6 mail_munin_plugin_selinux - Security Enhanced Linux Policy for the
7 mail_munin_plugin processes
8
10 Security-Enhanced Linux secures the mail_munin_plugin processes via
11 flexible mandatory access control.
12
13 The mail_munin_plugin processes execute with the mail_munin_plugin_t
14 SELinux type. You can check if you have these processes running by exe‐
15 cuting the ps command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep mail_munin_plugin_t
20
21
22
24 The mail_munin_plugin_t SELinux type can be entered via the
25 mail_munin_plugin_exec_t file type.
26
27 The default entrypoint paths for the mail_munin_plugin_t domain are the
28 following:
29
30 /usr/share/munin/plugins/qmail.*, /usr/share/munin/plugins/exim_mail.*,
31 /usr/share/munin/plugins/sendmail_.*, /usr/share/munin/plug‐
32 ins/courier_mta_.*, /usr/share/munin/plugins/postfix_mail.*,
33 /usr/share/munin/plugins/mailman, /usr/share/munin/plugins/mailscanner
34
36 SELinux defines process types (domains) for each process running on the
37 system
38
39 You can see the context of a process using the -Z option to ps
40
41 Policy governs the access confined processes have to files. SELinux
42 mail_munin_plugin policy is very flexible allowing users to setup their
43 mail_munin_plugin processes in as secure a method as possible.
44
45 The following process types are defined for mail_munin_plugin:
46
47 mail_munin_plugin_t
48
49 Note: semanage permissive -a mail_munin_plugin_t can be used to make
50 the process type mail_munin_plugin_t permissive. SELinux does not deny
51 access to permissive process types, but the AVC (SELinux denials) mes‐
52 sages are still generated.
53
54
56 SELinux policy is customizable based on least access required.
57 mail_munin_plugin policy is extremely flexible and has several booleans
58 that allow you to manipulate the policy and run mail_munin_plugin with
59 the tightest access possible.
60
61
62
63 If you want to deny any process from ptracing or debugging any other
64 processes, you must turn on the deny_ptrace boolean. Enabled by
65 default.
66
67 setsebool -P deny_ptrace 1
68
69
70
71 If you want to allow any process to mmap any file on system with
72 attribute file_type, you must turn on the domain_can_mmap_files bool‐
73 ean. Enabled by default.
74
75 setsebool -P domain_can_mmap_files 1
76
77
78
79 If you want to allow all domains write to kmsg_device, while kernel is
80 executed with systemd.log_target=kmsg parameter, you must turn on the
81 domain_can_write_kmsg boolean. Disabled by default.
82
83 setsebool -P domain_can_write_kmsg 1
84
85
86
87 If you want to allow all domains to use other domains file descriptors,
88 you must turn on the domain_fd_use boolean. Enabled by default.
89
90 setsebool -P domain_fd_use 1
91
92
93
94 If you want to allow all domains to have the kernel load modules, you
95 must turn on the domain_kernel_load_modules boolean. Disabled by
96 default.
97
98 setsebool -P domain_kernel_load_modules 1
99
100
101
102 If you want to allow all domains to execute in fips_mode, you must turn
103 on the fips_mode boolean. Enabled by default.
104
105 setsebool -P fips_mode 1
106
107
108
109 If you want to enable reading of urandom for all domains, you must turn
110 on the global_ssp boolean. Disabled by default.
111
112 setsebool -P global_ssp 1
113
114
115
116 If you want to allow confined applications to use nscd shared memory,
117 you must turn on the nscd_use_shm boolean. Disabled by default.
118
119 setsebool -P nscd_use_shm 1
120
121
122
124 The SELinux process type mail_munin_plugin_t can manage files labeled
125 with the following file types. The paths listed are the default paths
126 for these file types. Note the processes UID still need to have DAC
127 permissions.
128
129 mail_munin_plugin_tmp_t
130
131
132 munin_plugin_state_t
133
134 /var/lib/munin/plugin-state(/.*)?
135
136 munin_var_lib_t
137
138 /var/lib/munin(/.*)?
139
140
142 SELinux requires files to have an extended attribute to define the file
143 type.
144
145 You can see the context of a file using the -Z option to ls
146
147 Policy governs the access confined processes have to these files.
148 SELinux mail_munin_plugin policy is very flexible allowing users to
149 setup their mail_munin_plugin processes in as secure a method as possi‐
150 ble.
151
152 STANDARD FILE CONTEXT
153
154 SELinux defines the file context types for the mail_munin_plugin, if
155 you wanted to store files with these types in a diffent paths, you need
156 to execute the semanage command to sepecify alternate labeling and then
157 use restorecon to put the labels on disk.
158
159 semanage fcontext -a -t mail_munin_plugin_tmp_t
160 '/srv/mymail_munin_plugin_content(/.*)?'
161 restorecon -R -v /srv/mymail_munin_plugin_content
162
163 Note: SELinux often uses regular expressions to specify labels that
164 match multiple files.
165
166 The following file types are defined for mail_munin_plugin:
167
168
169
170 mail_munin_plugin_exec_t
171
172 - Set files with the mail_munin_plugin_exec_t type, if you want to
173 transition an executable to the mail_munin_plugin_t domain.
174
175
176 Paths:
177 /usr/share/munin/plugins/qmail.*, /usr/share/munin/plug‐
178 ins/exim_mail.*, /usr/share/munin/plugins/sendmail_.*,
179 /usr/share/munin/plugins/courier_mta_.*, /usr/share/munin/plug‐
180 ins/postfix_mail.*, /usr/share/munin/plugins/mailman,
181 /usr/share/munin/plugins/mailscanner
182
183
184 mail_munin_plugin_tmp_t
185
186 - Set files with the mail_munin_plugin_tmp_t type, if you want to store
187 mail munin plugin temporary files in the /tmp directories.
188
189
190
191 Note: File context can be temporarily modified with the chcon command.
192 If you want to permanently change the file context you need to use the
193 semanage fcontext command. This will modify the SELinux labeling data‐
194 base. You will need to use restorecon to apply the labels.
195
196
198 semanage fcontext can also be used to manipulate default file context
199 mappings.
200
201 semanage permissive can also be used to manipulate whether or not a
202 process type is permissive.
203
204 semanage module can also be used to enable/disable/install/remove pol‐
205 icy modules.
206
207 semanage boolean can also be used to manipulate the booleans
208
209
210 system-config-selinux is a GUI tool available to customize SELinux pol‐
211 icy settings.
