6 tethereal_selinux - Security Enhanced Linux Policy for the tethereal
7 processes
8
10 Security-Enhanced Linux secures the tethereal processes via flexible
11 mandatory access control.
12
13 The tethereal processes execute with the tethereal_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 tethereal_t
20
21
22
24 The tethereal_t SELinux type can be entered via the tethereal_exec_t
25 file type.
26
27 The default entrypoint paths for the tethereal_t domain are the follow‐
28 ing:
29
30 /usr/sbin/tethereal.*
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 tethereal policy is very flexible allowing users to setup their tethe‐
40 real processes in as secure a method as possible.
41
42 The following process types are defined for tethereal:
43
44 tethereal_t
45
46 Note: semanage permissive -a tethereal_t can be used to make the
47 process type tethereal_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. tethe‐
54 real policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run tethereal with the tightest access
56 possible.
57
58
59
60 If you want to allow all domains to use other domains file descriptors,
61 you must turn on the allow_domain_fd_use boolean. Enabled by default.
62
63 setsebool -P allow_domain_fd_use 1
64
65
66
67 If you want to allow sysadm to debug or ptrace all processes, you must
68 turn on the allow_ptrace boolean. Disabled by default.
69
70 setsebool -P allow_ptrace 1
71
72
73
74 If you want to allow all domains to have the kernel load modules, you
75 must turn on the domain_kernel_load_modules boolean. Disabled by
76 default.
77
78 setsebool -P domain_kernel_load_modules 1
79
80
81
82 If you want to allow all domains to execute in fips_mode, you must turn
83 on the fips_mode boolean. Enabled by default.
84
85 setsebool -P fips_mode 1
86
87
88
89 If you want to enable reading of urandom for all domains, you must turn
90 on the global_ssp boolean. Disabled by default.
91
92 setsebool -P global_ssp 1
93
94
95
97 The SELinux process type tethereal_t can manage files labeled with the
98 following file types. The paths listed are the default paths for these
99 file types. Note the processes UID still need to have DAC permissions.

132 SELinux requires files to have an extended attribute to define the file
133 type.
134
135 You can see the context of a file using the -Z option to ls
136
137 Policy governs the access confined processes have to these files.
138 SELinux tethereal policy is very flexible allowing users to setup their
139 tethereal processes in as secure a method as possible.
140
141 STANDARD FILE CONTEXT
142
143 SELinux defines the file context types for the tethereal, if you wanted
144 to store files with these types in a diffent paths, you need to execute
145 the semanage command to sepecify alternate labeling and then use
146 restorecon to put the labels on disk.
147
148 semanage fcontext -a -t tethereal_tmp_t '/srv/mytethereal_con‐
149 tent(/.*)?'
150 restorecon -R -v /srv/mytethereal_content
151
152 Note: SELinux often uses regular expressions to specify labels that
153 match multiple files.
154
155 The following file types are defined for tethereal:
156
157
158
159 tethereal_exec_t
160
161 - Set files with the tethereal_exec_t type, if you want to transition
162 an executable to the tethereal_t domain.
163
164
165
166 tethereal_tmp_t
167
168 - Set files with the tethereal_tmp_t type, if you want to store tethe‐
169 real temporary files in the /tmp directories.
170
171
172
173 Note: File context can be temporarily modified with the chcon command.
174 If you want to permanently change the file context you need to use the
175 semanage fcontext command. This will modify the SELinux labeling data‐
176 base. You will need to use restorecon to apply the labels.
177
178
180 semanage fcontext can also be used to manipulate default file context
181 mappings.
182
183 semanage permissive can also be used to manipulate whether or not a
184 process type is permissive.
185
186 semanage module can also be used to enable/disable/install/remove pol‐
187 icy modules.
188
189 semanage boolean can also be used to manipulate the booleans
190
191
192 system-config-selinux is a GUI tool available to customize SELinux pol‐
193 icy settings.
