Answer:

2. right below the application layer

Explanation:

TLS (Transport Layer Security) is an improved and more secured version of the SSL (Secure Socket Layer) used as cryptographic protocol for providing authentication and encryption over a network. It is initialized at the transport layer of the IP stack and finalized at the application layer. In other words, it is located between the transport and application layer of the Internet protocol stack. And this is necessary so that data received in the application layer from the transport layer are protected from start to end between these two layers.

Therefore, it is safe to say that the TLS is located right below the application layer.

The answer is A, testing the circuit at the power source.

Answer:

This program is written using Python Programming language,

The program doesn't make use of comments (See explanation section for line by line explanation)

Program starts here

print("Enter elements into the list. Enter 0 to stop")

newlist = []

b = float(input("User Input: "))

while not b==0:

    newlist.append(b)

    b = float(input("User Input: "))

newlist.sort()

print("Largest element is:", newlist[-1])

Explanation:

This line gives the user instruction on how to populate the list and how to stop

print("Enter elements into the list. Enter 0 to stop")

This line creates an empty list

newlist = []

This line enables the user to input numbers; float datatype was used to accommodate decimal numbers

b = float(input("User Input: "))

The italicized gets input from the user until s/he enters 0

while not b==0:

    newlist.append(b)

    b = int(input("User Input: "))

This line sorts the list in ascending order

newlist.sort()

The last element of the sorted list which is the largest element is printed using the next line

print("Largest element is:", newlist[-1])

Answer: D.) LEFT

Explanation: LEFT is an excel function allows users to extract a specified number of characters starting from the left. The syntax goes thus :

=LEFT(text, [num_chars])

text: the original string in which characters are to be extracted.

num_chars : takes an integer, stating the number of characters to extract.

The proper function is also an excel function which sets the first character in each word to uppercase. The mid function is also used in text extraction starting from any position in the original string based on what is specified.

The LEN function is used to get the number or length of characters in a string.

Complete Question:

A network security analyst received an alert about a potential malware threat on a user’s computer. What can the analyst review to get detailed information about this compromise? Check all that apply.

A. Logs.

B. Full Disk Encryption (FDE).

C. Binary whitelisting software.

D. Security Information and Event Management (SIEM) system.

Answer:

A. Logs.

D. Security Information and Event Management (SIEM) system.

Explanation:

If a network security analyst received an alert about a potential malware threat on a user’s computer. In order to get a detailed information about this compromise, the analyst should review both the logs and Security Information and Event Management (SIEM) system.

In Computer science, logs can be defined as records of events triggered by a user, operating system and other software applications running on a computer. Log files are used to gather information stored on a computer such as user activities, system performance and software program.

Security Information and Event Management (SIEM) system is the process of gathering and integration of all the logs generated by a computer from various software application, service, process, or security tool.

These logs collected through the SIEM are shown in a format that is readable by the security analyst and this help in real-time detection of threats.

Hence, logs and SIEM systems are important tools for network security analyst for detection of threats in real-time and event management functions.

Answer:

Option (b) is the correct answer to this question.

Explanation:

AES is based on Rijndael Algorithm.

The Rijndael algorithm enables a choice of block sizes and key sizes. The choices are for each of 128, 192, or 256 bits. Once NIST implemented Rijndael for AES, it only specified one block size,128 bits, but maintained three major lengths of selection. IEEE 802.11I go a step and further limits when both the main size and length of the block for 128 bits. It simplifies deployment and relieves users during development from having to make yet again another decision.

Other options are incorrect because they are not related to the given scenario.

