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

The exploitation of a buffer-overrun vulnerability in an application will MOST likely lead to:_________
SashulF [63]

Answer:

A. Arbitrary code execution

Explanation:

A buffer-overrun, also known as buffer overflow occurs when a programmer makes an error during coding, which could make his system easily susceptible to attacks from a hacker. The root cause of this problem is an overflow of data in a buffer, and programs that are written in C and C+ + are more likely to be affected by this problem.  When a buffer-overrun occurs, it would most likely lead to arbitrary code execution.

Arbitrary code execution is an uncontrolled and unrestricted coding by the attacker which alters the original coding. The attacker could input more information into the coding, which alters the original information and which would make the application porous and accessible by just anyone. It is important that programmers run regular tests on their programs, so as to detect any coding errors.
