Hi there. I am wondering what security issues arise when using a LiveCD on a machine with an existing OS, in particular Windows. I understand that Knoppix can mount partitions in read-only mode. In such case, one may still save work to a Zip-disk, USB-key, etc. However, as regards access to authentication servers, (we're in a large campus which is predominately Windows (clients and servers)), network access, etc., does the use of a LiveCD (be it Linux, BSD, etc) impose any significant security threats to the existing infrastructure? Thanks in advance.