Explanation:

The function getNum is defined here

def getN(num):

Initialize the result of the factorial to 1

     fact = 1

Get an iteration from 1 to the user input number

     for i in range(1, 1 + num):

Multiply each number that makes the iteration

           fact = fact * i

<?php  

function word_count($string){   // function that takes a string a parameter and returns the number of words in that string

   $space = 0;   // this variable is used in order to detect space, new line and tab spaces in a string

   $words = 1; // this variable is used to identify word presence in string

   $include = $space;  //used to maintain the state of $words and $space

   $counter = 0;  // this counts the number of words in the string

   $i = 0;  //this moves through each character of the string

   while ($i < strlen($string)){  // iterates through every character of string until the last character of string is reached

       if ($string[$i] == " "||$string[$i] == "\n" || $string[$i] == "\t")  //if the space or new line or tab space is identified in the string

           $include = $space;  //set the state of include as space if the next character is a space newline or a tab space

       else if ($include == $space) {  //if next character is a word and current state i.e. $include holds $space

           $include = $words;   //  then set the state i.e. $include as $words

       ++$i;  } //returns the number of words in a string

   return $counter; }

$str = "Hello, how are you ";  //sample string

echo "Words: " . word_count($str);  // calls word_count function to return number of words in str.

?>  

Explanation:

The program has a function word_count that accepts a string as its parameter and returns the number of words in the string. In the function there are three variables $space and $words and $include used as state variables. For instance $space identifies space, new line and tab spaces in the $string so it specifies that a space has occurred. $words identifies words in the $string so it specifies that a word has occurred. $include holds this state information. $i moves through every character of the $string and when a space occurs in the $string then the state $include is set to $space. When a word occurs then state $include is set to $words. $counter variable, which is used to count the number of words is incremented to 1 when previous state is $space and next character is a word character. Every time a word is seen in the string, this variable is incremented to 1 to keep track of number of words in the string. When $i reaches the end of the string then this loop stops and counter returns the number of words in the $string.

Answer:

C. ATA Secure Erase

D. Smash the USB drive

Explanation:

Zero fill utility is a specialized way of formatting a storage device particularly secondary storage such as hard disk, flash drive e.t.c. In this process, the disk contents are overwritten with zeros. Once this has been done, undoing is essentially hard but possible. In most cases, this might just mean that the data content is corrupt and as such might still be recovered, maybe not in its pure entirety.

Formatting the drive on another hand does not essentially mean cleaning the drive and wiping off data. It just means that operating systems cannot see those data contents anymore. They are still present in the drive and can be recovered.

ATA Secure Erase is actually a way of completely and permanently erasing the content in a drive. Once the function has been done, undoing is not possible. Both the data content and even the data management table will be completely gone.

Smashing the USB drive is the surest way of cleaning data as that will permanently destroy the working components of the drive such as the memory chip. And once that happens then there's no drive let alone its contents.

a. Compile code

Explanation:

In programming process, the following are important in defining what a program is to do;

i. Purpose: The first step in writing a program is describing the purpose of the program. This includes the aim, objective and the scope of the program.  The purpose of a program should be defined in the program.

ii. Input: It is also important to specify inputs for your program. Inputs are basically data supplied to the program in order to perform a task. Valid inputs are defined in the program.

iii. Output: Many times, when inputs are supplied to a program the resulting effects are shown in the outputs. The way the output will be is defined in the program.

iv. Process: This involves the method by which inputs are being mapped into outputs. The process implements the functionality of the program by converting inputs into their corresponding outputs. The process is defined in the program.

Compile code is not a requirement in defining what a program is to do. It just allows the source code of the program to be converted into a language that the machine understands.

   spanish_month = 'Octubre'

elif month == '11':

   english_month = 'November'

   spanish_month = 'Noviembre'

elif month == '12':

   english_month = 'December'

   spanish_month = 'Diciembre'

US_English = f'{english_month} {day}'

International_Spanish = f'{day} {spanish_month}'

print(f'US English Form: {US_English}')

print(f'International Spanish Form: {International_Spanish}')

Input:

3/5

Output:

US English Form: March 5

International Spanish Form: 5 Marzo

Explanation:

You start by taking input from the user then splitting that at the '/' so that we have the date and the month in separate variables. Then we have an if statement checking to see what month is given and when the month is detected it sets a Spanish variable and an English variable then prints it to the screen.

