NAME

6       unconfined_munin_plugin_selinux  -  Security  Enhanced Linux Policy for
7       the unconfined_munin_plugin processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the  unconfined_munin_plugin  processes
11       via flexible mandatory access control.
12
13       The   unconfined_munin_plugin   processes   execute   with  the  uncon‐
14       fined_munin_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 unconfined_munin_plugin_t

ENTRYPOINTS

24       The  unconfined_munin_plugin_t  SELinux type can be entered via the un‐
25       confined_munin_plugin_exec_t file type.
26
27       The default entrypoint paths for the  unconfined_munin_plugin_t  domain
28       are the following:
29
30       /usr/share/munin/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       unconfined_munin_plugin policy is very flexible allowing users to setup
40       their unconfined_munin_plugin processes in as secure a method as possi‐
41       ble.
42
43       The following process types are defined for unconfined_munin_plugin:
44
45       unconfined_munin_plugin_t
46
47       Note:  semanage  permissive -a unconfined_munin_plugin_t can be used to
48       make the process  type  unconfined_munin_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.   uncon‐
55       fined_munin_plugin  policy  is extremely flexible and has several bool‐
56       eans  that  allow  you  to  manipulate  the  policy  and   run   uncon‐
57       fined_munin_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 unconfined_munin_plugin_t can manage files la‐
107       beled with the following file types.  The paths listed are the  default
108       paths  for these file types.  Note the processes UID still need to have
109       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 unconfined_munin_plugin policy is very flexible allowing  users
124       to  setup their unconfined_munin_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 unconfined_munin_plugin,
130       if you wanted to store files with these types in a different paths, you
131       need to execute the semanage command to specify alternate labeling  and
132       then use restorecon to put the labels on disk.
133
134       semanage  fcontext  -a  -t  unconfined_munin_plugin_exec_t '/srv/uncon‐
135       fined_munin_plugin/content(/.*)?'
136       restorecon -R -v /srv/myunconfined_munin_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 unconfined_munin_plugin:
142
143
144
145       unconfined_munin_plugin_exec_t
146
147       -  Set  files with the unconfined_munin_plugin_exec_t type, if you want
148       to transition an executable to the unconfined_munin_plugin_t domain.
149
150
151
152       unconfined_munin_plugin_tmp_t
153
154       - Set files with the unconfined_munin_plugin_tmp_t type, if you want to
155       store unconfined munin plugin temporary files in the /tmp directories.
156
157
158
159       Note:  File context can be temporarily modified with the chcon command.
160       If you want to permanently change the file context you need to use  the
161       semanage fcontext command.  This will modify the SELinux labeling data‐
162       base.  You will need to use restorecon to apply the labels.
163
164

COMMANDS

166       semanage fcontext can also be used to manipulate default  file  context
167       mappings.
168
169       semanage  permissive  can  also  be used to manipulate whether or not a
170       process type is permissive.
171
172       semanage module can also be used to enable/disable/install/remove  pol‐
173       icy modules.
174
175       semanage boolean can also be used to manipulate the booleans
176
177
178       system-config-selinux is a GUI tool available to customize SELinux pol‐
179       icy settings.
