What functions do these WLAN applications and tools perform on WLANs: airmonng, airodump-ng, aircrack-ng, and aireplay-ng

Answer:

False

Explanation:

The private member of a class is not accessible by using the Dot notation ,however the private member are those which are not accessible inside the class they are accessible outside the class  .The public member are accessible inside the class so they are accessible by using the dot operator .

Following are the example is given below in C++ Language

#include<iostream>   // header file

using namespace std;  

class Rectangle

{    

   private:  

       double r; // private member  

   public:      

       double  area()  

       {     return 3.14*r*r;  

       }        

};  

int main()  

{    

  Rectangle r1;// creating the object  

   r1.r = 3.5;  

 double t= r1.area(); // calling

cout<<" Area is:"<<t;  

   return 0;  

}  

Output:

compile time error is generated

The correct program to access the private member of class is given below

#include<iostream>   // header file

using namespace std;  

class Rectangle

{    

   private:  

       double r; // private member  

   public:      

       double  area()  

       {    

r1=r;

double t2=3.14*r2*r2;

return(t2); // return the value  

       }        

};  

int main()  

{    

  Rectangle r1;// creating the object  

   r1.r = 1.5;  

 double t= r1.area(); // calling

cout<<" Area is:"<<t;  

   return 0;  

}  

Therefore the given statement is False

Answer: symmetric encryption

Explanation:

The Secure Sockets Layer (SSL) protocol is required by the Web servers and the web browsers in order to protect the data of the users during transfer through the creation of an encrypted channel that is unique for private communications that occur over the Internet.

The Secure Sockets Layer relies on the encryption in order to secure the link that exists between the client and the server which is the website.

This implies that the encryption and also the decryption of the data will be done using a cryptographic key that is shared. The cryptographic key will be generated and shared on accordance with transport layer security handshake.

Answer:

A) Violation of Confidentiality and Source Integrity:

Passwords are very confidential information and are usually protected by both the owner and the ower of the system (which in this case is Yahoo). To obtain the passwords, the hacker had to illegally gain access to the source of the data which is on Yahoo servers. Hence a breach of confidentiality and lack of adequate integrity on the part of Yahoo.

B) Source Integrity: Anthony accidentally cuts the electricity from the server room. Why would he be able to do that? how did he gain access into the server room? This speaks to source integrity. People should not be able to access the server room except they are authorised.

C) Source Integrity and Confidentiality: NSA finds an efficient method to break AES. AES refers to the Advanced Encryption Standard. AES is a symmetric encryption technology known as a block cipher.

It is used by the United States Government for the classification of information. Their ability to break this code speaks to Violation of Source Integrity. In this case, they haven't exactly hacked any document. However, any document that was encrypted using this technology is already compromised at the source.

D)   Anna registers the domain name, "JohnSmith" and refuses to let John Smith buy or use the domain name: Violation of Availability.

It is assumed here that John Smith was the original owner of the domain but it was highjacked at expiration and registered by Anna. This kind of breach is called Violation of Availability of the domain name.

E) Some malware encrypts the victim’s hard drive with a secret key and a criminal asks for a ransom to decrypt.

This move is called the Ransomeware attack. The Integrity of the source of information (which is the hard drive) is already compromised. This is a combination of Source Integrity or availability and confidentiality violation.

F) The wiretapping of a cell phone is a breach of confidentiality and data integrity.

G) when there is a vulnerability in a system or software that is unknown to those who should be interested, it is called a Zero-Day vulnerability. Where there is a Zero-Day vulnerability there could be a violation of confidentiality, data integrity, source data and or it's availability.

Answer: (B): Round Robin

Explanation: Load Balancing refers to the systemic and effective distribution of network or application traffic across multiple severs in a sever farm. Every algorithm that balances load sits between the client's device and the back end severs.

Load Balancers are majorly used to increase the reliability and capacity of applications.

Round Robin is a type of algorithm that can be used to upgrade a website with load balancing features. It is the most widely used load balancing algorithm and it is a simple way to distribute requests across a group of servers.

The type of technology an IT engineer that is planning a website upgrade with load balancing features would use is: D) Reverse Proxy.

