6 munin_selinux - Security Enhanced Linux Policy for the munin processes
7
9 Security-Enhanced Linux secures the munin processes via flexible manda‐
10 tory access control.
11
12 The munin processes execute with the munin_t SELinux type. You can
13 check if you have these processes running by executing the ps command
14 with the -Z qualifier.
15
16 For example:
17
18 ps -eZ | grep munin_t
19
20
21
23 The munin_t SELinux type can be entered via the munin_exec_t file type.
24
25 The default entrypoint paths for the munin_t domain are the following:
26
27 /usr/bin/munin-.*, /usr/sbin/munin-.*, /usr/share/munin/munin-.*
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 munin policy is very flexible allowing users to setup their munin pro‐
37 cesses in as secure a method as possible.
38
39 The following process types are defined for munin:
40
41 munin_t, munin_script_t
42
43 Note: semanage permissive -a munin_t can be used to make the process
44 type munin_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. munin
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run munin 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 SELinux defines port types to represent TCP and UDP ports.
94
95 You can see the types associated with a port by using the following
96 command:
97
98 semanage port -l
99
100
101 Policy governs the access confined processes have to these ports.
102 SELinux munin policy is very flexible allowing users to setup their
103 munin processes in as secure a method as possible.
104
105 The following port types are defined for munin:
106
107
108 munin_port_t
109
110
111
112 Default Defined Ports:
113 tcp 4949
114 udp 4949
115
117 The SELinux process type munin_t can manage files labeled with the fol‐
118 lowing file types. The paths listed are the default paths for these
119 file types. Note the processes UID still need to have DAC permissions.

177 SELinux requires files to have an extended attribute to define the file
178 type.
179
180 You can see the context of a file using the -Z option to ls
181
182 Policy governs the access confined processes have to these files.
183 SELinux munin policy is very flexible allowing users to setup their
184 munin processes in as secure a method as possible.
185
186 EQUIVALENCE DIRECTORIES
187
188
189 munin policy stores data with multiple different file context types
190 under the /var/lib/munin directory. If you would like to store the
191 data in a different directory you can use the semanage command to cre‐
192 ate an equivalence mapping. If you wanted to store this data under the
193 /srv dirctory you would execute the following command:
194
195 semanage fcontext -a -e /var/lib/munin /srv/munin
196 restorecon -R -v /srv/munin
197
198 munin policy stores data with multiple different file context types
199 under the /var/www/html/munin directory. If you would like to store
200 the data in a different directory you can use the semanage command to
201 create an equivalence mapping. If you wanted to store this data under
202 the /srv dirctory you would execute the following command:
203
204 semanage fcontext -a -e /var/www/html/munin /srv/munin
205 restorecon -R -v /srv/munin
206
207 STANDARD FILE CONTEXT
208
209 SELinux defines the file context types for the munin, if you wanted to
210 store files with these types in a diffent paths, you need to execute
211 the semanage command to sepecify alternate labeling and then use
212 restorecon to put the labels on disk.
213
214 semanage fcontext -a -t munin_ra_content_t '/srv/mymunin_content(/.*)?'
215 restorecon -R -v /srv/mymunin_content
216
217 Note: SELinux often uses regular expressions to specify labels that
218 match multiple files.
219
220 The following file types are defined for munin:
221
222

261
262 munin_log_t

326
327
328
329 Note: File context can be temporarily modified with the chcon command.
330 If you want to permanently change the file context you need to use the
331 semanage fcontext command. This will modify the SELinux labeling data‐
332 base. You will need to use restorecon to apply the labels.
333
334
336 semanage fcontext can also be used to manipulate default file context
337 mappings.
338
339 semanage permissive can also be used to manipulate whether or not a
340 process type is permissive.
341
342 semanage module can also be used to enable/disable/install/remove pol‐
343 icy modules.
344
345 semanage port can also be used to manipulate the port definitions
346
347 semanage boolean can also be used to manipulate the booleans
348
349
350 system-config-selinux is a GUI tool available to customize SELinux pol‐
351 icy settings.
