6 mscan_selinux - Security Enhanced Linux Policy for the mscan processes
7
9 Security-Enhanced Linux secures the mscan processes via flexible manda‐
10 tory access control.
11 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 For example:
17 ps -eZ | grep mscan_t
19
23 The mscan_t SELinux type can be entered via the mscan_exec_t file type.
24 The default entrypoint paths for the mscan_t domain are the following:
26 /usr/sbin/MailScanner
28
30 SELinux defines process types (domains) for each process running on the
31 system
32 You can see the context of a process using the -Z option to ps
34 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 The following process types are defined for mscan:
40 mscan_t
42 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
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 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 setsebool -P fips_mode 1
60 If you want to allow system to run with NIS, you must turn on the
64 nis_enabled boolean. Disabled by default.
65 setsebool -P nis_enabled 1
67
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.

133 SELinux requires files to have an extended attribute to define the file
134 type.
135 You can see the context of a file using the -Z option to ls
137 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 STANDARD FILE CONTEXT
143 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 semanage fcontext -a -t mscan_var_run_t '/srv/mymscan_content(/.*)?'
150 restorecon -R -v /srv/mymscan_content
151 Note: SELinux often uses regular expressions to specify labels that
153 match multiple files.
154 The following file types are defined for mscan:
156 mscan_etc_t
160 - Set files with the mscan_etc_t type, if you want to store mscan files
162 in the /etc directories.
163 Paths:
166 /etc/MailScanner(/.*)?, /etc/sysconfig/MailScanner, /etc/syscon‐
167 fig/update_spamassassin
168 mscan_exec_t
171 - Set files with the mscan_exec_t type, if you want to transition an
173 executable to the mscan_t domain.
174 mscan_initrc_exec_t
178 - 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 mscan_spool_t
185 - Set files with the mscan_spool_t type, if you want to store the mscan
187 files under the /var/spool directory.
188 mscan_tmp_t
192 - Set files with the mscan_tmp_t type, if you want to store mscan tem‐
194 porary files in the /tmp directories.
195 mscan_var_run_t
199 - 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 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
212 semanage fcontext can also be used to manipulate default file context
213 mappings.
214 semanage permissive can also be used to manipulate whether or not a
216 process type is permissive.
217 semanage module can also be used to enable/disable/install/remove pol‐
219 icy modules.
220 semanage boolean can also be used to manipulate the booleans
222 system-config-selinux is a GUI tool available to customize SELinux pol‐
225 icy settings.
