%save as AdjustMinValue.m

%Matlab function that takes three arguments

%called number of samples count, user samples

%and min vlaue and then returns a data samples

%that contains values which are double of usersamples

%that less than min vlaue

function dataSamples=AdjustMinValue(numberSamples, userSamples, minValue)

dataSamples=userSamples;

%for loop

for i=1:numberSamples

%checking if dataSamples value at index,i

%is less than minValue

if dataSamples(i)<minValue

%set double of dataSamples value

dataSamples(i)= 2*dataSamples(i);

end

Sample output:

Note:

File name and calling method name must be same

Answer:

4. A Denial of Service attack (DDOS attack).

Explanation:

A DDOS attack is a malicious attempt to disrupt the normal traffic to a service.

In essence, it sends an enormous amount of requests to the service, until the server is overwhelmed because it can't handle that much traffic, and collapses in an overflow.

Thus, regular users are not able to access their services.

Usually, attackers use a botnet, a network of "zombie" computers that have been previously infected with a malware that allows the attacker to remotely control them, then the botnet starts to send a flood of traffic from different locations, and make the attacker difficult to detect or track.
