NAME

6       audisp_selinux  -  Security  Enhanced  Linux Policy for the audisp pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux  secures  the  audisp  processes  via  flexible
11       mandatory access control.
12
13       The  audisp  processes  execute with the audisp_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 audisp_t
20
21
22

ENTRYPOINTS

24       The  audisp_t  SELinux  type  can be entered via the audisp_exec_t file
25       type.
26
27       The default entrypoint paths for the audisp_t domain are the following:
28
29       /sbin/audispd, /usr/sbin/audispd
30

PROCESS TYPES

32       SELinux defines process types (domains) for each process running on the
33       system
34
35       You can see the context of a process using the -Z option to ps
36
37       Policy  governs  the  access confined processes have to files.  SELinux
38       audisp policy is very flexible allowing users  to  setup  their  audisp
39       processes in as secure a method as possible.
40
41       The following process types are defined for audisp:
42
43       audisp_t, audisp_remote_t
44
45       Note:  semanage  permissive -a audisp_t can be used to make the process
46       type audisp_t permissive. SELinux does not deny  access  to  permissive
47       process  types, but the AVC (SELinux denials) messages are still gener‐
48       ated.

BOOLEANS

52       SELinux policy is customizable based on least access required.   audisp
53       policy is extremely flexible and has several booleans that allow you to
54       manipulate the policy and run audisp with the tightest access possible.
55
56
57
58       If you want to allow users to resolve user passwd entries directly from
59       ldap  rather  then  using  a  sssd server, you must turn on the authlo‐
60       gin_nsswitch_use_ldap boolean. Disabled by default.
61
62       setsebool -P authlogin_nsswitch_use_ldap 1

70
71
72
73       If  you  want  to deny any process from ptracing or debugging any other
74       processes, you  must  turn  on  the  deny_ptrace  boolean.  Enabled  by
75       default.
76
77       setsebool -P deny_ptrace 1

79
80
81       If  you  want  to  allow  any  process  to mmap any file on system with
82       attribute file_type, you must turn on the  domain_can_mmap_files  bool‐
83       ean. Enabled by default.
84

86
87
88
89       If  you want to allow all domains write to kmsg_device, while kernel is
90       executed with systemd.log_target=kmsg parameter, you must turn  on  the
91       domain_can_write_kmsg boolean. Disabled by default.

101
102
103
104       If you want to allow all domains to have the kernel load  modules,  you
105       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
106       default.
107
108       setsebool -P domain_kernel_load_modules 1
109

116
117
118
119       If you want to enable reading of urandom for all domains, you must turn
120       on the global_ssp boolean. Disabled by default.
121

143       setsebool -P nscd_use_shm 1
144
145
146

FILE CONTEXTS

148       SELinux requires files to have an extended attribute to define the file
149       type.
150
151       You can see the context of a file using the -Z option to ls
152
153       Policy governs the access  confined  processes  have  to  these  files.
154       SELinux  audisp  policy  is very flexible allowing users to setup their
155       audisp processes in as secure a method as possible.
156
157       STANDARD FILE CONTEXT
158
159       SELinux defines the file context types for the audisp, if you wanted to
160       store  files  with  these types in a diffent paths, you need to execute
161       the semanage command  to  sepecify  alternate  labeling  and  then  use
162       restorecon to put the labels on disk.
163
164       semanage fcontext -a -t audisp_var_run_t '/srv/myaudisp_content(/.*)?'
165       restorecon -R -v /srv/myaudisp_content
166
167       Note:  SELinux  often  uses  regular expressions to specify labels that
168       match multiple files.
169
170       The following file types are defined for audisp:
171
172
173
174       audisp_exec_t
175
176       - Set files with the audisp_exec_t type, if you want to  transition  an
177       executable to the audisp_t domain.
178
179
180       Paths:
181            /sbin/audispd, /usr/sbin/audispd
182
183
184       audisp_remote_exec_t
185
186       -  Set files with the audisp_remote_exec_t type, if you want to transi‐
187       tion an executable to the audisp_remote_t domain.
188
189
190       Paths:
191            /sbin/audisp-remote, /usr/sbin/audisp-remote
192
193
194       audisp_var_run_t
195
196       - Set files with the audisp_var_run_t type, if you want  to  store  the
197       audisp files under the /run or /var/run directory.
198
199
200
201       Note:  File context can be temporarily modified with the chcon command.
202       If you want to permanently change the file context you need to use  the
203       semanage fcontext command.  This will modify the SELinux labeling data‐
204       base.  You will need to use restorecon to apply the labels.
205
206

COMMANDS

208       semanage fcontext can also be used to manipulate default  file  context
209       mappings.
210
211       semanage  permissive  can  also  be used to manipulate whether or not a
212       process type is permissive.
213
214       semanage module can also be used to enable/disable/install/remove  pol‐
215       icy modules.
216
217       semanage boolean can also be used to manipulate the booleans
218
219
220       system-config-selinux is a GUI tool available to customize SELinux pol‐
221       icy settings.
