NAME

6       nagios_eventhandler_plugin_selinux - Security Enhanced Linux Policy for
7       the nagios_eventhandler_plugin processes
8

DESCRIPTION

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

ENTRYPOINTS

24       The  nagios_eventhandler_plugin_t  SELinux  type can be entered via the
25       nagios_eventhandler_plugin_exec_t file type.
26
27       The  default  entrypoint  paths  for  the  nagios_eventhandler_plugin_t
28       domain are the following:
29
30       /usr/lib/nagios/plugins/eventhandlers(/.*),       /usr/lib/icinga/plug‐
31       ins/eventhandlers(/.*)
32

PROCESS TYPES

34       SELinux defines process types (domains) for each process running on the
35       system
36
37       You can see the context of a process using the -Z option to ps
38
39       Policy  governs  the  access confined processes have to files.  SELinux
40       nagios_eventhandler_plugin policy is very flexible  allowing  users  to
41       setup  their nagios_eventhandler_plugin processes in as secure a method
42       as possible.
43
44       The following process types are defined for nagios_eventhandler_plugin:
45
46       nagios_eventhandler_plugin_t
47
48       Note: semanage permissive -a nagios_eventhandler_plugin_t can  be  used
49       to  make  the  process  type  nagios_eventhandler_plugin_t  permissive.
50       SELinux does not deny access to permissive process types, but  the  AVC
51       (SELinux denials) messages are still generated.
52
53

BOOLEANS

55       SELinux   policy  is  customizable  based  on  least  access  required.
56       nagios_eventhandler_plugin policy is extremely flexible and has several
57       booleans  that  allow you to manipulate the policy and run nagios_even‐
58       thandler_plugin with the tightest access possible.
59
60
61
62       If you want to deny user domains applications to map a memory region as
63       both  executable  and  writable,  this  is dangerous and the executable
64       should be reported in bugzilla, you must turn on the deny_execmem bool‐
65       ean. Enabled by default.
66
67       setsebool -P deny_execmem 1
68
69
70
71       If  you  want  to deny any process from ptracing or debugging any other
72       processes, you  must  turn  on  the  deny_ptrace  boolean.  Enabled  by
73       default.
74
75       setsebool -P deny_ptrace 1
76
77
78
79       If  you  want  to  allow  any  process  to mmap any file on system with
80       attribute file_type, you must turn on the  domain_can_mmap_files  bool‐
81       ean. Enabled by default.
82
83       setsebool -P domain_can_mmap_files 1
84
85
86
87       If  you want to allow all domains write to kmsg_device, while kernel is
88       executed with systemd.log_target=kmsg parameter, you must turn  on  the
89       domain_can_write_kmsg boolean. Disabled by default.
90
91       setsebool -P domain_can_write_kmsg 1
92
93
94
95       If you want to allow all domains to use other domains file descriptors,
96       you must turn on the domain_fd_use boolean. Enabled by default.
97
98       setsebool -P domain_fd_use 1
99
100
101
102       If you want to allow all domains to have the kernel load  modules,  you
103       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
104       default.
105
106       setsebool -P domain_kernel_load_modules 1
107
108
109
110       If you want to allow all domains to execute in fips_mode, you must turn
111       on the fips_mode boolean. Enabled by default.
112
113       setsebool -P fips_mode 1
114
115
116
117       If you want to enable reading of urandom for all domains, you must turn
118       on the global_ssp boolean. Disabled by default.
119
120       setsebool -P global_ssp 1
121
122
123
124       If you want to control the ability to mmap a low area  of  the  address
125       space,  as  configured  by /proc/sys/vm/mmap_min_addr, you must turn on
126       the mmap_low_allowed boolean. Disabled by default.
127
128       setsebool -P mmap_low_allowed 1
129
130
131
132       If you want to disable kernel module loading,  you  must  turn  on  the
133       secure_mode_insmod boolean. Enabled by default.
134
135       setsebool -P secure_mode_insmod 1
136
137
138
139       If  you want to boolean to determine whether the system permits loading
140       policy, setting enforcing mode, and changing boolean values.  Set  this
141       to  true  and  you  have to reboot to set it back, you must turn on the
142       secure_mode_policyload boolean. Enabled by default.
143
144       setsebool -P secure_mode_policyload 1
145
146
147
148       If you want to allow unconfined executables to make their  heap  memory
149       executable.   Doing  this  is  a  really bad idea. Probably indicates a
150       badly coded executable, but could indicate an attack.  This  executable
151       should   be   reported  in  bugzilla,  you  must  turn  on  the  selin‐
152       uxuser_execheap boolean. Disabled by default.
153
154       setsebool -P selinuxuser_execheap 1
155
156
157
158       If you want to  allow  all  unconfined  executables  to  use  libraries
159       requiring  text  relocation  that  are not labeled textrel_shlib_t, you
160       must turn on the selinuxuser_execmod boolean. Enabled by default.
161
162       setsebool -P selinuxuser_execmod 1
163
164
165
166       If you want to allow unconfined executables to make  their  stack  exe‐
167       cutable.   This  should  never, ever be necessary. Probably indicates a
168       badly coded executable, but could indicate an attack.  This  executable
169       should  be reported in bugzilla, you must turn on the selinuxuser_exec‐
170       stack boolean. Enabled by default.
171
172       setsebool -P selinuxuser_execstack 1
173
174
175
176       If you want to support X userspace object manager, you must turn on the
177       xserver_object_manager boolean. Enabled by default.
178
179       setsebool -P xserver_object_manager 1
180
181
182

