6 ntop_selinux - Security Enhanced Linux Policy for the ntop processes
7
9 Security-Enhanced Linux secures the ntop processes via flexible manda‐
10 tory access control.
11
12 The ntop processes execute with the ntop_t SELinux type. You can check
13 if you have these processes running by executing the ps command with
14 the -Z qualifier.
15
16 For example:
17
18 ps -eZ | grep ntop_t
19
20
21
23 The ntop_t SELinux type can be entered via the ntop_exec_t file type.
24
25 The default entrypoint paths for the ntop_t domain are the following:
26
27 /usr/sbin/ntop
28
30 SELinux defines process types (domains) for each process running on the
31 system
32
33 You can see the context of a process using the -Z option to ps
34
35 Policy governs the access confined processes have to files. SELinux
36 ntop policy is very flexible allowing users to setup their ntop pro‐
37 cesses in as secure a method as possible.
38
39 The following process types are defined for ntop:
40
41 ntop_t
42
43 Note: semanage permissive -a ntop_t can be used to make the process
44 type ntop_t permissive. SELinux does not deny access to permissive
45 process types, but the AVC (SELinux denials) messages are still gener‐
46 ated.
47
48
50 SELinux policy is customizable based on least access required. ntop
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run ntop with the tightest access possible.

167 SELinux defines port types to represent TCP and UDP ports.
168
169 You can see the types associated with a port by using the following
170 command:
171
172 semanage port -l
173
174
175 Policy governs the access confined processes have to these ports.
176 SELinux ntop policy is very flexible allowing users to setup their ntop
177 processes in as secure a method as possible.
178
179 The following port types are defined for ntop:
180
181
182 ntop_port_t
183
184
185
186 Default Defined Ports:
187 tcp 3000-3001
188 udp 3000-3001
189
191 The SELinux process type ntop_t can manage files labeled with the fol‐
192 lowing file types. The paths listed are the default paths for these
193 file types. Note the processes UID still need to have DAC permissions.

243 SELinux requires files to have an extended attribute to define the file
244 type.
245
246 You can see the context of a file using the -Z option to ls
247
248 Policy governs the access confined processes have to these files.
249 SELinux ntop policy is very flexible allowing users to setup their ntop
250 processes in as secure a method as possible.
251
252 STANDARD FILE CONTEXT
253
254 SELinux defines the file context types for the ntop, if you wanted to
255 store files with these types in a diffent paths, you need to execute
256 the semanage command to sepecify alternate labeling and then use
257 restorecon to put the labels on disk.
258
259 semanage fcontext -a -t ntop_var_run_t '/srv/myntop_content(/.*)?'
260 restorecon -R -v /srv/myntop_content
261
262 Note: SELinux often uses regular expressions to specify labels that
263 match multiple files.
264
265 The following file types are defined for ntop:
266
267
268
269 ntop_etc_t
270
271 - Set files with the ntop_etc_t type, if you want to store ntop files
272 in the /etc directories.
273
274
275
276 ntop_exec_t
277
278 - Set files with the ntop_exec_t type, if you want to transition an
279 executable to the ntop_t domain.
280
281
282
283 ntop_initrc_exec_t
284
285 - Set files with the ntop_initrc_exec_t type, if you want to transition
286 an executable to the ntop_initrc_t domain.
287
288
289
290 ntop_tmp_t
291
292 - Set files with the ntop_tmp_t type, if you want to store ntop tempo‐
293 rary files in the /tmp directories.
294
295
296
297 ntop_var_lib_t
298
299 - Set files with the ntop_var_lib_t type, if you want to store the ntop
300 files under the /var/lib directory.
301
302
303
304 ntop_var_run_t
305
306 - Set files with the ntop_var_run_t type, if you want to store the ntop
307 files under the /run or /var/run directory.
308
309
310
311 Note: File context can be temporarily modified with the chcon command.
312 If you want to permanently change the file context you need to use the
313 semanage fcontext command. This will modify the SELinux labeling data‐
314 base. You will need to use restorecon to apply the labels.
315
316
318 semanage fcontext can also be used to manipulate default file context
319 mappings.
320
321 semanage permissive can also be used to manipulate whether or not a
322 process type is permissive.
323
324 semanage module can also be used to enable/disable/install/remove pol‐
325 icy modules.
326
327 semanage port can also be used to manipulate the port definitions
328
329 semanage boolean can also be used to manipulate the booleans
330
331
332 system-config-selinux is a GUI tool available to customize SELinux pol‐
333 icy settings.
