Question No: 15

A directory traversal (or path traversal) consists in exploiting insufficient security validation/sanitization of user-supplied input file names, so that characters representing quot;traverse to parent directoryquot; are passed through to the file APIs.

The goal of this attack is to order an application to access a computer file that is not intended to be accessible. This attack exploits a lack of security (the software is acting exactly as it is supposed to) as opposed to exploiting a bug in the code.

Question No: 20

Transmission control protocol accepts data from a data stream, divides it into chunks, and adds a TCP header creating a TCP segment.

The TCP header is the first 24 bytes of a TCP segment that contains the parameters and state of an end-to-end TCP socket. It is used to track the state of communication between two TCP endpoints.

For a connection to be established or initialized, the two hosts must synchronize. The synchronization requires each side to send its own initial sequence number and to receive a confirmation of exchange in an acknowledgment (ACK) from the other side

The below diagram shows the TCP Header format:

Ensurepass 2017 PDF and VCE

How many bits is a acknowledgement number?

  1. 16 bits

  2. 32 bits

  3. 8 bits

  4. 24 bits

Answer: B
