Complete Question:
An attacker gained remote access to a user's computer by exploiting a vulnerability in a piece of software on the device. The attacker sent data that was able to manipulate the return address that is reserved to store expected data. Which vulnerability exploit resulted from the attacker's actions?
Answer:
A buffer overflow.
Explanation:
In Computer science, a buffer can be defined as a temporary area set aside for data storage. Buffers reside in the random access memory (RAM).
In the event that, a system process or program places more data (much more than what was originally or initially intended to be allocated for data storage) in a buffer, the extra data overflows. Consequently, this would result in having some of the data to flow into other buffers and thus, causing the data to be overwritten or corruption of the data being held in that buffer.
For example, we can liken a buffer-overflow to pouring water (data) into a container (program memory), once it is filled the water begins to overflow as the container has reached its maximum amount.
In this scenario, the vulnerability exploit which resulted from the attacker's actions by manipulating the return address that is reserved to store an expected amount of data is referred to as a buffer overflow.
Answer:
Punch Card Machine
Explanation:
The punch cards or the punched cards are also termed as the Hollerith cards or we also know them as the IBM cards. And they happen to be the paper cards where holes can be punched with the help of the hands or with the help of the machine for representing the computer instructions or data. And these were used on quite a large scale for inputting the data when we talk of the early computers. And this technology was developed by the Herman Hollerith.
TCP stands for Transmission Control Protocol for Communication of the Internet. It is used to interconnect network devices on the Internet and it is a connection oriented protocol which means that the connection between the devices (in our case host b and sever C) is established and maintained until they finish to exchange messages. Source port number specifies the <span>application or services on host b and destination port number on host c.
a. </span><span>The source and destination port numbers for the segments traveling from host c to host b are : source: 443 , destination: 2345.
b. From the destination port number (443) we can deduce that the server c that it is a web server. Port 443 is the standard port number for website which use SSL</span><span>(</span>Secure Sockets Layer<span>) .SSL is the standard security technology for establishing an encrypted link between a web server and a browser. </span>
