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/sbin/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 deny all system processes and Linux users to use blue‐
57 tooth wireless technology, you must turn on the deny_bluetooth boolean.
58 Enabled by default.
59 setsebool -P deny_bluetooth 1
61 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 setsebool -P fips_mode 1
68
72 SELinux defines port types to represent TCP and UDP ports.
73 You can see the types associated with a port by using the following
75 command:
76 semanage port -l
78 Policy governs the access confined processes have to these ports.
81 SELinux ntop policy is very flexible allowing users to setup their ntop
82 processes in as secure a method as possible.
83 The following port types are defined for ntop:
85 ntop_port_t
88 Default Defined Ports:
92 tcp 3000-3001
93 udp 3000-3001
94
96 The SELinux process type ntop_t can manage files labeled with the fol‐
97 lowing file types. The paths listed are the default paths for these
98 file types. Note the processes UID still need to have DAC permissions.

145 SELinux requires files to have an extended attribute to define the file
146 type.
147 You can see the context of a file using the -Z option to ls
149 Policy governs the access confined processes have to these files.
151 SELinux ntop policy is very flexible allowing users to setup their ntop
152 processes in as secure a method as possible.
153 STANDARD FILE CONTEXT
155 SELinux defines the file context types for the ntop, if you wanted to
157 store files with these types in a diffent paths, you need to execute
158 the semanage command to sepecify alternate labeling and then use
159 restorecon to put the labels on disk.
160 semanage fcontext -a -t ntop_var_run_t '/srv/myntop_content(/.*)?'
162 restorecon -R -v /srv/myntop_content
163 Note: SELinux often uses regular expressions to specify labels that
165 match multiple files.
166 The following file types are defined for ntop:
168 ntop_etc_t
172 - Set files with the ntop_etc_t type, if you want to store ntop files
174 in the /etc directories.
175 ntop_exec_t
179 - Set files with the ntop_exec_t type, if you want to transition an
181 executable to the ntop_t domain.
182 ntop_initrc_exec_t
186 - Set files with the ntop_initrc_exec_t type, if you want to transition
188 an executable to the ntop_initrc_t domain.
189 ntop_tmp_t
193 - Set files with the ntop_tmp_t type, if you want to store ntop tempo‐
195 rary files in the /tmp directories.
196 ntop_var_lib_t
200 - Set files with the ntop_var_lib_t type, if you want to store the ntop
202 files under the /var/lib directory.
203 ntop_var_run_t
207 - Set files with the ntop_var_run_t type, if you want to store the ntop
209 files under the /run or /var/run directory.
210 Note: File context can be temporarily modified with the chcon command.
214 If you want to permanently change the file context you need to use the
215 semanage fcontext command. This will modify the SELinux labeling data‐
216 base. You will need to use restorecon to apply the labels.
217
220 semanage fcontext can also be used to manipulate default file context
221 mappings.
222 semanage permissive can also be used to manipulate whether or not a
224 process type is permissive.
225 semanage module can also be used to enable/disable/install/remove pol‐
227 icy modules.
228 semanage port can also be used to manipulate the port definitions
230 semanage boolean can also be used to manipulate the booleans
232 system-config-selinux is a GUI tool available to customize SELinux pol‐
235 icy settings.
