NAME

6       dspam_selinux - Security Enhanced Linux Policy for the dspam processes
7

DESCRIPTION

9       Security-Enhanced Linux secures the dspam processes via flexible manda‐
10       tory access control.
11
12       The dspam processes execute with the  dspam_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 dspam_t
19
20
21

ENTRYPOINTS

23       The dspam_t SELinux type can be entered via the dspam_exec_t file type.
24
25       The default entrypoint paths for the dspam_t domain are the following:
26
27       /usr/bin/dspam
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       dspam policy is very flexible allowing users to setup their dspam  pro‐
37       cesses in as secure a method as possible.
38
39       The following process types are defined for dspam:
40
41       dspam_t, dspam_script_t
42
43       Note:  semanage  permissive  -a dspam_t can be used to make the process
44       type dspam_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.   dspam
51       policy is extremely flexible and has several booleans that allow you to
52       manipulate the policy and run dspam with the tightest access possible.

MANAGED FILES

175       The SELinux process type dspam_t can manage files labeled with the fol‐
176       lowing  file  types.   The paths listed are the default paths for these
177       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

224       SELinux requires files to have an extended attribute to define the file
225       type.
226
227       You can see the context of a file using the -Z option to ls
228
229       Policy  governs  the  access  confined  processes  have to these files.
230       SELinux dspam policy is very flexible allowing  users  to  setup  their
231       dspam processes in as secure a method as possible.
232
233       EQUIVALENCE DIRECTORIES
234
235
236       dspam  policy  stores  data  with multiple different file context types
237       under the /var/lib/dspam directory.  If you would  like  to  store  the
238       data  in a different directory you can use the semanage command to cre‐
239       ate an equivalence mapping.  If you wanted to store this data under the
240       /srv dirctory you would execute the following command:
241
242       semanage fcontext -a -e /var/lib/dspam /srv/dspam
243       restorecon -R -v /srv/dspam
244
245       STANDARD FILE CONTEXT
246
247       SELinux  defines the file context types for the dspam, if you wanted to
248       store files with these types in a diffent paths, you  need  to  execute
249       the  semanage  command  to  sepecify  alternate  labeling  and then use
250       restorecon to put the labels on disk.
251
252       semanage fcontext -a -t dspam_var_run_t '/srv/mydspam_content(/.*)?'
253       restorecon -R -v /srv/mydspam_content
254
255       Note: SELinux often uses regular expressions  to  specify  labels  that
256       match multiple files.
257
258       The following file types are defined for dspam:
259
260
261
262       dspam_content_t
263
264       -  Set  files  with  the dspam_content_t type, if you want to treat the
265       files as dspam content.
266
267
268
269       dspam_exec_t
270
271       - Set files with the dspam_exec_t type, if you want  to  transition  an
272       executable to the dspam_t domain.
273
274
275
276       dspam_htaccess_t
277
278       -  Set  files  with the dspam_htaccess_t type, if you want to treat the
279       file as a dspam access file.
280
281
282
283       dspam_initrc_exec_t
284
285       - Set files with the dspam_initrc_exec_t type, if you want  to  transi‐
286       tion an executable to the dspam_initrc_t domain.
287
288
289
290       dspam_log_t
291
292       - Set files with the dspam_log_t type, if you want to treat the data as
293       dspam log data, usually stored under the /var/log directory.
294
295
296
297       dspam_ra_content_t
298
299       - Set files with the dspam_ra_content_t type, if you want to treat  the
300       files as dspam  read/append content.
301
302
303
304       dspam_rw_content_t
305
306       -  Set files with the dspam_rw_content_t type, if you want to treat the
307       files as dspam read/write content.
308
309
310
311       dspam_script_exec_t
312
313       - Set files with the dspam_script_exec_t type, if you want  to  transi‐
314       tion an executable to the dspam_script_t domain.
315
316
317       Paths:
318            /var/www/dspam/.*.cgi, /usr/share/dspam-web/dspam.cgi
319
320
321       dspam_var_lib_t
322
323       -  Set  files  with  the dspam_var_lib_t type, if you want to store the
324       dspam files under the /var/lib directory.
325
326
327
328       dspam_var_run_t
329
330       - Set files with the dspam_var_run_t type, if you  want  to  store  the
331       dspam files under the /run or /var/run directory.
332
333
334
335       Note:  File context can be temporarily modified with the chcon command.
336       If you want to permanently change the file context you need to use  the
337       semanage fcontext command.  This will modify the SELinux labeling data‐
338       base.  You will need to use restorecon to apply the labels.
339
340

COMMANDS

342       semanage fcontext can also be used to manipulate default  file  context
343       mappings.
344
345       semanage  permissive  can  also  be used to manipulate whether or not a
346       process type is permissive.
347
348       semanage module can also be used to enable/disable/install/remove  pol‐
349       icy modules.
350
351       semanage boolean can also be used to manipulate the booleans
352
353
354       system-config-selinux is a GUI tool available to customize SELinux pol‐
355       icy settings.
