Operator is a complete Linux (Debian) distribution that runs from a single bootable CD and runs entirely in RAM. The Operator contains an extensive set of Open Source network security tools that can be used for monitoring and discovering? networks. This virtually can turn any PC into a network security pen-testing device without having to install any software. Operator also contains a set of computer forensic and data recovery tools that can be used to assist you in data retrieval on the local system.
"The technique to allow Operator to boot and run from RAM is based on a project called KNOPPIX. KNOPPIX is a bootable CD with a collection of GNU/Linux software, automatic hardware detection, and support for many graphics cards, sound cards, SCSI and USB devices and other peripherals. KNOPPIX can be used as a Linux demo, educational CD, rescue system, or adapted and used as a platform for commercial software product demos. It is not necessary to install anything on a hard disk. Mastering of this CD uses on-the-fly decompression which allows for up to 2 GB of stored data.
Starting with the 3.3 version of Operator, we have started completely from scratch by installing a basic Debian installation then adding the KNOPPIX functionality afterwards. This allowed us to have more control and understanding of what is on the CD."?www.ussysadmin.com/operator/
