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/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
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 dontaudit all daemons scheduling requests (setsched,
63 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
64 Enabled by default.
65 setsebool -P daemons_dontaudit_scheduling 1
67 If you want to allow all domains to execute in fips_mode, you must turn
71 on the fips_mode boolean. Enabled by default.
72 setsebool -P fips_mode 1
74
78 The SELinux process type courier_pop_t can manage files labeled with
79 the following file types. The paths listed are the default paths for
80 these file types. Note the processes UID still need to have DAC per‐
81 missions.

129 SELinux requires files to have an extended attribute to define the file
130 type.
131 You can see the context of a file using the -Z option to ls
133 Policy governs the access confined processes have to these files.
135 SELinux courier_pop policy is very flexible allowing users to setup
136 their courier_pop processes in as secure a method as possible.
137 STANDARD FILE CONTEXT
139 SELinux defines the file context types for the courier_pop, if you
141 wanted to store files with these types in a different paths, you need
142 to execute the semanage command to specify alternate labeling and then
143 use restorecon to put the labels on disk.
144 semanage fcontext -a -t courier_pop_exec_t '/srv/courier_pop/con‐
146 tent(/.*)?'
147 restorecon -R -v /srv/mycourier_pop_content
148 Note: SELinux often uses regular expressions to specify labels that
150 match multiple files.
151 The following file types are defined for courier_pop:
153 courier_pop_exec_t
157 - Set files with the courier_pop_exec_t type, if you want to transition
159 an executable to the courier_pop_t domain.
160 Paths:
163 /usr/lib/courier/courier/courierpop.*, /usr/bin/imapd,
164 /usr/sbin/imaplogin, /usr/lib/courier/imapd,
165 /usr/lib/courier/pop3d, /usr/sbin/courier-imapd,
166 /usr/lib/courier/courier/imaplogin
167 Note: File context can be temporarily modified with the chcon command.
170 If you want to permanently change the file context you need to use the
171 semanage fcontext command. This will modify the SELinux labeling data‐
172 base. You will need to use restorecon to apply the labels.
173
176 semanage fcontext can also be used to manipulate default file context
177 mappings.
178 semanage permissive can also be used to manipulate whether or not a
180 process type is permissive.
181 semanage module can also be used to enable/disable/install/remove pol‐
183 icy modules.
184 semanage boolean can also be used to manipulate the booleans
186 system-config-selinux is a GUI tool available to customize SELinux pol‐
189 icy settings.
