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 users to resolve user passwd entries directly from
57 ldap rather then using a sssd server, you must turn on the authlo‐
58 gin_nsswitch_use_ldap boolean. Disabled by default.
59
60 setsebool -P authlogin_nsswitch_use_ldap 1
61
62
63
64 If you want to allow all domains to execute in fips_mode, you must turn
65 on the fips_mode boolean. Enabled by default.
66
67 setsebool -P fips_mode 1
68
69
70
71 If you want to allow confined applications to run with kerberos, you
72 must turn on the kerberos_enabled boolean. Disabled by default.
73
74 setsebool -P kerberos_enabled 1
75
76
77
78 If you want to allow system to run with NIS, you must turn on the
79 nis_enabled boolean. Disabled by default.
80
81 setsebool -P nis_enabled 1
82
83
84
85 If you want to allow confined applications to use nscd shared memory,
86 you must turn on the nscd_use_shm boolean. Disabled by default.
87
88 setsebool -P nscd_use_shm 1
89

91
93 The SELinux process type mrtg_t can manage files labeled with the fol‐
94 lowing file types. The paths listed are the default paths for these
95 file types. Note the processes UID still need to have DAC permissions.

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