By default, the ps command displays a process's arguments and the ps e command displays a process's environmental variables. You can prevent users from seeing the arguments and environmental variables of other users by enabling variables in the /etc/rc.config.common file as
follows:
# rcmgr -c set TBL_ARGUMENTS_DISABLE 1
# rcmgr -c set TBL_ENVIRONMENT_DISABLE 1
Root is always able to see other users' arguments and environment variables.
