6 courier_pop_selinux - Security Enhanced Linux Policy for the
7 courier_pop processes
8
10 Security-Enhanced Linux secures the courier_pop processes via flexible
11 mandatory access control.
12 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 For example:
18 ps -eZ | grep courier_pop_t
20
24 The courier_pop_t SELinux type can be entered via the
25 courier_pop_exec_t file type.
26 The default entrypoint paths for the courier_pop_t domain are the fol‐
28 lowing:
29 /usr/lib(64)?/courier/imapd, /usr/lib(64)?/courier/pop3d,
31 /usr/lib(64)?/courier/courier/imaplogin,
32 /usr/lib(64)?/courier/courier/courierpop.*, /usr/bin/imapd
33
35 SELinux defines process types (domains) for each process running on the
36 system
37 You can see the context of a process using the -Z option to ps
39 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 The following process types are defined for courier_pop:
45 courier_pop_t
47 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
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.
59 If you want to allow all daemons to write corefiles to /, you must turn
63 on the allow_daemons_dump_core boolean. Disabled by default.

77 you must turn on the allow_daemons_use_tty boolean. Disabled by
78 default.
79 setsebool -P allow_daemons_use_tty 1
81 If you want to allow all domains to use other domains file descriptors,
85 you must turn on the allow_domain_fd_use boolean. Enabled by default.
86 setsebool -P allow_domain_fd_use 1
88 If you want to allow sysadm to debug or ptrace all processes, you must
92 turn on the allow_ptrace boolean. Disabled by default.
93 setsebool -P allow_ptrace 1
95 If you want to enable cluster mode for daemons, you must turn on the
99 daemons_enable_cluster_mode boolean. Disabled by default.
100 setsebool -P daemons_enable_cluster_mode 1
102 If you want to allow all domains to have the kernel load modules, you
106 must turn on the domain_kernel_load_modules boolean. Disabled by
107 default.
108 setsebool -P domain_kernel_load_modules 1
110 If you want to allow all domains to execute in fips_mode, you must turn
114 on the fips_mode boolean. Enabled by default.
115 setsebool -P fips_mode 1
117 If you want to enable reading of urandom for all domains, you must turn
121 on the global_ssp boolean. Disabled by default.
122 setsebool -P global_ssp 1
124 If you want to enable support for upstart as the init program, you must
128 turn on the init_upstart boolean. Enabled by default.
129 setsebool -P init_upstart 1

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

208 SELinux requires files to have an extended attribute to define the file
209 type.
210 You can see the context of a file using the -Z option to ls
212 Policy governs the access confined processes have to these files.
214 SELinux courier_pop policy is very flexible allowing users to setup
215 their courier_pop processes in as secure a method as possible.
216 The following file types are defined for courier_pop:
218 courier_pop_exec_t
222 - Set files with the courier_pop_exec_t type, if you want to transition
224 an executable to the courier_pop_t domain.
225 Paths:
228 /usr/lib(64)?/courier/imapd, /usr/lib(64)?/courier/pop3d,
229 /usr/lib(64)?/courier/courier/imaplogin,
230 /usr/lib(64)?/courier/courier/courierpop.*, /usr/bin/imapd
231 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
240 semanage fcontext can also be used to manipulate default file context
241 mappings.
242 semanage permissive can also be used to manipulate whether or not a
244 process type is permissive.
245 semanage module can also be used to enable/disable/install/remove pol‐
247 icy modules.
248 semanage boolean can also be used to manipulate the booleans
250 system-config-selinux is a GUI tool available to customize SELinux pol‐
253 icy settings.