The second "A5: B7" input is the range for the table where you need to lookup. 2 Is the number of the column from which the value is taken and 0 indicates the exact math

The VLOOKUP function is used to look up a value in a particular column.

The VLOOKUP formula to enter in cell B13 is: VLOOKUP(A11,A5:B7,2,0)

The syntax of a VLOOKUP function is:

VLOOKUP(lookup_value, cell_range, column_index, [return_value])

Where:

Explanation:

Routing is a term in engineering which involves the process of selecting a path for traffic in a network or across multiple networks. It is applicable in circuit-switched networks, such as the public switched telephone network (PSTN), and computer networks, such as the Internet. It is mostly used as a term for IP Routing.

Hence, in IP Routing, the first step is comparing the packet's destination IP address to all rows, followed by selecting the nest-match row. However, If no other row matches, the router will select the LAST row as its best match.

Here is the Python code.

import csv  

inputfile = input("Enter name of the file: ")

count = {}

with open(inputfile, 'r') as csvfile:

 csvfile = csv.reader(csvfile)

 for line in csvfile:

   for words in line:

     if words not in count.keys():

       count[words] = 1

     else:

         count[words] + 1

   print(count)

Explanation:

I will explain the code line by line.

import csv   here the css is imported in order to read the file using csv.reader() method

inputfile = input("Enter name of the file: ")  This statement takes the name of the input file from the user

count = {}  this is basically a dictionary which will store the words in the file and the number of times each word appears in the file.

with open(inputfile, 'r') as csvfile:  This statement opens the inputfile using open() method in read mode. This basically opens the input file as csv type

 csvfile = csv.reader(csvfile)  This statement uses csv.reader() method to read the csv file contents.

for line in csvfile:  This outer for loop iterates through each line of the file

for words in line:  This inner loop iterates through each word in the line

if words not in count.keys():  This if condition checks if the word is not in the dictionary already. The dictionary holds key value pair and keys() method returns a list of all the keys of dictionary

count[words] = 1  if the word is not present already then assign 1 to the count dictionary

co unt[words] + 1 if the word is already present in dictionary increment count of the words by 1. Suppose the input file contains the following words:

hello,cat,man,hey,dog,boy,Hello,man,cat,woman,dog,Cat,hey,boy

Then because of co unt[words] + 1 statement if the word appears more than once in the file, then it will not be counted. So the output will be:

{' cat': 1, ' man': 1, ' dog': 1, ' woman': 1, ' Hello': 1, ' hey': 1, ' boy': 1, 'hello': 1, ' Cat': 1}

But if you want the program to count those words also in the file that appear more than once, then change this co unt[words] + 1 statement to:  

count[words] = count[words] + 1

So if the word is already present in the file its frequency is increased by 1 by incrementing 1 to the count[words]. This will produce the following output:

{' Cat': 1, ' cat': 2, ' boy': 2, ' woman': 1, ' dog': 2, ' hey': 2, ' man': 2, ' Hello': 1, 'hello': 1}  

You can see that cat, boy, dog and hey appear twice in the file.                    

print(count) This statement prints the dictionary contents with words and their frequencies.

The program with its output is attached.

The program is an illustration of file manipulations.

File manipulations involve reading from and writing into files.

The program in Python, where comments are used to explain each line is as follows:

#This imports csv module

import csv  

#This initializes a dictionary

kounter = {}

#This gets input for the file name

fname = input("Filename: ")

#This opens and iterates through the file

with open(fname, 'r') as cfile:

   #This reads the csv file

   cfile = csv.reader(cfile)

   #This iterates through each line

   for line in cfile:

       #This iterates through each word on each line

       for words in line:

           #This counts the occurrence of each word

           if words not in kounter.keys():

               kounter[words] = 1

           else:

               kounter[words] + 1

#This prints the occurrence of each word

print(kounter)
