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.
53
54
55
56 If you want to allow users to resolve user passwd entries directly from
57 ldap rather then using a sssd server, you must turn on the authlo‐
58 gin_nsswitch_use_ldap boolean. Disabled by default.
59
60 setsebool -P authlogin_nsswitch_use_ldap 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 Enabled 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 confined applications to run with kerberos, you
80 must turn on the kerberos_enabled boolean. Disabled by default.
81
82 setsebool -P kerberos_enabled 1
83
84
85
86 If you want to allow system to run with NIS, you must turn on the
87 nis_enabled boolean. Disabled by default.
88
89 setsebool -P nis_enabled 1
90
91
92
93 If you want to allow confined applications to use nscd shared memory,
94 you must turn on the nscd_use_shm boolean. Disabled by default.
95
96 setsebool -P nscd_use_shm 1
97

101 SELinux defines port types to represent TCP and UDP ports.
102
103 You can see the types associated with a port by using the following
104 command:
105
106 semanage port -l
107
108
109 Policy governs the access confined processes have to these ports.
110 SELinux ntop policy is very flexible allowing users to setup their ntop
111 processes in as secure a method as possible.
112
113 The following port types are defined for ntop:
114
115
116 ntop_port_t
117
118
119
120 Default Defined Ports:
121 tcp 3000-3001
122 udp 3000-3001
123
125 The SELinux process type ntop_t can manage files labeled with the fol‐
126 lowing file types. The paths listed are the default paths for these
127 file types. Note the processes UID still need to have DAC permissions.

177 SELinux requires files to have an extended attribute to define the file
178 type.
179
180 You can see the context of a file using the -Z option to ls
181
182 Policy governs the access confined processes have to these files.
183 SELinux ntop policy is very flexible allowing users to setup their ntop
184 processes in as secure a method as possible.
185
186 STANDARD FILE CONTEXT
187
188 SELinux defines the file context types for the ntop, if you wanted to
189 store files with these types in a diffent paths, you need to execute
190 the semanage command to sepecify alternate labeling and then use
191 restorecon to put the labels on disk.
192
193 semanage fcontext -a -t ntop_var_run_t '/srv/myntop_content(/.*)?'
194 restorecon -R -v /srv/myntop_content
195
196 Note: SELinux often uses regular expressions to specify labels that
197 match multiple files.
198
199 The following file types are defined for ntop:
200
201
202
203 ntop_etc_t
204
205 - Set files with the ntop_etc_t type, if you want to store ntop files
206 in the /etc directories.
207
208
209
210 ntop_exec_t
211
212 - Set files with the ntop_exec_t type, if you want to transition an
213 executable to the ntop_t domain.
214
215
216
217 ntop_initrc_exec_t
218
219 - Set files with the ntop_initrc_exec_t type, if you want to transition
220 an executable to the ntop_initrc_t domain.
221
222
223
224 ntop_tmp_t
225
226 - Set files with the ntop_tmp_t type, if you want to store ntop tempo‐
227 rary files in the /tmp directories.
228
229
230
231 ntop_var_lib_t
232
233 - Set files with the ntop_var_lib_t type, if you want to store the ntop
234 files under the /var/lib directory.
235
236
237
238 ntop_var_run_t
239
240 - Set files with the ntop_var_run_t type, if you want to store the ntop
241 files under the /run or /var/run directory.
242
243
244
245 Note: File context can be temporarily modified with the chcon command.
246 If you want to permanently change the file context you need to use the
247 semanage fcontext command. This will modify the SELinux labeling data‐
248 base. You will need to use restorecon to apply the labels.
249
250
252 semanage fcontext can also be used to manipulate default file context
253 mappings.
254
255 semanage permissive can also be used to manipulate whether or not a
256 process type is permissive.
257
258 semanage module can also be used to enable/disable/install/remove pol‐
259 icy modules.
260
261 semanage port can also be used to manipulate the port definitions
262
263 semanage boolean can also be used to manipulate the booleans
264
265
266 system-config-selinux is a GUI tool available to customize SELinux pol‐
267 icy settings.
