No one get's an internet connection, all USB ports are phyiscally removed as are all other ports that could be used for memory such as flash cards, all media drives such as CDs and DVDs are physically remove, drives are fully encrypted such as Elliot suggests, keyboards, mice, and monitors are all soldered in place instead of simply being plugged in, all rooms are radio shrouded using fine mesh grounded copper screening, no electronic devices are allowed such as calculators, cell phones, no one can bring in or out a pencil, etc, no one is allowed to talk, and cavity searchs for everyone! 😀
