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.

Microsoft Excel is a software application or program designed and developed by Microsoft Inc., for analyzing and visualizing spreadsheet documents. There are different types of functions used in Microsoft Excel to perform specific tasks and these includes;
1. VLOOKUP function: it's an Excel function that avails end users the ability to lookup data in a table organized vertically. Thus, it's typically used for searching values in a column.
2. SUMIF function: it is an Excel function to sum cells that meet criteria such as text, dates and numbers. This function can be used with the following logical operators; <, >, and =.
3. COUNT function: it's an Excel function to find the total number of entries in a column. For example, to count the number of entries in B1:B15; COUNT(B2:B15).
4. IF function: runs a logical test and returns one value for a TRUE result, and another for a FALSE result. For example, to fail scores that are below 40; IF (A1 < 40, "Fail", "Pass").
5. HLOOKUP function: it's an Excel function that avails end users the ability to lookup data in a table organized horizontally. Thus, it's typically used for searching values in a column.
In Microsoft Excel, to insert the IF, COUNTIF, or SUM function into a cell, you should type an equal to (=) sign in the cell, followed by the name of the particular function and the relevant arguments.
For example, to use the SUMIF function, you should type; =SUMIF(A2:B5, "Peter", C1:C9).

Why are programming languages like Java and Python ideal for rapid development?
Because Java, as well as Python, are high-level programs that don't need generating or parsing, they are perfect for quick development. This implies that engineers can code a program without testing it first and then publishing it.
What are programming languages?A method of nomenclature for creating software applications is known as a computer program. The majority of formal programming are text-based, though they can also be graphical.
A substantial rise in the use of Python for machine learning and data analysis supports its status as the programming with the biggest growth. Python is a programming language with dynamic typing, while Java is a structured query and compiler language. Java is faster at play and simpler to debug thanks to this one difference, while Python is simpler to utilize and read.

Greg has a list of payments for goods brought every month for the years 2009,2010,2011, and 2012. He needs information from only the last three years. He can filter this by clicking on
Answer:
"2009" and clicking "does not equal 2009"
Explanation:
The operator, 'does not equal', is a filtering operator used to exclude a specified attribute. The 'does not equal' operator is also used to provide the definition of the condition of the filter given that there are different values of two attributes
Therefore, given that there are only four years, and Greg needs the information of the last three years, which are, 2010, 2011, and 2012, the information for the year 2009 is to be excluded
Therefore, the correct option is; "2009" and clicking "does not equal 2009"

You are concerned about attacks directed at your network firewall. You want to be able to identify and be notified of any attacks. In addition, you want the system to take immediate action to stop or prevent the attack, if possible. Which tool should you use
Answer:
Intrusion Prevention System (IPS)
Explanation:
Firewall can be defined as a network security device that monitors incoming and outgoing network traffic and decides whether to allow or block specific traffic based on a defined set of security rules.
Simply stated, a firewall is a network security protocol that monitors and controls inbound and outbound traffic based on set aside security rules.
A firewall is used to control access to a computer or network, as it creates a barrier between a computer or a network and the internet in order to protect against unauthorized access.
Basically, it is a network security device or security system pre-installed on most computers to essentially inspect data being transmitted to or from a computer
Thus, the tool you should use is an intrusion prevention system (IPS).

The head of small organization wants to install a network so that all the employees of different department can share various resources: I. What type of network he/she needs to set up in the organization? II. Name the resource that the employees will be able to share after setting up the network.
Answer:
While the Internet was evolving and creating a way for organizations to connect to each other and the world, another revolution was taking place inside organizations. The proliferation of personal computers inside organizations led to the need to share resources such as printers, scanners, and data. Organizations solved this problem through the creation of local area networks (LANs), which allowed computers to connect to each other and to peripherals. These same networks also allowed personal computers to hook up to legacy mainframe computers.
An LAN is (by definition) a local network, usually operating in the same building or on the same campus. When an organization needed to provide a network over a wider area (with locations in different cities or states, for example), they would build a wide area network (WAN).
CLIENT-SERVER
The personal computer originally was used as a stand-alone computing device. A program was installed on the computer and then used to do word processing or number crunching. However, with the advent of networking and local area networks, computers could work together to solve problems. Higher-end computers were installed as servers, and users on the local network could run applications and share information among departments and organizations. This is called client-server computing.
INTRANET
Just as organizations set up web sites to provide global access to information about their business, they also set up internal web pages to provide information about the organization to the employees. This internal set of web pages is called an intranet. Web pages on the intranet are not accessible to those outside the company; in fact, those pages would come up as “not found” if an employee tried to access them from outside the company’s network.
EXTRANET
Sometimes an organization wants to be able to collaborate with its customers or suppliers while at the same time maintaining the security of being inside its own network. In cases like this a company may want to create an extranet, which is a part of the company’s network that can be made available securely to those outside of the company. Extranets can be used to allow customers to log in and check the status of their orders, or for suppliers to check their customers’ inventory levels.
Sometimes, an organization will need to allow someone who is not located physically within its internal network to gain access. This access can be provided by a virtual private network (VPN). VPNs will be discussed further in the chapter 6 (on information security).
