Question

Which of the following is not a property of the denial of service (DOS) attacks?
(1) DoS prevents or inhibits the normal use of management of communications facilities
(2) DoS results in disruption of an entire network by disabling the network
(3) DoS leads to disruption of an entire network by overloading it with messages so as to degrade the performance.
(4) DoS causes passive capture of a data unit and its subsequent retransmission to produce an unauthorized effect

Answer 1

I think 2nd property

Answer 2

Answer: correct option is (1) that is DoS prevents or inhibits the normal use of management of communications facilities

Explanation:

A Denial-of-Service (DoS) attack is an attack that aims to shut down a computer or network and make it inaccessible to the intended users. DoS attacks achieve this by flooding the target with traffic or sending information that triggers a crash. In both cases, a DoS attack deprives legitimate users (ie, employees, members, or account holders) of a service or resource they have come to expect.

Victims of DoS attacks often target the web servers of major organizations such as banking, business and media companies, or government and business organizations. Although DoS attacks do not usually result in the theft or loss of important information or other assets, they can cost victims a lot of time and money to deal with.

There are two general types of DoS attacks: service flooding or service failure. Flooding attacks occur when a system receives too much traffic for the server to buffer, causing them to slow down and eventually stop. Popular flood attacks include:

The concept is to send more traffic to a network address than the programmers built the system to handle. It includes the attacks below and others designed to exploit flaws specific to certain applications or networks

ICMP Flood - Exploits misconfigured network devices by sending fake packets that ping every computer on the target network, instead of just one specific computer. The network then kicks in to amplify the traffic. This attack is also known as a smurf attack or death ping.

SYN flood - sends a connection request to the server but never completes the handshake.
