6 nagios_system_plugin_selinux - Security Enhanced Linux Policy for the
7 nagios_system_plugin processes
8
10 Security-Enhanced Linux secures the nagios_system_plugin processes via
11 flexible mandatory access control.
12
13 The nagios_system_plugin processes execute with the nagios_system_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 nagios_system_plugin_t
20
21
22
24 The nagios_system_plugin_t SELinux type can be entered via the
25 nagios_system_plugin_exec_t file type.
26
27 The default entrypoint paths for the nagios_system_plugin_t domain are
28 the following:
29
30 /usr/lib(64)?/nagios/plugins/check_log, /usr/lib(64)?/nagios/plug‐
31 ins/check_load, /usr/lib(64)?/nagios/plugins/check_mrtg,
32 /usr/lib(64)?/nagios/plugins/check_swap, /usr/lib(64)?/nagios/plug‐
33 ins/check_wave, /usr/lib(64)?/nagios/plugins/check_procs,
34 /usr/lib(64)?/nagios/plugins/check_users, /usr/lib(64)?/nagios/plug‐
35 ins/check_flexlm, /usr/lib(64)?/nagios/plugins/check_nagios,
36 /usr/lib(64)?/nagios/plugins/check_nwstat, /usr/lib(64)?/nagios/plug‐
37 ins/check_overcr, /usr/lib(64)?/nagios/plugins/check_sensors,
38 /usr/lib(64)?/nagios/plugins/check_ifstatus, /usr/lib(64)?/nagios/plug‐
39 ins/check_mrtgtraf, /usr/lib(64)?/nagios/plugins/check_ifoperstatus

42 SELinux defines process types (domains) for each process running on the
43 system
44
45 You can see the context of a process using the -Z option to ps
46
47 Policy governs the access confined processes have to files. SELinux
48 nagios_system_plugin policy is very flexible allowing users to setup
49 their nagios_system_plugin processes in as secure a method as possible.
50
51 The following process types are defined for nagios_system_plugin:
52
53 nagios_system_plugin_t
54
55 Note: semanage permissive -a nagios_system_plugin_t can be used to make
56 the process type nagios_system_plugin_t permissive. SELinux does not
57 deny access to permissive process types, but the AVC (SELinux denials)
58 messages are still generated.
59
60
62 SELinux policy is customizable based on least access required.
63 nagios_system_plugin policy is extremely flexible and has several bool‐
64 eans that allow you to manipulate the policy and run nagios_sys‐
65 tem_plugin with the tightest access possible.
66
67
68
69 If you want to allow all domains to use other domains file descriptors,
70 you must turn on the allow_domain_fd_use boolean. Enabled by default.
71
72 setsebool -P allow_domain_fd_use 1
73
74
75
76 If you want to allow sysadm to debug or ptrace all processes, you must
77 turn on the allow_ptrace boolean. Disabled by default.
78
79 setsebool -P allow_ptrace 1
80
81
82
83 If you want to allow all domains to have the kernel load modules, you
84 must turn on the domain_kernel_load_modules boolean. Disabled by
85 default.
86
87 setsebool -P domain_kernel_load_modules 1
88
89
90
91 If you want to allow all domains to execute in fips_mode, you must turn
92 on the fips_mode boolean. Enabled by default.
93
94 setsebool -P fips_mode 1
95
96
97
98 If you want to enable reading of urandom for all domains, you must turn
99 on the global_ssp boolean. Disabled by default.
100
101 setsebool -P global_ssp 1
102
103
104
106 The SELinux process type nagios_system_plugin_t can manage files
107 labeled with the following file types. The paths listed are the
108 default paths for these file types. Note the processes UID still need
109 to have DAC permissions.
110
111 initrc_tmp_t
112
113
114 mnt_t
115
116 /mnt(/[^/]*)
117 /mnt(/[^/]*)?
118 /rhev(/[^/]*)?
119 /media(/[^/]*)

143
145 SELinux requires files to have an extended attribute to define the file
146 type.
147
148 You can see the context of a file using the -Z option to ls
149
150 Policy governs the access confined processes have to these files.
151 SELinux nagios_system_plugin policy is very flexible allowing users to
152 setup their nagios_system_plugin processes in as secure a method as
153 possible.
154
155 STANDARD FILE CONTEXT
156
157 SELinux defines the file context types for the nagios_system_plugin, if
158 you wanted to store files with these types in a diffent paths, you need
159 to execute the semanage command to sepecify alternate labeling and then
160 use restorecon to put the labels on disk.
161
162 semanage fcontext -a -t nagios_system_plugin_tmp_t '/srv/mynagios_sys‐
163 tem_plugin_content(/.*)?'
164 restorecon -R -v /srv/mynagios_system_plugin_content
165
166 Note: SELinux often uses regular expressions to specify labels that
167 match multiple files.
168
169 The following file types are defined for nagios_system_plugin:
170
171
172
173 nagios_system_plugin_exec_t
174
175 - Set files with the nagios_system_plugin_exec_t type, if you want to
176 transition an executable to the nagios_system_plugin_t domain.
177
178
179 Paths:
180 /usr/lib(64)?/nagios/plugins/check_log, /usr/lib(64)?/nagios/plug‐
181 ins/check_load, /usr/lib(64)?/nagios/plugins/check_mrtg,
182 /usr/lib(64)?/nagios/plugins/check_swap,
183 /usr/lib(64)?/nagios/plugins/check_wave,
184 /usr/lib(64)?/nagios/plugins/check_procs,
185 /usr/lib(64)?/nagios/plugins/check_users,
186 /usr/lib(64)?/nagios/plugins/check_flexlm,
187 /usr/lib(64)?/nagios/plugins/check_nagios,
188 /usr/lib(64)?/nagios/plugins/check_nwstat,
189 /usr/lib(64)?/nagios/plugins/check_overcr,
190 /usr/lib(64)?/nagios/plugins/check_sensors,
191 /usr/lib(64)?/nagios/plugins/check_ifstatus,
192 /usr/lib(64)?/nagios/plugins/check_mrtgtraf,
193 /usr/lib(64)?/nagios/plugins/check_ifoperstatus
194
195
196 nagios_system_plugin_tmp_t
197
198 - Set files with the nagios_system_plugin_tmp_t type, if you want to
199 store nagios system plugin temporary files in the /tmp directories.
200
201
202
203 Note: File context can be temporarily modified with the chcon command.
204 If you want to permanently change the file context you need to use the
205 semanage fcontext command. This will modify the SELinux labeling data‐
206 base. You will need to use restorecon to apply the labels.
207
208
210 semanage fcontext can also be used to manipulate default file context
211 mappings.
212
213 semanage permissive can also be used to manipulate whether or not a
214 process type is permissive.
215
216 semanage module can also be used to enable/disable/install/remove pol‐
217 icy modules.
218
219 semanage boolean can also be used to manipulate the booleans
220
221
222 system-config-selinux is a GUI tool available to customize SELinux pol‐
223 icy settings.
