What is Passive Online Attacks

A Passive online attack is also known as sniffing the password on a wired or wireless network.
Passive Online Attacks is not perceivable to the end client. The secret word is caught amid the confirmation procedure and would then be able to be analyzed against a lexicon record or word list. Client account passwords are usually hashed or encoded when sent on the system to counteract unapproved get to and utilize. In the event that the secret key is secured by encryption or hashing, unique devices in the programmer's toolbox can be utilized to break the calculation. Another Passive Online Attacks is known as man-in-the-center (MITM). In a MITM assault, the programmer blocks the validation demand and advances it to the server. By embedding a sniffer between the customer and the server, the programmer can sniff the two associations, what's more, catch passwords simultaneously. A replay Passive Online Attacks is additionally a  Passive Online Attacks ; it happens when the programmer captures the secret key on the way to the confirmation server and after that catches and resends the validation parcels for later validation. In this way, the programmer doesn't need to break the secret key or take in the watchword through MITM but instead catches the watchword and reuses the secret key validation parcels later to confirm as the customer.

 Examples of a Passive Attack

  •  Tapping

            Checking decoded correspondences, for example, messages or phone calls.

  •  Encryption

             Blocking scrambled data streams and attempting to break the encryption. 

  • Scanning

            Examining a gadget associated with the web for vulnerabilities, for example, 
             open ports or a  powerless working framework rendition. 

  •  Traffic Analysis

           Observing web movement to construct information, for example, who is going to
what site.
