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
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.

PORT TYPES

150       SELinux defines port types to represent TCP and UDP ports.
151
152       You  can  see  the  types associated with a port by using the following
153       command:
154
155       semanage port -l
156
157
158       Policy governs the access  confined  processes  have  to  these  ports.
159       SELinux  dspam  policy  is  very flexible allowing users to setup their
160       dspam processes in as secure a method as possible.
161
162       The following port types are defined for dspam:
163
164
165       dspam_port_t
166
167
168
169       Default Defined Ports:
170                 tcp 10026
171

MANAGED FILES

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

FILE CONTEXTS

252       SELinux requires files to have an extended attribute to define the file
253       type.
254
255       You can see the context of a file using the -Z option to ls
256
257       Policy  governs  the  access  confined  processes  have to these files.
258       SELinux dspam policy is very flexible allowing  users  to  setup  their
259       dspam processes in as secure a method as possible.
260
261       STANDARD FILE CONTEXT
262
263       SELinux  defines the file context types for the dspam, if you wanted to
264       store files with these types in a diffent paths, you  need  to  execute
265       the  semanage  command  to  sepecify  alternate  labeling  and then use
266       restorecon to put the labels on disk.
267
268       semanage fcontext -a -t dspam_var_run_t '/srv/mydspam_content(/.*)?'
269       restorecon -R -v /srv/mydspam_content
270
271       Note: SELinux often uses regular expressions  to  specify  labels  that
272       match multiple files.
273
274       The following file types are defined for dspam:
275
276
277
278       dspam_exec_t
279
280       -  Set  files  with the dspam_exec_t type, if you want to transition an
281       executable to the dspam_t domain.
282
283
284
285       dspam_initrc_exec_t
286
287       - Set files with the dspam_initrc_exec_t type, if you want  to  transi‐
288       tion an executable to the dspam_initrc_t domain.
289
290
291
292       dspam_log_t
293
294       - Set files with the dspam_log_t type, if you want to treat the data as
295       dspam log data, usually stored under the /var/log directory.
296
297
298
299       dspam_tmp_t
300
301       - Set files with the dspam_tmp_t type, if you want to store dspam  tem‐
302       porary files in the /tmp directories.
303
304
305
306       dspam_var_lib_t
307
308       -  Set  files  with  the dspam_var_lib_t type, if you want to store the
309       dspam files under the /var/lib directory.
310
311
312
313       dspam_var_run_t
314
315       - Set files with the dspam_var_run_t type, if you  want  to  store  the
316       dspam files under the /run or /var/run directory.
317
318
319
320       Note:  File context can be temporarily modified with the chcon command.
321       If you want to permanently change the file context you need to use  the
322       semanage fcontext command.  This will modify the SELinux labeling data‐
323       base.  You will need to use restorecon to apply the labels.
324
325

COMMANDS

327       semanage fcontext can also be used to manipulate default  file  context
328       mappings.
329
330       semanage  permissive  can  also  be used to manipulate whether or not a
331       process type is permissive.
332
333       semanage module can also be used to enable/disable/install/remove  pol‐
334       icy modules.
335
336       semanage port can also be used to manipulate the port definitions
337
338       semanage boolean can also be used to manipulate the booleans
339
340
341       system-config-selinux is a GUI tool available to customize SELinux pol‐
342       icy settings.
