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 na‐
25       gios_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
40       setup 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.   na‐
55       gios_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. Disabled by default.
65
66       setsebool -P deny_execmem 1
67
68
69
70       If you want to control the ability to mmap a low area  of  the  address
71       space,  as  configured  by /proc/sys/vm/mmap_min_addr, you must turn on
72       the mmap_low_allowed boolean. Disabled by default.
73
74       setsebool -P mmap_low_allowed 1
75
76
77
78       If you want to disable kernel module loading, you must turn on the  se‐
79       cure_mode_insmod boolean. Disabled by default.
80
81       setsebool -P secure_mode_insmod 1
82
83
84
85       If  you  want to allow unconfined executables to make their heap memory
86       executable.  Doing this is a really  bad  idea.  Probably  indicates  a
87       badly  coded  executable, but could indicate an attack. This executable
88       should be reported in bugzilla, you must turn  on  the  selinuxuser_ex‐
89       echeap boolean. Disabled by default.
90
91       setsebool -P selinuxuser_execheap 1
92
93
94
95       If  you  want  to allow unconfined executables to make their stack exe‐
96       cutable.  This should never, ever be necessary.  Probably  indicates  a
97       badly  coded  executable, but could indicate an attack. This executable
98       should be reported in bugzilla, you must turn on the  selinuxuser_exec‐
99       stack boolean. Enabled by default.
100
101       setsebool -P selinuxuser_execstack 1

MANAGED FILES

106       The  SELinux  process  type nagios_unconfined_plugin_t can manage files
107       labeled with the following file types.  The paths listed  are  the  de‐
108       fault paths for these file types.  Note the processes UID still need to
109       have DAC permissions.
110
111       file_type
112
113            all files on the system
114
115

FILE CONTEXTS

117       SELinux requires files to have an extended attribute to define the file
118       type.
119
120       You can see the context of a file using the -Z option to ls
121
122       Policy  governs  the  access  confined  processes  have to these files.
123       SELinux nagios_unconfined_plugin policy is very flexible allowing users
124       to setup their nagios_unconfined_plugin processes in as secure a method
125       as possible.
126
127       STANDARD FILE CONTEXT
128
129       SELinux  defines  the  file  context  types   for   the   nagios_uncon‐
130       fined_plugin,  if  you wanted to store files with these types in a dif‐
131       ferent paths, you need to execute the semanage command to  specify  al‐
132       ternate labeling and then use restorecon to put the labels on disk.
133
134       semanage   fcontext  -a  -t  nagios_unconfined_plugin_exec_t  '/srv/na‐
135       gios_unconfined_plugin/content(/.*)?'
136       restorecon -R -v /srv/mynagios_unconfined_plugin_content
137
138       Note: SELinux often uses regular expressions  to  specify  labels  that
139       match multiple files.
140
141       The following file types are defined for nagios_unconfined_plugin:
142
143
144
145       nagios_unconfined_plugin_exec_t
146
147       -  Set files with the nagios_unconfined_plugin_exec_t type, if you want
148       to transition an executable to the nagios_unconfined_plugin_t domain.
149
150
151
152       Note: File context can be temporarily modified with the chcon  command.
153       If  you want to permanently change the file context you need to use the
154       semanage fcontext command.  This will modify the SELinux labeling data‐
155       base.  You will need to use restorecon to apply the labels.

157

COMMANDS

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