A website can be defined as a collective name used to describe series of web pages that are linked together with the same domain name.

A web server is a type of computer that run websites and distribute web pages as they are being requested over the internet by end users (clients).

Basically, when an end user (client) request for a website by adding or typing the uniform resource locator (URL) on the address bar of a web browser; a request is sent to the internet to view the corresponding web pages (website) associated with that particular address (domain name).

In Computer Networking, a single server can be configured to appear as an endpoint for multiple servers acting behind it through the use of a reverse proxy.

Hence, a reverse proxy is a type of server that is placed right in front of other servers such as a web server and it is typically configured to forward or route an end user's requests to those multiple servers sitting behind it.

Furthermore, when a reverse proxy is properly configured, it helps to ensure security, reliability and optimum performance of a network through load balancing.

Therefore, server load balancing is a process that allows the even distribution of network traffic across multiple servers and it involves the use of a technology referred to as a reverse proxy.

Here is the modified DemoSalesperson2

public class DemoSalesperson2{ // class DemoSalesperson2

public static void main(String[] args) { //start of main() function body

SalesPerson[] sp = new SalesPerson[10]; // creates an array of SalesPerson object named sp

int start_id =111; // assign 111 to starting id number

double start_sal=25000; //assign 25000 to starting salary means salary will start from amount 25000

 for (int i =0; i<sp.length; i++) { //loop iterates until the value of loop variable i remains less then length of the array object sp

  sp[i] =new SalesPerson(start_id+i,start_sal+5000*(i)); /*at each iteration  ID number from 111 through 120 and a sales value that ranges from $25,000 to $70,000, increasing by $5,000 for each successive is displayed using object array sp[] which calls the SalesPerson constructor to access id and sales */

 System.out.println(sp[i].getId()+"   "+sp[i].getAnnualSales() );  } } } /*uses object sp of class SalesPerson to access the methods getId which returns the id and getAnnualSales method which returns the annual sales, to display id and annual sales */

Explanation:

The question first requires a SalesPerson class with these requisites:

Class name: Salesperson.

Data fields for Salesperson: int ID number , double annual sales amount.

Methods: constructor SalesPerson() that requires values for both data fields, as well as get and set methods for each of the data fields.

So according to the complete question's requirement, I have implemented SalesPerson class:

public class SalesPerson {   // class name

//data members: integer type id variable and double type sales variable

   private int id;  

   private double sales;  

   public SalesPerson(int id_no, double annual_sales) {   //constructor that requires values for id and sales

       id = id_no;  

       sales = annual_sales;     }  

   public int getId() {   //accessor getId() method to get or access the value of id data field

       return id;     }  

   public void setId(int id_no) {   //mutator setId to set the value of id data field

       id = id_no;     }  

   public double getAnnualSales() {   //accessor getAnnualSales() method to get or access the value of sales data field

       return sales;     }  

   public void setAnnualSales(double annual_sales) { //mutator setAnnualSales to set the value of sales data field

       sales = annual_sales;     }  }

However you can use my DemoSalesperson2 application for your own SalesPerson class.

Now I will explain the working of for loop used in DemoSalesperson2

Iteration 1:

i=0

i<sp.length is true because length of sp[] is 10 so i<10

This means the body of for loop will execute.

The statement inside the body of for loop is :

 sp[i] =new SalesPerson(start_id+i,start_sal+5000*(i));

class SalesPerson constructor is used to access the data members of SalesPerson class

start_id = 111

start_sal=25000

start_id+i = 111 + 0 = 111

start_sal+5000*(i) = 25000 + 5000 (0) = 25000

The values 111 and 25000 are stored to sp[0] means at the first index of the sp array.

System.out.println(sp[i].getId()+"   "+sp[i].getAnnualSales() );  

This statement uses sp object to get access to the getId and getAnnualSales methods to print the id number and sales amount.

So the output at 1st iteration is:

111   25000.0

Iteration 1:

The value of i is incremented to 1 so now i = 1

i<sp.length is true because length of sp[] is 10 so i<10

This means the body of for loop will execute.

