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:

a. 2100

b. 2199

Explanation:

GIven that:

The file size = 1000 MB

The  payload size is  = 100 bytes

The negotiated window size is = 1000 bytes.

This implies that the sliding window can accommodate maximum number of 10 packets

The sender receives an ACK 1200 from the receiver.

Total byte of the file is :

1000 MB = 1024000000 bytes

a.

Sender receives an ACK 1200 from the receiver but still two packets are still unacknowledged

=1200 + 9 * 100

= 1200 +  900

= 2100

b. What is the last byte number that can be sent without an ACK being sent by the receiver?

b. Usually byte number starts from zero, in the first packet, the last byte will be 99 because it is in 1000th place.

Thus; the last byte number send is :

= 1200 + 10 *100 -1

= 1200 + 1000-1

= 1200 + 999

= 2199

Using Python:

def displaySubMenu():

   print("[S]top – Press ‘S’ to stop.")

Using C++ programming language:

void displaySubMenu(){

cout<<"[S]top – Press ‘S’ to stop.";}

Explanation:

The function displaySubMenu() has a print statement that prints the following message when this function is called:

[S]top – Press 'S' to stop.

You can invoke this function simply by calling this function as:

displaySubMenu()

The function doesn't take any input from the user and just displays this message on output screen whenever this function is called.

In C++ you can simply call the function using following statement:

void main(){

displaySubMenu(); }

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.

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.  

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.

Explanation:

Remember, an absolute value is the non-negative value of a number in this case the integer.

First, using the abs() function. Here's an example:

# Some random integers

variableA = -308

variableB = 301

Second, # Get the absolute values of those integers

absA = abs(variableA)

absB = abs(variableB)

Next,

# Output the results

print("Absolute values of integers with `abs()`:")

print("|", variableA, "| = ", absA, sep="")

Finally,

Use abs(variableA-variableB):

In [1]: abs(-308-301)

Out[1]: 307

The is_positive function should return True if the number received is positive, otherwise it returns None. Can you fill in the gaps to make that happen?

def is_positive(number):

       if  _____ :

           return _____

def is_positive(number):

   if (number > 0):

       return True

  else:

       return "None"

---------------------------------------------------------------------------------

print(is_positive(6))

>> True

print(is_positive(-7))

>> None

----------------------------------------------------------------------------------

The code above has been written in Python.

Now, let's explain each of the lines of the code;

Line 1: defines a function called is_positive which takes in a parameter number. i.e

def is_positive(number):

Line 2: checks if the number, supplied as parameter to the function, is positive. A number is positive if it is greater than zero. i.e

if (number > 0):

Line 3: returns a boolean value True if the number is positive. i.e

return True

Line 4: defines the beginning of the else block that is executed if the number is not positive. i.e

else:

Line 5: returns a string value "None" if the number is not positive. i.e

return "None"

All of these put together gives;

===============================

def is_positive(number):

   if (number > 0):

       return True

   else:

       return "None"

================================

An example test of the code has also been given where the function was been called with an argument value of 6 and -7. The results were True and None respectively. i.e

print(is_positive(6))   = True

print(is_positive(-7))  = None

Following are the python program to check input number is positive or negative:

def is_positive(n):#defining the method is_positive that takes one variable in parameter

   if (n > 0):#defining if block that check input number is positive

       return True#return boolean value that is True

   else:#else block

Answer:

Arkansas students have higher debt than the national average, $27,200.

Explanation:

The provided data is:

S = {24040, 19153, 26762, 31923, 31533, 34207, 14623, 24370, 31016}

In this case we need to test whether Arkansas students have higher debt than the national average at alpha equal to 0.10.

The hypothesis can be defined as follows:

H₀: Arkansas students does not have higher debt than the national average, i.e. μ ≤ $27,200.

Hₐ: Arkansas students have higher debt than the national average, i.e. μ > $27,200.

Compute the sample mean:

[tex]\bar x=\frac{1}{n}\sum X=\frac{1}{10}\times 213537=21353.70[/tex]

As the population standard deviation is provided, we will use a z-test for single mean.

Compute the test statistic value as follows:

[tex]z=\frac{\bar x-\mu}{\sigma/\sqrt{n}}=\frac{21353.70-27200}{5000/\sqrt{10}}=-3.70[/tex]

The test statistic value is -3.70.

Decision rule:

If the p-value of the test is less than the significance level then the null hypothesis will be rejected.

Compute the p-value for the test as follows:

 [tex]p-value=P(Z>-3.70)=P(Z<-3.70)=0.00011[/tex]

*Use a z-table for the probability.

The p-value of the test is 0.00011.

p-value = 0.00011 < α = 0.10

The null hypothesis will be rejected.

Thus, it can be concluded that Arkansas students have higher debt than the national average, $27,200.

   $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

   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.
