Protocol Analyzer: Top 6 Network Protocol Analyzer Tools 2023

Explore some top Network Protocol Analyzer Tools and select the best Protocol Analyzer to evaluate the network performance:

In this tutorial, we will explore the protocol analyzer and its various uses of it. Also, we will find out some of the major tools deployed in the industry to capture and analyze the network trends and other parameters by the different protocol analyzers tools.

A protocol analyzer is commonly known as a network analyzer because it can be inserted into the network to monitor and capture live activities and to safeguard the network and its entities against malicious attacks.

Thus, it can perform this by inserting the tool into the network uplink, and at the same instance time, the tool can perform the activity for multiple devices and network channels.

The Placement of the network analyzer into the communication channel or just into the network primarily depends upon the business requirements of the network and owners.

Network Protocol Analyzer and Tools

For example, the Wire shark tool can be inserted into the network channel, such as it can be part of the firewall to detect and report spam. On the other hand, it can also run as a web-interface-based tool to monitor, capture, and troubleshoot the network elements.

What is a Protocol Analyzer

A protocol analyzer is a combination of hardware and software systems in which the hardware part is responsible for capturing and analyzing the data of the network or the communication channel and the software part is responsible to display that captured output in a form that can be readable by the end-user.

The protocol analyzer gives an insight view of various network protocols like USB, I2C, CAN, etc. through which the data travels via the communication link.

Thus, the protocol analyzer helps the engineers to debug the errors, monitor the product performance, traffic of the data link in the embedded systems throughout the life span of the development of the software or hardware product.

Use of Protocol Analyzer or Network Analyzer

  • One of the major uses is to evaluate the network performance and provide protection to the network against mischievous activity within an organization. This is done by collecting the data packets and recording them which are traveling on the network.
  • It can be used for a particular device or many devices simultaneously on the same network.
  • It locates the parts of the network which are causing congestion in the network traffic flow.
  • It identifies the abnormal packet characteristics in the network and over the Internet.
  • Itself configures the alarm and alerts pop-ups for the threats.
  • Create GUI friendly end-user web portal for downloading and extracting the outcomes of the analysis.
  • Continuous monitor and locate the real-time network malware attacks.
  • It debugs the network protocol’s various implementations.
  • The active network devices that protocol analyzer tests are oscillators, transceivers, tuners, receivers, modulators, etc.
  • The passive network devices that protocol analyzer tests are routers, bridges, isolators, resonators, duplexers, filters, splitters, adapters, RLC’s, etc.

Types of Protocol Analyzers

  • We have different kinds of protocol analyzers. One is an unfiltered packet sniffer. It can encapsulate all raw packets flowing into the network and the Internet and copy the outcome into the local drive on the host computer for later analysis. The wired networks generally practice it and they keep the results secure for later analysis.
  • Another one is a filtered, packet sniffer. It is designed in such a way that it will capture only a few data packets flowing in the network for which it is intended. In this way, the protocol analyzer will smartly collect the packets of its users only and can perform the analysis easily.
  • The wireless networks deploy the filtered kind of packet sniffers into their network so that can get the outputs over a wider range of interfaces at the same instance of time.
  • Even though the network analyzers are a combination of both the software and hardware part, we can categorize them as the hardware protocol analyzer and software protocol analyzer.
  • The first one, encapsulating and analyzing the packets at different interfaces of the network thus commonly known as protocol analyzers. They are deployed to debug the hardware and complicated interfaces of the network.
  • Later, one uses only the software to capture the data packets and work on the software level only. Mostly used for the wireless network over LAN and WAN connections to analyze the different patterns. Thus, commonly known as network analyzers.

Advantages of Using Protocol Analyzers

These include:

  • It helps in minimizing the debugging time. We can capture the complex data packets easily and can analyze them with minimal delay. Overall, improve the network performance and cut down the debug time to more than half.
  • Deploying protocol analyzers in the network has completely ruled out the manual network error capture and analysis procedure. This minimal the human error possibilities and delay factor in capturing the data packets and processing.
  • It offers live capturing and can work simultaneously on many networks with a large number of network elements. The automation process has added more value to the process of encountering and eliminating the malicious threat in the network.
  • It can perform the operations for a wider range of interfaces and some complex network protocols, also like PCIe.
  • By using a packet sniffer, we can track which sites the end-user is exploring more over the Internet. Along with this, we can monitor the kind of downloaded files by the end-user. This feature helps the organizations to keep a record of employees’ browsing history and upgrade their security features accordingly.

Risk Factors

Enlisted below are risk factors:

  • Sometimes in corporate networks, due to the mistake of the employee, the user downloaded spam e-mails into their inbox, which gives the unauthorized packet sniffer access to the corporate network. Thus the hackers can use the confidential data for personal benefit and damage the network.
  • Also, the personal data of the employee of any organization is get compromised as the system administrator will check out and monitor all the incoming traffic and browsing patterns of the user.

Frequently Asked Questions

Q #1) What are protocols?

Answer: In context with computer networking, it is a combination of rules for designing and developing data. It is the language that the computer understands. By use of these protocols, the various computers can communicate with each other without being connected physically.

Q #2) Is packet sniffer and protocol analyzer are same?

Answer: Yes, both are the same. A sniffer analyzes the data packets that stream between the network components within a network or over the Internet.

Q #3) How protocol analyzers will detect malicious attacks?

Answer: It generates different set pattern packets when they encounter viruses. Then generate the alert to the system and it will report the administrator through the mail or alert message regarding the virus activity.

Q #4) How do the hackers use sniffers?

Answer: They can use sniffers by inducing their packet into the network immorally and then can get access to confidential data such as passwords and network traffic trends.
