6 system_munin_plugin_selinux - Security Enhanced Linux Policy for the
7 system_munin_plugin processes
8
10 Security-Enhanced Linux secures the system_munin_plugin processes via
11 flexible mandatory access control.
12
13 The system_munin_plugin processes execute with the system_munin_plug‐
14 in_t SELinux type. You can check if you have these processes running by
15 executing the ps command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep system_munin_plugin_t
20
21
22
24 The system_munin_plugin_t SELinux type can be entered via the sys‐
25 tem_munin_plugin_exec_t file type.
26
27 The default entrypoint paths for the system_munin_plugin_t domain are
28 the following:
29
30 /usr/share/munin/plugins/cpu.*, /usr/share/munin/plugins/if_.*,
31 /usr/share/munin/plugins/nfs.*, /usr/share/munin/plugins/iostat.*,
32 /usr/share/munin/plugins/munin_.*, /usr/share/munin/plugins/acpi,
33 /usr/share/munin/plugins/load, /usr/share/munin/plugins/swap,
34 /usr/share/munin/plugins/forks, /usr/share/munin/plugins/users,
35 /usr/share/munin/plugins/memory, /usr/share/munin/plugins/uptime,
36 /usr/share/munin/plugins/netstat, /usr/share/munin/plugins/threads,
37 /usr/share/munin/plugins/unbound, /usr/share/munin/plugins/irqstats,
38 /usr/share/munin/plugins/proc_pri, /usr/share/munin/plugins/processes,

43 SELinux defines process types (domains) for each process running on the
44 system
45
46 You can see the context of a process using the -Z option to ps
47
48 Policy governs the access confined processes have to files. SELinux
49 system_munin_plugin policy is very flexible allowing users to setup
50 their system_munin_plugin processes in as secure a method as possible.
51
52 The following process types are defined for system_munin_plugin:
53
54 system_munin_plugin_t
55
56 Note: semanage permissive -a system_munin_plugin_t can be used to make
57 the process type system_munin_plugin_t permissive. SELinux does not
58 deny access to permissive process types, but the AVC (SELinux denials)
59 messages are still generated.
60
61
63 SELinux policy is customizable based on least access required. sys‐
64 tem_munin_plugin policy is extremely flexible and has several booleans
65 that allow you to manipulate the policy and run system_munin_plugin
66 with the tightest access possible.
67
68
69
70 If you want to deny any process from ptracing or debugging any other
71 processes, you must turn on the deny_ptrace boolean. Enabled by
72 default.
73
74 setsebool -P deny_ptrace 1
75
76
77
78 If you want to allow any process to mmap any file on system with
79 attribute file_type, you must turn on the domain_can_mmap_files bool‐
80 ean. Enabled by default.
81
82 setsebool -P domain_can_mmap_files 1
83
84
85
86 If you want to allow all domains write to kmsg_device, while kernel is
87 executed with systemd.log_target=kmsg parameter, you must turn on the
88 domain_can_write_kmsg boolean. Disabled by default.
89
90 setsebool -P domain_can_write_kmsg 1
91
92
93
94 If you want to allow all domains to use other domains file descriptors,
95 you must turn on the domain_fd_use boolean. Enabled by default.
96
97 setsebool -P domain_fd_use 1
98
99
100
101 If you want to allow all domains to have the kernel load modules, you
102 must turn on the domain_kernel_load_modules boolean. Disabled by
103 default.
104
105 setsebool -P domain_kernel_load_modules 1
106
107
108
109 If you want to allow all domains to execute in fips_mode, you must turn
110 on the fips_mode boolean. Enabled by default.
111
112 setsebool -P fips_mode 1
113
114
115
116 If you want to enable reading of urandom for all domains, you must turn
117 on the global_ssp boolean. Disabled by default.
118
119 setsebool -P global_ssp 1
120
121
122
123 If you want to allow confined applications to use nscd shared memory,
124 you must turn on the nscd_use_shm boolean. Disabled by default.
125
126 setsebool -P nscd_use_shm 1
127
128
129
131 The SELinux process type system_munin_plugin_t can manage files labeled
132 with the following file types. The paths listed are the default paths
133 for these file types. Note the processes UID still need to have DAC
134 permissions.
135
136 munin_plugin_state_t
137
138 /var/lib/munin/plugin-state(/.*)?
139
140 munin_var_lib_t
141
142 /var/lib/munin(/.*)?
143
144 system_munin_plugin_tmp_t
145
146
147
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 system_munin_plugin policy is very flexible allowing users to
156 setup their system_munin_plugin processes in as secure a method as pos‐
157 sible.
158
159 STANDARD FILE CONTEXT
160
161 SELinux defines the file context types for the system_munin_plugin, if
162 you wanted to store files with these types in a diffent paths, you need
163 to execute the semanage command to sepecify alternate labeling and then
164 use restorecon to put the labels on disk.
165
166 semanage fcontext -a -t system_munin_plugin_tmp_t '/srv/mysys‐
167 tem_munin_plugin_content(/.*)?'
168 restorecon -R -v /srv/mysystem_munin_plugin_content
169
170 Note: SELinux often uses regular expressions to specify labels that
171 match multiple files.
172
173 The following file types are defined for system_munin_plugin:
174
175
176
177 system_munin_plugin_exec_t
178
179 - Set files with the system_munin_plugin_exec_t type, if you want to
180 transition an executable to the system_munin_plugin_t domain.
181
182
183 Paths:
184 /usr/share/munin/plugins/cpu.*, /usr/share/munin/plugins/if_.*,
185 /usr/share/munin/plugins/nfs.*, /usr/share/munin/plugins/iostat.*,
186 /usr/share/munin/plugins/munin_.*, /usr/share/munin/plugins/acpi,
187 /usr/share/munin/plugins/load, /usr/share/munin/plugins/swap,
188 /usr/share/munin/plugins/forks, /usr/share/munin/plugins/users,
189 /usr/share/munin/plugins/memory, /usr/share/munin/plugins/uptime,
190 /usr/share/munin/plugins/netstat, /usr/share/munin/plug‐
191 ins/threads, /usr/share/munin/plugins/unbound,
192 /usr/share/munin/plugins/irqstats, /usr/share/munin/plug‐
193 ins/proc_pri, /usr/share/munin/plugins/processes,
194 /usr/share/munin/plugins/interrupts, /usr/share/munin/plug‐
195 ins/open_files
196
197
198 system_munin_plugin_tmp_t
199
200 - Set files with the system_munin_plugin_tmp_t type, if you want to
201 store system munin plugin temporary files in the /tmp directories.
202
203
204
205 Note: File context can be temporarily modified with the chcon command.
206 If you want to permanently change the file context you need to use the
207 semanage fcontext command. This will modify the SELinux labeling data‐
208 base. You will need to use restorecon to apply the labels.
209
210
212 semanage fcontext can also be used to manipulate default file context
213 mappings.
214
215 semanage permissive can also be used to manipulate whether or not a
216 process type is permissive.
217
218 semanage module can also be used to enable/disable/install/remove pol‐
219 icy modules.
220
221 semanage boolean can also be used to manipulate the booleans
222
223
224 system-config-selinux is a GUI tool available to customize SELinux pol‐
225 icy settings.
