6 prelude_correlator_selinux - Security Enhanced Linux Policy for the
7 prelude_correlator processes
8
10 Security-Enhanced Linux secures the prelude_correlator processes via
11 flexible mandatory access control.
12 The prelude_correlator processes execute with the prelude_correlator_t
14 SELinux type. You can check if you have these processes running by exe‐
15 cuting the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep prelude_correlator_t
20
24 The prelude_correlator_t SELinux type can be entered via the pre‐
25 lude_correlator_exec_t file type.
26 The default entrypoint paths for the prelude_correlator_t domain are
28 the following:
29 /usr/bin/prelude-correlator
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_correlator policy is very flexible allowing users to setup
40 their prelude_correlator processes in as secure a method as possible.
41 The following process types are defined for prelude_correlator:
43 prelude_correlator_t
45 Note: semanage permissive -a prelude_correlator_t can be used to make
47 the process type prelude_correlator_t permissive. SELinux does not deny
48 access to permissive process types, but the AVC (SELinux denials) mes‐
49 sages are still generated.
50
53 SELinux policy is customizable based on least access required. pre‐
54 lude_correlator policy is extremely flexible and has several booleans
55 that allow you to manipulate the policy and run prelude_correlator with
56 the tightest access possible.

120 must turn on the domain_kernel_load_modules boolean. Disabled by
121 default.
122 setsebool -P domain_kernel_load_modules 1
124 If you want to allow all domains to execute in fips_mode, you must turn
128 on the fips_mode boolean. Enabled by default.
129 setsebool -P fips_mode 1
131 If you want to enable reading of urandom for all domains, you must turn
135 on the global_ssp boolean. Disabled by default.
136 setsebool -P global_ssp 1
138 If you want to allow confined applications to use nscd shared memory,
142 you must turn on the nscd_use_shm boolean. Disabled by default.
143 setsebool -P nscd_use_shm 1

149 The SELinux process type prelude_correlator_t can manage files labeled
150 with the following file types. The paths listed are the default paths
151 for these file types. Note the processes UID still need to have DAC
152 permissions.

196 SELinux requires files to have an extended attribute to define the file
197 type.
198 You can see the context of a file using the -Z option to ls
200 Policy governs the access confined processes have to these files.
202 SELinux prelude_correlator policy is very flexible allowing users to
203 setup their prelude_correlator processes in as secure a method as pos‐
204 sible.
205 STANDARD FILE CONTEXT
207 SELinux defines the file context types for the prelude_correlator, if
209 you wanted to store files with these types in a diffent paths, you need
210 to execute the semanage command to sepecify alternate labeling and then
211 use restorecon to put the labels on disk.
212 semanage fcontext -a -t prelude_correlator_config_t '/srv/mypre‐
214 lude_correlator_content(/.*)?'
215 restorecon -R -v /srv/myprelude_correlator_content
216 Note: SELinux often uses regular expressions to specify labels that
218 match multiple files.
219 The following file types are defined for prelude_correlator:
221 prelude_correlator_config_t
225 - Set files with the prelude_correlator_config_t type, if you want to
227 treat the files as prelude correlator configuration data, usually
228 stored under the /etc directory.
229 prelude_correlator_exec_t
233 - Set files with the prelude_correlator_exec_t type, if you want to
235 transition an executable to the prelude_correlator_t domain.
236 Note: File context can be temporarily modified with the chcon command.
240 If you want to permanently change the file context you need to use the
241 semanage fcontext command. This will modify the SELinux labeling data‐
242 base. You will need to use restorecon to apply the labels.
243
246 semanage fcontext can also be used to manipulate default file context
247 mappings.
248 semanage permissive can also be used to manipulate whether or not a
250 process type is permissive.
251 semanage module can also be used to enable/disable/install/remove pol‐
253 icy modules.
254 semanage boolean can also be used to manipulate the booleans
256 system-config-selinux is a GUI tool available to customize SELinux pol‐
259 icy settings.
