CyTrONE Web UI: Web User Interface for CyTrONE

CyTrONE Web UI is a web browser user interface for the integrated cybersecurity training framework CyTrONE. The interface is intended for training instructors, who can use it to create new training sessions and to terminate existing ones. CyTrONE Web UI is being developed by the Cyber Range Organization and Design (CROND) NEC-endowed chair at the Japan Advanced Institute of Science and Technology (JAIST).

A screenshot of the web interface is shown in the figure below. In the left-hand side panel existing training content is displayed, and the Create Session button can be used to create a new training session (the number of requested cyber range instances should be set via the dialog box shown subsequently). The right-hand side panel displays the active training sessions, and can be used to terminate them via the End Session button. Both the training content and active sessions panels can be refreshed by clicking the corresponding buttons in case the data was updated externally (e.g., new content was added to CyTrONE while the UI was running).

Next we provide brief information on how to setup and use CyTrONE Web UI. For more details, please refer to the User Guide made available in the v0.3 release.

Prerequisites

CyTrONE Web UI has been developed using the Perl programming language on Ubuntu 18.04 LTS, so installing Perl is required if it is not installed already. To do that, run the following command:

$ sudo apt-get install perl

Then the necessary Perl modules need to be installed, for example by using the cpan command. The list of required Perl modules is as follows:

Net::WebSocket::Server
YAML::Tiny
URI::Escape
Digest::MD5
Data::Dump
LWP::Protocol::https

Setup

While there is no installation procedure for CyTrONE Web UI, changing its settings according to your environment is necessary. This is accomplished by creating a configuration file based on the sample provided in door.conf.dist. The settings included in this sample are explained below:

Configure the address and port on which the UI will listen for web browser connections; for example, to make possible connecting via http://192.168.1.1:8080, you should specify the following settings:
```
httpd_addr    192.168.1.1
httpd_port    8080
wsd_addr      192.168.1.1
```
Configure the user name and password for connecting to the web UI; for example, to make possible connecting via the user cy_user and password cy_passwd, you should specify the following settings:
```
httpd_userpasswd    cy_user cy_passwd
```
Note that the user name and password specified here are also used to authenticate with CyTrONE, so these values must match those set for the CyTrONE server.
Configure the settings used when the UI connects to the CyTrONE server; for example, to use the https protocol to connect locally (assuming the UI and CyTrONE are installed on the same host), and to retrieve English language content, use the following settings:
```
trngsrv_proto    https
trngsrv_host     127.0.0.1
trngsrv_lang     en
```

Depending on the configuration of the SSL server certificate for your CyTrONE server, such as in the case of using self-signed certificates, you may also need to disable the host name verification in the Perl SSL implementation via the following command:

$ export PERL_LWP_SSL_VERIFY_HOSTNAME=0

Quick Start

In order to start CyTrONE Web UI, run the command below (assuming that the configuration file you created above is named door.conf):

$ perl door.pl -f door.conf

The UI program can be stopped simply by entering Ctrl-C in the terminal where it was started.

All the available command-line options can be viewed using the argument -h when running the program:

$ perl door.pl -h

    -V          print parameters                ;

    -c dirs     HTTP document root directories  ; htmldoc
    -P port     WS service port number          ; 12345
    -A addr     WS service address              ; 127.0.0.1

    -D string   debug-masking of module,protocol;
    -q          quiet mode                      ; 0
    -m          trace messages intro syslog     ; 0
    -z          sleep until client access       ;

example:
    % door.pl -p 4989 -P 3213 -c docroot
    % door.pl -f door.conf
