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 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 For example:
17 ps -eZ | grep ntop_t
19
23 The ntop_t SELinux type can be entered via the ntop_exec_t file type.
24 The default entrypoint paths for the ntop_t domain are the following:
26 /usr/bin/ntop
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 ntop policy is very flexible allowing users to setup their ntop pro‐
37 cesses in as secure a method as possible.
38 The following process types are defined for ntop:
40 ntop_t
42 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
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.
53 If you want to allow all daemons to write corefiles to /, you must turn
57 on the allow_daemons_dump_core boolean. Disabled by default.

144 setsebool -P nscd_use_shm 1

150 SELinux defines port types to represent TCP and UDP ports.
151 You can see the types associated with a port by using the following
153 command:
154 semanage port -l
156 Policy governs the access confined processes have to these ports.
159 SELinux ntop policy is very flexible allowing users to setup their ntop
160 processes in as secure a method as possible.
161 The following port types are defined for ntop:
163 ntop_port_t
166 Default Defined Ports:
170 tcp 3000,3001
171 udp 3000,3001
172
174 The SELinux process type ntop_t can manage files labeled with the fol‐
175 lowing file types. The paths listed are the default paths for these
176 file types. Note the processes UID still need to have DAC permissions.

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