permitting the administrator to select a securelevel top operate
at. Include a helpfile summarizing some of the information from
init(8). This allows for explicit configuration of securelevels,
which was previously implicit in Security Profile selection.
Currently, there are no checkboxes for the active securelevel,
because sysinstall's facilities for deriving "current settings"
from rc.conf may use only one variable, not two, and I opted for
the simplest approach at this point.

selection is used to drive two configuration parameters:
(1) Default enable/disable for sshd
(2) Default enable/disable for securelevels
Replace this with an explicit choice to enable/disable sshd. A
follow-up commit will add a configuration option to the Security
post-install configuration menu to set the securelevel in rc.conf
explicitly. This should reduce the level of foot-shooting associated
with accidental enabling of securelevels, make the nature and
implications of the securelevel configuration options more explicit,
as well as make the choice to enable/disable sshd more explicit.

(1) Don't modify the configuration of the NFS server as a result of
selecting a profile. We already explicitly prompt for the NFS
server configuration during install, and the user may not get
much advance notice that we're turning it off again. Instead,
use profiles (for better or for worse) only for security tuning.
(2) Don't modify the sendmail setting as part of the security profile:
use the default from /etc/defaults/rc.conf rather than explicitly
specifying. Note that the default in /etc/defaults/rc.conf is
more conservative than the explicit rc.conf entry added by
sysinstall during install, as it does not permit SMTP delivery.
(3) Update "congratulations on your profile" text to reflect these
changes.
Note that security profiles now affect only the securelevel and sshd
settings. My leaning would be to make sshd an explicit configuration
option, move securelevels to the security menu, and drop security
profiles entirely. However, that requires more plumbing of sendmail
than I'm currently willing to invest.
We may want to add a "permit SMTP delivery" question to the install
process.
- Add 'enable_exim="YES"' to rc.conf(5)
- Use the default exim configuration file from the port
- When using sendmail, disable some more scripts that use sendmail specific
parameters
- Have sysinstall tweak mailer.conf(5) substitution
- Use 'N' flag for newsyslog(8)

o Move nfs_reserved_port_only out of security profiles (where it was
set somewhat improperly) to the Security options menu directly.
Previously, the variable was set to true for Moderate, but not for
Extreme, which is at best inconsistent.
o Update the Security Profiles help file to remove reference to the
NFS reserved port.
o Note that the kernel currently defaults the sysctl to '0', but
sysinstall has changed it to '1' as a default as of late; however,
rc.conf sets the value to NO as the default. This change brings

by providing the opportunity to edit inetd.conf during the system
installation process. The following modifications were made:
(1) Expand the Anonymous FTP description dialog to indicate that inetd
and ftpd must be enabled before it can be used.
(2) Introduce a new configInetd() pair of dialogs, the first describing
inetd, giving a couple of examples of services that require it, and
hinting at potential risk, then asking the user if they wish to
enable it. The second indicates that inetd.conf must be configured
to enabled specific services, and asks if the user would like to
load inetd.conf into the editor to modify it. Add this
configuration action to the index.
There are some further improvements that might be considered:
(1) Provide a more inetd.conf-specific configuration tool that speaks
inetd.conf(5). However, this is made difficult by the "yet another
configuration format" nature of inetd.conf, as well as its use of
commenting to disable services, rather than an in-syntax way to
disable a service without commenting it out. Submissions here
would probably be welcome.
(2) There's some overlap between settings in the somewhat obtuse
Security Profile mechanism and other settings, including the inetd
setting, and NFS server configuration. As features become
individually tunable, they should probably be removed from the
security profile mechanism. Otherwise, somewhat counter-intuitively,
sysinstall (in practice) queries multiple times whether inetd, nfsd,
etc, should be enabled/disabled. A possible future direction might
be to drive profiles not by degree of paranoia, rather, the set
of services desired. Or simply to remove the Security Profile
mechanism and resort to feature-driven configuration.
