your network connection.
• Change the default administrator password on your product
If your product has an option to set an administrator password, change the default administrator
password to deter access by unauthorized users to personal data stored on your product, such as IDs,
passwords, and contact lists.
