6 auditd_selinux - Security Enhanced Linux Policy for the auditd pro‐
7 cesses
8
10 Security-Enhanced Linux secures the auditd processes via flexible
11 mandatory access control.
12
13 The auditd processes execute with the auditd_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 auditd_t
20
21
22
24 The auditd_t SELinux type can be entered via the auditd_exec_t file
25 type.
26
27 The default entrypoint paths for the auditd_t domain are the following:
28
29 /sbin/auditd, /usr/sbin/auditd
30
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 auditd policy is very flexible allowing users to setup their auditd
39 processes in as secure a method as possible.
40
41 The following process types are defined for auditd:
42
43 auditd_t
44
45 Note: semanage permissive -a auditd_t can be used to make the process
46 type auditd_t permissive. SELinux does not deny access to permissive
47 process types, but the AVC (SELinux denials) messages are still gener‐
48 ated.
49
50
52 SELinux policy is customizable based on least access required. auditd
53 policy is extremely flexible and has several booleans that allow you to
54 manipulate the policy and run auditd with the tightest access possible.
55
56
57
58 If you want to allow all domains to execute in fips_mode, you must turn
59 on the fips_mode boolean. Enabled by default.
60
61 setsebool -P fips_mode 1
62
63
64
66 SELinux defines port types to represent TCP and UDP ports.
67
68 You can see the types associated with a port by using the following
69 command:
70
71 semanage port -l
72
73
74 Policy governs the access confined processes have to these ports.
75 SELinux auditd policy is very flexible allowing users to setup their
76 auditd processes in as secure a method as possible.
77
78 The following port types are defined for auditd:
79
80
81 audit_port_t
82
83
84
85 Default Defined Ports:
86 tcp 60
87
89 The SELinux process type auditd_t can manage files labeled with the
90 following file types. The paths listed are the default paths for these
91 file types. Note the processes UID still need to have DAC permissions.

149 SELinux requires files to have an extended attribute to define the file
150 type.
151
152 You can see the context of a file using the -Z option to ls
153
154 Policy governs the access confined processes have to these files.
155 SELinux auditd policy is very flexible allowing users to setup their
156 auditd processes in as secure a method as possible.
157
158 EQUIVALENCE DIRECTORIES
159
160
161 auditd policy stores data with multiple different file context types
162 under the /var/log/audit directory. If you would like to store the
163 data in a different directory you can use the semanage command to cre‐
164 ate an equivalence mapping. If you wanted to store this data under the
165 /srv directory you would execute the following command:
166
167 semanage fcontext -a -e /var/log/audit /srv/audit
168 restorecon -R -v /srv/audit
169
170 STANDARD FILE CONTEXT
171
172 SELinux defines the file context types for the auditd, if you wanted to
173 store files with these types in a diffent paths, you need to execute
174 the semanage command to sepecify alternate labeling and then use
175 restorecon to put the labels on disk.
176
177 semanage fcontext -a -t auditd_tmp_t '/srv/myauditd_content(/.*)?'
178 restorecon -R -v /srv/myauditd_content
179
180 Note: SELinux often uses regular expressions to specify labels that
181 match multiple files.
182
183 The following file types are defined for auditd:
184
185
186
187 auditd_etc_t
188
189 - Set files with the auditd_etc_t type, if you want to store auditd
190 files in the /etc directories.
191
192
193
194 auditd_exec_t
195
196 - Set files with the auditd_exec_t type, if you want to transition an
197 executable to the auditd_t domain.
198
199
200 Paths:
201 /sbin/auditd, /usr/sbin/auditd
202
203
204 auditd_initrc_exec_t
205
206 - Set files with the auditd_initrc_exec_t type, if you want to transi‐
207 tion an executable to the auditd_initrc_t domain.
208
209
210
211 auditd_log_t
212
213 - Set files with the auditd_log_t type, if you want to treat the data
214 as auditd log data, usually stored under the /var/log directory.
215
216
217 Paths:
218 /var/log/audit(/.*)?, /var/log/audit.log.*
219
220
221 auditd_tmp_t
222
223 - Set files with the auditd_tmp_t type, if you want to store auditd
224 temporary files in the /tmp directories.
225
226
227
228 auditd_unit_file_t
229
230 - Set files with the auditd_unit_file_t type, if you want to treat the
231 files as auditd unit content.
232
233
234
235 auditd_var_run_t
236
237 - Set files with the auditd_var_run_t type, if you want to store the
238 auditd files under the /run or /var/run directory.
239
240
241 Paths:
242 /var/run/auditd.pid, /var/run/auditd_sock, /var/run/audit_events
243
244
245 Note: File context can be temporarily modified with the chcon command.
246 If you want to permanently change the file context you need to use the
247 semanage fcontext command. This will modify the SELinux labeling data‐
248 base. You will need to use restorecon to apply the labels.
249
250
252 semanage fcontext can also be used to manipulate default file context
253 mappings.
254
255 semanage permissive can also be used to manipulate whether or not a
256 process type is permissive.
257
258 semanage module can also be used to enable/disable/install/remove pol‐
259 icy modules.
260
261 semanage port can also be used to manipulate the port definitions
262
263 semanage boolean can also be used to manipulate the booleans
264
265
266 system-config-selinux is a GUI tool available to customize SELinux pol‐
267 icy settings.
