NAME

6       certmaster_selinux  - Security Enhanced Linux Policy for the certmaster
7       processes
8

DESCRIPTION

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

ENTRYPOINTS

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

PROCESS TYPES

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

BOOLEANS

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.

PORT TYPES

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

MANAGED FILES

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.

FILE CONTEXTS

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

COMMANDS

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.
