Most people don't realize how insecure most networks are. For example, many old networks are subject to "sniffers," which are programs or devices that capture all traffic on a local area network (LAN). By using a sniffer, someone can see your email; passwords, URLs visited, and even read the content of your text messages unless you take precautions.
The best way to protect yourself from someone seeing your private information is by using a form of encryption, which encodes your data. Encryption is available for individual applications.
For example, most Web sites doing sensitive transactions will use SSL (Secure Socket Layer). You can see which Web sites use SSL by looking at the URL. If SSL is in use, the URL will start with HTTPS:// (instead of HTTP://) and any text (except the actual URL) will be encrypted between you and the Web server, thus making sniffing useless.
Several other systems use encryption:
- SSH (Secure Shell) is used instead of Telnet and to tunnel some protocols
- SSL/TLS is used to tunnel other non secure protocols
- SFTP (usually part of an SSH client) is used instead of FTP
Some other applications are harder to secure at the application (email being the most widely used).
TRU's Guest Wireless Network does NOT have any built-in security. Do NOT transmit any sensitive or personal information that you do not want others to know over this network unless you are connected to a VPN (Virtual Private Network) or a Website using SSL or some other encrypted protocol.
For maximum security please ensure:
- You use an encrypted path to transmit any sensitive or personal data
- Your virus software is up to date with the latest virus signatures
- Your Computer has been fully updated
- You are using a personal firewall
