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 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 For example:
18 ps -eZ | grep nagios_system_plugin_t
20
24 The nagios_system_plugin_t SELinux type can be entered via the
25 nagios_system_plugin_exec_t file type.
26 The default entrypoint paths for the nagios_system_plugin_t domain are
28 the following:
29 /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 You can see the context of a process using the -Z option to ps
46 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 The following process types are defined for nagios_system_plugin:
52 nagios_system_plugin_t
54 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
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 If you want to allow all domains to execute in fips_mode, you must turn
70 on the fips_mode boolean. Enabled by default.
71 setsebool -P fips_mode 1
73
77 SELinux requires files to have an extended attribute to define the file
78 type.
79 You can see the context of a file using the -Z option to ls
81 Policy governs the access confined processes have to these files.
83 SELinux nagios_system_plugin policy is very flexible allowing users to
84 setup their nagios_system_plugin processes in as secure a method as
85 possible.
86 STANDARD FILE CONTEXT
88 SELinux defines the file context types for the nagios_system_plugin, if
90 you wanted to store files with these types in a diffent paths, you need
91 to execute the semanage command to sepecify alternate labeling and then
92 use restorecon to put the labels on disk.
93 semanage fcontext -a -t nagios_system_plugin_tmp_t '/srv/mynagios_sys‐
95 tem_plugin_content(/.*)?'
96 restorecon -R -v /srv/mynagios_system_plugin_content
97 Note: SELinux often uses regular expressions to specify labels that
99 match multiple files.
100 The following file types are defined for nagios_system_plugin:
102 nagios_system_plugin_exec_t
106 - Set files with the nagios_system_plugin_exec_t type, if you want to
108 transition an executable to the nagios_system_plugin_t domain.
109 Paths:
112 /usr/lib(64)?/nagios/plugins/check_log, /usr/lib(64)?/nagios/plug‐
113 ins/check_load, /usr/lib(64)?/nagios/plugins/check_mrtg,
114 /usr/lib(64)?/nagios/plugins/check_swap,
115 /usr/lib(64)?/nagios/plugins/check_wave,
116 /usr/lib(64)?/nagios/plugins/check_procs,
117 /usr/lib(64)?/nagios/plugins/check_users,
118 /usr/lib(64)?/nagios/plugins/check_flexlm,
119 /usr/lib(64)?/nagios/plugins/check_nagios,
120 /usr/lib(64)?/nagios/plugins/check_nwstat,

124 /usr/lib(64)?/nagios/plugins/check_mrtgtraf,
125 /usr/lib(64)?/nagios/plugins/check_ifoperstatus
126 nagios_system_plugin_tmp_t
129 - Set files with the nagios_system_plugin_tmp_t type, if you want to
131 store nagios system plugin temporary files in the /tmp directories.
132 Note: File context can be temporarily modified with the chcon command.
136 If you want to permanently change the file context you need to use the
137 semanage fcontext command. This will modify the SELinux labeling data‐
138 base. You will need to use restorecon to apply the labels.
139
142 semanage fcontext can also be used to manipulate default file context
143 mappings.
144 semanage permissive can also be used to manipulate whether or not a
146 process type is permissive.
147 semanage module can also be used to enable/disable/install/remove pol‐
149 icy modules.
150 semanage boolean can also be used to manipulate the booleans
152 system-config-selinux is a GUI tool available to customize SELinux pol‐
155 icy settings.
