6 prelude_selinux - Security Enhanced Linux Policy for the prelude pro‐
7 cesses
8
10 Security-Enhanced Linux secures the prelude processes via flexible
11 mandatory access control.
12
13 The prelude processes execute with the prelude_t SELinux type. You can
14 check if you have these processes running by executing the ps command
15 with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep prelude_t
20
21
22
24 The prelude_t SELinux type can be entered via the prelude_exec_t file
25 type.
26
27 The default entrypoint paths for the prelude_t domain are the follow‐
28 ing:
29
30 /usr/bin/prelude-manager
31
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 prelude policy is very flexible allowing users to setup their prelude
40 processes in as secure a method as possible.
41
42 The following process types are defined for prelude:
43
44 prelude_t, prelude_audisp_t, prelude_correlator_t, prelude_lml_t
45
46 Note: semanage permissive -a prelude_t can be used to make the process
47 type prelude_t permissive. SELinux does not deny access to permissive
48 process types, but the AVC (SELinux denials) messages are still gener‐
49 ated.
50
51
53 SELinux policy is customizable based on least access required. prelude
54 policy is extremely flexible and has several booleans that allow you to
55 manipulate the policy and run prelude with the tightest access possi‐
56 ble.
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
64
65
66
68 SELinux defines port types to represent TCP and UDP ports.
69
70 You can see the types associated with a port by using the following
71 command:
72
73 semanage port -l
74
75
76 Policy governs the access confined processes have to these ports.
77 SELinux prelude policy is very flexible allowing users to setup their
78 prelude processes in as secure a method as possible.
79
80 The following port types are defined for prelude:
81
82
83 prelude_port_t
84
85
86
87 Default Defined Ports:
88 tcp 4690
89 udp 4690
90
92 The SELinux process type prelude_t can manage files labeled with the
93 following file types. The paths listed are the default paths for these
94 file types. Note the processes UID still need to have DAC permissions.

161 SELinux requires files to have an extended attribute to define the file
162 type.
163
164 You can see the context of a file using the -Z option to ls
165
166 Policy governs the access confined processes have to these files.
167 SELinux prelude policy is very flexible allowing users to setup their
168 prelude processes in as secure a method as possible.
169
170 EQUIVALENCE DIRECTORIES
171
172
173 prelude policy stores data with multiple different file context types
174 under the /var/spool/prelude directory. If you would like to store the
175 data in a different directory you can use the semanage command to cre‐
176 ate an equivalence mapping. If you wanted to store this data under the
177 /srv directory you would execute the following command:
178
179 semanage fcontext -a -e /var/spool/prelude /srv/prelude
180 restorecon -R -v /srv/prelude
181
182 STANDARD FILE CONTEXT
183
184 SELinux defines the file context types for the prelude, if you wanted
185 to store files with these types in a diffent paths, you need to execute
186 the semanage command to specify alternate labeling and then use re‐
187 storecon to put the labels on disk.
188
189 semanage fcontext -a -t prelude_lml_var_run_t '/srv/myprelude_con‐
190 tent(/.*)?'
191 restorecon -R -v /srv/myprelude_content
192
193 Note: SELinux often uses regular expressions to specify labels that
194 match multiple files.
195
196 The following file types are defined for prelude:
197

299
300
301
302 Note: File context can be temporarily modified with the chcon command.
303 If you want to permanently change the file context you need to use the
304 semanage fcontext command. This will modify the SELinux labeling data‐
305 base. You will need to use restorecon to apply the labels.
306
307
309 semanage fcontext can also be used to manipulate default file context
310 mappings.
311
312 semanage permissive can also be used to manipulate whether or not a
313 process type is permissive.
314
315 semanage module can also be used to enable/disable/install/remove pol‐
316 icy modules.
317
318 semanage port can also be used to manipulate the port definitions
319
320 semanage boolean can also be used to manipulate the booleans
321
322
323 system-config-selinux is a GUI tool available to customize SELinux pol‐
324 icy settings.
