6 NetworkManager_selinux - Security Enhanced Linux Policy for the Net‐
7 workManager processes
8
10 Security-Enhanced Linux secures the NetworkManager processes via flexi‐
11 ble mandatory access control.
12 The NetworkManager processes execute with the NetworkManager_t SELinux
14 type. You can check if you have these processes running by executing
15 the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep NetworkManager_t
20
24 The NetworkManager_t SELinux type can be entered via the NetworkMan‐
25 ager_exec_t file type.
26 The default entrypoint paths for the NetworkManager_t domain are the
28 following:
29 /usr/libexec/nm-dispatcher.*, /usr/bin/teamd, /usr/sbin/wicd,
31 /usr/bin/NetworkManager, /usr/bin/wpa_supplicant, /usr/sbin/NetworkMan‐
32 ager, /usr/sbin/wpa_supplicant, /usr/sbin/nm-system-settings,
33 /usr/sbin/NetworkManagerDispatcher
34
36 SELinux defines process types (domains) for each process running on the
37 system
38 You can see the context of a process using the -Z option to ps
40 Policy governs the access confined processes have to files. SELinux
42 NetworkManager policy is very flexible allowing users to setup their
43 NetworkManager processes in as secure a method as possible.
44 The following process types are defined for NetworkManager:
46 NetworkManager_t, NetworkManager_ssh_t
48 Note: semanage permissive -a NetworkManager_t can be used to make the
50 process type NetworkManager_t permissive. SELinux does not deny access
51 to permissive process types, but the AVC (SELinux denials) messages are
52 still generated.
53
56 SELinux policy is customizable based on least access required. Net‐
57 workManager policy is extremely flexible and has several booleans that
58 allow you to manipulate the policy and run NetworkManager with the
59 tightest access possible.
60 If you want to deny all system processes and Linux users to use blue‐
64 tooth wireless technology, you must turn on the deny_bluetooth boolean.
65 Enabled by default.
66 setsebool -P deny_bluetooth 1
68 If you want to deny any process from ptracing or debugging any other
72 processes, you must turn on the deny_ptrace boolean. Enabled by de‐
73 fault.
74 setsebool -P deny_ptrace 1
76 If you want to allow all domains to execute in fips_mode, you must turn
80 on the fips_mode boolean. Enabled by default.
81 setsebool -P fips_mode 1
83 If you want to support ecryptfs home directories, you must turn on the
87 use_ecryptfs_home_dirs boolean. Disabled by default.
88 setsebool -P use_ecryptfs_home_dirs 1
90 If you want to support NFS home directories, you must turn on the
94 use_nfs_home_dirs boolean. Disabled by default.
95 setsebool -P use_nfs_home_dirs 1
97 If you want to support SAMBA home directories, you must turn on the
101 use_samba_home_dirs boolean. Disabled by default.
102 setsebool -P use_samba_home_dirs 1
104 If you want to allow xguest users to configure Network Manager and con‐
108 nect to apache ports, you must turn on the xguest_connect_network bool‐
109 ean. Enabled by default.
110 setsebool -P xguest_connect_network 1

116 The SELinux process type NetworkManager_t can manage files labeled with
117 the following file types. The paths listed are the default paths for
118 these file types. Note the processes UID still need to have DAC per‐
119 missions.

242 SELinux requires files to have an extended attribute to define the file
243 type.
244 You can see the context of a file using the -Z option to ls
246 Policy governs the access confined processes have to these files.
248 SELinux NetworkManager policy is very flexible allowing users to setup
249 their NetworkManager processes in as secure a method as possible.
250 EQUIVALENCE DIRECTORIES
252 NetworkManager policy stores data with multiple different file context
255 types under the /var/run/NetworkManager directory. If you would like
256 to store the data in a different directory you can use the semanage
257 command to create an equivalence mapping. If you wanted to store this
258 data under the /srv directory you would execute the following command:
259 semanage fcontext -a -e /var/run/NetworkManager /srv/NetworkManager
261 restorecon -R -v /srv/NetworkManager
262 NetworkManager policy stores data with multiple different file context
264 types under the /var/run/wpa_supplicant directory. If you would like
265 to store the data in a different directory you can use the semanage
266 command to create an equivalence mapping. If you wanted to store this
267 data under the /srv directory you would execute the following command:
268 semanage fcontext -a -e /var/run/wpa_supplicant /srv/wpa_supplicant
270 restorecon -R -v /srv/wpa_supplicant
271 STANDARD FILE CONTEXT
273 SELinux defines the file context types for the NetworkManager, if you
275 wanted to store files with these types in a diffent paths, you need to
276 execute the semanage command to sepecify alternate labeling and then
277 use restorecon to put the labels on disk.
