NAME

6       courier_pop_selinux   -   Security   Enhanced   Linux  Policy  for  the
7       courier_pop processes
8

DESCRIPTION

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

ENTRYPOINTS

24       The    courier_pop_t    SELinux   type   can   be   entered   via   the
25       courier_pop_exec_t file type.
26
27       The default entrypoint paths for the courier_pop_t domain are the  fol‐
28       lowing:
29
30       /usr/lib/courier/courier/courierpop.*,                  /usr/bin/imapd,
31       /usr/sbin/imaplogin,  /usr/lib/courier/imapd,   /usr/lib/courier/pop3d,
32       /usr/sbin/courier-imapd, /usr/lib/courier/courier/imaplogin
33

PROCESS TYPES

35       SELinux defines process types (domains) for each process running on the
36       system
37
38       You can see the context of a process using the -Z option to ps
39
40       Policy governs the access confined processes have  to  files.   SELinux
41       courier_pop  policy  is  very  flexible  allowing  users to setup their
42       courier_pop processes in as secure a method as possible.
43
44       The following process types are defined for courier_pop:
45
46       courier_pop_t
47
48       Note: semanage permissive -a courier_pop_t can  be  used  to  make  the
49       process  type courier_pop_t permissive. SELinux does not deny access to
50       permissive process types, but the AVC (SELinux  denials)  messages  are
51       still generated.
52
53

BOOLEANS

55       SELinux   policy  is  customizable  based  on  least  access  required.
56       courier_pop policy is extremely flexible and has several booleans  that
57       allow  you to manipulate the policy and run courier_pop with the tight‐
58       est access possible.

MANAGED FILES

144       The  SELinux  process  type courier_pop_t can manage files labeled with
145       the following file types.  The paths listed are the default  paths  for
146       these  file  types.  Note the processes UID still need to have DAC per‐
147       missions.

150
151            /etc/cluster(/.*)?

FILE CONTEXTS

194       SELinux requires files to have an extended attribute to define the file
195       type.
196
197       You can see the context of a file using the -Z option to ls
198
199       Policy  governs  the  access  confined  processes  have to these files.
200       SELinux courier_pop policy is very flexible  allowing  users  to  setup
201       their courier_pop processes in as secure a method as possible.
202
203       The following file types are defined for courier_pop:
204
205
206
207       courier_pop_exec_t
208
209       - Set files with the courier_pop_exec_t type, if you want to transition
210       an executable to the courier_pop_t domain.
211
212
213       Paths:
214            /usr/lib/courier/courier/courierpop.*,             /usr/bin/imapd,
215            /usr/sbin/imaplogin,                       /usr/lib/courier/imapd,
216            /usr/lib/courier/pop3d,                   /usr/sbin/courier-imapd,
217            /usr/lib/courier/courier/imaplogin
218
219
220       Note:  File context can be temporarily modified with the chcon command.
221       If you want to permanently change the file context you need to use  the
222       semanage fcontext command.  This will modify the SELinux labeling data‐
223       base.  You will need to use restorecon to apply the labels.
224
225

COMMANDS

227       semanage fcontext can also be used to manipulate default  file  context
228       mappings.
229
230       semanage  permissive  can  also  be used to manipulate whether or not a
231       process type is permissive.
232
233       semanage module can also be used to enable/disable/install/remove  pol‐
234       icy modules.
235
236       semanage boolean can also be used to manipulate the booleans
237
238
239       system-config-selinux is a GUI tool available to customize SELinux pol‐
240       icy settings.
