Option A is corret, A Smurf attack is an attack where the attacker tries to flood the target with ICMP using spoofed ping messages. This creates a huge network traffic on victim’s network, making it work abnormally.
What is a smurf attack?Disabling computer networks is the goal of a Smurf assault, a sort of distributed denial of service (DDoS) attack. The Smurf malware achieves this by exploiting weaknesses in the Internet Control Message Protocol (ICMP) and the Internet Protocol (IP).
Why is it called a Smurf attack?The name refers to the idea of several, little attackers overpowering a much larger adversary (see Smurfs). Few networks are still subject to Smurf attacks since administrators may now render a network impervious to such misuse.

WILL GIVE BRAINLIEST!!! Please help me create an image filter in Python, for my Code HS assignment. I have tried everything and nothing will work.
Below is an example of a custom image filter that inverts the colors of an image:
from PIL import Image
def custom_filter(image):
width, height = image.size
pixels = image.load()
for x in range(width):
for y in range(height):
r, g, b = pixels[x, y]
pixels[x, y] = (255-r, 255-g, 255-b)
return image
# Usage example
original_image = Image.open("example.")
inverted_image = custom_filter(original_image)
inverted_image.save("inverted_example.")
What is the Image Filter about?The above filter uses the Python Imaging Library (PIL) to open an image file, iterate through each pixel, and invert the red, green, and blue color channels by subtracting each channel's value from 255. The resulting image will have inverted colors, like a negative film.
Therefore, You can use this as a starting point and experiment with different ways of modifying the pixels to create your own unique filter. Some ideas to try:

YOUR TASK:
Fill in the function custom_filter that takes in an Image as a parameter, and modifies the pixels in the image in some way to create a new image, then returns that modified Image!
Make your filter unique. Experiment with different ways of modifying each pixel in the image.
Here are some questions to help you brainstorm your custom filter:
• What happens if you only modify one specific color channel in each pixel (red, blue, or green)? • What happens if you swap color channels in each pixel?
• What happens if you only modify pixels if they have a certain amount of red, blue, or green? • What happens if you modify a pixel based on the pixels around it?

Consider your program for the Spinning Out section. How might you adjust your code to stop your SDV after spiraling outward on a 5 x 5 grid? How about a 7 x 7 grid?
Answer:
To adjust the code for the Spinning Out section to stop the SDV after spiraling outward on a 5 x 5 grid, you could add a conditional statement that checks the current position of the SDV and stops the program if the position exceeds the limits of the grid.
For example, you could add the following code to the end of the main loop:
if (x > 5 || y > 5) {
break;
}
This will stop the program once the SDV has moved beyond the 5 x 5 grid.
To stop the program after spiraling outward on a 7 x 7 grid, you would simply need to update the conditional statement to check for a maximum position of 7 in both the x and y directions:
if (x > 7 || y > 7) {
break;
}
This will stop the program once the SDV has moved beyond the 7 x 7 grid.

Problem Statement We have a two-dimensional board game involving snakes. The board has two types of squares on it: +'s represent impassable squares where snakes cannot go, and 0's represent squares through which snakes can move. Snakes may move in any of four directions - up, down, left, or right - one square at a time, but they will never return to a square that they've already visited. If a snake enters the board on an edge square, we want to catch it at a different exit square on the board's edge. The snake is familiar with the board and will take the route to the nearest reachable exit, in terms of the number of squares it has to move through to get there. Write a function that takes a rectangular board with only +'s and 0 's, along with a starting point on the edge of the board (given row first, then column), and returns the coordinates of the nearest exit to which it can travel. If multiple exits are equally close, give the one with the lowest numerical value for the row. If there is still a tie, give the one of those with the lowest numerical value for the column. If there is no answer, output
−1−1
The board will be non-empty and rectangular. All values in the board will be either
+
or 0 . All coordinates (input and output) are zero-based. All start positions will be 0 , and be on the edge of the board. For example,
(0,0)
would be the top left corner of any size input. Example Input Consider the following board: If a snake starts at the edge on the left (row 2 column 0 ), the snake will take the following path to another edge square (an exit) If the snake starts where the last one ended (row 5 column 2), the snake has two paths of length 5:

After embracing a BYOD policy, a company is faced with new security challenges from unmanaged mobile devices and laptops. The company’s IT department has seen a large number of the following incidents:
• Duplicate IP addresses
• Rogue network devices
• Infected systems probing the company’s network
Which of the following should be implemented to remediate the above issues? (Choose two.)
A. Port security
B. Route protection
C. NAC
D. HIPS
E. NIDS
A. Port security and C. NAC (Network Access Control) should be implemented to remediate the above issues.
What is Port security?Port security is a feature that allows an administrator to specify which devices are allowed to connect to a switch port. It can also be used to limit the number of MAC addresses that are allowed to connect to a port. This can help prevent rogue devices from connecting to the network, which can help prevent unauthorized access and protect against attacks.
What is Network Access Control (NAC)?Network Access Control (NAC) is a security solution that helps to enforce security policy compliance on all devices attempting to access a network. It is used to authenticate and authorize devices before they are allowed to connect to the network. It can also be used to block or quarantine infected or noncompliant devices to prevent them from spreading malware or compromising the security of the network. Additionally, NAC can be used to ensure that devices connecting to the network have the latest security updates and patches installed.
