NAME

6       nagios_unconfined_plugin_selinux  -  Security Enhanced Linux Policy for
7       the nagios_unconfined_plugin processes
8

DESCRIPTION

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

ENTRYPOINTS

24       The  nagios_unconfined_plugin_t  SELinux  type  can  be entered via the
25       nagios_unconfined_plugin_exec_t file type.
26
27       The default entrypoint paths for the nagios_unconfined_plugin_t  domain
28       are the following:
29
30       /usr/lib/nagios/plugins/.*
31

PROCESS TYPES

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

BOOLEANS

54       SELinux  policy  is  customizable  based  on  least  access   required.
55       nagios_unconfined_plugin  policy  is extremely flexible and has several
56       booleans that allow you to manipulate the policy and run  nagios_uncon‐
57       fined_plugin with the tightest access possible.
58
59
60
61       If you want to deny user domains applications to map a memory region as
62       both executable and writable, this  is  dangerous  and  the  executable
63       should be reported in bugzilla, you must turn on the deny_execmem bool‐
64       ean. Enabled by default.
65
66       setsebool -P deny_execmem 1
67
68
69
70       If you want to deny any process from ptracing or  debugging  any  other
71       processes,  you  must  turn  on  the  deny_ptrace  boolean.  Enabled by
72       default.
73
74       setsebool -P deny_ptrace 1
75
76
77
78       If you want to allow any process  to  mmap  any  file  on  system  with
79       attribute  file_type,  you must turn on the domain_can_mmap_files bool‐
80       ean. Enabled by default.
81
82       setsebool -P domain_can_mmap_files 1
83
84
85
86       If you want to allow all domains write to kmsg_device, while kernel  is
87       executed  with  systemd.log_target=kmsg parameter, you must turn on the
88       domain_can_write_kmsg boolean. Disabled by default.
89
90       setsebool -P domain_can_write_kmsg 1
91
92
93
94       If you want to allow all domains to use other domains file descriptors,
95       you must turn on the domain_fd_use boolean. Enabled by default.
96
97       setsebool -P domain_fd_use 1
98
99
100
101       If  you  want to allow all domains to have the kernel load modules, you
102       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
103       default.
104
105       setsebool -P domain_kernel_load_modules 1
106
107
108
109       If you want to allow all domains to execute in fips_mode, you must turn
110       on the fips_mode boolean. Enabled by default.
111
112       setsebool -P fips_mode 1
113
114
115
116       If you want to enable reading of urandom for all domains, you must turn
117       on the global_ssp boolean. Disabled by default.
118
119       setsebool -P global_ssp 1
120
121
122
123       If  you want to allow syslogd the ability to call nagios plugins. It is
124       turned on by omprog rsyslog plugin, you must turn on  the  logging_sys‐
125       logd_run_nagios_plugins boolean. Disabled by default.
126
127       setsebool -P logging_syslogd_run_nagios_plugins 1
128
129
130
131       If  you  want  to control the ability to mmap a low area of the address
132       space, as configured by /proc/sys/vm/mmap_min_addr, you  must  turn  on
133       the mmap_low_allowed boolean. Disabled by default.
134
135       setsebool -P mmap_low_allowed 1
136
137
138
139       If  you  want  to  disable  kernel module loading, you must turn on the
140       secure_mode_insmod boolean. Enabled by default.
141
142       setsebool -P secure_mode_insmod 1
143
144
145
146       If you want to boolean to determine whether the system permits  loading
147       policy,  setting enforcing mode, and changing boolean values.  Set this
148       to true and you have to reboot to set it back, you  must  turn  on  the
149       secure_mode_policyload boolean. Enabled by default.
150
151       setsebool -P secure_mode_policyload 1
152
153
154
155       If  you  want to allow unconfined executables to make their heap memory
156       executable.  Doing this is a really  bad  idea.  Probably  indicates  a
157       badly  coded  executable, but could indicate an attack. This executable
158       should  be  reported  in  bugzilla,  you  must  turn  on   the   selin‐
159       uxuser_execheap boolean. Disabled by default.
160
161       setsebool -P selinuxuser_execheap 1
162
163
164
165       If  you  want  to  allow  all  unconfined  executables to use libraries
166       requiring text relocation that are  not  labeled  textrel_shlib_t,  you
167       must turn on the selinuxuser_execmod boolean. Enabled by default.
168
169       setsebool -P selinuxuser_execmod 1
170
171
172
173       If  you  want  to allow unconfined executables to make their stack exe‐
174       cutable.  This should never, ever be necessary.  Probably  indicates  a
175       badly  coded  executable, but could indicate an attack. This executable
176       should be reported in bugzilla, you must turn on the  selinuxuser_exec‐
177       stack boolean. Enabled by default.
178
179       setsebool -P selinuxuser_execstack 1
180
181
182
183       If you want to support X userspace object manager, you must turn on the
184       xserver_object_manager boolean. Enabled by default.
185
186       setsebool -P xserver_object_manager 1

MANAGED FILES

191       The SELinux process type nagios_unconfined_plugin_t  can  manage  files
192       labeled  with  the  following  file  types.   The  paths listed are the
193       default paths for these file types.  Note the processes UID still  need
194       to have DAC permissions.
195
196       file_type
197
198            all files on the system
199
200

FILE CONTEXTS

202       SELinux requires files to have an extended attribute to define the file
203       type.
204
205       You can see the context of a file using the -Z option to ls
206
207       Policy governs the access  confined  processes  have  to  these  files.
208       SELinux nagios_unconfined_plugin policy is very flexible allowing users
209       to setup their nagios_unconfined_plugin processes in as secure a method
210       as possible.
211
212       The following file types are defined for nagios_unconfined_plugin:
213
214
215
216       nagios_unconfined_plugin_exec_t
217
218       -  Set files with the nagios_unconfined_plugin_exec_t type, if you want
219       to transition an executable to the nagios_unconfined_plugin_t domain.
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

COMMANDS

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.