MANAGED FILES

184       The  SELinux process type nagios_eventhandler_plugin_t can manage files
185       labeled with the following  file  types.   The  paths  listed  are  the
186       default  paths for these file types.  Note the processes UID still need
187       to have DAC permissions.
188
189       file_type
190
191            all files on the system
192
193

FILE CONTEXTS

195       SELinux requires files to have an extended attribute to define the file
196       type.
197
198       You can see the context of a file using the -Z option to ls
199
200       Policy  governs  the  access  confined  processes  have to these files.
201       SELinux nagios_eventhandler_plugin policy  is  very  flexible  allowing
202       users  to setup their nagios_eventhandler_plugin processes in as secure
203       a method as possible.
204
205       STANDARD FILE CONTEXT
206
207       SELinux  defines  the  file  context   types   for   the   nagios_even‐
208       thandler_plugin,  if  you  wanted  to store files with these types in a
209       diffent paths, you need to execute the  semanage  command  to  sepecify
210       alternate labeling and then use restorecon to put the labels on disk.
211
212       semanage  fcontext  -a  -t nagios_eventhandler_plugin_tmp_t '/srv/myna‐
213       gios_eventhandler_plugin_content(/.*)?'
214       restorecon -R -v /srv/mynagios_eventhandler_plugin_content
215
216       Note: SELinux often uses regular expressions  to  specify  labels  that
217       match multiple files.
218
219       The following file types are defined for nagios_eventhandler_plugin:
220
221
222
223       nagios_eventhandler_plugin_exec_t
224
225       -  Set  files  with  the nagios_eventhandler_plugin_exec_t type, if you
226       want to transition an executable  to  the  nagios_eventhandler_plugin_t
227       domain.
228
229
230       Paths:
231            /usr/lib/nagios/plugins/eventhandlers(/.*),  /usr/lib/icinga/plug‐
232            ins/eventhandlers(/.*)
233
234
235       nagios_eventhandler_plugin_tmp_t
236
237       - Set files with the nagios_eventhandler_plugin_tmp_t type, if you want
238       to  store nagios eventhandler plugin temporary files in the /tmp direc‐
239       tories.
240
241
242
243       Note: File context can be temporarily modified with the chcon  command.
244       If  you want to permanently change the file context you need to use the
245       semanage fcontext command.  This will modify the SELinux labeling data‐
246       base.  You will need to use restorecon to apply the labels.
247
248

COMMANDS

250       semanage  fcontext  can also be used to manipulate default file context
251       mappings.
252
253       semanage permissive can also be used to manipulate  whether  or  not  a
254       process type is permissive.
255
256       semanage  module can also be used to enable/disable/install/remove pol‐
257       icy modules.
258
259       semanage boolean can also be used to manipulate the booleans
260
261
262       system-config-selinux is a GUI tool available to customize SELinux pol‐
263       icy settings.
