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 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 For example:
17 ps -eZ | grep nrpe_t
19
23 The nrpe_t SELinux type can be entered via the nrpe_exec_t file type.
24 The default entrypoint paths for the nrpe_t domain are the following:
26 /usr/bin/nrpe, /usr/sbin/nrpe
28
30 SELinux defines process types (domains) for each process running on the
31 system
32 You can see the context of a process using the -Z option to ps
34 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 The following process types are defined for nrpe:
40 nrpe_t
42 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
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 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 setsebool -P fips_mode 1
60 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 setsebool -P nagios_run_sudo 1
67 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 setsebool -P nagios_use_nfs 1
74
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.

159 SELinux requires files to have an extended attribute to define the file
160 type.
161 You can see the context of a file using the -Z option to ls
163 Policy governs the access confined processes have to these files.
165 SELinux nrpe policy is very flexible allowing users to setup their nrpe
166 processes in as secure a method as possible.
167 STANDARD FILE CONTEXT
169 SELinux defines the file context types for the nrpe, if you wanted to
171 store files with these types in a diffent paths, you need to execute
172 the semanage command to sepecify alternate labeling and then use re‐
173 storecon to put the labels on disk.
174 semanage fcontext -a -t nrpe_var_run_t '/srv/mynrpe_content(/.*)?'
176 restorecon -R -v /srv/mynrpe_content
177 Note: SELinux often uses regular expressions to specify labels that
179 match multiple files.
180 The following file types are defined for nrpe:
182 nrpe_etc_t
186 - Set files with the nrpe_etc_t type, if you want to store nrpe files
188 in the /etc directories.
189 nrpe_exec_t
193 - Set files with the nrpe_exec_t type, if you want to transition an ex‐
195 ecutable to the nrpe_t domain.
196 Paths:
199 /usr/bin/nrpe, /usr/sbin/nrpe
200 nrpe_var_run_t
203 - Set files with the nrpe_var_run_t type, if you want to store the nrpe
205 files under the /run or /var/run directory.
206 Note: File context can be temporarily modified with the chcon command.
210 If you want to permanently change the file context you need to use the
211 semanage fcontext command. This will modify the SELinux labeling data‐
212 base. You will need to use restorecon to apply the labels.
213
216 semanage fcontext can also be used to manipulate default file context
217 mappings.
218 semanage permissive can also be used to manipulate whether or not a
220 process type is permissive.
221 semanage module can also be used to enable/disable/install/remove pol‐
223 icy modules.
224 semanage boolean can also be used to manipulate the booleans
226 system-config-selinux is a GUI tool available to customize SELinux pol‐
229 icy settings.