The statement inside the body of for loop is :

 sp[i] =new SalesPerson(start_id+i,start_sal+5000*(i));

class SalesPerson constructor is used to access the data members of SalesPerson class

start_id = 111

start_sal=25000

start_id+i = 111 + 1 = 112

start_sal+5000*(i) = 25000 + 5000 (1) = 25000 + 5000 = 30000

The values 111 and 25000 are stored to sp[1] means at the first index of the sp array.

System.out.println(sp[i].getId()+"   "+sp[i].getAnnualSales() );  

This statement uses sp object to get access to the getId and getAnnualSales methods to print the id number and sales amount.

So the output at 1st iteration is:

112   30000.0

The loop keeps iterating and the value of id is incremented by 1 and value of sales is increased by 5000 at every iteration.

This loop continues to execute until the value of i exceeds the length of sp array i.e. 10.

The values from iteration 1 to 8 following the above explanation are:

Iteration 1:

111    25000.0

Iteration 2:

112    30000.0

Iteration 3:

113    35000.0

Iteration 4:

114   40000.0  

Iteration 5:

115   45000.0  

Iteration 6:

116   50000.0                                                          

Iteration 7:

117   55000.0                                                                                                      

Iteration 8:                                                                                      

118   60000.0      

Iteration 9:                                                                                    

119   65000.0

Iteration 10:                                                                                    

120   70000.0

At iteration 11 the for loop body will not execute as value of i at 11th iteration is i = 10 and i<sp.length evaluates to false as i = sp.length because length of sp array is 10 and now the value of i is also 10. So the loop ends. Screenshot of the program and its output is attached.

Answer:

D. 10, 5.

Explanation:

Answer:

I am writing a Python program that deletes players from the file whose names whose names do not begin with a vowel which means their names begin with a consonant instead. Since the SomePlayers.txt is not provided so i am creating this file. You can simply use this program on your own file.

fileobj= open('SomePlayers.txt', 'r')  

player_names=[name.rstrip() for name in fileobj]  

fileobj.close()  

vowels = ('a', 'e', 'i', 'o', 'u','A','E','I','O','U')

player_names=[name for name in player_names  

                     if name[0] in vowels]

fileobj.close()

print(player_names)

Explanation:

I will explain the program line by line.

First SomePlayers.txt is opened in r mode which is read mode using open() method. fileobj is the name of the file object created to access or manipulate the SomePlayers.txt file. Next a for loop is used to move through each string in the text file and rstrip() method is used to remove white spaces from the text file and stores the names in player_names. Next the file is closed using close() method. Next vowels holds the list of characters which are vowels including both the upper and lower case vowels.

player_names=[name for name in player_names  

                     if name[0] in vowels]

This is the main line of the code. The for loop traverses through every name string in the text file SomePlayers.txt which was first stored in player_names when rstrip() method was used. Now the IF condition checks the first character of each name string. [0] is the index position of the first character of each players name. So the if condition checks if the first character of the name is a vowel or not. in keyword is used here to check if the vowel is included in the first character of every name in the file. This will separate all the names that begins with a vowel and stores in the list player_names. At the end the print statement print(player_names) displays all the names included in the player_names which begin with a vowel hence removing all those names do not begin with a vowel.

Answer:

I am writing a Python function:

def angry_file_finder(filename):  #function definition, this function takes file name as parameter

   with open(filename, "r") as read:  #open() method is used to open the file in read mode using object read

       lines = read.readlines()  #read lines return a list of all lines in the file

       for line in lines:  #loops through each line of the file

           if not '!' in line:   #if the line does not contains exclamation mark

               return False  # returns False if a line contains no !

   return True     # returns true if the line contains exclamation mark

print(angry_file_finder("file.txt")) call angry_file_finder method by passing a text file name to it

Explanation:

The method angry_file_finder method takes a file name as parameter. Opens that file in read mode using open() method with "r". Then it reads all the lines of the file using readline() method. The for loop iterates through these lines and check if "!" is present in the lines or not. If a line in the text file contains "!" character then function returns true else returns false.

