Suppose you are the security manager of a company and one of your goals is to design security mechanisms based on three security goals (1) prevent the attack (2) detect the attack or (3) recover from the attack. Depending on the situation or application, you have to adopt one of these security goals. For each of the following statements, give an example of an application or situation in which the statement is true. (i). Prevention is more important than detection and recovery
(ii). Detection is more important than prevention and recovery
(iii). Recovery is more important than prevention and detection

Answer:

c. 27

Explanation:

• In recursion method, a method calls itself until a condition becomes true and returned back. In mystery(), at first time, first is 0 and last is 4. Condition is checked and 0!=4 so else part is executed in which again mystery is called with first as 1 and last 4. This will go again and again until first=4.
• When first=4 it is also equal to last so if part is executed and alpha[4] is returned which is 9, now it comes alpha[3] +9 which is 8+9 =17 .
• It is returning values to its previous calls that is why it will reduce to alpha[0]+alpha[1]+alpha[2]+17 which is nothing but sum of all elements of a alpha
• Then, 1+4+5+8+9=27.

The best method in network security to prevent intrusion are:

• Understand and use OSI Model.  
• Know the types of Network Devices.  
• Know Network Defenses.  
• Separate your Network.

How can I improve security through network design?

In the above case, the things to do is that one needs to focus on these areas for a a good network design. They are:

• Physical security.
• Use of good firewalls.
• Use the DMZ, etc.

Therefore, The best method in network security to prevent intrusion are:

• Understand and use OSI Model.  
• Know the types of Network Devices.  
• Know Network Defenses.  
• Separate your Network.

Answer:

There are many benefits to be gained from network segmentation, of which security is one of the most important. Having a totally flat and open network is a major risk. Network segmentation improves security by limiting access to resources to specific groups of individuals within the organization and makes unauthorized access more difficult. In the event of a system compromise, an attacker or unauthorized individual would only have access to resources on the same subnet. If access to certain databases in the data center must be given to a third party, by segmenting the network you can easily limit the resources that can be accessed, it also provides greater security against internal threats.

Explanation:

Answer:

Fill the blank with

public interface Nameable {

Explanation:

Required

Complete code segment with the interface definition

The given code segment is divided into three parts

1. The interface

2. The method that returns nothing

3. The method that returns string

The blank will be filled with the definition of the interface.

The definition is as follows:

public interface Nameable {

Analyzing the above definition

public -----> This represents the modifier

interface ------> This represents that the definition is an interface

Nameable ------> This represents the name of the interface

Answer:

To answer this question, i prepared a pseudocode and a program written in python;

Pseudocode begins here:

1. Start

2. Input montlySales

3. If monthlySales < 100000

3.1. Display Nothing

4. Else

4.1 Display “You earned a $5000 bonus!”

4.2 If monthlySales > 1.25 * 90000

4.2.1 Display “All employees get one day off!”

5.     Stop

Python Program starts here (See attachment for proper view of the program):

#Prompt user for input

monthlySales = float(input("Monthly Sales: "))

#Check monthlySales

if monthlySales < 100000:

     print("")

else:

     print("You earned a $5,000 bonus")

     if monthlySales > 1.25 * 90000:

           print("All Employees get the day off")

Explanation:

To answer this question, a conditional if statement is needed.

The pseudocode (and the program) starts by prompting user for input;

Then, the user input is first compared with 100,000

If it's less than 100,000; then nothing is displayes

However, if it is at least 100,000

"You earned a $5,000 bonus" is displayed

It further checks if the user input is greater than 125% of 90,000

If yes, "All Employees get the day off" is displayed else, nothing is displayed.

The pseudocode (and the program) stops execution, afterwards

Answer:

•Determine your IP address.

•Verify physical connectivity to the network.

•Check that you have a logical connection to the network.

•Find out what path network traffic takes to get to its destination.

Translate from DNS names to IP addresses.
