6 prelude_audisp_selinux - Security Enhanced Linux Policy for the pre‐
7 lude_audisp processes
8
10 Security-Enhanced Linux secures the prelude_audisp processes via flexi‐
11 ble mandatory access control.
12 The prelude_audisp processes execute with the prelude_audisp_t SELinux
14 type. You can check if you have these processes running by executing
15 the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep prelude_audisp_t
20
24 The prelude_audisp_t SELinux type can be entered via the prelude_aud‐
25 isp_exec_t file type.
26 The default entrypoint paths for the prelude_audisp_t domain are the
28 following:
29 /sbin/audisp-prelude
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_audisp policy is very flexible allowing users to setup their
40 prelude_audisp processes in as secure a method as possible.
41 The following process types are defined for prelude_audisp:
43 prelude_audisp_t
45 Note: semanage permissive -a prelude_audisp_t can be used to make the
47 process type prelude_audisp_t permissive. SELinux does not deny access
48 to 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_audisp policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run prelude_audisp with the
56 tightest access possible.
57 If you want to allow all daemons to write corefiles to /, you must turn
61 on the allow_daemons_dump_core boolean. Disabled by default.

83 you must turn on the allow_domain_fd_use boolean. Enabled by default.
84 setsebool -P allow_domain_fd_use 1

90 turn on the allow_ptrace boolean. Disabled by default.
91 setsebool -P allow_ptrace 1
93 If you want to enable cluster mode for daemons, you must turn on the
97 daemons_enable_cluster_mode boolean. Disabled by default.
98 setsebool -P daemons_enable_cluster_mode 1
100 If you want to allow all domains to have the kernel load modules, you
104 must turn on the domain_kernel_load_modules boolean. Disabled by
105 default.
106 setsebool -P domain_kernel_load_modules 1
108 If you want to allow all domains to execute in fips_mode, you must turn
112 on the fips_mode boolean. Enabled by default.
113 setsebool -P fips_mode 1
115 If you want to enable reading of urandom for all domains, you must turn
119 on the global_ssp boolean. Disabled by default.
120 setsebool -P global_ssp 1
122 If you want to enable support for upstart as the init program, you must
126 turn on the init_upstart boolean. Enabled by default.
127 setsebool -P init_upstart 1

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

202 SELinux requires files to have an extended attribute to define the file
203 type.
204 You can see the context of a file using the -Z option to ls
206 Policy governs the access confined processes have to these files.
208 SELinux prelude_audisp policy is very flexible allowing users to setup
209 their prelude_audisp processes in as secure a method as possible.
210 STANDARD FILE CONTEXT
212 SELinux defines the file context types for the prelude_audisp, if you
214 wanted to store files with these types in a diffent paths, you need to
215 execute the semanage command to sepecify alternate labeling and then
216 use restorecon to put the labels on disk.
217 semanage fcontext -a -t prelude_audisp_var_run_t '/srv/myprelude_aud‐
219 isp_content(/.*)?'
220 restorecon -R -v /srv/myprelude_audisp_content
221 Note: SELinux often uses regular expressions to specify labels that
223 match multiple files.
224 The following file types are defined for prelude_audisp:
226 prelude_audisp_exec_t
230 - Set files with the prelude_audisp_exec_t type, if you want to transi‐
232 tion an executable to the prelude_audisp_t domain.
233 prelude_audisp_var_run_t
237 - Set files with the prelude_audisp_var_run_t type, if you want to
239 store the prelude audisp files under the /run or /var/run directory.
240 Note: File context can be temporarily modified with the chcon command.
244 If you want to permanently change the file context you need to use the
245 semanage fcontext command. This will modify the SELinux labeling data‐
246 base. You will need to use restorecon to apply the labels.
247
250 semanage fcontext can also be used to manipulate default file context
251 mappings.
252 semanage permissive can also be used to manipulate whether or not a
254 process type is permissive.
255 semanage module can also be used to enable/disable/install/remove pol‐
257 icy modules.
258 semanage boolean can also be used to manipulate the booleans
260 system-config-selinux is a GUI tool available to customize SELinux pol‐
263 icy settings.