There is a better way to write this method without using readlines() method.

def angry_file_finder(filename):

   with open(filename, "r") as file:        

       for line in file:

           if '!' not in line:  

               return False

   return True      

print(angry_file_finder("file.txt"))

Above method opens the file in read mode and just uses a for loop to iterate through each line of the file to check for ! character. The if condition in the for loop checks if ! is not present in a line of the text file. If it is not present in the line then function returns False else it returns True. This is a more efficient way to find a character in a file.

Answer:

Buffer-overflow.

Explanation:

If a program writes more information into the computer's memory than the memory was designed to hold, it is a buffer-overflow attack.

A buffer in computer technology 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 instance, 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 a buffer-overflow attack, the hacker or attacker use the extra data to influence certain unauthorized actions such as getting privy informations, damaging a file, compromising a data, corrupting a software program etc.

The common types of buffer-overflow attacks are;

1. Heap-overflow attack.

2. Stack-overflow attack.

3. Unicode-overflow attack.

4. Integer-overflow attack.

In conclusion, the buffer-overflow attack could be prevented through the randomization of the address space.

Threat assessment

Explanation:

A threat assessment deals with the potential for weaknesses within the existing infrastructure to be exploited.

Threat Assessment is further explained as the practice of determining or ascertaining the credibility and seriousness of a potential threat, and also the probability or chases of the threat will becoming a reality.

Threat assessment is separate to the more established procedure of violence-risk assessment, which seek to forcast an individual's general capacity and tendency to respond to situations violently. Instead, threat assessment aims to interrupt people on a route to commit "predatory or instrumental violence, the type of behavior connected with targeted attacks".

Answer:

Threat assessment

Explanation:

In an IT system, threat assessment is the analysis, evaluation and prevention of actions, events and operations that can greatly affect the system. It explores the potential for weaknesses within existing infrastructure to be exploited.

The threat assessment is a very important assessment that needs to be taken in virtually all domains. Here are a few reasons why it is important in an IT system;

i. Prevention of data loss

ii. Prevention of system or network of systems downtime

In carrying out threat assessment, one might need to do the following;

i. identification and prioritization of infrastructure including the software and hardware applications in the system.

ii. identification of potential threats such as system failure, natural disaster, unwanted access.

iii. identification of vulnerabilities in the system.

iv. analysing controls by determining who has access and who doesn't.

v. analysing the impact of a threat occurrence.

vi. documentation of analysis and evaluation results.

Answer:

No

Explanation:

If we used an inadmissible heuristic in A* tree search, it cannot  change the completeness of the search, and this is because as long as a heuristic function is bounded, then A* tree search would visit all the nodes available  and would definitely find a path to an existing goal

A* tree search is a  search strategy that is used to find and establish an efficient path between points, and the node in a search tree can be visited several times  as well

Question:

Which IP address is assigned to a network connection if the TCP/IP settings are set for static IP addressing and a DHCP server is running on the network?

A) An Automatic Private IP Addressing (APIPA) IP address is used

B) An error will occur and no IP address is assigned unless it is manually assigned at a command prompt

C) The IP address configured in the Internet Protocol Version 4 (TCP/IPv4) dialogue box is used

D) The IP address assigned by the DHCP server is used

Answer:

The correct answer is C

Explanation:

After the settings are changed from automatic to static, one must enter the address manually using the dialogue box and the spaces provided therein.

Any attempt to click okay will display an error requesting that the IP address be entered manually.

Static IP addresses are used when you don't want the Internet Protocol (IP) address to change.

Answer:

a) Penetration test

Explanation:

A penetration test, often referred to as a pen test, is part of important process in the development of internet facing service. It is a process of determining if vulnerabilities are actually exploitable in a particular environment.

In other words, it is a process that involves a simulated cyber attack against computer system to check for exploitable vulnerabilities or attempts to actively exploit weaknesses in an environment.

Hence, when discussing the behavior of vulnerability assessments the choice that will exploit a weakness is PENETRATION TEST.

When discussing the behavior of vulnerability assessments, the choice which will exploit a weakness is: A) Penetration test.

