6 openwsman_selinux - Security Enhanced Linux Policy for the openwsman
7 processes
8
10 Security-Enhanced Linux secures the openwsman processes via flexible
11 mandatory access control.
12 The openwsman processes execute with the openwsman_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 openwsman_t
20
24 The openwsman_t SELinux type can be entered via the openwsman_exec_t
25 file type.
26 The default entrypoint paths for the openwsman_t domain are the follow‐
28 ing:
29 /usr/sbin/openwsmand
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 openwsman policy is very flexible allowing users to setup their openws‐
40 man processes in as secure a method as possible.
41 The following process types are defined for openwsman:
43 openwsman_t
45 Note: semanage permissive -a openwsman_t can be used to make the
47 process type openwsman_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. openws‐
54 man policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run openwsman with the tightest access
56 possible.
57 If you want to allow users to resolve user passwd entries directly from
61 ldap rather then using a sssd server, you must turn on the authlo‐
62 gin_nsswitch_use_ldap boolean. Disabled by default.

99 ean. Enabled by default.
100 setsebool -P deny_execmem 1

114 attribute file_type, you must turn on the domain_can_mmap_files bool‐
115 ean. Enabled by default.
116 setsebool -P domain_can_mmap_files 1
118 If you want to allow all domains write to kmsg_device, while kernel is
122 executed with systemd.log_target=kmsg parameter, you must turn on the
123 domain_can_write_kmsg boolean. Disabled by default.
124 setsebool -P domain_can_write_kmsg 1

197 secure_mode_policyload boolean. Enabled by default.
198 setsebool -P secure_mode_policyload 1
200 If you want to allow unconfined executables to make their heap memory
204 executable. Doing this is a really bad idea. Probably indicates a
205 badly coded executable, but could indicate an attack. This executable
206 should be reported in bugzilla, you must turn on the selin‐
207 uxuser_execheap boolean. Disabled by default.

235
239 The SELinux process type openwsman_t can manage files labeled with the
240 following file types. The paths listed are the default paths for these
241 file types. Note the processes UID still need to have DAC permissions.
242 file_type
244 all files on the system
246
249 SELinux requires files to have an extended attribute to define the file
250 type.
251 You can see the context of a file using the -Z option to ls
253 Policy governs the access confined processes have to these files.
255 SELinux openwsman policy is very flexible allowing users to setup their
256 openwsman processes in as secure a method as possible.
257 STANDARD FILE CONTEXT
259 SELinux defines the file context types for the openwsman, if you wanted
261 to store files with these types in a diffent paths, you need to execute
262 the semanage command to sepecify alternate labeling and then use
263 restorecon to put the labels on disk.
264 semanage fcontext -a -t openwsman_unit_file_t '/srv/myopenwsman_con‐
266 tent(/.*)?'
267 restorecon -R -v /srv/myopenwsman_content
268 Note: SELinux often uses regular expressions to specify labels that
270 match multiple files.
271 The following file types are defined for openwsman:
273 openwsman_exec_t
277 - Set files with the openwsman_exec_t type, if you want to transition
279 an executable to the openwsman_t domain.
280 openwsman_log_t
284 - Set files with the openwsman_log_t type, if you want to treat the
286 data as openwsman log data, usually stored under the /var/log direc‐
287 tory.
288 openwsman_run_t
292 - Set files with the openwsman_run_t type, if you want to treat the
294 files as openwsman run data.
295 openwsman_tmp_t
299 - Set files with the openwsman_tmp_t type, if you want to store openws‐
301 man temporary files in the /tmp directories.
302 openwsman_tmpfs_t
306 - Set files with the openwsman_tmpfs_t type, if you want to store open‐
308 wsman files on a tmpfs file system.
309 openwsman_unit_file_t
313 - Set files with the openwsman_unit_file_t type, if you want to treat
315 the files as openwsman unit content.
316 Note: File context can be temporarily modified with the chcon command.
320 If you want to permanently change the file context you need to use the
321 semanage fcontext command. This will modify the SELinux labeling data‐
322 base. You will need to use restorecon to apply the labels.
323
326 semanage fcontext can also be used to manipulate default file context
327 mappings.
328 semanage permissive can also be used to manipulate whether or not a
330 process type is permissive.
331 semanage module can also be used to enable/disable/install/remove pol‐
333 icy modules.
334 semanage boolean can also be used to manipulate the booleans
336 system-config-selinux is a GUI tool available to customize SELinux pol‐
339 icy settings.
