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 allow all domains to execute in fips_mode, you must turn
71       on the fips_mode boolean. Enabled by default.
72
73       setsebool -P fips_mode 1
74
75
76
77       If  you want to allow syslogd the ability to call nagios plugins. It is
78       turned on by omprog rsyslog plugin, you must turn on  the  logging_sys‐
79       logd_run_nagios_plugins boolean. Disabled by default.
80
81       setsebool -P logging_syslogd_run_nagios_plugins 1
82
83
84
85       If  you  want  to control the ability to mmap a low area of the address
86       space, as configured by /proc/sys/vm/mmap_min_addr, you  must  turn  on
87       the mmap_low_allowed boolean. Disabled by default.
88
89       setsebool -P mmap_low_allowed 1
90
91
92
93       If  you  want  to  disable  kernel module loading, you must turn on the
94       secure_mode_insmod boolean. Enabled by default.
95
96       setsebool -P secure_mode_insmod 1
97
98
99
100       If you want to allow unconfined executables to make their  heap  memory
101       executable.   Doing  this  is  a  really bad idea. Probably indicates a
102       badly coded executable, but could indicate an attack.  This  executable
103       should   be   reported  in  bugzilla,  you  must  turn  on  the  selin‐
104       uxuser_execheap boolean. Disabled by default.
105
106       setsebool -P selinuxuser_execheap 1
107
108
109
110       If you want to allow unconfined executables to make  their  stack  exe‐
111       cutable.   This  should  never, ever be necessary. Probably indicates a
112       badly coded executable, but could indicate an attack.  This  executable
113       should  be reported in bugzilla, you must turn on the selinuxuser_exec‐
114       stack boolean. Enabled by default.
115
116       setsebool -P selinuxuser_execstack 1

MANAGED FILES

121       The SELinux process type nagios_unconfined_plugin_t  can  manage  files
122       labeled  with  the  following  file  types.   The  paths listed are the
123       default paths for these file types.  Note the processes UID still  need
124       to have DAC permissions.
125
126       file_type
127
128            all files on the system
129
130

FILE CONTEXTS

132       SELinux requires files to have an extended attribute to define the file
133       type.
134
135       You can see the context of a file using the -Z option to ls
136
137       Policy governs the access  confined  processes  have  to  these  files.
138       SELinux nagios_unconfined_plugin policy is very flexible allowing users
139       to setup their nagios_unconfined_plugin processes in as secure a method
140       as possible.
141
142       The following file types are defined for nagios_unconfined_plugin:
143
144
145
146       nagios_unconfined_plugin_exec_t
147
148       -  Set files with the nagios_unconfined_plugin_exec_t type, if you want
149       to transition an executable to the nagios_unconfined_plugin_t domain.
150
151
152
153       Note: File context can be temporarily modified with the chcon  command.
154       If  you want to permanently change the file context you need to use the
155       semanage fcontext command.  This will modify the SELinux labeling data‐
156       base.  You will need to use restorecon to apply the labels.
157
158

COMMANDS

160       semanage  fcontext  can also be used to manipulate default file context
161       mappings.
162
163       semanage permissive can also be used to manipulate  whether  or  not  a
164       process type is permissive.
165
166       semanage  module can also be used to enable/disable/install/remove pol‐
167       icy modules.
168
169       semanage boolean can also be used to manipulate the booleans
170
171
172       system-config-selinux is a GUI tool available to customize SELinux pol‐
173       icy settings.