Cyber security can be defined as a preventive practice to systematically protect computers, software applications (programs), networks, electronic devices, servers and user data from potential attack, damage, theft or an unauthorized access, especially through the use of technologies, frameworks, integrity principles, processes, penetration test and network engineers.

A vulnerability can be defined as a weakness in an automated internal control system and security procedures, which may be exploited by an attacker (hacker) to gain unauthorized access to the data stored on a computer system or disrupt the information system.

Basically, vulnerability assessments can be used in the following ways:

A penetration test is also referred to as pen test or ethical hacking and it can be defined as a cybersecurity technique that simulates a cyber attack against a user's computer system, so as to identify, test an check for exploitable vulnerabilities in a web software, network, etc.

This ultimately implies that, a penetration test avails an end user the ability to exploit a weakness and potential security threats during vulnerability assessments.

link encryption

Explanation:

In e-mail, SSL/TLS provides link encryption.

The SSL is an acronym for Secured Socket Layer and it is one of the secured way of authenticating and encrypting data between a computer and the mail server.

In the case of a TLS, it is an acronym for Transport Layer Security and it basically is used for providing authentication and encryption of data between two communicating systems on a network.

This ultimately implies that, SSL/TLS are standard network protocols that provides data integrity and privacy to users when communicating over the internet or networking devices as they're made to encrypt user credentials and data from unauthorized access. The SSL/TLS are an application layer protocol used for the encryption of mails sent over the internet, in order to protect user information such as username and password.

price32 = float(input("Price of 32 oz size: "))

unit64 = price64/64

unit32 = price32/32

print("Unit price of 64 oz size: ", round(unit64,2))

print("Unit price of 32 oz size: ", round(unit32,2))

if unit64>unit32:

     print("Unit price of 64 oz is greater" )

else:

     print("Unit price of 32 oz is greater" )

Explanation:

This line prompts the user for the price of 64 oz size

price64 = float(input("Price of 64 oz size: "))

This line prompts the user for the price of 32 oz size

price32 = float(input("Price of 32 oz size: "))

This line calculates the unit price of 64 oz size

unit64 = price64/64

This line calculates the unit price of 32 oz size

unit32 = price32/32

This next two lines print the unit prices of both sizes

print("Unit price of 64 oz size: ", round(unit64,2))

print("Unit price of 32 oz size: ", round(unit32,2))

The next line compares the unit prices of both sizes

if unit64>unit32:

This line is executed if the unit price of 64 oz is greater than 32 oz

     print("Unit price of 64 oz is greater" )

else:

This line is executed, if otherwise

     print("Unit price of 32 oz is greater" )

Answer:

I am writing a C program:

#include <stdio.h> //to use input output functions

void printIt(double annual_in){ //function printIt

   if(annual_in >90000) //check if the income is greater than 90000

   printf("Congratulations. Doing great!"); //print this message if income value is greater than 90000

   else //if annual income is less than 90000

   printf("You WILL make $50,000, if you keep going"); } //print this message if income value is less than 90000

int main() //start of main() funciton body  

{   double income; //declares a double type variable income to hold annual income value

   printf("Enter annual income: "); //prompts user to enter annual income

   scanf("%lf",&income); //reads income value from user

   printIt(income); } // calls printIt method by passing input income to that function

Explanation:

The program is well explained in the comments mentioned with each statement of the program. The flowchart is attached.

First flowchart flow1 has a separate main program flowchart which reads the income and calls printIt function. A second flowchart is of prinIt() method that checks the input income passed by main function and displays the corresponding messages and return.

The second flowchart flow2 is the simple flowchart that simply gives functional description of the C program as flowchart is not where giving function definitions is important. Instead of defining the function printIt separately for this C program, a high-level representation of functional aspects of this program is described in second flowchart while not getting into implementation details.

Answer:

b) all the threads should be duplicated

Explanation:

The fork provides a process to start a new one, and the new process is not the same program. The exec system call com in play. Exec replaces the currently running process with information. The process is launching a new program firstly fork and create a new process. Exec load into memory. Fork copies of all attribute the new process except for memory. A clone system call implements the kernel fork. Forking provides the existing process. And the thread should be duplicated.
