NAME

6       courier_tcpd_selinux   -   Security   Enhanced  Linux  Policy  for  the
7       courier_tcpd processes
8

DESCRIPTION

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

ENTRYPOINTS

24       The    courier_tcpd_t   SELinux   type   can   be   entered   via   the
25       courier_tcpd_exec_t file type.
26
27       The default entrypoint paths for the courier_tcpd_t domain are the fol‐
28       lowing:
29
30       /usr/lib(64)?/courier/couriertcpd, /usr/sbin/couriertcpd
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       courier_tcpd  policy  is  very  flexible  allowing users to setup their
40       courier_tcpd processes in as secure a method as possible.
41
42       The following process types are defined for courier_tcpd:
43
44       courier_tcpd_t
45
46       Note: semanage permissive -a courier_tcpd_t can be  used  to  make  the
47       process type courier_tcpd_t permissive. SELinux does not deny access to
48       permissive process types, but the AVC (SELinux  denials)  messages  are
49       still generated.
50
51

BOOLEANS

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

MANAGED FILES

133       The SELinux process type courier_tcpd_t can manage files  labeled  with
134       the  following  file types.  The paths listed are the default paths for
135       these file types.  Note the processes UID still need to have  DAC  per‐
136       missions.

FILE CONTEXTS

210       SELinux requires files to have an extended attribute to define the file
211       type.
212
213       You can see the context of a file using the -Z option to ls
214
215       Policy governs the access  confined  processes  have  to  these  files.
216       SELinux  courier_tcpd  policy  is very flexible allowing users to setup
217       their courier_tcpd processes in as secure a method as possible.
218
219       The following file types are defined for courier_tcpd:
220
221
222
223       courier_tcpd_exec_t
224
225       - Set files with the courier_tcpd_exec_t type, if you want  to  transi‐
226       tion an executable to the courier_tcpd_t domain.
227
228
229       Paths:
230            /usr/lib(64)?/courier/couriertcpd, /usr/sbin/couriertcpd
231
232
233       Note:  File context can be temporarily modified with the chcon command.
234       If you want to permanently change the file context you need to use  the
235       semanage fcontext command.  This will modify the SELinux labeling data‐
236       base.  You will need to use restorecon to apply the labels.
237
238

COMMANDS

240       semanage fcontext can also be used to manipulate default  file  context
241       mappings.
242
243       semanage  permissive  can  also  be used to manipulate whether or not a
244       process type is permissive.
245
246       semanage module can also be used to enable/disable/install/remove  pol‐
247       icy modules.
248
249       semanage boolean can also be used to manipulate the booleans
250
251
252       system-config-selinux is a GUI tool available to customize SELinux pol‐
253       icy settings.
