6 prelude_lml_selinux - Security Enhanced Linux Policy for the pre‐
7 lude_lml processes
8
10 Security-Enhanced Linux secures the prelude_lml processes via flexible
11 mandatory access control.
12 The prelude_lml processes execute with the prelude_lml_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 prelude_lml_t
20
24 The prelude_lml_t SELinux type can be entered via the pre‐
25 lude_lml_exec_t file type.
26 The default entrypoint paths for the prelude_lml_t domain are the fol‐
28 lowing:
29 /usr/bin/prelude-lml
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 Policy governs the access confined processes have to files. SELinux
39 prelude_lml policy is very flexible allowing users to setup their pre‐
40 lude_lml processes in as secure a method as possible.
41 The following process types are defined for prelude_lml:
43 prelude_lml_t
45 Note: semanage permissive -a prelude_lml_t can be used to make the
47 process type prelude_lml_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
53 SELinux policy is customizable based on least access required. pre‐
54 lude_lml policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run prelude_lml with the tight‐
56 est access possible.
57 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 setsebool -P fips_mode 1
64 If you want to allow system to run with NIS, you must turn on the
68 nis_enabled boolean. Disabled by default.
69 setsebool -P nis_enabled 1
71
75 The SELinux process type prelude_lml_t can manage files labeled with
76 the following file types. The paths listed are the default paths for
77 these file types. Note the processes UID still need to have DAC per‐
78 missions.

133 SELinux requires files to have an extended attribute to define the file
134 type.
135 You can see the context of a file using the -Z option to ls
137 Policy governs the access confined processes have to these files.
139 SELinux prelude_lml policy is very flexible allowing users to setup
140 their prelude_lml processes in as secure a method as possible.
141 STANDARD FILE CONTEXT
143 SELinux defines the file context types for the prelude_lml, if you
145 wanted to store files with these types in a diffent paths, you need to
146 execute the semanage command to sepecify alternate labeling and then
147 use restorecon to put the labels on disk.
148 semanage fcontext -a -t prelude_lml_var_run_t '/srv/myprelude_lml_con‐
150 tent(/.*)?'
151 restorecon -R -v /srv/myprelude_lml_content
152 Note: SELinux often uses regular expressions to specify labels that
154 match multiple files.
155 The following file types are defined for prelude_lml:
157 prelude_lml_exec_t
161 - Set files with the prelude_lml_exec_t type, if you want to transition
163 an executable to the prelude_lml_t domain.
164 prelude_lml_tmp_t
168 - Set files with the prelude_lml_tmp_t type, if you want to store pre‐
170 lude lml temporary files in the /tmp directories.
171 prelude_lml_var_run_t
175 - Set files with the prelude_lml_var_run_t type, if you want to store
177 the prelude lml files under the /run or /var/run directory.
178 Note: File context can be temporarily modified with the chcon command.
182 If you want to permanently change the file context you need to use the
183 semanage fcontext command. This will modify the SELinux labeling data‐
184 base. You will need to use restorecon to apply the labels.
185
188 semanage fcontext can also be used to manipulate default file context
189 mappings.
190 semanage permissive can also be used to manipulate whether or not a
192 process type is permissive.
193 semanage module can also be used to enable/disable/install/remove pol‐
195 icy modules.
196 semanage boolean can also be used to manipulate the booleans
198 system-config-selinux is a GUI tool available to customize SELinux pol‐
201 icy settings.
