6 wireshark_selinux - Security Enhanced Linux Policy for the wireshark
7 processes
8
10 Security-Enhanced Linux secures the wireshark processes via flexible
11 mandatory access control.
12
13 The wireshark processes execute with the wireshark_t SELinux type. You
14 can check if you have these processes running by executing the ps com‐
15 mand with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep wireshark_t
20
21
22
24 The wireshark_t SELinux type can be entered via the wireshark_exec_t
25 file type.
26
27 The default entrypoint paths for the wireshark_t domain are the follow‐
28 ing:
29
30 /usr/bin/tshark, /usr/bin/wireshark
31
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 wireshark policy is very flexible allowing users to setup their wire‐
40 shark processes in as secure a method as possible.
41
42 The following process types are defined for wireshark:
43
44 wireshark_t
45
46 Note: semanage permissive -a wireshark_t can be used to make the
47 process type wireshark_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
51
53 SELinux policy is customizable based on least access required. wire‐
54 shark policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run wireshark with the tightest access
56 possible.
57
58
59
60 If you want to allow users to resolve user passwd entries directly from
61 ldap rather then using a sssd server, you must turn on the authlo‐
62 gin_nsswitch_use_ldap boolean. Disabled by default.
63
64 setsebool -P authlogin_nsswitch_use_ldap 1
65
66
67
68 If you want to deny all system processes and Linux users to use blue‐
69 tooth wireless technology, you must turn on the deny_bluetooth boolean.
70 Enabled by default.
71
72 setsebool -P deny_bluetooth 1
73
74
75
76 If you want to allow all domains to execute in fips_mode, you must turn
77 on the fips_mode boolean. Enabled by default.
78
79 setsebool -P fips_mode 1
80
81
82
83 If you want to allow confined applications to run with kerberos, you
84 must turn on the kerberos_enabled boolean. Disabled by default.
85
86 setsebool -P kerberos_enabled 1
87
88
89
90 If you want to allow system to run with NIS, you must turn on the
91 nis_enabled boolean. Disabled by default.
92
93 setsebool -P nis_enabled 1
94
95
96
97 If you want to allow confined applications to use nscd shared memory,
98 you must turn on the nscd_use_shm boolean. Disabled by default.
99
100 setsebool -P nscd_use_shm 1
101
102
103
104 If you want to allow regular users direct dri device access, you must
105 turn on the selinuxuser_direct_dri_enabled boolean. Disabled by
106 default.
107
108 setsebool -P selinuxuser_direct_dri_enabled 1
109
110
111
112 If you want to allows clients to write to the X server shared memory
113 segments, you must turn on the xserver_clients_write_xshm boolean. Dis‐
114 abled by default.
115
116 setsebool -P xserver_clients_write_xshm 1
117
118
119
121 The SELinux process type wireshark_t can manage files labeled with the
122 following file types. The paths listed are the default paths for these
123 file types. Note the processes UID still need to have DAC permissions.

183 SELinux requires files to have an extended attribute to define the file
184 type.
185
186 You can see the context of a file using the -Z option to ls
187
188 Policy governs the access confined processes have to these files.
189 SELinux wireshark policy is very flexible allowing users to setup their
190 wireshark processes in as secure a method as possible.
191
192 STANDARD FILE CONTEXT
193
194 SELinux defines the file context types for the wireshark, if you wanted
195 to store files with these types in a diffent paths, you need to execute
196 the semanage command to sepecify alternate labeling and then use
197 restorecon to put the labels on disk.
198
199 semanage fcontext -a -t wireshark_tmpfs_t '/srv/mywireshark_con‐
200 tent(/.*)?'
201 restorecon -R -v /srv/mywireshark_content
202
203 Note: SELinux often uses regular expressions to specify labels that
204 match multiple files.
205
206 The following file types are defined for wireshark:
207
208
209
210 wireshark_exec_t
211
212 - Set files with the wireshark_exec_t type, if you want to transition
213 an executable to the wireshark_t domain.
214
215
216 Paths:
217 /usr/bin/tshark, /usr/bin/wireshark
218
219
220 wireshark_home_t
221
222 - Set files with the wireshark_home_t type, if you want to store wire‐
223 shark files in the users home directory.
224
225
226
227 wireshark_tmp_t
228
229 - Set files with the wireshark_tmp_t type, if you want to store wire‐
230 shark temporary files in the /tmp directories.
231
232
233
234 wireshark_tmpfs_t
235
236 - Set files with the wireshark_tmpfs_t type, if you want to store wire‐
237 shark files on a tmpfs file system.
238
239
240
241 Note: File context can be temporarily modified with the chcon command.
242 If you want to permanently change the file context you need to use the
243 semanage fcontext command. This will modify the SELinux labeling data‐
244 base. You will need to use restorecon to apply the labels.
245
246
248 semanage fcontext can also be used to manipulate default file context
249 mappings.
250
251 semanage permissive can also be used to manipulate whether or not a
252 process type is permissive.
253
254 semanage module can also be used to enable/disable/install/remove pol‐
255 icy modules.
256
257 semanage boolean can also be used to manipulate the booleans
258
259
260 system-config-selinux is a GUI tool available to customize SELinux pol‐
261 icy settings.
