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 allow all domains to execute in fips_mode, you must turn
57       on the fips_mode boolean. Enabled by default.
58
59       setsebool -P fips_mode 1
60
61
62
63       If  you  want  to  allow  system  to run with NIS, you must turn on the
64       nis_enabled boolean. Disabled by default.
65
66       setsebool -P nis_enabled 1
67

MANAGED FILES

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

FILE CONTEXTS

151       SELinux requires files to have an extended attribute to define the file
152       type.
153
154       You can see the context of a file using the -Z option to ls
155
156       Policy  governs  the  access  confined  processes  have to these files.
157       SELinux mscan policy is very flexible allowing  users  to  setup  their
158       mscan processes in as secure a method as possible.
159
160       STANDARD FILE CONTEXT
161
162       SELinux  defines the file context types for the mscan, if you wanted to
163       store files with these types in a diffent paths, you  need  to  execute
164       the  semanage  command  to  specify alternate labeling and then use re‐
165       storecon to put the labels on disk.
166
167       semanage fcontext -a -t mscan_var_run_t '/srv/mymscan_content(/.*)?'
168       restorecon -R -v /srv/mymscan_content
169
170       Note: SELinux often uses regular expressions  to  specify  labels  that
171       match multiple files.
172
173       The following file types are defined for mscan:
174
175
176
177       mscan_etc_t
178
179       - Set files with the mscan_etc_t type, if you want to store mscan files
180       in the /etc directories.
181
182
183       Paths:
184            /etc/MailScanner(/.*)?,  /etc/sysconfig/MailScanner,  /etc/syscon‐
185            fig/update_spamassassin
186
187
188       mscan_exec_t
189
190       -  Set  files  with the mscan_exec_t type, if you want to transition an
191       executable to the mscan_t domain.
192
193
194
195       mscan_initrc_exec_t
196
197       - Set files with the mscan_initrc_exec_t type, if you want  to  transi‐
198       tion an executable to the mscan_initrc_t domain.
199
200
201
202       mscan_spool_t
203
204       - Set files with the mscan_spool_t type, if you want to store the mscan
205       files under the /var/spool directory.
206
207
208
209       mscan_tmp_t
210
211       - Set files with the mscan_tmp_t type, if you want to store mscan  tem‐
212       porary files in the /tmp directories.
213
214
215
216       mscan_var_run_t
217
218       -  Set  files  with  the mscan_var_run_t type, if you want to store the
219       mscan files under the /run or /var/run directory.
220
221
222
223       Note: File context can be temporarily modified with the chcon  command.
224       If  you want to permanently change the file context you need to use the
225       semanage fcontext command.  This will modify the SELinux labeling data‐
226       base.  You will need to use restorecon to apply the labels.
227
228

COMMANDS

230       semanage  fcontext  can also be used to manipulate default file context
231       mappings.
232
233       semanage permissive can also be used to manipulate  whether  or  not  a
234       process type is permissive.
235
236       semanage  module can also be used to enable/disable/install/remove pol‐
237       icy modules.
238
239       semanage boolean can also be used to manipulate the booleans
240
241
242       system-config-selinux is a GUI tool available to customize SELinux pol‐
243       icy settings.
