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, /usr/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.

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_audisp_t can manage files labeled with
150 the following file types. The paths listed are the default paths for
151 these file types. Note the processes UID still need to have DAC per‐
152 missions.

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_audisp policy is very flexible allowing users to setup
203 their prelude_audisp processes in as secure a method as possible.
204 STANDARD FILE CONTEXT
206 SELinux defines the file context types for the prelude_audisp, if you
208 wanted to store files with these types in a diffent paths, you need to
209 execute the semanage command to sepecify alternate labeling and then
210 use restorecon to put the labels on disk.
211 semanage fcontext -a -t prelude_audisp_var_run_t '/srv/myprelude_aud‐
213 isp_content(/.*)?'
214 restorecon -R -v /srv/myprelude_audisp_content
215 Note: SELinux often uses regular expressions to specify labels that
217 match multiple files.
218 The following file types are defined for prelude_audisp:
220 prelude_audisp_exec_t
224 - Set files with the prelude_audisp_exec_t type, if you want to transi‐
226 tion an executable to the prelude_audisp_t domain.
227 Paths:
230 /sbin/audisp-prelude, /usr/sbin/audisp-prelude
231 prelude_audisp_var_run_t
234 - Set files with the prelude_audisp_var_run_t type, if you want to
236 store the prelude audisp files under the /run or /var/run directory.
237 Note: File context can be temporarily modified with the chcon command.
241 If you want to permanently change the file context you need to use the
242 semanage fcontext command. This will modify the SELinux labeling data‐
243 base. You will need to use restorecon to apply the labels.
244
247 semanage fcontext can also be used to manipulate default file context
248 mappings.
249 semanage permissive can also be used to manipulate whether or not a
251 process type is permissive.
252 semanage module can also be used to enable/disable/install/remove pol‐
254 icy modules.
255 semanage boolean can also be used to manipulate the booleans
257 system-config-selinux is a GUI tool available to customize SELinux pol‐
260 icy settings.
