if a hacker wants to exploit the TCP three-way handshake, what is the most effective way to go about it?
goldfiish [28.3K]

The most effective way to exploit TCP three-way handshake is TCP SYN flood.

  • SYN flood attack is simply a kind of computer attack that begins with 3-way TCP handshake.
  • TCP SYN flood is also called SYN flood and it is a type of distributed Denial of Service (DDoS) attack that uses every part of the normal TCP three-way handshake to eat up resources on the known server and render it non-functional
  • With TCP SYN flood, a hacker can eat up resources of target's computer and makes it unresponsive.

From the above, we can therefore say that the most effective way to exploit TCP three-way handshake is TCP SYN flood.

Given the following function definition:
neonofarm [45]

The question is incomplete! Complete question along with its step by step answer is provided below!

Question:

Given the following function definition:

void calc (int a, int& b)

{

int c;

c = a + 2;

a = a * 3;

b = c + a;

}

x = 1;

y = 2;

z = 3;

calc(x, y);

cout << x << " " << y << " " << z << endl;

What is the output of the following code fragment that invokes calc?

a. 1 2 3

b. 1 6 3

c. 3 6 3

d. 1 14 9

e. None of these

Answer:

b. 1 6 3

Explanation:

In the given problem we have a function void calc which takes two input arguments a and b and updates its values according to following equations

c = a + 2;

a = a * 3;

b = c + a;

Then we call this function calc(x,y) by providing test values of

int x = 1;

int y = 2;

int z = 3;

and the output returns the values of x, y and z

cout << x << " " << y << " " << z << endl;

Lets find out what is happening here!

When the program runs we provide x=a=1 and y=b=2

c=a+2=1+2=3

a=a*3=1*3=3

b=c+a=3+3=6

So the updated values of a=x=3 and b=y=6?

NO!

The updated values are a=x=1 and b=y=6

WHY?

There are two ways to pass values

1. Pass by values -> value cannot change  (int a)

2. Pass by reference -> value can change (int& b)

Look at the function void calc (int a, int& b) ;

Here we are passing (int a) as a value and (int& b) as a reference, therefore x remains same x=1 and y gets changed to updated value y=6 and z remains same as z=3 since it wasnt used by function calc(x,y)

The right answer is:

b. 1 6 3

x=1, y=6, z=3

nydimaria [60]

Answers

  • OS(The Operating System) sends <em>interrupts to the processor</em> to stop whatever is being processing at that moment and computer architecture send <em>data bus</em>. This bus sends<u> data between the processor,the memory and the input/output unit.</u>
  • The operating system is a low-level software that supports a <em>computer’s basic functions</em>, such as <u>scheduling tasks and controlling peripherals</u> while the computer architecture has the <em>address bus bar</em>. This bus carries <u>signals related to addresses between the processor and the memory. </u>
  • The interface between <em>a computer’s hardware and its software</em> is its Architecture while An operating system (OS) is<u> system software that manages computer hardware and software resources and provides common services for computer programs.</u>

Explanation:

In short explanation,the Computer Architecture specifically <em>deals with whatever that's going on in the hardware part of the computer system </em>while the Operating System is the computer program <em>which has been program to execute at some instances depending on the programming instructions embedded in it</em>. An example is the MS Office.
