What is WiFi Packet Sniffer?

Wi-Fi Packet Sniffer is a hardware or software that can log or intercept the traffic between two systems. It is also called a Packet Analyzer or Protocol Analyzer.

What are the Packet Sniffing Best Practices?

Here are some best practices for Packet Sniffing:

• Knowing the Basics: Helps you to analyze network traffic.You need to know basic networking works. Moreover, knowing about the types of network traffic on a healthy network, like Address Resolution Protocol (ARP), Dynamic Host Configuration Protocol (DHCP), for network management, is key.You should also know what you want from the packet sniffer to collect and have at least a general idea of what is a normal condition and what is not.
• Copy Conservatively: A Wi-Fi packet sniffers will copy the payload of all packets traveling on the network. It helps you to protect your company and avoid putting sensitive information.
• Monitor Storage Space: Even if you just capturing packet headers or storing all the packets which can consume a large amount of your disk space. It is best to copy every tenth packet rather than copying every single one. This is known as packet sampling, and it is a practice used to characterize network traffic.
• Decode the Data: You need to select a packet LAN sniffer which is able to decode this administrative information and extract other valuable insights. Like varying port numbers between two packet travel.

What are the types of Packet Spoofing Attacks?

Here are some important types of Spoofing:

• IP Address Spoofing: It occurs at the network level.
• Address Resolution Protocol (ARP) Spoofing: It always happens at the data link layer.
• Domain Name System (DNS) Spoofing: Helps you turn away Internet traffic from legitimate servers to fake servers.
• Email Spoofing: While IP sniffing has been a cybersecurity threat, the Covid environment has built new opportunities for carrying email spoofing. In email spoofing, a link is given in the email which users click but they do not receive the expected information.

How does a Packet Analyzer work?

Packet sniffer copies data as it travels across a network and makes it available for viewing. The sniffing device copies all of the data that passes over a network.

Mostly, the packets of data that are reaped from the network get copied to a file. However, packet sniffers can collect lots of data, which includes encoded admin team information. You should find an analysis tool that helps you be dereferencing information on the journey of the packets and other pieces of information. Like the relevance of the port numbers that the packets travel between.

A straightforward Wi-Fi packet sniffer will copy all the packets traveling on the cisco network. This can be a serious problem if the packet contents are not required by network performance analysis.

So, to track the cisco network usage for 24 hours or over a few days, storing every packet will occupy a large amount of disk space. Therefore, it is good to sample and copy every 10th or 20th packet instead of copying over every single one.

Why do you need to use a WiFi Analyzer App?

A WiFi analyzer allows a visual display of the network data near your surrounding channels. This app turns your computer or mobile device into an analytics tool that helps you to identify what you do you require to optimize your network.

For example, with a Wi-Fi analyzer app, you can look for other channels on your Wi-Fi sniffer network. This helps you to identify if they are faster than your current system or not.

What is full packet capture?

Full packet capture copies all packets stored in a file with the .pcap extension. Businesses often do not like network professionals to use such a method because the packet contents may not be encrypted.

Allowing the use of full packet capture capabilities may break the confidentiality of data held by the enterprise and data security standards compliance.
