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 dontaudit all daemons scheduling requests (setsched,
71 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
72 Enabled by default.
73 setsebool -P daemons_dontaudit_scheduling 1
75 If you want to allow all domains to execute in fips_mode, you must turn
79 on the fips_mode boolean. Enabled by default.
80 setsebool -P fips_mode 1
82 If you want to allow system to run with NIS, you must turn on the
86 nis_enabled boolean. Disabled by default.
87 setsebool -P nis_enabled 1
89
93 SELinux defines port types to represent TCP and UDP ports.
94 You can see the types associated with a port by using the following
96 command:
97 semanage port -l
99 Policy governs the access confined processes have to these ports.
102 SELinux tor policy is very flexible allowing users to setup their tor
103 processes in as secure a method as possible.
104 The following port types are defined for tor:
106 tor_port_t
109 Default Defined Ports:
113 tcp 6969,9001,9030,9050,9051,9150
114
116 The SELinux process type tor_t can manage files labeled with the fol‐
117 lowing file types. The paths listed are the default paths for these
118 file types. Note the processes UID still need to have DAC permissions.

181 SELinux requires files to have an extended attribute to define the file
182 type.
183 You can see the context of a file using the -Z option to ls
185 Policy governs the access confined processes have to these files.
187 SELinux tor policy is very flexible allowing users to setup their tor
188 processes in as secure a method as possible.
189 EQUIVALENCE DIRECTORIES
191 tor policy stores data with multiple different file context types under
194 the /var/lib/tor directory. If you would like to store the data in a
195 different directory you can use the semanage command to create an
196 equivalence mapping. If you wanted to store this data under the /srv
197 directory you would execute the following command:
198 semanage fcontext -a -e /var/lib/tor /srv/tor
200 restorecon -R -v /srv/tor
201 STANDARD FILE CONTEXT
203 SELinux defines the file context types for the tor, if you wanted to
205 store files with these types in a different paths, you need to execute
206 the semanage command to specify alternate labeling and then use re‐
207 storecon to put the labels on disk.
208 semanage fcontext -a -t tor_exec_t '/srv/tor/content(/.*)?'
210 restorecon -R -v /srv/mytor_content
211 Note: SELinux often uses regular expressions to specify labels that
213 match multiple files.
214 The following file types are defined for tor:
216 tor_etc_t
220 - Set files with the tor_etc_t type, if you want to store tor files in
222 the /etc directories.
223 tor_exec_t
227 - Set files with the tor_exec_t type, if you want to transition an exe‐
229 cutable to the tor_t domain.
230 Paths:
233 /usr/bin/tor, /usr/sbin/tor
234 tor_initrc_exec_t
237 - Set files with the tor_initrc_exec_t type, if you want to transition
239 an executable to the tor_initrc_t domain.
240 tor_unit_file_t
244 - Set files with the tor_unit_file_t type, if you want to treat the
246 files as tor unit content.
247 tor_var_lib_t
251 - Set files with the tor_var_lib_t type, if you want to store the tor
253 files under the /var/lib directory.
254 Paths:
257 /var/lib/tor(/.*)?, /var/lib/tor-data(/.*)?
258 tor_var_log_t
261 - Set files with the tor_var_log_t type, if you want to treat the data
263 as tor var log data, usually stored under the /var/log directory.
264 tor_var_run_t
268 - Set files with the tor_var_run_t type, if you want to store the tor
270 files under the /run or /var/run directory.
271 Note: File context can be temporarily modified with the chcon command.
275 If you want to permanently change the file context you need to use the
276 semanage fcontext command. This will modify the SELinux labeling data‐
277 base. You will need to use restorecon to apply the labels.
278
281 semanage fcontext can also be used to manipulate default file context
282 mappings.
283 semanage permissive can also be used to manipulate whether or not a
285 process type is permissive.
286 semanage module can also be used to enable/disable/install/remove pol‐
288 icy modules.
289 semanage port can also be used to manipulate the port definitions
291 semanage boolean can also be used to manipulate the booleans
293 system-config-selinux is a GUI tool available to customize SELinux pol‐
296 icy settings.
