5-2-1 Recommendations to maximize RGS security HP recommends the following practices to maximize RGS security: • Use fiber networking because it is more secure. • The "last meter" can be copper to the client computers • Use an optical LAN card for a single display Thin Client (the LAN card occupies an expansion module, so the computer is limited to a single display) • Fully separate networks for different security regions • System isolation • Separate enclosures and subnets for each security region • Physical separation of all links • Multiple client systems at desk for multiple blades with keyboard/mouse switching. Figure 5-4 shows a system designed to maximize security.
