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 all domains to execute in fips_mode, you must turn
57 on the fips_mode boolean. Enabled by default.
58
59 setsebool -P fips_mode 1
60
61
62
63 If you want to allow nagios/nrpe to call sudo from NRPE utils scripts,
64 you must turn on the nagios_run_sudo boolean. Disabled by default.
65
66 setsebool -P nagios_run_sudo 1
67
68
69
70 If you want to determine whether Nagios, NRPE can access nfs file sys‐
71 tems, you must turn on the nagios_use_nfs boolean. Disabled by default.
72
73 setsebool -P nagios_use_nfs 1
74
75
76
78 The SELinux process type nrpe_t can manage files labeled with the fol‐
79 lowing file types. The paths listed are the default paths for these
80 file types. Note the processes UID still need to have DAC permissions.

144 SELinux requires files to have an extended attribute to define the file
145 type.
146
147 You can see the context of a file using the -Z option to ls
148
149 Policy governs the access confined processes have to these files.
150 SELinux nrpe policy is very flexible allowing users to setup their nrpe
151 processes in as secure a method as possible.
152
153 STANDARD FILE CONTEXT
154
155 SELinux defines the file context types for the nrpe, if you wanted to
156 store files with these types in a diffent paths, you need to execute
157 the semanage command to sepecify alternate labeling and then use
158 restorecon to put the labels on disk.
159
160 semanage fcontext -a -t nrpe_var_run_t '/srv/mynrpe_content(/.*)?'
161 restorecon -R -v /srv/mynrpe_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 nrpe:
167
168
169
170 nrpe_etc_t
171
172 - Set files with the nrpe_etc_t type, if you want to store nrpe files
173 in the /etc directories.
174
175
176
177 nrpe_exec_t
178
179 - Set files with the nrpe_exec_t type, if you want to transition an
180 executable to the nrpe_t domain.
181
182
183 Paths:
184 /usr/bin/nrpe, /usr/sbin/nrpe
185
186
187 nrpe_var_run_t
188
189 - Set files with the nrpe_var_run_t type, if you want to store the nrpe
190 files under the /run or /var/run directory.
191
192
193
194 Note: File context can be temporarily modified with the chcon command.
195 If you want to permanently change the file context you need to use the
196 semanage fcontext command. This will modify the SELinux labeling data‐
197 base. You will need to use restorecon to apply the labels.
198
199
201 semanage fcontext can also be used to manipulate default file context
202 mappings.
203
204 semanage permissive can also be used to manipulate whether or not a
205 process type is permissive.
206
207 semanage module can also be used to enable/disable/install/remove pol‐
208 icy modules.
209
210 semanage boolean can also be used to manipulate the booleans
211
212
213 system-config-selinux is a GUI tool available to customize SELinux pol‐
214 icy settings.
