NAME

6       ntop_selinux - Security Enhanced Linux Policy for the ntop processes
7

DESCRIPTION

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

ENTRYPOINTS

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

PROCESS TYPES

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

BOOLEANS

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
54
55
56       If you want to dontaudit all  daemons  scheduling  requests  (setsched,
57       sys_nice),  you  must turn on the daemons_dontaudit_scheduling boolean.
58       Enabled by default.
59
60       setsebool -P daemons_dontaudit_scheduling 1
61
62
63
64       If you want to deny all system processes and Linux users to  use  blue‐
65       tooth wireless technology, you must turn on the deny_bluetooth boolean.
66       Disabled by default.
67
68       setsebool -P deny_bluetooth 1
69
70
71
72       If you want to allow all domains to execute in fips_mode, you must turn
73       on the fips_mode boolean. Enabled by default.
74
75       setsebool -P fips_mode 1
76
77
78
79       If  you  want  to  allow  system  to run with NIS, you must turn on the
80       nis_enabled boolean. Disabled by default.
81
82       setsebool -P nis_enabled 1
83
84
85

PORT TYPES

87       SELinux defines port types to represent TCP and UDP ports.
88
89       You can see the types associated with a port  by  using  the  following
90       command:
91
92       semanage port -l
93
94
95       Policy  governs  the  access  confined  processes  have to these ports.
96       SELinux ntop policy is very flexible allowing users to setup their ntop
97       processes in as secure a method as possible.
98
99       The following port types are defined for ntop:
100
101
102       ntop_port_t
103
104
105
106       Default Defined Ports:
107                 tcp 3000-3001
108                 udp 3000-3001
109

MANAGED FILES

111       The  SELinux process type ntop_t can manage files labeled with the fol‐
112       lowing file types.  The paths listed are the default  paths  for  these
113       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

178       SELinux requires files to have an extended attribute to define the file
179       type.
180
181       You can see the context of a file using the -Z option to ls
182
183       Policy governs the access  confined  processes  have  to  these  files.
184       SELinux ntop policy is very flexible allowing users to setup their ntop
185       processes in as secure a method as possible.
186
187       STANDARD FILE CONTEXT
188
189       SELinux defines the file context types for the ntop, if you  wanted  to
190       store  files with these types in a different 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
194       semanage fcontext -a -t ntop_exec_t '/srv/ntop/content(/.*)?'
195       restorecon -R -v /srv/myntop_content
196
197       Note:  SELinux  often  uses  regular expressions to specify labels that
198       match multiple files.
199
200       The following file types are defined for ntop:
201
202
203
204       ntop_etc_t
205
206       - Set files with the ntop_etc_t type, if you want to store  ntop  files
207       in the /etc directories.
208
209
210
211       ntop_exec_t
212
213       - Set files with the ntop_exec_t type, if you want to transition an ex‐
214       ecutable to the ntop_t domain.
215
216
217
218       ntop_initrc_exec_t
219
220       - Set files with the ntop_initrc_exec_t type, if you want to transition
221       an executable to the ntop_initrc_t domain.
222
223
224
225       ntop_tmp_t
226
227       -  Set files with the ntop_tmp_t type, if you want to store ntop tempo‐
228       rary files in the /tmp directories.
229
230
231
232       ntop_var_lib_t
233
234       - Set files with the ntop_var_lib_t type, if you want to store the ntop
235       files under the /var/lib directory.
236
237
238
239       ntop_var_run_t
240
241       - Set files with the ntop_var_run_t type, if you want to store the ntop
242       files under the /run or /var/run directory.
243
244
245
246       Note: File context can be temporarily modified with the chcon  command.
247       If  you want to permanently change the file context you need to use the
248       semanage fcontext command.  This will modify the SELinux labeling data‐
249       base.  You will need to use restorecon to apply the labels.
250
251

COMMANDS

253       semanage  fcontext  can also be used to manipulate default file context
254       mappings.
255
256       semanage permissive can also be used to manipulate  whether  or  not  a
257       process type is permissive.
258
259       semanage  module can also be used to enable/disable/install/remove pol‐
260       icy modules.
261
262       semanage port can also be used to manipulate the port definitions
263
264       semanage boolean can also be used to manipulate the booleans
265
266
267       system-config-selinux is a GUI tool available to customize SELinux pol‐
268       icy settings.
