6 mrtg_selinux - Security Enhanced Linux Policy for the mrtg processes
7
9 Security-Enhanced Linux secures the mrtg processes via flexible manda‐
10 tory access control.
11
12 The mrtg processes execute with the mrtg_t SELinux type. You can check
13 if you have these processes running by executing the ps command with
14 the -Z qualifier.
15
16 For example:
17
18 ps -eZ | grep mrtg_t
19
20
21
23 The mrtg_t SELinux type can be entered via the mrtg_exec_t file type.
24
25 The default entrypoint paths for the mrtg_t domain are the following:
26
27 /usr/bin/mrtg
28
30 SELinux defines process types (domains) for each process running on the
31 system
32
33 You can see the context of a process using the -Z option to ps
34
35 Policy governs the access confined processes have to files. SELinux
36 mrtg policy is very flexible allowing users to setup their mrtg pro‐
37 cesses in as secure a method as possible.
38
39 The following process types are defined for mrtg:
40
41 mrtg_t
42
43 Note: semanage permissive -a mrtg_t can be used to make the process
44 type mrtg_t permissive. SELinux does not deny access to permissive
45 process types, but the AVC (SELinux denials) messages are still gener‐
46 ated.
47
48
50 SELinux policy is customizable based on least access required. mrtg
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run mrtg with the tightest access possible.
53
54
55
56 If you want to allow all domains to execute in fips_mode, you must turn
57 on the fips_mode boolean. Enabled by default.
58
59 setsebool -P fips_mode 1
60
61
62
63 If you want to allow system to run with NIS, you must turn on the
64 nis_enabled boolean. Disabled by default.
65
66 setsebool -P nis_enabled 1
67
68
69
71 The SELinux process type mrtg_t can manage files labeled with the fol‐
72 lowing file types. The paths listed are the default paths for these
73 file types. Note the processes UID still need to have DAC permissions.

131 SELinux requires files to have an extended attribute to define the file
132 type.
133
134 You can see the context of a file using the -Z option to ls
135
136 Policy governs the access confined processes have to these files.
137 SELinux mrtg policy is very flexible allowing users to setup their mrtg
138 processes in as secure a method as possible.
139
140 EQUIVALENCE DIRECTORIES
141
142
143 mrtg policy stores data with multiple different file context types un‐
144 der the /var/lock/mrtg directory. If you would like to store the data
145 in a different directory you can use the semanage command to create an
146 equivalence mapping. If you wanted to store this data under the /srv
147 directory you would execute the following command:
148
149 semanage fcontext -a -e /var/lock/mrtg /srv/mrtg
150 restorecon -R -v /srv/mrtg
151
152 STANDARD FILE CONTEXT
153
154 SELinux defines the file context types for the mrtg, if you wanted to
155 store files with these types in a diffent paths, you need to execute
156 the semanage command to specify alternate labeling and then use re‐
157 storecon to put the labels on disk.
158
159 semanage fcontext -a -t mrtg_var_run_t '/srv/mymrtg_content(/.*)?'
160 restorecon -R -v /srv/mymrtg_content
161
162 Note: SELinux often uses regular expressions to specify labels that
163 match multiple files.
164
165 The following file types are defined for mrtg:
166
167
168
169 mrtg_etc_t
170
171 - Set files with the mrtg_etc_t type, if you want to store mrtg files
172 in the /etc directories.
173
174
175
176 mrtg_exec_t
177
178 - Set files with the mrtg_exec_t type, if you want to transition an ex‐
179 ecutable to the mrtg_t domain.
180
181
182
183 mrtg_initrc_exec_t
184
185 - Set files with the mrtg_initrc_exec_t type, if you want to transition
186 an executable to the mrtg_initrc_t domain.
187
188
189
190 mrtg_lock_t
191
192 - Set files with the mrtg_lock_t type, if you want to treat the files
193 as mrtg lock data, stored under the /var/lock directory
194
195
196 Paths:
197 /var/lock/mrtg(/.*)?, /var/lock/mrtg-rrd(/.*)?, /etc/mrtg/mrtg.ok,
198 /var/lock/subsys/mrtg
199
200
201 mrtg_log_t
202
203 - Set files with the mrtg_log_t type, if you want to treat the data as
204 mrtg log data, usually stored under the /var/log directory.
205
206
207
208 mrtg_tmp_t
209
210 - Set files with the mrtg_tmp_t type, if you want to store mrtg tempo‐
211 rary files in the /tmp directories.
212
213
214
215 mrtg_var_lib_t
216
217 - Set files with the mrtg_var_lib_t type, if you want to store the mrtg
218 files under the /var/lib directory.
219
220
221
222 mrtg_var_run_t
223
224 - Set files with the mrtg_var_run_t type, if you want to store the mrtg
225 files under the /run or /var/run directory.
226
227
228
229 Note: File context can be temporarily modified with the chcon command.
230 If you want to permanently change the file context you need to use the
231 semanage fcontext command. This will modify the SELinux labeling data‐
232 base. You will need to use restorecon to apply the labels.
233
234
236 semanage fcontext can also be used to manipulate default file context
237 mappings.
238
239 semanage permissive can also be used to manipulate whether or not a
240 process type is permissive.
241
242 semanage module can also be used to enable/disable/install/remove pol‐
243 icy modules.
244
245 semanage boolean can also be used to manipulate the booleans
246
247
248 system-config-selinux is a GUI tool available to customize SELinux pol‐
249 icy settings.
