Introduction
LevelOne Internet Content Inspector, ICI empowers your business security and operations teams
by providing granular data monitoring and precise packet and session reconstruction capabilities. The
solution is designed to combine process and technology into a single effective system for network
forensics. Business can for the first time embrace Web 2.0 and maintain complete visibility and
control, while significantly reducing total cost of ownership through device consolidation. ICI offers
real innovation by enabling unprecedented visibility and control of applications and content with no
performance degradation. It identify applications accurately - regardless of port, protocol, evasive
tactic or SSL encryption – and scan content to stop threats and prevent data leakage.
It intercepts, captures and reconstruct Internet activities such as Email (POP3, SMTP, IMAP),
Webmail Read and Sent (Yahoo Mail, Gmail, Windows Live Hotmail, Seednet etc.), Instant
Messaging or Chat (Yahoo, Windows Live Messenger or MSN, ICQ, AOL, QQ, UT Chat Room, IRC,
Gtalk, Skype Voice Call Duration Log), HTTP (URL Link, Content, Upload and Download, Video
Streaming), File Transfer (P2P File Sharing, FTP), Online Games, VoIP (Yahoo Messenger) and
Webcam (Yahoo Messenger and Windows Live Messenger - MSN), VoIP (RTP Voice Call) and
Telnet sessions. ICI system encourages efficiency, prevents company network resource from abuses
by employees, tracing culprits of information and confidential data leakage, and monitors activities
and online behaviour of employees.
Ethernet LAN interception is an important approach to gather information of communications and
digital evidence. Ethernet LAN interception solutions capture all the traffic on the LAN network and
monitor the Internet activities. It is capable of live intercepting with real time capturing and
decoding/reconstruction, category classifying, behaviour analysing, data mining, reporting with
statistics etc.
ICI comes with wide variety of management and administrative functions. It provides you various
types of report with Top-Down View. Reports that can be created include Total Throughput Statistical
Report, Network Service Report (Daily, Weekly basis), Top Websites etc. All statistics can be
displayed in per IP Address or per User Account basis.
ICI also provides varieties of search functions. It provides Free Text Search (search by Key Words
with Boolean support), Conditional Search, Similar Search and Association with Relationship Search.
It also comes with Alert and Notification (Throughput, Conditional and Key Words Alert) functions that
allow the network Administrator to setup different alert rules and parameters. This allows alert to be
triggered (email to be sent to Administrator) once the specified content is found in the captured and
reconstructed content.

Backup function allows user to back up the captured raw data files or reconstructed contents. User
can setup auto backup to backup these files to external drive (NAS or SAN) through FTP upload
method. Besides, user can opt for manually backup these files by burning them into CD/DVD or even
downloaded them to a local hard drive/PC.
Other functions available are like Bookmark, Capture File List (Comparing the content of two files),
Online IP List, Authority Assignment, Syslog Server etc. Others functions include hashed export
(backup), file content comparison etc.
Who Need the ICI System
•Financial, Banking and Investment Organisations where all Internet transactions and
communications need to be archived (Record Keeping).
•Marketing organizations, design house, high technology and R&D firms where critical
confidential information need protected.
•Schools, colleges, institutions and universities that would like to monitor students and staffs
online activities and behaviour.
•Government agencies and ministries such as Police Intelligence, Military Intelligence, Secret
Service Agencies, National Security Agencies, Criminal Investigation Agencies, Counter
Terrorism Agencies etc.
•Any company or organization that wants to monitor, backup and archive their daily Internet
transaction and data.

Application and Implementation
The diagram below is a common ICI application and implementation diagram which can be applied to
any organization networks. ICI uses sniffer technology to sniff or capture network Internet packets
through a port-mirroring capable switch (normally a smart switch or layer 2/3 switch; a HUB can be
used too as HUB broadcast traffic to all ports). It then parses (decodes and reconstructs) the captured
raw data packets, store them in system database and displays the reconstructed data with reports in
original and readable format in the Web GUI.
Ethernet LAN Organization Network Monitoring and Interception

ICI can also be implementation at network with huge volume of traffic throughput such as mass
interception and lawful interception at Telco or ISP networks. This implementation is normally for
lawful enforcement agencies (LEA) such as cyber security agencies, national security agencies,
criminal investigation bureau, police and military intelligence. Please contact LevelOne sales team for
more details

Requirement
In order to get the ICI to capture your network activities successfully, a Port-Mirroring feature on the
network Ethernet switch is must. User can monitor traffic from any source port to a target port for real-
time analysis. Attach the ICI to the target port and study the traffic crossing the source port in a
completely unobtrusive manner. Most the Web Smart and fully Managed Layer2 Ethernet switches
support the Port-Mirroring feature
Web Smart or Fully Managed Layer2/3 Switch with Port-Mirroring feature
For the best performance and keep disruption minimal, we introduce the Mirror mode implementation
only which provides the Real-time Reconstruction and keep disruption minimal at the same time. The
captured packets are saved in PCAP format
Installation
1. Connect the power cord to ICI power socket on the rear panel
2. Patch lead between Switch Mirror port and ICI Monitor port
3. Patch lead between Switch port (any available port) and ICI Management port

Getting Started
This chapter shows how to manage the ICI system via standard Web Browser over local network,
also a quick guide about each function button from menu bar, as well as the examples of feature-rich
of report feature.
Web Management Interface
1. Use Internet Explorer (IE) Web Browser to access ICI system web management site. ICI system
uses port 443 for secure web access. Please remember to key in https://x.x.x.x, for example
https://192.168.1.60 (which is the default login).
2. Before you use this system, please make sure you have Java applet installed. Read the
instruction on “Before You Use This System” at the login page.
3. Username: root & Password: 000000 (six zero)
4. Choose your preferred language [Traditional Chinese] or [English] and then click on the login

Main Page - Total Throughput Statistical Report
Total Throughput Statistical Report provides Daily, Weekly and Total Traffic statistic of different
Internet service categories for the organization network. It shows the total traffic amount usage by the
entire network as well as breaks them out into different service categories. Online User List will show
the List of users (IP Address and Account).
Mail Report allows Administrator to send different reports such as Total Throughput Statistical Report,
Online IP List etc. to the specific Email account immediately or either by hourly, daily, weekly or
monthly basis as shown below.

Example 1:
Click on the Email - POP3 Quantity of Daily Traffic, it will List down the entire POP3 Emails in the
database.

Example 2:
Click on the HTTP – HTTP Content weekly traffic throughput (KB), it will display the bar chart of the
HTTP Content traffic for the entire week (7 days). By clicking bar chat (specific day), it will lead you to
that day details content.

Example 3:
Click on the Daily Traffic – Summary Report, it will pop out Statistical Report List window and you can
select to click Throughput Statistical Report or Top N report. Click on the Top N, it will display the
User Daily Traffic Top N by Listing the top user IP with information such as Who is?, Throughput (KB)
and Statistical Report which includes Protocol Daily, Weekly and Summary Report.

Click on Who is ? This will display the user (IP) relationship with username, user login etc. Click on
Protocol, it will display all applications and throughput (KB) used by this user (IP).

Besides generating report by IP, Administrator can also generate report by Account basis.
