Sometimes the performance of an organization’s network or computing system could be down due to undetected reasons. These reasons cannot be detected without monitoring the network system. To monitor and intercept network traffic logs, a monitoring tool needs to be deployed on the network system. But what can be deployed to intercept and log network traffic passing through the network system? Let’s find out:
What can be Deployed to Monitor and Intercept Network System?
To analyze and intercept the network traffic logs, packet sniffers can be deployed on a network system. Packet sniffers can detect and intercept the packet data transmitted through the network system. Also, it can be a helpful tool to detect rogues and illegal interceptions of a network system. Through packet sniffing, any type of unauthorized access could be detected.
For avoiding illegal and unauthorized interception of a network or computing system, the system admin needs to deploy a network sniffer. The network sniffer is a perfect tool to monitor the network traffic and resolve most of the issues of the network system.
What is a Network Sniffer?
To understand the concept of a network sniffer, you need to know about internet routing. Whenever you are browsing the internet, your shared contents (browsing log, sent or received emails, shared files) are distributed across the internet as small manageable packages that are known as data packets. Each data packet moves through the application layer, IP layer, and hardware layer of a network system.
Network sniffers are the tools that are used to capture and inspect data packets. The data transmission process of a network system is completed through data packets. These data packets contain information and data from one user to another. The attacker or the cybersecurity experts apply a packet sniffer on a network system to capture and inspect data packets.
Some sniffing tools are really helpful to intercept, catch, and inspect data packages transmitting through a network system. The IT and security expert can detect the cause of performance issues of a network system by intercepting and inspecting data packages of the network system through the sniffers. By using these tools, the IT and security experts resolve the poor performance issues of a network system and prevent these issues from reoccurring.
What are Sniffing Tools & How They Work?
Sniffing tools are the tools that are used to intercept, monitor, capture, and inspect the transmitting data packets of a network system. Tools like Wireshark, Tcpdump, Windump, Telerik Fiddler, Paessler, SolarWinds are used to monitor and intercept the network traffic of a network system.
The sniffing tool works by intercepting data traffic when it passes through the network system. These tools copy the intercepted data to a file, which is known as packet capturing. Whenever the sniffing tool is installed, the NIC (Network Interface Card) interferes between the device and the network. A packet sniffer can help the system admin to target new resources while expanding the system capacity, managing the bandwidth, increasing efficiencies, ensuring and enhancing security service, and improving the user experience. Also, the sniffers can be used to monitor network traffic and track network lags.
Frequently Asked Questions (FAQs)
Can Packet Sniffer Improve the Security of a Network System?
A packet sniffer analyzes the network traffic log by type. These types are based on the destination of server IP addresses, ports, related volumes of traffic, which empowers the system admin to detect illegal traffic. That enables the system admin to eliminate illegal traffic, which increases the security of a network system.
Is it Possible to Improve Bandwidth Through the Packet Sniffer?
Yes, monitoring the network system through the packet sniffers can help the admin to understand how the network bandwidth is being used and by whom. Also, the network sniffer can retrieve the client’s performance metrics, autonomous access points, and network controllers.
Why do Hackers or Cybercriminals Use Packet Sniffers?
The hackers and the cybercriminals use packet sniffers to collect passwords, eavesdrop on the packets, and steal data. Also, packet sniffers could be used to conduct MitM attacks through hackers and cyber-attackers. Though it could be disastrous for the user, the data packets can be saved by using end-to-end encryption on the network system.
The packet sniffing tools are mostly perfect to monitor and analyze the traffic of a network system. An admin can detect and eliminate illegal intruders on a system. Also, it could be helpful for resolving the poor performance issue of the network system. It is recommended to use end-to-end encryption to avoid MitM and packet sniffing attacks on a network. That’s all for today, have a great & shiny day.
