6 nrpe_selinux - Security Enhanced Linux Policy for the nrpe processes
7
9 Security-Enhanced Linux secures the nrpe processes via flexible manda‐
10 tory access control.
11
12 The nrpe processes execute with the nrpe_t SELinux type. You can check
13 if you have these processes running by executing the ps command with
14 the -Z qualifier.
15
16 For example:
17
18 ps -eZ | grep nrpe_t
19
20
21
23 The nrpe_t SELinux type can be entered via the nrpe_exec_t file type.
24
25 The default entrypoint paths for the nrpe_t domain are the following:
26
27 /usr/bin/nrpe, /usr/sbin/nrpe
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 nrpe policy is very flexible allowing users to setup their nrpe pro‐
37 cesses in as secure a method as possible.
38
39 The following process types are defined for nrpe:
40
41 nrpe_t
42
43 Note: semanage permissive -a nrpe_t can be used to make the process
44 type nrpe_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. nrpe
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run nrpe 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. Enabled by default.
73
74 setsebool -P kerberos_enabled 1
75
76
77
78 If you want to allow nagios/nrpe to call sudo from NRPE utils scripts,
79 you must turn on the nagios_run_sudo boolean. Disabled by default.
80
81 setsebool -P nagios_run_sudo 1
82
83
84
85 If you want to determine whether Nagios, NRPE can access nfs file sys‐
86 tems, you must turn on the nagios_use_nfs boolean. Disabled by default.
87
88 setsebool -P nagios_use_nfs 1
89
90
91
92 If you want to allow system to run with NIS, you must turn on the
93 nis_enabled boolean. Disabled by default.
94
95 setsebool -P nis_enabled 1
96
97
98
99 If you want to allow confined applications to use nscd shared memory,
100 you must turn on the nscd_use_shm boolean. Enabled by default.
101
102 setsebool -P nscd_use_shm 1
103
104
105
107 The SELinux process type nrpe_t can manage files labeled with the fol‐
108 lowing file types. The paths listed are the default paths for these
109 file types. Note the processes UID still need to have DAC permissions.

173 SELinux requires files to have an extended attribute to define the file
174 type.
175
176 You can see the context of a file using the -Z option to ls
177
178 Policy governs the access confined processes have to these files.
179 SELinux nrpe policy is very flexible allowing users to setup their nrpe
180 processes in as secure a method as possible.
181
182 STANDARD FILE CONTEXT
183
184 SELinux defines the file context types for the nrpe, if you wanted to
185 store files with these types in a diffent paths, you need to execute
186 the semanage command to sepecify alternate labeling and then use
187 restorecon to put the labels on disk.
188
189 semanage fcontext -a -t nrpe_var_run_t '/srv/mynrpe_content(/.*)?'
190 restorecon -R -v /srv/mynrpe_content
191
192 Note: SELinux often uses regular expressions to specify labels that
193 match multiple files.
194
195 The following file types are defined for nrpe:
196
197
198
199 nrpe_etc_t
200
201 - Set files with the nrpe_etc_t type, if you want to store nrpe files
202 in the /etc directories.
203
204
205
206 nrpe_exec_t
207
208 - Set files with the nrpe_exec_t type, if you want to transition an
209 executable to the nrpe_t domain.
210
211
212 Paths:
213 /usr/bin/nrpe, /usr/sbin/nrpe
214
215
216 nrpe_var_run_t
217
218 - Set files with the nrpe_var_run_t type, if you want to store the nrpe
219 files under the /run or /var/run directory.
220
221
222
223 Note: File context can be temporarily modified with the chcon command.
224 If you want to permanently change the file context you need to use the
225 semanage fcontext command. This will modify the SELinux labeling data‐
226 base. You will need to use restorecon to apply the labels.
227
228
230 semanage fcontext can also be used to manipulate default file context
231 mappings.
232
233 semanage permissive can also be used to manipulate whether or not a
234 process type is permissive.
235
236 semanage module can also be used to enable/disable/install/remove pol‐
237 icy modules.
238
239 semanage boolean can also be used to manipulate the booleans
240
241
242 system-config-selinux is a GUI tool available to customize SELinux pol‐
243 icy settings.
