6 certmaster_selinux - Security Enhanced Linux Policy for the certmaster
7 processes
8
10 Security-Enhanced Linux secures the certmaster processes via flexible
11 mandatory access control.
12
13 The certmaster processes execute with the certmaster_t SELinux type.
14 You can check if you have these processes running by executing the ps
15 command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep certmaster_t
20
21
22
24 The certmaster_t SELinux type can be entered via the certmaster_exec_t
25 file type.
26
27 The default entrypoint paths for the certmaster_t domain are the fol‐
28 lowing:
29
30 /usr/bin/certmaster
31
33 SELinux defines process types (domains) for each process running on the
34 system
35
36 You can see the context of a process using the -Z option to ps
37
38 Policy governs the access confined processes have to files. SELinux
39 certmaster policy is very flexible allowing users to setup their cert‐
40 master processes in as secure a method as possible.
41
42 The following process types are defined for certmaster:
43
44 certmaster_t
45
46 Note: semanage permissive -a certmaster_t can be used to make the
47 process type certmaster_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
51
53 SELinux policy is customizable based on least access required. cert‐
54 master policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run certmaster with the tightest
56 access possible.

154 SELinux defines port types to represent TCP and UDP ports.
155
156 You can see the types associated with a port by using the following
157 command:
158
159 semanage port -l
160
161
162 Policy governs the access confined processes have to these ports.
163 SELinux certmaster policy is very flexible allowing users to setup
164 their certmaster processes in as secure a method as possible.
165
166 The following port types are defined for certmaster:
167
168
169 certmaster_port_t
170
171
172
173 Default Defined Ports:
174 tcp 51235
175
177 The SELinux process type certmaster_t can manage files labeled with the
178 following file types. The paths listed are the default paths for these
179 file types. Note the processes UID still need to have DAC permissions.

267 SELinux requires files to have an extended attribute to define the file
268 type.
269
270 You can see the context of a file using the -Z option to ls
271
272 Policy governs the access confined processes have to these files.
273 SELinux certmaster policy is very flexible allowing users to setup
274 their certmaster processes in as secure a method as possible.
275
276 STANDARD FILE CONTEXT
277
278 SELinux defines the file context types for the certmaster, if you
279 wanted to store files with these types in a diffent paths, you need to
280 execute the semanage command to sepecify alternate labeling and then
281 use restorecon to put the labels on disk.
282
283 semanage fcontext -a -t certmaster_var_run_t '/srv/mycertmaster_con‐
284 tent(/.*)?'
285 restorecon -R -v /srv/mycertmaster_content
286
287 Note: SELinux often uses regular expressions to specify labels that
288 match multiple files.
289
290 The following file types are defined for certmaster:
291
292
293
294 certmaster_etc_rw_t
295
296 - Set files with the certmaster_etc_rw_t type, if you want to treat the
297 files as certmaster etc read/write content.
298
299
300
301 certmaster_exec_t
302
303 - Set files with the certmaster_exec_t type, if you want to transition
304 an executable to the certmaster_t domain.
305
306
307
308 certmaster_initrc_exec_t
309
310 - Set files with the certmaster_initrc_exec_t type, if you want to
311 transition an executable to the certmaster_initrc_t domain.
312
313
314
315 certmaster_var_lib_t
316
317 - Set files with the certmaster_var_lib_t type, if you want to store
318 the certmaster files under the /var/lib directory.
319
320
321
322 certmaster_var_log_t
323
324 - Set files with the certmaster_var_log_t type, if you want to treat
325 the data as certmaster var log data, usually stored under the /var/log
326 directory.
327
328
329
330 certmaster_var_run_t
331
332 - Set files with the certmaster_var_run_t type, if you want to store
333 the certmaster files under the /run or /var/run directory.
334
335
336
337 Note: File context can be temporarily modified with the chcon command.
338 If you want to permanently change the file context you need to use the
339 semanage fcontext command. This will modify the SELinux labeling data‐
340 base. You will need to use restorecon to apply the labels.
341
342
344 semanage fcontext can also be used to manipulate default file context
345 mappings.
346
347 semanage permissive can also be used to manipulate whether or not a
348 process type is permissive.
349
350 semanage module can also be used to enable/disable/install/remove pol‐
351 icy modules.
352
353 semanage port can also be used to manipulate the port definitions
354
355 semanage boolean can also be used to manipulate the booleans
356
357
358 system-config-selinux is a GUI tool available to customize SELinux pol‐
359 icy settings.
