Most network monitoring tools can’t provide all the information that network administrators, IT managers, security professionals, auditors, software developers, analysts and forensics investigator need to know. The only way to abundantly and absolutely know how your network is being used is to capture the data packets and analyze them in detail. Network consultants know the value of this information, even when it comes with a high manpower cost. They will run a packet sniffer like Wireshark and tcpdump to capture raw network traffic into disk files, and then inspect the data with programs like strings. This yields only a brief and confusing glimpse into traffic data and it is manually intensive and massively time-consuming.
NIT (Network Investigation Toolkit) is an integrated network monitoring and forensics analysis system, developed by Decision Group. NIT is delivered as a complete system with hardware (IBM X200 laptop and 3.5G/HSDPA USB Adapter for remote access by the user) and software pre-installed, ready to be placed in a machine room, NOC or any field deployment. To use NIT, an IT manager or forensics investigator simply connects the system to the mirror port switch at the internet gateway or work as a standalone system in the wireless environment for a real-time capturing of data and reconstruction. The operation quite similar to Intrusion Detection Systems (IDSs), but NIT performs more than what IDS has by reconstructing the raw data captured to the original content format in real time. Apart from both wired and wireless functionality, NIT also includes the integrated features of HTTPS/SSL MITM interception on both LAN and WLAN networks as well as offline analysis and reconstruction of pre-captured raw data files.
NIT is specially designed for law enforcement agencies, police & military intelligent, Criminal Investigation Agencies, National Security Agencies, Cyber Security Agencies, Counter Terrorism Department, Forensics Investigator etc. to conduct the network based forensics investigation be it on a Wired or Wireless LAN networks.

With the capability to scan all WLAN channels (802.11a/b/g – 2.4 GHz and 5 GHz frequency bands) to capture/sniff WLAN traffic from available Wi-Fi networks, decrypt WEP encrypted (WPA-PSK optional module) wireless network (automatically or manually), decode and reconstruct captured WLAN raw data, store the raw data captured and store the reconstructed data in its database, and display them in the original and exact content format, it make it the most complete (All-in-One) WLAN interception and forensic investigation tool. Furthermore, the Wireless-Detective user management interface or GUI (accessed through a browser) is very user friendly, easy to operate and manage.
Wireless-Detective is capable of decoding and reconstruct WLAN Internet traffic in real time such as Email (POP3, SMTP, IMAP), Webmail (Gmail, Yahoo Mail, Windows Live Hotmail etc.), Instant Messaging/Chat (MSN/Windows Live Messenger, Yahoo Messenger, IRC, ICQ, QQ, UT Chat Room, Google Talk Gmail, Skype Voice Log), FTP, P2P, Online Game, TELNET, HTTP (URL Link, Content, Reconstruct, Download/Upload, Video Stream) etc. After the decoding and reconstruction of the captured traffic, it displays them in its menu list according to different protocol/category types in exact or original content format. With capability of search by keyword or search by parameter (conditional search), it allows further forensics investigation and analysis to be carried out. This has proven that Wireless-Detective is an All-in-One system (all WLAN investigation work is conducted in one machine) that can speed up the entire investigation process.
Due to these advantages of Wireless-Detective system compare to other available wireless forensic tools, a lot of forensics professionals all over the world have opted to have Wireless-Detective system as their professional tool for legal interception and investigation. For these guys, the mobility (smallest system) of Wireless-Detective and its complete features/functions, reliability and All-in-One solution have won their heart and trust to fight Internet fraud, high tech criminal and terrorism through the usage of Wi-Fi networks.

EDDC - Offline Network Packet Reconstruction Tool
E-Detective Decoding Centre (EDDC) is designed as a Linux based centralized system for offline Internet raw data file parsing and reconstruction. It can be used to parser (decode and reconstruct) raw data files in PCAP format collected from different sources. Internet raw data (Internet packets) files can be collected from an Ethernet/LAN network or a WLAN network through different packet capturing or sniffing tools such as Ethereal, Wireshark, tcpdump, WinDump etc.
EDDC comes with specifically designed features that allow different forensic investigators to identify project or case specific offline Internet raw data files for decoding and reconstruction on a system. It allows the administrator to create different user accounts and different cases of investigation for various users or forensic professionals or investigators. The administrator has the flexibility to assign different rights and access levels to different users to manage access to the reconstructed data on different cases. The users can then import their Internet raw data files collected from different sources into the system to carry out the parser and analysing process.
EDDC allows Internet Content Forensics tasks to be carried out easily and systematically in order to obtain a variety of information and evidence needed from the Internet raw data files collected. EDDC also aims to assist Police Intelligence Services, Military Intelligence Organizations, Intelligence Bureaus, National Security Agencies, Government Intelligence Agencies and all forensics related agencies in conducting Internet Content Forensics geared towards enhancing their investigative effort.

Wireshark for Network Packet Analysis
Wireshark is a free packet sniffer and analyzer tool. It is commonly used for network troubleshooting, analysis, software and communications protocol development and education. Previously, it is known as Ethereal.
Wirehsark is very similar to tcpdum but it has a GUI and many more information sorting and filtering options. It provides user the capability to analyze network packets of various protocols in details.
Example 1: HTTP Client Web Access Packet Analysis Using Wireshark
Example 2: SMTP Email Acess Packet Analysis Using Wireshark
For a complete understanding and usage of Wireshark and other network packet analyzer and reconstruction tools, you may consider attending the Network Packet Forensics Analysis Training Course conducted by Decision Group. Click Here for more information.

Network Forensics Blog Borns!
Great! It is a wonderful night and this is a new blog that I have created. As my interest in on Digital Forensics (most appropriately Network Forensics), so I decided to create this blog to share my idea and knowledge with all of you.
What is Network Forensics?
Network Forensics involving the collection of network packets from Wired or Wireless Networks, analysing, recoverig the information from the packets back to the original content format and reporting themin presentable and forensics sound manner in the court of law. The network packets collected may contain different service categories cush as Email, Webmail, Instant Messaging, File Tranfer (FTP, P2P Sharing), HTTP Web Browsing, Telnet etc.
Stay tune! More to come!