278 semanage fcontext -a -t NetworkManager_var_run_t '/srv/myNetworkMan‐
280 ager_content(/.*)?'
281 restorecon -R -v /srv/myNetworkManager_content
282 Note: SELinux often uses regular expressions to specify labels that
284 match multiple files.
285 The following file types are defined for NetworkManager:
287 NetworkManager_etc_rw_t
291 - Set files with the NetworkManager_etc_rw_t type, if you want to treat
293 the files as NetworkManager etc read/write content.
294 Paths:
297 /etc/NetworkManager/system-connections(/.*)?, /etc/NetworkMan‐
298 ager/NetworkManager.conf
299 NetworkManager_etc_t
302 - Set files with the NetworkManager_etc_t type, if you want to store
304 NetworkManager files in the /etc directories.
305 NetworkManager_exec_t
309 - Set files with the NetworkManager_exec_t type, if you want to transi‐
311 tion an executable to the NetworkManager_t domain.
312 Paths:
315 /usr/libexec/nm-dispatcher.*, /usr/bin/teamd, /usr/sbin/wicd,
316 /usr/bin/NetworkManager, /usr/bin/wpa_supplicant, /usr/sbin/Net‐
317 workManager, /usr/sbin/wpa_supplicant, /usr/sbin/nm-system-set‐
318 tings, /usr/sbin/NetworkManagerDispatcher
319 NetworkManager_initrc_exec_t
322 - Set files with the NetworkManager_initrc_exec_t type, if you want to
324 transition an executable to the NetworkManager_initrc_t domain.
325 Paths:
328 /etc/NetworkManager/dispatcher.d(/.*)?, /usr/lib/NetworkMan‐
329 ager/dispatcher.d(/.*)?, /etc/rc.d/init.d/wicd
330 NetworkManager_log_t
333 - Set files with the NetworkManager_log_t type, if you want to treat
335 the data as NetworkManager log data, usually stored under the /var/log
336 directory.
337 Paths:
340 /var/log/wicd.*, /var/log/wpa_supplicant.*
341 NetworkManager_tmp_t
344 - Set files with the NetworkManager_tmp_t type, if you want to store
346 NetworkManager temporary files in the /tmp directories.
347 NetworkManager_unit_file_t
351 - Set files with the NetworkManager_unit_file_t type, if you want to
353 treat the files as NetworkManager unit content.
354 Paths:
357 /usr/lib/systemd/system/NetworkManager.*, /usr/lib/systemd/sys‐
358 tem/nm-cloud-setup.(service|timer)
359 NetworkManager_var_lib_t
362 - Set files with the NetworkManager_var_lib_t type, if you want to
364 store the NetworkManager files under the /var/lib directory.
365 Paths:
368 /var/lib/wicd(/.*)?, /var/lib/NetworkManager(/.*)?,
369 /etc/dhcp/wired-settings.conf, /etc/wicd/wired-settings.conf,
370 /etc/dhcp/manager-settings.conf, /etc/wicd/manager-settings.conf,
371 /etc/dhcp/wireless-settings.conf, /etc/wicd/wireless-settings.conf
372 NetworkManager_var_run_t
375 - Set files with the NetworkManager_var_run_t type, if you want to
377 store the NetworkManager files under the /run or /var/run directory.
378 Paths:
381 /var/run/teamd(/.*)?, /var/run/nm-xl2tpd.conf.*, /var/run/nm-
382 dhclient.*, /var/run/NetworkManager(/.*)?, /var/run/wpa_suppli‐
383 cant(/.*)?, /var/run/wicd.pid, /var/run/NetworkManager.pid,
384 /var/run/nm-dns-dnsmasq.conf, /var/run/wpa_supplicant-global
385 Note: File context can be temporarily modified with the chcon command.
388 If you want to permanently change the file context you need to use the
389 semanage fcontext command. This will modify the SELinux labeling data‐
390 base. You will need to use restorecon to apply the labels.
391
394 semanage fcontext can also be used to manipulate default file context
395 mappings.
396 semanage permissive can also be used to manipulate whether or not a
398 process type is permissive.
399 semanage module can also be used to enable/disable/install/remove pol‐
401 icy modules.
402 semanage boolean can also be used to manipulate the booleans
404 system-config-selinux is a GUI tool available to customize SELinux pol‐
407 icy settings.
