As high-speed Internet technologies grow more popular, so does the frequency of hacking attacks. Such attacks have traditionally been directed primarily at corporate and university networks. Sniffing programs are designed to seek out vulnerable computers, and to make easy the access to data and programs, sniffing programs are widely available for free download from the Internet.

There has recently been a fourfold increase in the risk of always-on machines getting hacked. The most popular targets are sites like ICSA's, which present a special challenge to committed trespassers. ICSA reports receiving at least 20 full-blown attacks a day, and is tested every 5 minutes for vulnerability. Security Awareness File sharing is an operating-system networking feature that allows users to read, change or delete files on all machines attached to the network. This is a useful tool for connecting two or more computers for sharing access to all files from any one machine.
