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 allow all domains to execute in fips_mode, you must turn
65 on the fips_mode boolean. Enabled by default.
66
67 setsebool -P fips_mode 1
68
69
70
71 If you want to allow confined applications to run with kerberos, you
72 must turn on the kerberos_enabled boolean. Enabled by default.
73
74 setsebool -P kerberos_enabled 1
75
76
77
78 If you want to allow system to run with NIS, you must turn on the
79 nis_enabled boolean. Disabled by default.
80
81 setsebool -P nis_enabled 1
82
83
84
85 If you want to allow confined applications to use nscd shared memory,
86 you must turn on the nscd_use_shm boolean. Enabled by default.
87
88 setsebool -P nscd_use_shm 1
89

91
93 SELinux defines port types to represent TCP and UDP ports.
94
95 You can see the types associated with a port by using the following
96 command:
97
98 semanage port -l
99
100
101 Policy governs the access confined processes have to these ports.
102 SELinux ntop policy is very flexible allowing users to setup their ntop
103 processes in as secure a method as possible.
104
105 The following port types are defined for ntop:
106
107
108 ntop_port_t
109
110
111
112 Default Defined Ports:
113 tcp 3000-3001
114 udp 3000-3001
115
117 The SELinux process type ntop_t can manage files labeled with the fol‐
118 lowing file types. The paths listed are the default paths for these
119 file types. Note the processes UID still need to have DAC permissions.

169 SELinux requires files to have an extended attribute to define the file
170 type.
171
172 You can see the context of a file using the -Z option to ls
173
174 Policy governs the access confined processes have to these files.
175 SELinux ntop policy is very flexible allowing users to setup their ntop
176 processes in as secure a method as possible.
177
178 STANDARD FILE CONTEXT
179
180 SELinux defines the file context types for the ntop, if you wanted to
181 store files with these types in a diffent paths, you need to execute
182 the semanage command to sepecify alternate labeling and then use
183 restorecon to put the labels on disk.
184
185 semanage fcontext -a -t ntop_var_run_t '/srv/myntop_content(/.*)?'
186 restorecon -R -v /srv/myntop_content
187
188 Note: SELinux often uses regular expressions to specify labels that
189 match multiple files.
190
191 The following file types are defined for ntop:
192
193
194
195 ntop_etc_t
196
197 - Set files with the ntop_etc_t type, if you want to store ntop files
198 in the /etc directories.
199
200
201
202 ntop_exec_t
203
204 - Set files with the ntop_exec_t type, if you want to transition an
205 executable to the ntop_t domain.
206
207
208
209 ntop_initrc_exec_t
210
211 - Set files with the ntop_initrc_exec_t type, if you want to transition
212 an executable to the ntop_initrc_t domain.
213
214
215
216 ntop_tmp_t
217
218 - Set files with the ntop_tmp_t type, if you want to store ntop tempo‐
219 rary files in the /tmp directories.
220
221
222
223 ntop_var_lib_t
224
225 - Set files with the ntop_var_lib_t type, if you want to store the ntop
226 files under the /var/lib directory.
227
228
229
230 ntop_var_run_t
231
232 - Set files with the ntop_var_run_t type, if you want to store the ntop
233 files under the /run or /var/run directory.
234
235
236
237 Note: File context can be temporarily modified with the chcon command.
238 If you want to permanently change the file context you need to use the
239 semanage fcontext command. This will modify the SELinux labeling data‐
240 base. You will need to use restorecon to apply the labels.
241
242
244 semanage fcontext can also be used to manipulate default file context
245 mappings.
246
247 semanage permissive can also be used to manipulate whether or not a
248 process type is permissive.
249
250 semanage module can also be used to enable/disable/install/remove pol‐
251 icy modules.
252
253 semanage port can also be used to manipulate the port definitions
254
255 semanage boolean can also be used to manipulate the booleans
256
257
258 system-config-selinux is a GUI tool available to customize SELinux pol‐
259 icy settings.
