| PackageDescription | SELinux core policy utilities
Security-enhanced Linux is a patch of the Linux® kernel and a number
of utilities with enhanced security functionality designed to add
mandatory access controls to Linux. The Security-enhanced Linux
kernel contains new architectural components originally developed to
improve the security of the Flask operating system. These
architectural components provide general support for the enforcement
of many kinds of mandatory access control policies, including those
based on the concepts of Type Enforcement®, Role-based Access Control,
and Multi-level Security.
.
This package contains the core policy utilities that are required
for basic operation of an SELinux system. These utilities include
load_policy to load policies, setfiles to label filesystems, newrole
to switch roles, run_init to run /etc/init.d scripts in the proper
context, and restorecond to restore contexts of files that often get the
wrong context.
.
It also includes the mcstransd to map a maching readable sensitivity label to
a human readable form. The sensitivity label is comprised of a sensitivity
level (always s0 for MCS and anything from s0 to s15 for MLS) and a set of
categories. A ranged sensitivity label will have a low level and a high level
where the high level will dominate the low level. Categories are numbered
from c0 to c1023. Names such as s0 and c1023 and not easily readable by
humans, so mcstransd translated them to human readable labels such as
SystemLow and SystemHigh. |
