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 any process from ptracing or debugging any other
72 processes, you must turn on the deny_ptrace boolean. Enabled by
73 default.
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 allow confined applications to run with kerberos, you
87 must turn on the kerberos_enabled boolean. Enabled by default.
88 setsebool -P kerberos_enabled 1
90 If you want to allow system to run with NIS, you must turn on the
94 nis_enabled boolean. Disabled by default.
95 setsebool -P nis_enabled 1
97 If you want to allow confined applications to use nscd shared memory,
101 you must turn on the nscd_use_shm boolean. Enabled by default.
102 setsebool -P nscd_use_shm 1
104 If you want to support ecryptfs home directories, you must turn on the
108 use_ecryptfs_home_dirs boolean. Disabled by default.
109 setsebool -P use_ecryptfs_home_dirs 1
111 If you want to support NFS home directories, you must turn on the
115 use_nfs_home_dirs boolean. Disabled by default.
116 setsebool -P use_nfs_home_dirs 1
118 If you want to support SAMBA home directories, you must turn on the
122 use_samba_home_dirs boolean. Disabled by default.
123 setsebool -P use_samba_home_dirs 1
125 If you want to allow xguest users to configure Network Manager and con‐
129 nect to apache ports, you must turn on the xguest_connect_network bool‐
130 ean. Enabled by default.
131 setsebool -P xguest_connect_network 1

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

289 SELinux requires files to have an extended attribute to define the file
290 type.
291 You can see the context of a file using the -Z option to ls
293 Policy governs the access confined processes have to these files.
295 SELinux NetworkManager policy is very flexible allowing users to setup
296 their NetworkManager processes in as secure a method as possible.
297 EQUIVALENCE DIRECTORIES
299 NetworkManager policy stores data with multiple different file context
302 types under the /var/run/NetworkManager directory. If you would like
303 to store the data in a different directory you can use the semanage
304 command to create an equivalence mapping. If you wanted to store this
305 data under the /srv dirctory you would execute the following command:
306 semanage fcontext -a -e /var/run/NetworkManager /srv/NetworkManager
308 restorecon -R -v /srv/NetworkManager
309 NetworkManager policy stores data with multiple different file context
311 types under the /var/run/wpa_supplicant directory. If you would like
312 to store the data in a different directory you can use the semanage
313 command to create an equivalence mapping. If you wanted to store this
314 data under the /srv dirctory you would execute the following command:
315 semanage fcontext -a -e /var/run/wpa_supplicant /srv/wpa_supplicant
317 restorecon -R -v /srv/wpa_supplicant
318 STANDARD FILE CONTEXT
320 SELinux defines the file context types for the NetworkManager, if you
322 wanted to store files with these types in a diffent paths, you need to
323 execute the semanage command to sepecify alternate labeling and then
324 use restorecon to put the labels on disk.
325 semanage fcontext -a -t NetworkManager_var_run_t '/srv/myNetworkMan‐
327 ager_content(/.*)?'
328 restorecon -R -v /srv/myNetworkManager_content
329 Note: SELinux often uses regular expressions to specify labels that
331 match multiple files.
332 The following file types are defined for NetworkManager:
334 NetworkManager_etc_rw_t
338 - Set files with the NetworkManager_etc_rw_t type, if you want to treat
340 the files as NetworkManager etc read/write content.
341 Paths:
344 /etc/NetworkManager/system-connections(/.*)?, /etc/NetworkMan‐
345 ager/NetworkManager.conf
346 NetworkManager_etc_t
349 - Set files with the NetworkManager_etc_t type, if you want to store
351 NetworkManager files in the /etc directories.
352 NetworkManager_exec_t
356 - Set files with the NetworkManager_exec_t type, if you want to transi‐
358 tion an executable to the NetworkManager_t domain.
359 Paths:
362 /usr/libexec/nm-dispatcher.*, /usr/bin/teamd, /usr/sbin/wicd,
363 /usr/bin/NetworkManager, /usr/bin/wpa_supplicant, /usr/sbin/Net‐
364 workManager, /usr/sbin/wpa_supplicant, /usr/sbin/nm-system-set‐
365 tings, /usr/sbin/NetworkManagerDispatcher
366 NetworkManager_initrc_exec_t
369 - Set files with the NetworkManager_initrc_exec_t type, if you want to
371 transition an executable to the NetworkManager_initrc_t domain.
372 Paths:
375 /etc/NetworkManager/dispatcher.d(/.*)?, /etc/rc.d/init.d/wicd
376 NetworkManager_log_t
379 - Set files with the NetworkManager_log_t type, if you want to treat
381 the data as NetworkManager log data, usually stored under the /var/log
382 directory.
383 Paths:
386 /var/log/wicd.*, /var/log/wpa_supplicant.*
387 NetworkManager_tmp_t
390 - Set files with the NetworkManager_tmp_t type, if you want to store
392 NetworkManager temporary files in the /tmp directories.
393 NetworkManager_unit_file_t
397 - Set files with the NetworkManager_unit_file_t type, if you want to
399 treat the files as NetworkManager unit content.
400 NetworkManager_var_lib_t
404 - Set files with the NetworkManager_var_lib_t type, if you want to
406 store the NetworkManager files under the /var/lib directory.
407 Paths:
410 /var/lib/wicd(/.*)?, /var/lib/NetworkManager(/.*)?,
411 /etc/dhcp/wired-settings.conf, /etc/wicd/wired-settings.conf,
412 /etc/dhcp/manager-settings.conf, /etc/wicd/manager-settings.conf,
413 /etc/dhcp/wireless-settings.conf, /etc/wicd/wireless-settings.conf
414 NetworkManager_var_run_t
417 - Set files with the NetworkManager_var_run_t type, if you want to
419 store the NetworkManager files under the /run or /var/run directory.
420 Paths:
423 /var/run/teamd(/.*)?, /var/run/nm-xl2tpd.conf.*, /var/run/nm-
424 dhclient.*, /var/run/NetworkManager(/.*)?, /var/run/wpa_suppli‐
425 cant(/.*)?, /var/run/wicd.pid, /var/run/NetworkManager.pid,
426 /var/run/nm-dns-dnsmasq.conf, /var/run/wpa_supplicant-global
427 Note: File context can be temporarily modified with the chcon command.
430 If you want to permanently change the file context you need to use the
431 semanage fcontext command. This will modify the SELinux labeling data‐
432 base. You will need to use restorecon to apply the labels.
433
436 semanage fcontext can also be used to manipulate default file context
437 mappings.
438 semanage permissive can also be used to manipulate whether or not a
440 process type is permissive.
441 semanage module can also be used to enable/disable/install/remove pol‐
443 icy modules.
444 semanage boolean can also be used to manipulate the booleans
446 system-config-selinux is a GUI tool available to customize SELinux pol‐
449 icy settings.
