Network Sniffer – Network Sniffing Software

Deep Packet Inspection, or just Packet Analysis, uses network packet sniffing to quickly and accurately identify network and application reliability and performance. A network sniffer captures (makes a copy of) the packet data passing through the network. It then analyzes and presents the data to network engineers, system administrators, or anyone who needs a view of traffic passing through their network.

With network sniffing, users can identify the types and volumes of application traffic based on host IP addresses, ports, and protocols in use. This provides a wealth of information that can be very useful to engineers and administrators.

Information from network sniffing includes:

• Network Response Time (NRT) – three way handshake
• Application Response Time – Time to First Byte
• Traffic Distribution Analysis – traffic type, volume, and classification (business vs. non-business)

The network sniffer within SolarWinds Network Performance Monitor (NPM) provides a Quality of Experience dashboard that features a quick-glance summary of a variety of network and application performance metrics for all of the configured applications being monitored by network sniffing sensors.

Network Sniffer & Packet Sniffer

Network Sniffer is a tool that can help you locate network problems by allowing you to capture and view the packet level data on your network.

The Colasoft Capsa Network Sniffer is a powerful network analysis tool. It consists of a well-integrated set of functions that can resolve network problems. Colasoft's Network Sniffer can list all of the network packets in real-time from multi-network card (Include Modem, ISDN, ADSL) and can also support capturing packets based on the applications (SOCKET, TDI etc.). You can capture and observe all traffic of the application which is a potential issue. The Colasoft Capsa Network Sniffer GUI eliminates the learning curve and makes it easy to understand and simple to use. The Capsa Network Sniffer has several plug-ins for different protocols such as ETHERNET, IP, TCP, UDP, PPPOE, HTTP, FTP, WINS, PPP, SMTP, POP3 and so on.

The work "Sniffer" is a registered trademark of Network Associates, Inc. used on their network analyzing products. Colasoft has spent over 10 years refining it's Capsa Packet Analyzer and sniffer winning awards as an industry leading packet capture and analysis application.

Today, sniffer has become a special name of network monitor and analyzers; it also refers to the collecting of packet level data and information. ISS defines sniffer as: Sniffer is a tool which utilizes network interfaces of computer to capture data packets which destination is other computers.

Typical use of network sniffer is to analyze network traffic and bandwidth utilization, so that underlying troubles in the network can be identified. There are, however, two directional usages of sniffer which have coexisted since it was first produced:

Positive usage

Positive usage of a sniffer is also its regular usage, which has as its objective the desire to maintain the network and keep it working normally.

1. Capturing packets;
2. Recording and analyzing traffic;
3. Decrypting packets and displaying in clear text;
4. Converting data to readable format;
5. Showing relevant information like IP, protocol, host or server name and so on.

Not all packet sniffing softwares product have the same functions; some sniffers can analyze hundreds of protocols whereas others can only deal with one or two. The most common protocols analyzed by sniffer are TCP/IP, IPX, DECNet-Ordinarily, a sniffer is used as assistant tool of the network engineer for monitoring and analyzing a network, detecting intrusion, controlling traffic or supervising network activity. IT should be noted that such features may also be utilized by hackers as a snooping tool to break into other computers.

Negative usage

Negative usage of a sniffer is well known as its harms to network security:

1. Catching password, which is the main reason for most illegal uses of sniffing tool;
2. Capturing special and private information of transactions, like username, credit ID, account, and password;
3. Recording email or instant message and resuming its content;
4. Some Sniffers can even modify target the computer's information and damage the system;
5. Interupting the security of a network or to gain higher level authority.

With more and more hackers using of packet sniffers, it has become one of the most important tools in the defense of cyber-attacks and cyber-crime.

To understand how a sniffer works, we need to know the main components of a sniffer and its working principles.

1. Components

Sniffer is a combination of hardware and software. Different sniffers may have various configurations on account of designation and final usage, but basically, a sniffer is composed of four parts:

• Hardware

Most sniffing products can work with standard adapters. Some sniffers only support Ethernet or wireless adapters whereas others support multi-adapters and allow customization. If you plan to install a sniffer on your computer, you shall be sure what type of adapter you have and what type of adapter the sniffer requires.
