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/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 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 setsebool -P authlogin_nsswitch_use_ldap 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 confined applications to run with kerberos, you
76 must turn on the kerberos_enabled boolean. Enabled by default.
77 setsebool -P kerberos_enabled 1
79 If you want to allow system to run with NIS, you must turn on the
83 nis_enabled boolean. Disabled by default.
84 setsebool -P nis_enabled 1
86 If you want to allow confined applications to use nscd shared memory,
90 you must turn on the nscd_use_shm boolean. Enabled by default.
91 setsebool -P nscd_use_shm 1
93 If you want to allow regular users direct dri device access, you must
97 turn on the selinuxuser_direct_dri_enabled boolean. Enabled by default.
98 setsebool -P selinuxuser_direct_dri_enabled 1
100 If you want to allows clients to write to the X server shared memory
104 segments, you must turn on the xserver_clients_write_xshm boolean. Dis‐
105 abled by default.
106 setsebool -P xserver_clients_write_xshm 1
108
112 The SELinux process type wireshark_t can manage files labeled with the
113 following file types. The paths listed are the default paths for these
114 file types. Note the processes UID still need to have DAC permissions.
115 cifs_t
117 ecryptfs_t
120 /home/[^/]+/.Private(/.*)?
122 /home/[^/]+/.ecryptfs(/.*)?
123 fusefs_t
125 /var/run/user/[^/]*/gvfs
127 nfs_t
129 user_fonts_cache_t
132 /root/.fontconfig(/.*)?
134 /root/.fonts/auto(/.*)?
135 /root/.fonts.cache-.*
136 /home/[^/]+/.fontconfig(/.*)?
137 /home/[^/]+/.fonts/auto(/.*)?
138 /home/[^/]+/.fonts.cache-.*
139 user_home_t
141 /home/[^/]+/.+
143 wireshark_home_t
145 /home/[^/]+/.wireshark(/.*)?
147 wireshark_tmp_t
149 wireshark_tmpfs_t
152 xserver_tmpfs_t
155
159 SELinux requires files to have an extended attribute to define the file
160 type.
161 You can see the context of a file using the -Z option to ls
163 Policy governs the access confined processes have to these files.
165 SELinux wireshark policy is very flexible allowing users to setup their
166 wireshark processes in as secure a method as possible.
167 STANDARD FILE CONTEXT
169 SELinux defines the file context types for the wireshark, if you wanted
171 to store files with these types in a diffent paths, you need to execute
172 the semanage command to sepecify alternate labeling and then use
173 restorecon to put the labels on disk.
174 semanage fcontext -a -t wireshark_tmpfs_t '/srv/mywireshark_con‐
176 tent(/.*)?'
177 restorecon -R -v /srv/mywireshark_content
178 Note: SELinux often uses regular expressions to specify labels that
180 match multiple files.
181 The following file types are defined for wireshark:
183 wireshark_exec_t
187 - Set files with the wireshark_exec_t type, if you want to transition
189 an executable to the wireshark_t domain.
190 wireshark_home_t
194 - Set files with the wireshark_home_t type, if you want to store wire‐
196 shark files in the users home directory.
197 wireshark_tmp_t
201 - Set files with the wireshark_tmp_t type, if you want to store wire‐
203 shark temporary files in the /tmp directories.
204 wireshark_tmpfs_t
208 - Set files with the wireshark_tmpfs_t type, if you want to store wire‐
210 shark files on a tmpfs file system.
211 Note: File context can be temporarily modified with the chcon command.
215 If you want to permanently change the file context you need to use the
216 semanage fcontext command. This will modify the SELinux labeling data‐
217 base. You will need to use restorecon to apply the labels.
218
221 semanage fcontext can also be used to manipulate default file context
222 mappings.
223 semanage permissive can also be used to manipulate whether or not a
225 process type is permissive.
226 semanage module can also be used to enable/disable/install/remove pol‐
228 icy modules.
229 semanage boolean can also be used to manipulate the booleans
231 system-config-selinux is a GUI tool available to customize SELinux pol‐
234 icy settings.
