Types of Network Attacks Essay Example for Free

Types of Ne twork Attacks showA Denial-of- swear out (DoS) blast is mounted with the objective of causing a negative imp strike on the effect of a computer or network. It is also known as network saturation advance or bandwidth consumption attack. Attackers make DoS attacks by sending a large number of protocol packets to a network. The problems caused by a DoS attack are as follows * Saturate network resources. * Disrupt connections surrounded by two computers, thereby preventing confabulations between services.Disrupt services to a specific computer. Man-in-the-middle Man-in-the-middle attacks occur when an assailant successfully inserts an intermediary bundle or program between two communicating hosts. The intermediary software or program allows attackers to listen to and modify the communication packets passing between the two hosts. The software intercepts the communication packets and then sends the information to the receiving host. The receiving host responds to the software, presuming it to be the legitimate client.Replay Attack A replay attack is a figure of attack in which attackers capture packets containing passwords or digital signatures whenever packets pass between two hosts on a network. In an attempt to obtain an authenticated connection, the attackers then resend the captured packet to the system. In this type of attack, the attacker does not know the actual password, but can simply replay the captured packet. Distributed Denial of Service (DDOS) In the distributed denial of service (DDOS) attack, an attacker uses multiple computers throughout the network that it has previously infected.Such computers act as zombies and work together to send out bogus messages, thereby increasing the amount of imitation traffic. The major advantages to an attacker of using a distributed denial-of-service attack are that multiple machines can generate much attack traffic than one machine, multiple attack machines are harder to turn off than one attack machine, and that the behavior of each attack machine can be stealthier, making it harder to track down and debar down. TFN, TRIN00, etc. are tools used for the DDoS attack.
