Chapter 4. Secure Remote Administration

Your server is bastionized, it resides in a firewall-protected DMZ network, and its services are fully patched and configured for optimal security. You've just installed it in a server room, which is monitored by surly armed guards and accessible only after peering into a retinal scanner and submitting to a body cavity search. Not that you plan to visit the system in person, though; it'll be no problem to perform your administrative duties from the comfort of your office, thanks to good old Telnet.
