Introduction to Wireshark
Wireshark is a powerful network tool used for traffic analysis on any network. Wireshark is free software that is used primarily by any security professional or administrator. Since it is less expensive, it is used for real-life troubleshooting and attempts to resolve network-related debugging problems. Wireshark is mainly used to reduce network traffic related issues, latency issues and come to a conclusion to get the real root cause. This tool must be operated by a user who has knowledge of all network concepts.
Using Wireshark in various areas
Wireshark, a network analyzer, is used as a network analyzer to capture packets over a network connection such as the office Internet or home network. The only drive present on the ethernet network is known as a packet. Wireshark has primarily used the packet analyzer for important functions such as packet capture, display, and filtering. Therefore, Wireshark has many uses in various fields, be it network related or network security.
The following areas are available for Wireshark:
- Use by network security engineers
- Use by network engineers
- Use by Cyber Security Officials
- Use for network protocol analysis
- Use in terms of the Internet and its operation for transfer on other systems.
- Usage in terms of performance and viability of the network in an environment
- Use by system administrators
1. Use by network security engineers
Network security engineers are in continuous use with Wireshark in terms of a network, as each network treats packets as a single discrete unit for transmission. It also makes use of the Ethernet layer, as it is in the TCP / IP protocol stack for its main function and operation. Network security engineers constantly monitor the network to solve all security-related problems.
They try to check if there is any kind of tracking or spoofing activity going on over the network. There are certain malformed packets that exist within the network or that may have been created intentionally by intruders; So in that case, it is very necessary to apply the color coding technique. Still, you need to improvise in this situation as it does not provide real alerts to alarm as an alert.
2. Use by network engineers
Unlike network security engineers, whose primary concern is related to the security aspect of a network to control intrusion activities, network engineers primarily deal with the latency and troubleshooting aspects of the network using the Wireshark tool. This transfer is also related to some of the other ways of transferring packets from source to destination. Performance issues or any kind of network related troubleshooting in the TCP / IP stack or infrastructure works and uses Wireshark religiously.
3. Use by Cyber Security Officials
All major institutes or organizations related to cybersecurity rely heavily on this network analysis tool. It helps to verify cyber crimes and intrusion or tracking activities that are performed on the network and mislead the end user in a similar way to network security engineers.
Cybersecurity and network experts use this Wireshark as it has many security level protocols that work in the background to make all network analysis processing more reliable in terms of security and threat. Sometimes using Wireshark by Cybersecurity cannot provide adequate results to decrypt the cyber key as it does not fit well with decryption regarding encrypted traffic.
4. Use for network protocol analysis
Although Wireshark has some built-in protocols that are reliable and smart enough to perform most network tasks, if any network-related problems arise within the system, then troubleshooting the system with network protocols like TCP , UDP, ICMP and DHCP make the whole network more flexible and improved. Even in terms of bandwidth and latency, these protocols, in one way or another, make the most of it.
Wireshark also has the ability to provide network-related figures and graphs showing all the attributes and graphs related to performance and analysis. IPV4 packet spoofing is pretty easy when using Wireshark; therefore it is very important to note that the particular IP address that is captured is real or not. Both the system administrator, that is, the IT team and the network engineers, must have a deep understanding of networking concepts, as well as mastery of the Wireshark tool, as it will be a complement.
5. Use in terms of the Internet and its operation for transfer to other systems
Wireshark alone cannot support and absorb all the traffic from other systems; rather, in modern computers, it uses networks that also use a device like switches that can only detect the traffic between the remote system and the local system simultaneously. They communicate with each other with the set of protocols mentioned above.
6. Use in terms of performance and viability of the network in an environment
Wireshark provides a seamless overview of a network by using analysis and reporting tools or plug-ins as part of the software. It helps to determine the overall throughput and latency, which exists in the created network or is present in the original network where the packet transfer is explicitly carried out on and off the network.
7. Use by system administrators
System administrators as part of the network team in organizations also play an important link with network engineers to set up environments by organizing and synchronizing hardware and network with the leniency of Wireshark as obvious for network analysis of the environment afterwards. configuration. System administrators with network engineers can perform pair programming to solve problems caused so far.
The use of Wireshark is numerous, from its flexibility to its versatility in the aspect of network analysis. The tool detects each packet as part of a network and helps network professionals in various ways to easily address and fix relevant problems. Wireshark has many advantages for network security and cybersecurity professionals and at the same time increases its wave in all other network related domains.
