NAME

6       nagios_selinux  -  Security  Enhanced  Linux Policy for the nagios pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux  secures  the  nagios  processes  via  flexible
11       mandatory access control.
12
13       The  nagios  processes  execute with the nagios_t SELinux type. You can
14       check if you have these processes running by executing the  ps  command
15       with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep nagios_t
20
21
22

ENTRYPOINTS

24       The  nagios_t  SELinux  type  can be entered via the nagios_exec_t file
25       type.
26
27       The default entrypoint paths for the nagios_t domain are the following:
28
29       /usr/bin/icinga, /usr/bin/nagios, /usr/sbin/icinga, /usr/sbin/nagios
30

PROCESS TYPES

32       SELinux defines process types (domains) for each process running on the
33       system
34
35       You can see the context of a process using the -Z option to ps
36
37       Policy  governs  the  access confined processes have to files.  SELinux
38       nagios policy is very flexible allowing users  to  setup  their  nagios
39       processes in as secure a method as possible.
40
41       The following process types are defined for nagios:
42
43       nagios_t, nagios_admin_plugin_t, nagios_checkdisk_plugin_t, nagios_mail_plugin_t, nagios_services_plugin_t, nagios_system_plugin_t, nagios_unconfined_plugin_t, nagios_eventhandler_plugin_t, nagios_openshift_plugin_t, nagios_script_t
44
45       Note:  semanage  permissive -a nagios_t can be used to make the process
46       type nagios_t permissive. SELinux does not deny  access  to  permissive
47       process  types, but the AVC (SELinux denials) messages are still gener‐
48       ated.

BOOLEANS

52       SELinux policy is customizable based on least access required.   nagios
53       policy is extremely flexible and has several booleans that allow you to
54       manipulate the policy and run nagios with the tightest access possible.
55
56
57
58       If you want to allow nagios run in  conjunction  with  PNP4Nagios,  you
59       must turn on the nagios_run_pnp4nagios boolean. Disabled by default.
60
61       setsebool -P nagios_run_pnp4nagios 1
62
63
64
65       If  you want to allow nagios/nrpe to call sudo from NRPE utils scripts,
66       you must turn on the nagios_run_sudo boolean. Disabled by default.
67
68       setsebool -P nagios_run_sudo 1
69
70
71
72       If you want to determine whether Nagios, NRPE can access nfs file  sys‐
73       tems, you must turn on the nagios_use_nfs boolean. Disabled by default.
74
75       setsebool -P nagios_use_nfs 1
76
77
78
79       If you want to allow users to resolve user passwd entries directly from
80       ldap rather then using a sssd server, you  must  turn  on  the  authlo‐
81       gin_nsswitch_use_ldap boolean. Disabled by default.
82
83       setsebool -P authlogin_nsswitch_use_ldap 1
84
85
86
87       If you want to allow all domains to execute in fips_mode, you must turn
88       on the fips_mode boolean. Enabled by default.
89
90       setsebool -P fips_mode 1
91
92
93
94       If you want to allow confined applications to run  with  kerberos,  you
95       must turn on the kerberos_enabled boolean. Disabled by default.
96
97       setsebool -P kerberos_enabled 1
98
99
100
101       If  you  want  to  allow  system  to run with NIS, you must turn on the
102       nis_enabled boolean. Disabled by default.
103
104       setsebool -P nis_enabled 1
105
106
107
108       If you want to allow confined applications to use nscd  shared  memory,
109       you must turn on the nscd_use_shm boolean. Disabled by default.
110
111       setsebool -P nscd_use_shm 1
112
113
114

MANAGED FILES

116       The  SELinux  process  type  nagios_t can manage files labeled with the
117       following file types.  The paths listed are the default paths for these
118       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

208       SELinux requires files to have an extended attribute to define the file
209       type.
210
211       You can see the context of a file using the -Z option to ls
212
213       Policy governs the access  confined  processes  have  to  these  files.
214       SELinux  nagios  policy  is very flexible allowing users to setup their
215       nagios processes in as secure a method as possible.
216
217       STANDARD FILE CONTEXT
218
219       SELinux defines the file context types for the nagios, if you wanted to
220       store  files  with  these types in a diffent paths, you need to execute
221       the semanage command  to  sepecify  alternate  labeling  and  then  use
222       restorecon to put the labels on disk.
223
224       semanage   fcontext   -a   -t  nagios_ra_content_t  '/srv/mynagios_con‐
225       tent(/.*)?'
226       restorecon -R -v /srv/mynagios_content
227
228       Note: SELinux often uses regular expressions  to  specify  labels  that
229       match multiple files.
230
231       The following file types are defined for nagios:
