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).
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
"A Buffer overflow" vulnerability exploit resulted from the attacker's actions.
Whenever a software or an application writes too much data into a buffer, causing neighboring storage regions to have been corrupted as a consequence, this could be determined as Buffer overflow.
⇒ There are two kinds of Buffer overflow attacks such as:
Stack-based - It will become more popular to use such memory, as well as that's only available during implementation of any code.Heap-based - Those attacks seem to be more difficult to execute because they entail overflowing overall storage capacity allotted for a program further than the space needed for something like the program's present activities.Thus we can say that the correct answer is a Buffer overflow.

The program prompts the user for five to ten numbers all on one line, separated by spaces, calculates the average of those numbers, and displays the numbers and their average to the user.
The program uses methods to:
1) get the numbers entered by the user all on one line separated by spaces;
2) calculate the average of the numbers entered by the user; and
3) print the results.
The first method should take no arguments and return a String of numbers separated by spaces.
The second method should take a String as its only argument and return a double (the average).
The third method should take a String and a double as arguments but have no return value.
IF user input is: 20 40 60 80 100
Answer:
import java.util.Scanner;
public class AverageDemo
{
public static String getNumbers()
{
String numbers;
Scanner scn = new Scanner(System.in);
System.out.println("Enter five to ten numbers all on one line, separated by spaces: ");
numbers = scn.nextLine();
return numbers;
}
public static double calcAverage(String numbers)
{
String[] values = numbers.split(" ");
double total = 0;
for (int i = 0; i < values.length; i++)
{
total += Integer.parseInt(values[i]);
}
if (values.length == 0)
return 0.0;
else
return (total / values.length);
}
// Method definition of printResults: print the results
public static void printResults(String numbers, double average)
{
System.out.printf("\nThe average of the numbers %s is %.2f\n", numbers, average);
}
// main method
public static void main(String[] args)
{
// Call the methods
String numbers = getNumbers();
double average = calcAverage(numbers);
printResults(numbers, average);
}
}

What are the advantages of Radio waves over micro waves?
Answer:
radio frequencies can penetrate deeply into the material and thus heat thick products. They heat more slowly than microwaves and thus make it possible to treat more delicate products which require a slower heating.
What types of customizations have you or would you make to your operating system, and why?
Answer:
Explanation:
I have made a couple of customizations to my OS, which is Windows 10. The first being that I activated dark mode, this feature turns the entire OS into a dark-themed color, including apps and menus. This makes using the computer for extended hours much easier on the eyes. The other very important customization I added was a hover taskbar. This allows me to add many important shortcuts to the taskbar which all appear when I hover over the taskbar. It makes my desktop much cleaner and I have quick and easy access to my most important applications.
Tristen is teaching her history course. She printed off her presentation so the students could take notes. Wyatt is
teaching a science course. He wants to make sure students who do not have PowerPoint can still view the
presentation. Reed is teaching a math course online. He finds the students are very visual and wants to control the
timing per slide
Which best describes how each teacher handled their presentations?
O Tristen created handouts, Wyatt saved as a PDF, and Reed saved as a video
O Tristen created a video, Wyatt saved as a PDF, and Reed broadcasted.
O Tristen created handouts, Wyatt saved as a video, and Reed saved as a PDF.
O Tristen created a video, Wyatt broadcasted, and Reed saved as a video
Since Tristen want her students to take notes on her presentations, she should have some sort of handout.
Because Wyatt, wants to ensure that students who do not have PowerPoint can still view his presentations, converting it into a pdf is best.
Since Reed's students are very visual, converting his slides into a video will make it better for students who want to spend some time assessing some of the graphs or equations.
Thus, A is the best choice.
