Sendmail daemon secured

NOTE: All of these services are prohibited with a 'high' security

setting, but if they are re-enabled manually the hostname

information will remain hidden.

Sendmail is forced to perform only outgoing mail. No incoming

mail will be accepted.

Sun's nddconfig security tool is run. For additional information,

view Sun's document, Solaris Operating Environment Network

Settings for Security, at

http://www.sun.com/solutions/ blueprints/1200/network-updt1.pdf.

The system stack is made non-executable. This is done so

security exploitation programs cannot take advantage of the

Solaris OE kernel executable system stack and thereby attack the

system.

The NFS server normally accepts requests from any port number.

The NFS Server is altered to process only those requests from

privileged ports. Note that with the high security setting, NFS is

disabled; however if the service is re-enabled manually, the port

restriction will still apply.

The Remote CDE login is disabled.

The Xerox FreeFlow Print Server router capabilities is disabled

(empty/etc/notrouter file created).
