NAME

       booleans - Policy booleans enable runtime customization of SELinux policy.

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 via local settings created
       via the setsebool(8) utility, using -P to make the setting persistent across reboots.   The  system-config-securitylevel  tool  provides  a
       graphical  interface  for altering the settings.  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.	By default, these  utilities  only
       change the current boolean value and do not affect the persistent settings, unless the -P option is used to setsebool.
