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/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.

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.
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

MANAGED FILES

68       The  SELinux  process type courier_tcpd_t can manage files labeled with
69       the following file types.  The paths listed are the default  paths  for
70       these  file  types.  Note the processes UID still need to have DAC per‐
71       missions.
72
73       cluster_conf_t
74
75            /etc/cluster(/.*)?

FILE CONTEXTS

119       SELinux requires files to have an extended attribute to define the file
120       type.
121
122       You can see the context of a file using the -Z option to ls
123
124       Policy  governs  the  access  confined  processes  have to these files.
125       SELinux courier_tcpd policy is very flexible allowing  users  to  setup
126       their courier_tcpd processes in as secure a method as possible.
127
128       The following file types are defined for courier_tcpd:
129
130
131
132       courier_tcpd_exec_t
133
134       -  Set  files with the courier_tcpd_exec_t type, if you want to transi‐
135       tion an executable to the courier_tcpd_t domain.
136
137
138
139       Note: File context can be temporarily modified with the chcon  command.
140       If  you want to permanently change the file context you need to use the
141       semanage fcontext command.  This will modify the SELinux labeling data‐
142       base.  You will need to use restorecon to apply the labels.
143
144

COMMANDS

146       semanage  fcontext  can also be used to manipulate default file context
147       mappings.
148
149       semanage permissive can also be used to manipulate  whether  or  not  a
150       process type is permissive.
151
152       semanage  module can also be used to enable/disable/install/remove pol‐
153       icy modules.
154
155       semanage boolean can also be used to manipulate the booleans
156
157
158       system-config-selinux is a GUI tool available to customize SELinux pol‐
159       icy settings.
