6 tor_selinux - Security Enhanced Linux Policy for the tor processes
7
9 Security-Enhanced Linux secures the tor processes via flexible manda‐
10 tory access control.
11 The tor processes execute with the tor_t SELinux type. You can check if
13 you have these processes running by executing the ps command with the
14 -Z qualifier.
15 For example:
17 ps -eZ | grep tor_t
19
23 The tor_t SELinux type can be entered via the tor_exec_t file type.
24 The default entrypoint paths for the tor_t domain are the following:
26 /usr/bin/tor, /usr/sbin/tor
28
30 SELinux defines process types (domains) for each process running on the
31 system
32 You can see the context of a process using the -Z option to ps
34 Policy governs the access confined processes have to files. SELinux
36 tor policy is very flexible allowing users to setup their tor processes
37 in as secure a method as possible.
38 The following process types are defined for tor:
40 tor_t
42 Note: semanage permissive -a tor_t can be used to make the process type
44 tor_t permissive. SELinux does not deny access to permissive process
45 types, but the AVC (SELinux denials) messages are still generated.
46
49 SELinux policy is customizable based on least access required. tor
50 policy is extremely flexible and has several booleans that allow you to
51 manipulate the policy and run tor with the tightest access possible.
52 If you want to determine whether tor can bind tcp and udp sockets to
56 all unreserved ports, you must turn on the tor_bind_all_unre‐
57 served_ports boolean. Disabled by default.
58 setsebool -P tor_bind_all_unreserved_ports 1
60 If you want to allow tor to act as a relay, you must turn on the
64 tor_can_network_relay boolean. Disabled by default.
65 setsebool -P tor_can_network_relay 1
67 If you want to allow all domains to execute in fips_mode, you must turn
71 on the fips_mode boolean. Enabled by default.
72 setsebool -P fips_mode 1
74
78 SELinux defines port types to represent TCP and UDP ports.
79 You can see the types associated with a port by using the following
81 command:
82 semanage port -l
84 Policy governs the access confined processes have to these ports.
87 SELinux tor policy is very flexible allowing users to setup their tor
88 processes in as secure a method as possible.
89 The following port types are defined for tor:
91 tor_port_t
94 Default Defined Ports:
98 tcp 6969,9001,9030,9050,9051,9150
99
101 The SELinux process type tor_t can manage files labeled with the fol‐
102 lowing file types. The paths listed are the default paths for these
103 file types. Note the processes UID still need to have DAC permissions.

166 SELinux requires files to have an extended attribute to define the file
167 type.
168 You can see the context of a file using the -Z option to ls
170 Policy governs the access confined processes have to these files.
172 SELinux tor policy is very flexible allowing users to setup their tor
173 processes in as secure a method as possible.
174 EQUIVALENCE DIRECTORIES
176 tor policy stores data with multiple different file context types under
179 the /var/lib/tor directory. If you would like to store the data in a
180 different directory you can use the semanage command to create an
181 equivalence mapping. If you wanted to store this data under the /srv
182 directory you would execute the following command:
183 semanage fcontext -a -e /var/lib/tor /srv/tor
185 restorecon -R -v /srv/tor
186 STANDARD FILE CONTEXT
188 SELinux defines the file context types for the tor, if you wanted to
190 store files with these types in a diffent paths, you need to execute
191 the semanage command to specify alternate labeling and then use re‐
192 storecon to put the labels on disk.
193 semanage fcontext -a -t tor_unit_file_t '/srv/mytor_content(/.*)?'
195 restorecon -R -v /srv/mytor_content
196 Note: SELinux often uses regular expressions to specify labels that
198 match multiple files.
199 The following file types are defined for tor:
201 tor_etc_t
205 - Set files with the tor_etc_t type, if you want to store tor files in
207 the /etc directories.
208 tor_exec_t
212 - Set files with the tor_exec_t type, if you want to transition an exe‐
214 cutable to the tor_t domain.
215 Paths:
218 /usr/bin/tor, /usr/sbin/tor
219 tor_initrc_exec_t
222 - Set files with the tor_initrc_exec_t type, if you want to transition
224 an executable to the tor_initrc_t domain.
225 tor_unit_file_t
229 - Set files with the tor_unit_file_t type, if you want to treat the
231 files as tor unit content.
232 tor_var_lib_t
236 - Set files with the tor_var_lib_t type, if you want to store the tor
238 files under the /var/lib directory.
239 Paths:
242 /var/lib/tor(/.*)?, /var/lib/tor-data(/.*)?
243 tor_var_log_t
246 - Set files with the tor_var_log_t type, if you want to treat the data
248 as tor var log data, usually stored under the /var/log directory.
249 tor_var_run_t
253 - Set files with the tor_var_run_t type, if you want to store the tor
255 files under the /run or /var/run directory.
256 Note: File context can be temporarily modified with the chcon command.
260 If you want to permanently change the file context you need to use the
261 semanage fcontext command. This will modify the SELinux labeling data‐
262 base. You will need to use restorecon to apply the labels.
263
266 semanage fcontext can also be used to manipulate default file context
267 mappings.
268 semanage permissive can also be used to manipulate whether or not a
270 process type is permissive.
271 semanage module can also be used to enable/disable/install/remove pol‐
273 icy modules.
274 semanage port can also be used to manipulate the port definitions
276 semanage boolean can also be used to manipulate the booleans
278 system-config-selinux is a GUI tool available to customize SELinux pol‐
281 icy settings.
