However, in the case of a sniffer, all traffic is shared when the sniffer software commands the Network Interface Card (NIC) to stop ignoring the traffic. The NIC is put into promiscuous mode, and it reads communications between computers within a particular segment. This allows the sniffer ...
A packet sniffer — also known as a packet analyzer, protocol analyzer or network analyzer — is a piece of hardware or software used to monitor network traffic. Sniffers work by examining streams of data packets that flow between computers on a network
IP address encryption: The main point of VPN usage is to hide the user's IP address. Protocol encryption: Neither cookies nor search history (or anything like that) should be left unencrypted. Indirect information like that can tell much about the user and make a VPN useless. ...
In the hands of authorized network administrators, a sniffer is employed to maintain the unimpeded flow of traffic through a network. Conversely, in the hands of a hacker, a sniffer may be used for unauthorized monitoring of the network. When spelled with an upper case “S,” the term “...
