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

133       SELinux requires files to have an extended attribute to define the file
134       type.
135
136       You can see the context of a file using the -Z option to ls
137
138       Policy  governs  the  access  confined  processes  have to these files.
139       SELinux mscan policy is very flexible allowing  users  to  setup  their
140       mscan processes in as secure a method as possible.
141
142       STANDARD FILE CONTEXT
143
144       SELinux  defines the file context types for the mscan, if you wanted to
145       store files with these types in a diffent paths, you  need  to  execute
146       the  semanage  command  to  sepecify  alternate  labeling  and then use
147       restorecon to put the labels on disk.
148
149       semanage fcontext -a -t mscan_var_run_t '/srv/mymscan_content(/.*)?'
150       restorecon -R -v /srv/mymscan_content
151
152       Note: SELinux often uses regular expressions  to  specify  labels  that
153       match multiple files.
154
155       The following file types are defined for mscan:
156
157
158
159       mscan_etc_t
160
161       - Set files with the mscan_etc_t type, if you want to store mscan files
162       in the /etc directories.
163
164
165       Paths:
166            /etc/MailScanner(/.*)?,  /etc/sysconfig/MailScanner,  /etc/syscon‐
167            fig/update_spamassassin
168
169
170       mscan_exec_t
171
172       -  Set  files  with the mscan_exec_t type, if you want to transition an
173       executable to the mscan_t domain.
174
175
176
177       mscan_initrc_exec_t
178
179       - Set files with the mscan_initrc_exec_t type, if you want  to  transi‐
180       tion an executable to the mscan_initrc_t domain.
181
182
183
184       mscan_spool_t
185
186       - Set files with the mscan_spool_t type, if you want to store the mscan
187       files under the /var/spool directory.
188
189
190
191       mscan_tmp_t
192
193       - Set files with the mscan_tmp_t type, if you want to store mscan  tem‐
194       porary files in the /tmp directories.
195
196
197
198       mscan_var_run_t
199
200       -  Set  files  with  the mscan_var_run_t type, if you want to store the
201       mscan files under the /run or /var/run directory.
202
203
204
205       Note: File context can be temporarily modified with the chcon  command.
206       If  you want to permanently change the file context you need to use the
207       semanage fcontext command.  This will modify the SELinux labeling data‐
208       base.  You will need to use restorecon to apply the labels.
209
210

COMMANDS

212       semanage  fcontext  can also be used to manipulate default file context
213       mappings.
214
215       semanage permissive can also be used to manipulate  whether  or  not  a
216       process type is permissive.
217
218       semanage  module can also be used to enable/disable/install/remove pol‐
219       icy modules.
220
221       semanage boolean can also be used to manipulate the booleans
222
223
224       system-config-selinux is a GUI tool available to customize SELinux pol‐
225       icy settings.
