How to Create a Custom Live CD for Secure Remote Incident Handling in the Enterprise
How to Create a Custom Live CD for Secure Remote Incident Handling in the Enterprise Abstract This paper will document a process to create a custom Live CD for secure remote incident handling on Windows and Linux systems. The process will include how to configure SSH for remote access to the Live CD even when running behind a NAT device. The combination of customization and secure remote access will make this process valuable to incident handlers working in enterprise environments with limited remote IT support.

Understand the specifics of the Linux kernel in the management of devices and drivers. Learn to configure the Linux kernel for optimal hotplug management. Understand how hotplug events are generated and how to use them in drivers. Install and use external hotplug daemons: udev, libusb, etc ... Discover Linux kernel changes up to the latest versions (up to 3.6.39 and 3.x). Master the techniques of kernel debugging. We use a recent linux kernel, as provided by the distribution used or available on www.kernel.org. Labs are conducted on target boards, that can be: Atmel ARM9-based boards, with Lauterbach JTAG probes. Labs are conducted using the System Workbench for Linux - Basic Edition IDE, for which all trainees will get a free license, so that they can continue to work, after the training, in a convenient and efficient environment. --> Course environment A PC workstation and a target board per two trainees group. Printed course material.
