"Secure Server" package
A package that depends on a suite of security and server management software that has been well integrated and tailored to Ubuntu Server (e.g. snort, prelude, aide, samhain, ossec, bastille, tiger, nessus, nagios...). Currently such packages exist but they are not integrated and there is no single GUI to access them. Providing such a security package could boost linux server usability as ubuntu did for desktop. And it could improve ubuntu server's image as a rather "insecure" server option.
