6 unconfined_munin_plugin_selinux - Security Enhanced Linux Policy for
7 the unconfined_munin_plugin processes
8
10 Security-Enhanced Linux secures the unconfined_munin_plugin processes
11 via flexible mandatory access control.
12 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 For example:
18 ps -eZ | grep unconfined_munin_plugin_t
20
24 The unconfined_munin_plugin_t SELinux type can be entered via the
25 unconfined_munin_plugin_exec_t file type.
26 The default entrypoint paths for the unconfined_munin_plugin_t domain
28 are the following:
29 /usr/share/munin/plugins/.*
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 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 The following process types are defined for unconfined_munin_plugin:
44 unconfined_munin_plugin_t
46 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
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 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 setsebool -P deny_execmem 1
67 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 setsebool -P fips_mode 1
74 If you want to control the ability to mmap a low area of the address
78 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
79 the mmap_low_allowed boolean. Disabled by default.
80 setsebool -P mmap_low_allowed 1
82 If you want to allow confined applications to use nscd shared memory,
86 you must turn on the nscd_use_shm boolean. Enabled by default.
87 setsebool -P nscd_use_shm 1
89 If you want to disable kernel module loading, you must turn on the
93 secure_mode_insmod boolean. Enabled by default.
94 setsebool -P secure_mode_insmod 1
96 If you want to allow unconfined executables to make their heap memory
100 executable. Doing this is a really bad idea. Probably indicates a
101 badly coded executable, but could indicate an attack. This executable
102 should be reported in bugzilla, you must turn on the selin‐
103 uxuser_execheap boolean. Disabled by default.
104 setsebool -P selinuxuser_execheap 1
106 If you want to allow unconfined executables to make their stack exe‐
110 cutable. This should never, ever be necessary. Probably indicates a
111 badly coded executable, but could indicate an attack. This executable
112 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
113 stack boolean. Enabled by default.
114 setsebool -P selinuxuser_execstack 1
116
120 The SELinux process type unconfined_munin_plugin_t can manage files
121 labeled with the following file types. The paths listed are the
122 default paths for these file types. Note the processes UID still need
123 to have DAC permissions.
124 file_type
126 all files on the system
128
131 SELinux requires files to have an extended attribute to define the file
132 type.
133 You can see the context of a file using the -Z option to ls
135 Policy governs the access confined processes have to these files.
137 SELinux unconfined_munin_plugin policy is very flexible allowing users
138 to setup their unconfined_munin_plugin processes in as secure a method
139 as possible.
140 STANDARD FILE CONTEXT
142 SELinux defines the file context types for the unconfined_munin_plugin,
144 if you wanted to store files with these types in a diffent paths, you
145 need to execute the semanage command to sepecify alternate labeling and
146 then use restorecon to put the labels on disk.
147 semanage fcontext -a -t unconfined_munin_plugin_tmp_t '/srv/myuncon‐
149 fined_munin_plugin_content(/.*)?'
150 restorecon -R -v /srv/myunconfined_munin_plugin_content
151 Note: SELinux often uses regular expressions to specify labels that
153 match multiple files.
154 The following file types are defined for unconfined_munin_plugin:
156 unconfined_munin_plugin_exec_t
160 - Set files with the unconfined_munin_plugin_exec_t type, if you want
162 to transition an executable to the unconfined_munin_plugin_t domain.
163 unconfined_munin_plugin_tmp_t
167 - Set files with the unconfined_munin_plugin_tmp_t type, if you want to
169 store unconfined munin plugin temporary files in the /tmp directories.
170 Note: File context can be temporarily modified with the chcon command.
174 If you want to permanently change the file context you need to use the
175 semanage fcontext command. This will modify the SELinux labeling data‐
176 base. You will need to use restorecon to apply the labels.
177
180 semanage fcontext can also be used to manipulate default file context
181 mappings.
182 semanage permissive can also be used to manipulate whether or not a
184 process type is permissive.
185 semanage module can also be used to enable/disable/install/remove pol‐
187 icy modules.
188 semanage boolean can also be used to manipulate the booleans
190 system-config-selinux is a GUI tool available to customize SELinux pol‐
193 icy settings.
