dSniff is a set of password sniffing and network traffic analysis tools written by security researcher and startup founder Dug Song to parse different application protocols and extract relevant information. dsniff, filesnarf, mailsnarf, msgsnarf, urlsnarf, and webspy passively monitor a network for interesting data (passwords, e-mail, files, etc.). arpspoof, dnsspoof, and macof facilitate the ...
Sniffing attack in context of network security, corresponds to theft or interception of data by capturing the network traffic using a packet sniffer (an application aimed at capturing network packets). When data is transmitted across networks, if the data packets are not encrypted, the data within the network packet can be read using a sniffer. [1]
Using packet capture and storage, telecommunications carriers can provide the legally required secure and separate access to targeted network traffic and can use the same device for internal security purposes. Collecting data from a carrier system without a warrant is illegal due to laws about interception.
In this model, a string is given to actual users, and to connect with another user, strings have to be exchanged and have to match. [7] If another user tries to invade the system, the string will not match, and Cfones blocks attackers from entering the network. [7] This model is specific to preventing man-in-the-middle attacks.

The technology traces its roots back over 30 years, when many of the pioneers contributed their inventions for use among industry participants, such as through common standards and early innovation, such as the following: RMON; Sniffer; Wireshark; Essential DPI functionality includes analysis of packet headers and protocol fields.
Illustration of a replay attack. Alice (A) sends her hashed password to Bob (B). Eve (E) sniffs the hash and replays it. Suppose Alice wants to prove her identity to Bob. . Bob requests her password as proof of identity, which Alice dutifully provides (possibly after some transformation like hashing, or even salting, the password); meanwhile, Eve is eavesdropping on the conversation and keeps ...
Brute-force attacks work by calculating every possible combination that could make up a password and testing it to see if it is the correct password. As the password's length increases, the amount of time, on average, to find the correct password increases exponentially. [6]
