For those who would like to look deep into their networks and not just on the outside, “Wireshark – the network protocol analyzer,” is the way to go! We will understand what is meant by “sniffing”, why it is used and how the Wireshark network protocol analyzer works in this post.
What are sniffers?
While social media rages on one side giving rise to new professions, there is another equally quiet but stealthy profession too – monitoring other people’s networks and activities by means of “sniffing”. Since a firewall cannot detect all malicious traffic we use “sniffers” to monitor the traffic across the network. As with everything else in security, “sniffers” can be used in a positive and negative way either by employers monitoring their employees or by scrupulous individuals trying to hack systems.
