Question

Cyber attacks: Explain what each of the following attacks is:

1. Replay attacks
2. Man-in-the-middle attacks
3. Keylogging

Answer 1

Answer)
Replay attacks -
A replay attack is a type of malicious attack, is a network attack using which the valid data transmission using malicious or fraudulent means is repeated or delayed, and this kind of attacks are carried out by the attacker who is intercepting the data and re-transmitting them at their own time and use. This is kind of a low level for the Man-in-the-middle attack where the attacker uses the security protocols which uses the replay of the messages and fool the participants thereby gaining trust and access.

Man-in-the-middle attacks -
The Man-in-the-middle attack is the type of attack in which the attacker intercepts the communication between 2 persons or parties and then modifies the messages between them. Thus the attacker makes a separate individual connection and relays the messages to them, where the victims think that they are in fact conversing with each other. Here the medium is controlled by the attacker and the attacker intercepts the messages which are exchanged by any of the victims.

Keylogging -
The keylogging is the type of attack which has malicious software which records the keys which are struck on the keyboard by the victims. Thus the keyboard stored is monitored and records and useful information is recorded by the attack such as user-name and passwords, or anything that is useful. Data can be retrieved by the attacks, such as confidential information and private data and information, thus making it a dangerous tool. Keyloggers can be both hardware or software.
