NAME
       booleans - Policy booleans enable runtime customization of SELinux policy

DESCRIPTION
       This  manual page describes SELinux policy booleans.   The SELinux policy can include con-
       ditional 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  val-
       ues 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  toggle-
       sebool(8)  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.
