NAME

6       munin_selinux - Security Enhanced Linux Policy for the munin processes
7

DESCRIPTION

9       Security-Enhanced Linux secures the munin processes via flexible manda‐
10       tory access control.
11
12       The munin processes execute with the  munin_t  SELinux  type.  You  can
13       check  if  you have these processes running by executing the ps command
14       with the -Z qualifier.
15
16       For example:
17
18       ps -eZ | grep munin_t
19
20
21

ENTRYPOINTS

23       The munin_t SELinux type can be entered via the munin_exec_t file type.
24
25       The default entrypoint paths for the munin_t domain are the following:
26
27       /usr/bin/munin-.*, /usr/sbin/munin-.*, /usr/share/munin/munin-.*
28

PROCESS TYPES

30       SELinux defines process types (domains) for each process running on the
31       system
32
33       You can see the context of a process using the -Z option to ps
34
35       Policy  governs  the  access confined processes have to files.  SELinux
36       munin policy is very flexible allowing users to setup their munin  pro‐
37       cesses in as secure a method as possible.
38
39       The following process types are defined for munin:
40
41       munin_t, munin_script_t
42
43       Note:  semanage  permissive  -a munin_t can be used to make the process
44       type munin_t permissive. SELinux does not  deny  access  to  permissive
45       process  types, but the AVC (SELinux denials) messages are still gener‐
46       ated.
47
48

BOOLEANS

50       SELinux policy is customizable based on least access  required.   munin
51       policy is extremely flexible and has several booleans that allow you to
52       manipulate the policy and run munin with the tightest access possible.

PORT TYPES

167       SELinux defines port types to represent TCP and UDP ports.
168
169       You can see the types associated with a port  by  using  the  following
170       command:
171
172       semanage port -l
173
174
175       Policy  governs  the  access  confined  processes  have to these ports.
176       SELinux munin policy is very flexible allowing  users  to  setup  their
177       munin processes in as secure a method as possible.
178
179       The following port types are defined for munin:
180
181
182       munin_port_t
183
184
185
186       Default Defined Ports:
187                 tcp 4949
188                 udp 4949
189

MANAGED FILES

191       The SELinux process type munin_t can manage files labeled with the fol‐
192       lowing file types.  The paths listed are the default  paths  for  these
193       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

251       SELinux requires files to have an extended attribute to define the file
252       type.
253
254       You can see the context of a file using the -Z option to ls
255
256       Policy governs the access  confined  processes  have  to  these  files.
257       SELinux  munin  policy  is  very flexible allowing users to setup their
258       munin processes in as secure a method as possible.
259
260       EQUIVALENCE DIRECTORIES
261
262
263       munin policy stores data with multiple  different  file  context  types
264       under  the  /var/www/html/munin  directory.  If you would like to store
265       the data in a different directory you can use the semanage  command  to
266       create  an equivalence mapping.  If you wanted to store this data under
267       the /srv dirctory you would execute the following command:
268
269       semanage fcontext -a -e /var/www/html/munin /srv/munin
270       restorecon -R -v /srv/munin
271
272       munin policy stores data with multiple  different  file  context  types
273       under  the  /var/lib/munin  directory.   If you would like to store the
274       data in a different directory you can use the semanage command to  cre‐
275       ate an equivalence mapping.  If you wanted to store this data under the
276       /srv dirctory you would execute the following command:
277
278       semanage fcontext -a -e /var/lib/munin /srv/munin
279       restorecon -R -v /srv/munin
280
281       STANDARD FILE CONTEXT
282
283       SELinux defines the file context types for the munin, if you wanted  to
284       store  files  with  these types in a diffent paths, you need to execute
285       the semanage command  to  sepecify  alternate  labeling  and  then  use
286       restorecon to put the labels on disk.
287
288       semanage fcontext -a -t munin_var_run_t '/srv/mymunin_content(/.*)?'
289       restorecon -R -v /srv/mymunin_content
290
291       Note:  SELinux  often  uses  regular expressions to specify labels that
292       match multiple files.
293
294       The following file types are defined for munin:
295
296

326
327
328
329       munin_initrc_exec_t

342
343       munin_plugin_state_t
344
345       - Set files with the munin_plugin_state_t type, if you  want  to  treat
346       the files as munin plugin state data.
347
348
349
350       munin_ra_content_t
351
352       -  Set files with the munin_ra_content_t type, if you want to treat the

371            /var/www/cgi-bin/munin.*,               /var/www/html/cgi/munin.*,
372            /var/www/html/munin/cgi(/.*)?

400
401
402
403       Note:  File context can be temporarily modified with the chcon command.
404       If you want to permanently change the file context you need to use  the
405       semanage fcontext command.  This will modify the SELinux labeling data‐
406       base.  You will need to use restorecon to apply the labels.
407
408

COMMANDS

410       semanage fcontext can also be used to manipulate default  file  context
411       mappings.
412
413       semanage  permissive  can  also  be used to manipulate whether or not a
414       process type is permissive.
415
416       semanage module can also be used to enable/disable/install/remove  pol‐
417       icy modules.
418
419       semanage port can also be used to manipulate the port definitions
420
421       semanage boolean can also be used to manipulate the booleans
422
423
424       system-config-selinux is a GUI tool available to customize SELinux pol‐
425       icy settings.
