NAME
booleans - Policy booleans enable runtime customization of SELinux pol-
icy.
DESCRIPTION
This manual page describes SELinux policy booleans.
The SELinux policy can include conditional rules that are enabled or
disabled based on the current values of a set of policy booleans.
These policy booleans allow runtime modification of the security policy
without having to load a new policy.
For example, the boolean httpd_enable_cgi allows the httpd daemon to
run cgi scripts if it is enabled. If the administrator does not want
to allow execution of cgi scripts, he can simply disable this boolean
value.
The policy defines a default value for each boolean, typically false.
These default values can be overridden at boot-time based on the set-
tings in the /etc/selinux/SELINUXTYPE/booleans file, where SELINUXTYPE
is the type of policy currently being run on the system as defined in
the /etc/selinux/config file. The system-config-securitylevel tool
provides an interface for altering the settings in this file. The
load_policy(8) program will preserve current boolean settings upon a
policy reload by default, or can optionally reset booleans to the boot-
time defaults via the -b option.
Boolean values can be listed by using the getsebool(8) utility and
passing it the -a option.
Boolean values can also be changed at runtime via the setsebool(8)
utility or the togglesebool utility. These utilities only change the
current boolean value and do not affect the boot-time settings.
