NAME

6       mscan_selinux - Security Enhanced Linux Policy for the mscan processes
7

DESCRIPTION

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

ENTRYPOINTS

23       The mscan_t SELinux type can be entered via the mscan_exec_t file type.
24
25       The default entrypoint paths for the mscan_t domain are the following:
26
27       /usr/sbin/MailScanner
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       mscan policy is very flexible allowing users to setup their mscan  pro‐
37       cesses in as secure a method as possible.
38
39       The following process types are defined for mscan:
40
41       mscan_t
42
43       Note:  semanage  permissive  -a mscan_t can be used to make the process
44       type mscan_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.   mscan
51       policy is extremely flexible and has several booleans that allow you to
52       manipulate the policy and run mscan with the tightest access possible.
53
54
55
56       If you want to dontaudit all  daemons  scheduling  requests  (setsched,
57       sys_nice),  you  must turn on the daemons_dontaudit_scheduling boolean.
58       Enabled by default.
59
60       setsebool -P daemons_dontaudit_scheduling 1
61
62
63
64       If you want to allow all domains to execute in fips_mode, you must turn
65       on the fips_mode boolean. Enabled by default.
66
67       setsebool -P fips_mode 1
68
69
70
71       If  you  want  to  allow  system  to run with NIS, you must turn on the
72       nis_enabled boolean. Disabled by default.
73
74       setsebool -P nis_enabled 1
75
76
77

MANAGED FILES

79       The SELinux process type mscan_t can manage files labeled with the fol‐
80       lowing  file  types.   The paths listed are the default paths for these
81       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

159       SELinux requires files to have an extended attribute to define the file
160       type.
161
162       You can see the context of a file using the -Z option to ls
163
164       Policy  governs  the  access  confined  processes  have to these files.
165       SELinux mscan policy is very flexible allowing  users  to  setup  their
166       mscan processes in as secure a method as possible.
167
168       STANDARD FILE CONTEXT
169
170       SELinux  defines the file context types for the mscan, if you wanted to
171       store files with these types in a different paths, you need to  execute
172       the  semanage  command  to  specify alternate labeling and then use re‐
173       storecon to put the labels on disk.
174
175       semanage fcontext -a -t mscan_exec_t '/srv/mscan/content(/.*)?'
176       restorecon -R -v /srv/mymscan_content
177
178       Note: SELinux often uses regular expressions  to  specify  labels  that
179       match multiple files.
180
181       The following file types are defined for mscan:
182
183
184
185       mscan_etc_t
186
187       - Set files with the mscan_etc_t type, if you want to store mscan files
188       in the /etc directories.
189
190
191       Paths:
192            /etc/MailScanner(/.*)?,  /etc/sysconfig/MailScanner,  /etc/syscon‐
193            fig/update_spamassassin
194
195
196       mscan_exec_t
197
198       -  Set  files  with the mscan_exec_t type, if you want to transition an
199       executable to the mscan_t domain.
200
201
202
203       mscan_initrc_exec_t
204
205       - Set files with the mscan_initrc_exec_t type, if you want  to  transi‐
206       tion an executable to the mscan_initrc_t domain.
207
208
209
210       mscan_spool_t
211
212       - Set files with the mscan_spool_t type, if you want to store the mscan
213       files under the /var/spool directory.
214
215
216
217       mscan_tmp_t
218
219       - Set files with the mscan_tmp_t type, if you want to store mscan  tem‐
220       porary files in the /tmp directories.
221
222
223
224       mscan_var_run_t
225
226       -  Set  files  with  the mscan_var_run_t type, if you want to store the
227       mscan files under the /run or /var/run directory.
228
229
230
231       Note: File context can be temporarily modified with the chcon  command.
232       If  you want to permanently change the file context you need to use the
233       semanage fcontext command.  This will modify the SELinux labeling data‐
234       base.  You will need to use restorecon to apply the labels.
235
236

COMMANDS

238       semanage  fcontext  can also be used to manipulate default file context
239       mappings.
240
241       semanage permissive can also be used to manipulate  whether  or  not  a
242       process type is permissive.
243
244       semanage  module can also be used to enable/disable/install/remove pol‐
245       icy modules.
246
247       semanage boolean can also be used to manipulate the booleans
248
249
250       system-config-selinux is a GUI tool available to customize SELinux pol‐
251       icy settings.
