10 This manual page describes SELinux policy booleans. The SELinux pol‐
11 icy can include conditional rules that are enabled or disabled based on
12 the current values of a set of policy booleans. These policy booleans
13 allow runtime modification of the security policy without having to
14 load a new policy.
15
16 For example, the boolean httpd_enable_cgi allows the httpd daemon to
17 run cgi scripts if it is enabled. If the administrator does not want
18 to allow execution of cgi scripts, he can simply disable this boolean
19 value.
20
21 The policy defines a default value for each boolean, typically false.
22 These default values can be overridden via local settings created via
23 the setsebool(8) utility, using -P to make the setting persistent
24 across reboots. The system-config-securitylevel tool provides a graph‐
25 ical interface for altering the settings. The load_policy(8) program
26 will preserve current boolean settings upon a policy reload by default,
27 or can optionally reset booleans to the boot-time defaults via the -b
28 option.
29
30 Boolean values can be listed by using the getsebool(8) utility and
31 passing it the -a option.
32
33 Boolean values can also be changed at runtime via the setsebool(8)
34 utility or the togglesebool(8) utility. By default, these utilities
35 only change the current boolean value and do not affect the persistent
36 settings, unless the -P option is used to setsebool.
