NAME

6       wireshark_selinux  -  Security  Enhanced Linux Policy for the wireshark
7       processes
8

DESCRIPTION

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

ENTRYPOINTS

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

PROCESS TYPES

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

BOOLEANS

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 deny all system processes and Linux users to  use  blue‐
61       tooth wireless technology, you must turn on the deny_bluetooth boolean.
62       Enabled by default.
63
64       setsebool -P deny_bluetooth 1
65
66
67
68       If you want to allow all domains to execute in fips_mode, you must turn
69       on the fips_mode boolean. Enabled by default.
70
71       setsebool -P fips_mode 1
72
73
74
75       If  you  want  to  allow  system  to run with NIS, you must turn on the
76       nis_enabled boolean. Disabled by default.
77
78       setsebool -P nis_enabled 1
79
80
81
82       If you want to allow regular users direct dri device access,  you  must
83       turn   on   the  selinuxuser_direct_dri_enabled  boolean.  Disabled  by
84       default.
85
86       setsebool -P selinuxuser_direct_dri_enabled 1
87
88
89
90       If you want to allows clients to write to the X  server  shared  memory
91       segments, you must turn on the xserver_clients_write_xshm boolean. Dis‐
92       abled by default.
93
94       setsebool -P xserver_clients_write_xshm 1

MANAGED FILES

99       The SELinux process type wireshark_t can manage files labeled with  the
100       following file types.  The paths listed are the default paths for these
101       file types.  Note the processes UID still need to have DAC permissions.
102

FILE CONTEXTS

152       SELinux requires files to have an extended attribute to define the file
153       type.
154
155       You can see the context of a file using the -Z option to ls
156
157       Policy  governs  the  access  confined  processes  have to these files.
158       SELinux wireshark policy is very flexible allowing users to setup their
159       wireshark processes in as secure a method as possible.
160
161       STANDARD FILE CONTEXT
162
163       SELinux defines the file context types for the wireshark, if you wanted
164       to store files with these types in a diffent paths, you need to execute
165       the  semanage  command  to  sepecify  alternate  labeling  and then use
166       restorecon to put the labels on disk.
167
168       semanage  fcontext  -a  -t   wireshark_tmpfs_t   '/srv/mywireshark_con‐
169       tent(/.*)?'
170       restorecon -R -v /srv/mywireshark_content
171
172       Note:  SELinux  often  uses  regular expressions to specify labels that
173       match multiple files.
174
175       The following file types are defined for wireshark:
176
177
178
179       wireshark_exec_t
180
181       - Set files with the wireshark_exec_t type, if you want  to  transition
182       an executable to the wireshark_t domain.
183
184
185       Paths:
186            /usr/bin/tshark, /usr/bin/wireshark
187
188
189       wireshark_home_t
190
191       -  Set files with the wireshark_home_t type, if you want to store wire‐
192       shark files in the users home directory.
193
194
195
196       wireshark_tmp_t
197
198       - Set files with the wireshark_tmp_t type, if you want to  store  wire‐
199       shark temporary files in the /tmp directories.
200
201
202
203       wireshark_tmpfs_t
204
205       - Set files with the wireshark_tmpfs_t type, if you want to store wire‐
206       shark files on a tmpfs file system.
207
208
209
210       Note: File context can be temporarily modified with the chcon  command.
211       If  you want to permanently change the file context you need to use the
212       semanage fcontext command.  This will modify the SELinux labeling data‐
213       base.  You will need to use restorecon to apply the labels.
214
215

COMMANDS

217       semanage  fcontext  can also be used to manipulate default file context
218       mappings.
219
220       semanage permissive can also be used to manipulate  whether  or  not  a
221       process type is permissive.
222
223       semanage  module can also be used to enable/disable/install/remove pol‐
224       icy modules.
225
226       semanage boolean can also be used to manipulate the booleans
227
228
229       system-config-selinux is a GUI tool available to customize SELinux pol‐
230       icy settings.
