Most people are unaware of how insecure most networks are. For example, wireless networks are subject to "sniffers," which are programs or device that capture all traffic on a wireless local area network (LAN). By using a sniffer, someone can see your e-mail, passwords, URLs visited, and even read the content of your text messages unless you take precautions.

Information (e.g. usernames, passwords and data) travelling on the wireless network is only protected if it is encrypted. Information is encrypted if it is sent using Secure Socket Layer (SSL) protection (i.e. the URL uses https://) or over a Virtual Private Network (VPN).

ICT has taken a big step towards substantially reducing the effect of viruses and worms on the U of S networks by installing the Cisco Clean Access network security system on the wireless network. This system will protect faculty, staff and student laptops, our data and ultimately the wireless network we all share.
