6 spamc_selinux - Security Enhanced Linux Policy for the spamc processes
7
9 Security-Enhanced Linux secures the spamc processes via flexible manda‐
10 tory access control.
11
12 The spamc processes execute with the spamc_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 spamc_t
19
20
21
23 The spamc_t SELinux type can be entered via the spamc_exec_t file type.
24
25 The default entrypoint paths for the spamc_t domain are the following:
26
27 /usr/bin/razor.*, /usr/bin/spamc, /usr/bin/pyzor, /usr/bin/sa-learn,
28 /usr/bin/spamassassin
29
31 SELinux defines process types (domains) for each process running on the
32 system
33
34 You can see the context of a process using the -Z option to ps
35
36 Policy governs the access confined processes have to files. SELinux
37 spamc policy is very flexible allowing users to setup their spamc pro‐
38 cesses in as secure a method as possible.
39
40 The following process types are defined for spamc:
41
42 spamc_t
43
44 Note: semanage permissive -a spamc_t can be used to make the process
45 type spamc_t permissive. SELinux does not deny access to permissive
46 process types, but the AVC (SELinux denials) messages are still gener‐
47 ated.
48
49
51 SELinux policy is customizable based on least access required. spamc
52 policy is extremely flexible and has several booleans that allow you to
53 manipulate the policy and run spamc with the tightest access possible.

150 The SELinux process type spamc_t can manage files labeled with the fol‐
151 lowing file types. The paths listed are the default paths for these
152 file types. Note the processes UID still need to have DAC permissions.

221 SELinux requires files to have an extended attribute to define the file
222 type.
223
224 You can see the context of a file using the -Z option to ls
225
226 Policy governs the access confined processes have to these files.
227 SELinux spamc policy is very flexible allowing users to setup their
228 spamc processes in as secure a method as possible.
229
230 STANDARD FILE CONTEXT
231
232 SELinux defines the file context types for the spamc, if you wanted to
233 store files with these types in a diffent paths, you need to execute
234 the semanage command to sepecify alternate labeling and then use
235 restorecon to put the labels on disk.
236
237 semanage fcontext -a -t spamc_tmp_t '/srv/myspamc_content(/.*)?'
238 restorecon -R -v /srv/myspamc_content
239
240 Note: SELinux often uses regular expressions to specify labels that
241 match multiple files.
242
243 The following file types are defined for spamc:
244
245
246
247 spamc_exec_t
248
249 - Set files with the spamc_exec_t type, if you want to transition an
250 executable to the spamc_t domain.
251
252
253 Paths:
254 /usr/bin/razor.*, /usr/bin/spamc, /usr/bin/pyzor, /usr/bin/sa-
255 learn, /usr/bin/spamassassin
256
257
258 spamc_home_t
259
260 - Set files with the spamc_home_t type, if you want to store spamc
261 files in the users home directory.
262
263
264 Paths:
265 /root/.razor(/.*)?, /root/.pyzor(/.*)?, /root/.spamd(/.*)?,
266 /root/.spamassassin(/.*)?, /home/[^/]*/.razor(/.*)?,
267 /home/[^/]*/.pyzor(/.*)?, /home/[^/]*/.spamd(/.*)?,
268 /home/[^/]*/.spamassassin(/.*)?, /home/staff/.razor(/.*)?,
269 /home/staff/.pyzor(/.*)?, /home/staff/.spamd(/.*)?,
270 /home/staff/.spamassassin(/.*)?
271
272
273 spamc_tmp_t
274
275 - Set files with the spamc_tmp_t type, if you want to store spamc tem‐
276 porary files in the /tmp directories.
277
278
279
280 Note: File context can be temporarily modified with the chcon command.
281 If you want to permanently change the file context you need to use the
282 semanage fcontext command. This will modify the SELinux labeling data‐
283 base. You will need to use restorecon to apply the labels.
284
285
287 semanage fcontext can also be used to manipulate default file context
288 mappings.
289
290 semanage permissive can also be used to manipulate whether or not a
291 process type is permissive.
292
293 semanage module can also be used to enable/disable/install/remove pol‐
294 icy modules.
295
296 semanage boolean can also be used to manipulate the booleans
297
298
299 system-config-selinux is a GUI tool available to customize SELinux pol‐
300 icy settings.
