NAME

6       postgrey_selinux - Security Enhanced Linux Policy for the postgrey pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux secures the  postgrey  processes  via  flexible
11       mandatory access control.
12
13       The  postgrey  processes  execute with the postgrey_t SELinux type. You
14       can check if you have these processes running by executing the ps  com‐
15       mand with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep postgrey_t
20
21
22

ENTRYPOINTS

24       The postgrey_t SELinux type can be entered via the postgrey_exec_t file
25       type.
26
27       The default entrypoint paths for the postgrey_t domain are the  follow‐
28       ing:
29
30       /usr/sbin/postgrey
31

PROCESS TYPES

33       SELinux defines process types (domains) for each process running on the
34       system
35
36       You can see the context of a process using the -Z option to ps
37
38       Policy governs the access confined processes have  to  files.   SELinux
39       postgrey policy is very flexible allowing users to setup their postgrey
40       processes in as secure a method as possible.
41
42       The following process types are defined for postgrey:
43
44       postgrey_t
45
46       Note: semanage permissive -a postgrey_t can be used to make the process
47       type  postgrey_t permissive. SELinux does not deny access to permissive
48       process types, but the AVC (SELinux denials) messages are still  gener‐
49       ated.
50
51

BOOLEANS

53       SELinux  policy  is customizable based on least access required.  post‐
54       grey policy is extremely flexible and has several booleans  that  allow
55       you  to manipulate the policy and run postgrey with the tightest access
56       possible.
57
58
59
60       If you want to allow all domains to execute in fips_mode, you must turn
61       on the fips_mode boolean. Enabled by default.
62
63       setsebool -P fips_mode 1
64
65
66

PORT TYPES

68       SELinux defines port types to represent TCP and UDP ports.
69
70       You  can  see  the  types associated with a port by using the following
71       command:
72
73       semanage port -l
74
75
76       Policy governs the access  confined  processes  have  to  these  ports.
77       SELinux  postgrey policy is very flexible allowing users to setup their
78       postgrey processes in as secure a method as possible.
79
80       The following port types are defined for postgrey:
81
82
83       postgrey_port_t
84
85
86
87       Default Defined Ports:
88                 tcp 60000
89

MANAGED FILES

91       The SELinux process type postgrey_t can manage files labeled  with  the
92       following file types.  The paths listed are the default paths for these
93       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

163       SELinux requires files to have an extended attribute to define the file
164       type.
165
166       You can see the context of a file using the -Z option to ls
167
168       Policy  governs  the  access  confined  processes  have to these files.
169       SELinux postgrey policy is very flexible allowing users to setup  their
170       postgrey processes in as secure a method as possible.
171
172       EQUIVALENCE DIRECTORIES
173
174
175       postgrey  policy stores data with multiple different file context types
176       under the /var/run/postgrey directory.  If you would like to store  the
177       data  in a different directory you can use the semanage command to cre‐
178       ate an equivalence mapping.  If you wanted to store this data under the
179       /srv directory you would execute the following command:
180
181       semanage fcontext -a -e /var/run/postgrey /srv/postgrey
182       restorecon -R -v /srv/postgrey
183
184       STANDARD FILE CONTEXT
185
186       SELinux  defines the file context types for the postgrey, if you wanted
187       to store files with these types in a diffent paths, you need to execute
188       the  semanage  command  to  specify alternate labeling and then use re‐
189       storecon to put the labels on disk.
190
191       semanage  fcontext  -a  -t   postgrey_var_run_t   '/srv/mypostgrey_con‐
192       tent(/.*)?'
193       restorecon -R -v /srv/mypostgrey_content
194
195       Note:  SELinux  often  uses  regular expressions to specify labels that
196       match multiple files.
197
198       The following file types are defined for postgrey:
199
200
201
202       postgrey_etc_t
203
204       - Set files with the postgrey_etc_t type, if you want to store postgrey
205       files in the /etc directories.
206
207
208
209       postgrey_exec_t
210
211       - Set files with the postgrey_exec_t type, if you want to transition an
212       executable to the postgrey_t domain.
213
214
215
216       postgrey_initrc_exec_t
217
218       - Set files with the postgrey_initrc_exec_t type, if you want to  tran‐
219       sition an executable to the postgrey_initrc_t domain.
220
221
222
223       postgrey_spool_t
224
225       -  Set  files  with the postgrey_spool_t type, if you want to store the
226       postgrey files under the /var/spool directory.
227
228
229
230       postgrey_var_lib_t
231
232       - Set files with the postgrey_var_lib_t type, if you want to store  the
233       postgrey files under the /var/lib directory.
234
235
236
237       postgrey_var_run_t
238
239       -  Set files with the postgrey_var_run_t type, if you want to store the
240       postgrey files under the /run or /var/run directory.
241
242
243       Paths:
244            /var/run/postgrey(/.*)?, /var/run/postgrey.pid
245
246
247       Note: File context can be temporarily modified with the chcon  command.
248       If  you want to permanently change the file context you need to use the
249       semanage fcontext command.  This will modify the SELinux labeling data‐
250       base.  You will need to use restorecon to apply the labels.
251
252

COMMANDS

254       semanage  fcontext  can also be used to manipulate default file context
255       mappings.
256
257       semanage permissive can also be used to manipulate  whether  or  not  a
258       process type is permissive.
259
260       semanage  module can also be used to enable/disable/install/remove pol‐
261       icy modules.
262
263       semanage port can also be used to manipulate the port definitions
264
265       semanage boolean can also be used to manipulate the booleans
266
267
268       system-config-selinux is a GUI tool available to customize SELinux pol‐
269       icy settings.
