Looking at systems
Another perspective to consider is "how many people understand the commands to operate?"
Novice users will only execute commands and menus that they are familiar with. Thus, a computer system that utilizes commands with different format (think a foreign language) could be considered safer.
Much like if you and a friend were in a restaurant and spoke in French. Some may be able to hear what you say, and a smaller set of people sitting nearby might (or might not) be able to speak French. Therefore, your conversation would be statistically more secure.
There are of course caveats. Just as some people are fluent in many languages, you may not be as safe as you thought. Also, this theory would not apply if you were at a company where there was an expectation of advanced computer skills. To my spoken language analogy, people should not expect to speak in confidence in any language at the cafeteria at the United Nations Building.

NAME
XPAMethod - XPA Communication Methods
SYNOPSIS
XPA supports both inet and unix (local) socket communication.
DESCRIPTION
XPA uses sockets for communication between processes. It supports three methods of socket communication: inet, localhost, and unix. In gen-
eral, the same method should be employed for all XPA processes in a session and the global environment variable XPA_METHOD should be used
to set up the desired method. By default, the preferred method is "inet", which is appropriate for most users. You can set up a different
method by typing something like:
setenv XPA_METHOD local # unix csh
XPA_METHOD=local; export XPA_METHOD # unix sh, bash, windows/cygwin
set XPA_METHOD=localhost # dos/windows
The options for XPA_METHOD are: inet, unix (or local), and localhost. On Unix machines, this environment setup command can be placed in
your shell init file (.cshrc, .profile, .bashrc, etc.) On Windows platforms, it can be placed in your AUTOEXEC.BAT file (I think!).
By default, inet sockets are used by XPA. These are the standard Internet sockets that are used by programs such as Netscape, ftp. etc.
Inet sockets utilize the IP address of the given machine and a (usually random) port number to communicate between processes on the same
machine or between different machines on the Internet. (Note that XPA has an Access Control mechanism to prevent unauthorized access of XPA
access points by other computers on the Net). For users connected to the Internet, this usually is the appropriate communication method.
For more information about setting up XPA communication between machines, see Communication Between Machines.
In you are using XPA on a machine without an Internet connection, then inet sockets are not appropriate. In fact, an XPA process often will
hang for many seconds while waiting for a response from the Domain Name Service (DNS) when using inet sockets. Instead of inet sockets,
users on Unix platforms can also use unix sockets (also known as local sockets). These sockets are based on the local file system and do
not make use of the DNS. They generally are considered to be faster than inet sockets, but they are not implemented under Windows. Use
local sockets as a first resort if you are on a Unix machine that is not connected to the Internet.
Users not connected to the Internet also can use localhost sockets. These are also inet-type sockets but the IP address used for the local
machine is the localhost address, 0x7F000001, instead of the real IP of the machine. Depending on how sockets are set up for a given plat-
form, communication with the DNS usually is not required in this case (though of course, XPA cannot interact with other machines). The
localhost method will generally work on both Unix and Windows platforms, but whether the DNS is required or not is subject to individual
configurations.
A final warning/reminder: if your XPA-enabled server hangs at startup time and your XPA_METHOD is inet, the problem probably is related to
an incorrect Internet configuration. This can be confirmed by using the unix method or (usually) the localhost method. You can use these
alternate methods if other hosts do not need access to the XPA server.
