Task 1 - "Install only applications needed" - this comes down to detailed
understanding of distro install programs (e.g. Anaconda, etc.) which we're
not otherwise testing here. Post installation, it comes down to *not* doing
things; how do we test that a candidate knows how to *not* invoke "rpm
-ivh" ? <g>

Task 2 - "Remove or disable unnecessary services" - I would broaden this to
cover applications and other subsystems. For example, do you really want to
leave gcc installed on that firewall? Development tools such as compilers
should not in fact be installed on any production systems, but one can't
say that in public for fear of offending Gentoo purists. . .

Task 5 - "Understand a Nessus report" - I'd consider moving this to a
"Security Validation" Content Area.

Tasks 7, 8,9,10,11, 12, 14, 15, 17 - I'd make RSBAC a separate Content
Area, if I included it at all (why not SELinux, LIDS, etc?)

Task 13 - Install hardening scripts - *Which* hardening scripts? Bastille?
Others? Got to be specific here.

Task 16 - "Examine hosts.allow", etc. - Perhaps we need more extensive
coverage of tcpwrappers/libwrap; specifically, the extended syntax for
hosts.allow and hosts.deny (see man 5 hosts_options), and how libwrap is
used by sshd and some other things people might not expect.

Task 18 - "store logs on other machines" - perhaps rewrite as "Edit
/etc/syslog.conf to direct selected log messages to a remote host, and
configure syslogd to accept log messages from a remote host".

Task 19 - "Understand User Mode Linux" - Again, I'd categorize this with
RSBAC, SELinux, etc. I don't see employers seeking certified applicants
doing much with UML; in fact, there'd be more mileage in examining on
VMWare.

Task 21 - /etc/issue - has anyone actually seen /etc/issue.net, especially,
or /etc/motd recently? It might be better to look at modifying pre-logon
banners in KDE and GNOME, these days. Or configuring sshd to emit a banner.
. .

Task 23 - "Install and configure a port scan detector" - Which one?
PortSentry seems to be unsupported these days, since Cisco aquired the
developers

Task 24  - "Install and configure log monitoring / alerting software" -
Again, which? Real-time or batch? Swatch?

Best,
