#
# See /etc/permissions for general hints on how to use this file.
#
# /etc/permissions.secure is designed for the use in a multi-user and
# networked installation. Most privileged file modes are disabled here.
# Many programs that still have their suid- or sgid-modes have had their
# security problems in the past already.
# The primary target of this configuration is to make the basic things
# such as changing passwords, the basic networking programs as well as
# some of the all-day work programs properly function for the unprivileged
# user. The dial-out packages are executable for users belonging to the
# "dialout" group - therefore, these users are to be treated "privileged".
# Packages such as (remote-) batch queueing systems, games, programs for
# the linux text console, everything linked against OOP libraries and
# most other exotic utilities are turned into unprivileged binary files
# in order for them not to cause any security problems if one or more of
# the programs turn out to have buffer overruns or otherwise locally
# exploitable programming errors.
# This file is not designed to make your system as closed and as restrictive
# as at all possible. In many cases, restricted access to a configuration
# file is of no use since the data used can be obtained from the /proc file
# system or interface configuration as well. Also, system programs such as
# /sbin/ifconfig or /sbin/route are not changed because nosey users can
# bring their own. "Security by obscurity" will add any significant
# security-related advantage to the system. Keep in mind that curiosity
# is a major motivation for your users to try to see behind the curtain.
#
# If you need the functionality of a program that usually runs as a
# privileged user, then use it as root, or, if you are not root, ask your
# system administrator for advice. In many cases, adding a user to the
# "trusted" group gives her access to the resources that are not accessible
# any more if the admin chose to select "secure" as the permissions default.
#
# Please make use of the diff program to see the differences between the
# permissions.easy and permissions.secure files if things don't work as
# they should and you suspect a permission or privilege problem.
# The word "easy" is a reference for the /etc/permissions.easy file.
#
# As usual, these settings are "suggested". If you feel so inclined,
# please feel free to change the modes in this files, but keep a log
# of your changes for future reference.
# Please always keep in mind that your system listens on network sockets
# in the default configuration. Change this by disabling the services that
# you do not need or by restricting access to them using packet filters
# or tcp wrappers (see hosts_access(5)) to gain a higher level of security
# in your system.
