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 allow users to resolve user passwd entries directly from
64 ldap rather then using a sssd server, you must turn on the authlo‐
65 gin_nsswitch_use_ldap boolean. Disabled by default.
66 setsebool -P authlogin_nsswitch_use_ldap 1
68 If you want to deny all system processes and Linux users to use blue‐
72 tooth wireless technology, you must turn on the deny_bluetooth boolean.
73 Enabled by default.
74 setsebool -P deny_bluetooth 1
76 If you want to deny any process from ptracing or debugging any other
80 processes, you must turn on the deny_ptrace boolean. Enabled by
81 default.
82 setsebool -P deny_ptrace 1
84 If you want to allow all domains to execute in fips_mode, you must turn
88 on the fips_mode boolean. Enabled by default.
89 setsebool -P fips_mode 1
91 If you want to allow confined applications to run with kerberos, you
95 must turn on the kerberos_enabled boolean. Disabled by default.
96 setsebool -P kerberos_enabled 1
98 If you want to allow system to run with NIS, you must turn on the
102 nis_enabled boolean. Disabled by default.
103 setsebool -P nis_enabled 1
105 If you want to allow confined applications to use nscd shared memory,
109 you must turn on the nscd_use_shm boolean. Disabled by default.
110 setsebool -P nscd_use_shm 1
112 If you want to support ecryptfs home directories, you must turn on the
116 use_ecryptfs_home_dirs boolean. Disabled by default.
117 setsebool -P use_ecryptfs_home_dirs 1
119 If you want to support NFS home directories, you must turn on the
123 use_nfs_home_dirs boolean. Enabled by default.
124 setsebool -P use_nfs_home_dirs 1
126 If you want to support SAMBA home directories, you must turn on the
130 use_samba_home_dirs boolean. Disabled by default.
131 setsebool -P use_samba_home_dirs 1
133 If you want to allow xguest users to configure Network Manager and con‐
137 nect to apache ports, you must turn on the xguest_connect_network bool‐
138 ean. Enabled by default.
139 setsebool -P xguest_connect_network 1

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

304 SELinux requires files to have an extended attribute to define the file
305 type.
306 You can see the context of a file using the -Z option to ls
308 Policy governs the access confined processes have to these files.
310 SELinux NetworkManager policy is very flexible allowing users to setup
311 their NetworkManager processes in as secure a method as possible.
312 EQUIVALENCE DIRECTORIES
314 NetworkManager policy stores data with multiple different file context
317 types under the /var/run/NetworkManager directory. If you would like
318 to store the data in a different directory you can use the semanage
319 command to create an equivalence mapping. If you wanted to store this
320 data under the /srv dirctory you would execute the following command:
321 semanage fcontext -a -e /var/run/NetworkManager /srv/NetworkManager
323 restorecon -R -v /srv/NetworkManager
324 NetworkManager policy stores data with multiple different file context
326 types under the /var/run/wpa_supplicant directory. If you would like
327 to store the data in a different directory you can use the semanage
328 command to create an equivalence mapping. If you wanted to store this
329 data under the /srv dirctory you would execute the following command:
330 semanage fcontext -a -e /var/run/wpa_supplicant /srv/wpa_supplicant
332 restorecon -R -v /srv/wpa_supplicant
333 STANDARD FILE CONTEXT
335 SELinux defines the file context types for the NetworkManager, if you
337 wanted to store files with these types in a diffent paths, you need to
338 execute the semanage command to sepecify alternate labeling and then
339 use restorecon to put the labels on disk.
340 semanage fcontext -a -t NetworkManager_var_run_t '/srv/myNetworkMan‐
342 ager_content(/.*)?'
343 restorecon -R -v /srv/myNetworkManager_content
344 Note: SELinux often uses regular expressions to specify labels that
346 match multiple files.
347 The following file types are defined for NetworkManager:
349 NetworkManager_etc_rw_t
353 - Set files with the NetworkManager_etc_rw_t type, if you want to treat
355 the files as NetworkManager etc read/write content.
356 Paths:
359 /etc/NetworkManager/system-connections(/.*)?, /etc/NetworkMan‐
360 ager/NetworkManager.conf
361 NetworkManager_etc_t
364 - Set files with the NetworkManager_etc_t type, if you want to store
366 NetworkManager files in the /etc directories.
367 NetworkManager_exec_t
371 - Set files with the NetworkManager_exec_t type, if you want to transi‐
373 tion an executable to the NetworkManager_t domain.
374 Paths:
377 /usr/libexec/nm-dispatcher.*, /usr/bin/teamd, /usr/sbin/wicd,
378 /usr/bin/NetworkManager, /usr/bin/wpa_supplicant, /usr/sbin/Net‐
379 workManager, /usr/sbin/wpa_supplicant, /usr/sbin/nm-system-set‐
380 tings, /usr/sbin/NetworkManagerDispatcher
381 NetworkManager_initrc_exec_t
384 - Set files with the NetworkManager_initrc_exec_t type, if you want to
386 transition an executable to the NetworkManager_initrc_t domain.
387 Paths:
390 /etc/NetworkManager/dispatcher.d(/.*)?, /etc/rc.d/init.d/wicd
391 NetworkManager_log_t
394 - Set files with the NetworkManager_log_t type, if you want to treat
396 the data as NetworkManager log data, usually stored under the /var/log
397 directory.
398 Paths:
401 /var/log/wicd.*, /var/log/wpa_supplicant.*
402 NetworkManager_tmp_t
405 - Set files with the NetworkManager_tmp_t type, if you want to store
407 NetworkManager temporary files in the /tmp directories.
408 NetworkManager_unit_file_t
412 - Set files with the NetworkManager_unit_file_t type, if you want to
414 treat the files as NetworkManager unit content.
415 NetworkManager_var_lib_t
419 - Set files with the NetworkManager_var_lib_t type, if you want to
421 store the NetworkManager files under the /var/lib directory.
422 Paths:
425 /var/lib/wicd(/.*)?, /var/lib/NetworkManager(/.*)?,
426 /etc/dhcp/wired-settings.conf, /etc/wicd/wired-settings.conf,
427 /etc/dhcp/manager-settings.conf, /etc/wicd/manager-settings.conf,
428 /etc/dhcp/wireless-settings.conf, /etc/wicd/wireless-settings.conf
429 NetworkManager_var_run_t
432 - Set files with the NetworkManager_var_run_t type, if you want to
434 store the NetworkManager files under the /run or /var/run directory.
435 Paths:
438 /var/run/teamd(/.*)?, /var/run/nm-xl2tpd.conf.*, /var/run/nm-
439 dhclient.*, /var/run/NetworkManager(/.*)?, /var/run/wpa_suppli‐
440 cant(/.*)?, /var/run/wicd.pid, /var/run/NetworkManager.pid,
441 /var/run/nm-dns-dnsmasq.conf, /var/run/wpa_supplicant-global
442 Note: File context can be temporarily modified with the chcon command.
445 If you want to permanently change the file context you need to use the
446 semanage fcontext command. This will modify the SELinux labeling data‐
447 base. You will need to use restorecon to apply the labels.
448
451 semanage fcontext can also be used to manipulate default file context
452 mappings.
453 semanage permissive can also be used to manipulate whether or not a
455 process type is permissive.
456 semanage module can also be used to enable/disable/install/remove pol‐
458 icy modules.
459 semanage boolean can also be used to manipulate the booleans
461 system-config-selinux is a GUI tool available to customize SELinux pol‐
464 icy settings.
