6 setsebool_selinux - Security Enhanced Linux Policy for the setsebool
7 processes
8
10 Security-Enhanced Linux secures the setsebool processes via flexible
11 mandatory access control.
12 The setsebool processes execute with the setsebool_t SELinux type. You
14 can check if you have these processes running by executing the ps com‐
15 mand with the -Z qualifier.
16 For example:
18 ps -eZ | grep setsebool_t
20
24 The setsebool_t SELinux type can be entered via the setsebool_exec_t
25 file type.
26 The default entrypoint paths for the setsebool_t domain are the follow‐
28 ing:
29 /usr/sbin/setsebool
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 Policy governs the access confined processes have to files. SELinux
39 setsebool policy is very flexible allowing users to setup their setse‐
40 bool processes in as secure a method as possible.
41 The following process types are defined for setsebool:
43 setsebool_t
45 Note: semanage permissive -a setsebool_t can be used to make the
47 process type setsebool_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
53 SELinux policy is customizable based on least access required. setse‐
54 bool policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run setsebool with the tightest access
56 possible.
57 If you want to allow all daemons the ability to read/write terminals,
61 you must turn on the allow_daemons_use_tty boolean. Disabled by
62 default.
63 setsebool -P allow_daemons_use_tty 1
65 If you want to allow all domains to use other domains file descriptors,
69 you must turn on the allow_domain_fd_use boolean. Enabled by default.
70 setsebool -P allow_domain_fd_use 1
72 If you want to allow confined applications to run with kerberos, you
76 must turn on the allow_kerberos boolean. Enabled by default.
77 setsebool -P allow_kerberos 1
79 If you want to allow sysadm to debug or ptrace all processes, you must
83 turn on the allow_ptrace boolean. Disabled by default.
84 setsebool -P allow_ptrace 1
86 If you want to allow system to run with NIS, you must turn on the
90 allow_ypbind boolean. Disabled by default.
91 setsebool -P allow_ypbind 1
93 If you want to allow all domains to have the kernel load modules, you
97 must turn on the domain_kernel_load_modules boolean. Disabled by
98 default.
99 setsebool -P domain_kernel_load_modules 1
101 If you want to allow all domains to execute in fips_mode, you must turn
105 on the fips_mode boolean. Enabled by default.
106 setsebool -P fips_mode 1
108 If you want to enable reading of urandom for all domains, you must turn
112 on the global_ssp boolean. Disabled by default.
113 setsebool -P global_ssp 1
115 If you want to allow confined applications to use nscd shared memory,
119 you must turn on the nscd_use_shm boolean. Enabled by default.
120 setsebool -P nscd_use_shm 1
122 If you want to boolean to determine whether the system permits loading
126 policy, setting enforcing mode, and changing boolean values. Set this
127 to true and you have to reboot to set it back, you must turn on the
128 secure_mode_policyload boolean. Disabled by default.
129 setsebool -P secure_mode_policyload 1

135 The SELinux process type setsebool_t can manage files labeled with the
136 following file types. The paths listed are the default paths for these
137 file types. Note the processes UID still need to have DAC permissions.

204 SELinux requires files to have an extended attribute to define the file
205 type.
206 You can see the context of a file using the -Z option to ls
208 Policy governs the access confined processes have to these files.
210 SELinux setsebool policy is very flexible allowing users to setup their
211 setsebool processes in as secure a method as possible.
212 The following file types are defined for setsebool:
214 setsebool_exec_t
218 - Set files with the setsebool_exec_t type, if you want to transition
220 an executable to the setsebool_t domain.
221 Note: File context can be temporarily modified with the chcon command.
225 If you want to permanently change the file context you need to use the
226 semanage fcontext command. This will modify the SELinux labeling data‐
227 base. You will need to use restorecon to apply the labels.
228
231 semanage fcontext can also be used to manipulate default file context
232 mappings.
233 semanage permissive can also be used to manipulate whether or not a
235 process type is permissive.
236 semanage module can also be used to enable/disable/install/remove pol‐
238 icy modules.
239 semanage boolean can also be used to manipulate the booleans
241 system-config-selinux is a GUI tool available to customize SELinux pol‐
244 icy settings.
