Notes I presented this paper at Linux Kongress 2002. Since that time virtualisation systems based around VMWare, Xen, and the hardware virtualisation in recent AMD and Intel CPUs has really taken off. The wide range of virtualisation options makes this paper mostly obsolete, and what isn’t obsoleted by that is obsoleted by new developments in […] Here are links to some instances when SE Linux prevented exploits from working or mitigated their damage: […] Based on past mistakes by myself and others, here is a check-list before putting a Linux (or other Unix) server online: Run memtest86+ (or an equivalent program for other architectures) before going live, ideally run it before installing the OS.
