What is the most common type of network attack?

A.
Denial-of-service attacks, because they are easy to perpetrate

B.
Insider attacks, because most resources are spent defending against outside attacks

C.
Packet sniffing and other “benign” attacks, because there is no way to defend against them

D.
Brute-force password attacks, because most users do not employ good passwords

Explanation:
The denial of service (DoS) attack has become the most common network type of attack. It is the actual network being attacked here. If it was a server being attacked, or a use, then ,maybe we would say virus. But attacking the network itself, DoS can be initiated in a way that is untraceable and does not require actually breaking into the system.
Incorrect Answers:
B: It would be difficult to attack the network from the inside without being discovered as the offender.
C: Packet sniffing by a user is becoming less common as networks move to switch technology. The switch isolates the traffic so that only relevant traffic, traffic that belongs to that user, is available. Although good packet sniffing tools are not normally made available to Windows users, a snoop utility is almost standard on many Unix platforms. Besides using switch technology, there are other methods to defend the eavesdropping of the network medium.
D: If a brute force attack was successful then it would not make a difference how 1D0-470
complex the password was. But, brute force attacks take too long to come up with a solution, and there are methods that can be implemented, such as a lockout policy, to render the brute force attack useless. Complex password can be enforced by software enforced polices.
