Examine WireShark, a well-used network-packet analyzer. For this discussion: Define a packet analyzer and describe its...

Network packet analyzer is also known as network sniffer its entire network wireless and wired and Catches all the packets in network

Electric sniffer is basically is not considered as a malicious software that can be used in various password sniffing techniques and password capturing techniques

Network packet analysis usually help in to identify the connection problems to make corrections if any package can be analyzed and data can be monitored transfer protocol can be analyzed and malicious data in network condition if and monitor

Sequence diagrams and IP conversations can be tracked and there are automatic Diagnostic tools to diagnose the network packets girls helps in traffic monitoring and traffic visualizing using data representation

Some of the famous packet sniffers and network analyzers are

solarwinds deep packet inspection and analysis tool

paessler packet capture tool

tcpdump

windump

WildPackets' EtherPeek

fiddler

networkminer

Advantages:

Network analyst tool helps to detect the threats and denial of service attacks and detect undetected Malware and unauthorized request and device access.

It helps to detect malicious activities in network traffic network packet analyzer also helps to be effective Firewall and intrusion detection system.

The unauthorized access of devices which might cause the transfer of various malicious contents and data.

Malicious practices:

The hacking properties of network traffic is very effective that are traffic packets can be captured and analyzed and can be interpreted.

Most of the images in data transfer or not encrypted and all the encrypted data can be seen by the network sniffer even this packet analysis helps to man-in-the-middle attack password sniffing and social engineering can be done using this packet analysis Where are data traffic can be captured from particular IP so that those data analyst for further attack King purposes it is like and social engineering.

Cautions to be taken to protect from the Network sniffing attacks:

Expertise people can use various firewalls, and Intrusion detection systems to secure the network.

Non expertise individuals can go for the antivirus for protection purposes.

The best way to protect is used in the high end encryption techniques.

Avoid connecting to public wifi. Use only trusted networks.

Perform scheduled scan in networks for malicious content.

Access the data in authorized manner.
