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 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 For example:
18 ps -eZ | grep wireshark_t
20
24 The wireshark_t SELinux type can be entered via the wireshark_exec_t
25 file type.
26 The default entrypoint paths for the wireshark_t domain are the follow‐
28 ing:
29 /usr/bin/tshark, /usr/bin/wireshark
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 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 The following process types are defined for wireshark:
43 wireshark_t
45 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
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 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 setsebool -P deny_bluetooth 1
65 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 setsebool -P fips_mode 1
72 If you want to allow system to run with NIS, you must turn on the
76 nis_enabled boolean. Disabled by default.
77 setsebool -P nis_enabled 1
79 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 setsebool -P selinuxuser_direct_dri_enabled 1
87 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 setsebool -P xserver_clients_write_xshm 1
95
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.

152 SELinux requires files to have an extended attribute to define the file
153 type.
154 You can see the context of a file using the -Z option to ls
156 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 STANDARD FILE CONTEXT
162 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 semanage fcontext -a -t wireshark_tmpfs_t '/srv/mywireshark_con‐
169 tent(/.*)?'
170 restorecon -R -v /srv/mywireshark_content
171 Note: SELinux often uses regular expressions to specify labels that
173 match multiple files.
174 The following file types are defined for wireshark:
176 wireshark_exec_t
180 - Set files with the wireshark_exec_t type, if you want to transition
182 an executable to the wireshark_t domain.
183 Paths:
186 /usr/bin/tshark, /usr/bin/wireshark
187 wireshark_home_t
190 - Set files with the wireshark_home_t type, if you want to store wire‐
192 shark files in the users home directory.
193 wireshark_tmp_t
197 - Set files with the wireshark_tmp_t type, if you want to store wire‐
199 shark temporary files in the /tmp directories.
200 wireshark_tmpfs_t
204 - Set files with the wireshark_tmpfs_t type, if you want to store wire‐
206 shark files on a tmpfs file system.
207 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
217 semanage fcontext can also be used to manipulate default file context
218 mappings.
219 semanage permissive can also be used to manipulate whether or not a
221 process type is permissive.
222 semanage module can also be used to enable/disable/install/remove pol‐
224 icy modules.
225 semanage boolean can also be used to manipulate the booleans
227 system-config-selinux is a GUI tool available to customize SELinux pol‐
230 icy settings.
